A decentralized storage network that transforms cloud storage into an account market. Miners obtain the integrity of the original protocol by providing data storage and / or retrieval. On the contrary, customers pay miners to store or distribute data and retrieve it.
Filecoin announced, that there will be more delays before its main network is officially launched.
Filecoin developers postponed the release date of their main network to late July to late August 2020.
As mentioned in a recent announcement, the Filecoin team said that the initiative completed the first round of the internal protocol security audit. Platform developers claim that the results of the review showed that they need to make several changes to the protocol’s code base before performing the second stage of the software testing process.
Created by Protocol Labs, Filecoin was developed using File System (IPFS), which is a peer-to-peer data storage network. Filecoin will allow users to trade storage space in an open and decentralized market.
Filecoin developers implemented one of the largest cryptocurrency sales in 2017. They have privately obtained over $ 200 million from professional or accredited investors, including many institutional investors.
The main network was slated to launch last month, but in February 2020, the Philly Queen development team delayed the release of the main network between July 15 and July 17, 2020.
They claimed that the outbreak of the Coronavirus (COVID-19) in China was the main cause of the delay. The developers now say that they need more time to solve the problems found during a recent codecase audit.
The Filecoin team noted the following:
“We have drafted a number of protocol changes to ensure that building our major network launch is safe and economically sound.” The project developers will add them to two different implementations of Filecoin (Lotus and go-filecoin) in the coming weeks.
Filecoin developers conducted a survey to allow platform community members to cast their votes on three different launch dates for Testnet Phase 2 and mainnet.
The team reported that the community gave their votes. Based on the vote results, the Filecoin team announced a “conservative” estimate that the second phase of the network test should begin by May 11, 2020. The main Filecoin network may be launched sometime between July 20 and August 21, 2020.
The updates to the project can be found on the Filecoin Road Map.
Filecoin developers stated:
“This option will make us get the most important protocol changes first, and then implement the rest as protocol updates during testnet.” Filecoin is back down from the final test stage.
Another filecoin decentralized storage network provider launched its catalytic test network, the final stage of the storage network test that supports the blockchain.
In a blog post on her website, Filecoin said she will postpone the last test round until August. The company also announced a calibration period from July 20 to August 3 to allow miners to test their mining settings and get an idea of how competition conditions affected their rewards.
Filecoin had announced earlier last month that the catalytic testnet test would precede its flagship launch. The delay in the final test also means that the company has returned the main launch window between August 31 and September 21.
Despite the lack of clear incentives for miners and multiple delays, Filecoin has succeeded in attracting huge interest, especially in China. Investors remained highly speculating on the network’s mining hardware and its premium price.
Mining in Filecoin
In most blockchain protocols, “miners” are network participants who do the work necessary to promote and maintain the blockchain. To provide these services, miners are compensated in the original cryptocurrency.
Mining in Filecoin works completely differently — instead of contributing to computational power, miners contribute storage capacity to use for dealing with customers looking to store data.
Filecoin will contain several types of miners:
Storage miners responsible for storing files and data on the network. Miners retrieval, responsible for providing quick tubes for file recovery. Miners repair to be carried out.
Storage miners are the heart of the network. They earn Filecoin by storing data for clients, and computerizing cipher directories to check storage over time. The probability of earning the reward reward and transaction fees is proportional to the amount of storage that the Miner contributes to the Filecoin network, not the hash power.
Retriever miners are the veins of the network. They earn Filecoin by winning bids and mining fees for a specific file, which is determined by the market value of the said file size. Miners bandwidth and recovery / initial transaction response time will determine its ability to close recovery deals on the network.
The maximum bandwidth of the recovery miners will determine the total amount of deals that it can enter into.
In the current implementation, the focus is mostly on storage miners, who sell storage capacity for FIL.

Hardware recommendations

The current system specifications recommended for running the miner are:
Compared to the hardware requirements for running a validity checker, these standards are much higher — although they definitely deserve it. Since these will not increase in the presumed future, the money spent on Filecoin mining hardware will provide users with many years of reliable service, and they pay themselves many times. Think of investing as a small business for cloud storage. To launch a model on the current data hosting model, it will cost millions of dollars in infrastructure and logistics to get started. With Filecoin, you can do the same for a few thousand dollars.
Proceed to mining
Deals are the primary function of the Filecoin network, and it represents an agreement between a client and miners for a “storage” contract.
Once the customer decides to have a miner to store based on the available capacity, duration and price required, he secures sufficient funds in a linked portfolio to cover the total cost of the deal. The deal is then published once the mine accepts the storage agreement. By default, all Filecoin miners are set to automatically accept any deal that meets their criteria, although this can be disabled for miners who prefer to organize their deals manually.
After the deal is published, the customer prepares the data for storage and then transfers it to the miner. Upon receiving all the data, the miner fills in the data in a sector, closes it, and begins to provide proofs to the chain. Once the first confirmation is obtained, the customer can make sure the data is stored correctly, and the deal has officially started.
Throughout the deal, the miner provides continuous proofs to the chain. Clients gradually pay with money they previously closed. If there is missing or late evidence, the miner is punished. More information about this can be found in the Runtime, Cut and Penalties section of this page.
At Filecoin, miners earn two different types of rewards for their efforts: storage fees and reward prevention.
Storage fees are the fees that customers pay regularly after reaching a deal, in exchange for storing data. This fee is automatically deposited into the withdrawal portfolio associated with miners while they continue to perform their duties over time, and is locked for a short period upon receipt.
Block rewards are large sums given to miners calculated on a new block. Unlike storage fees, these rewards do not come from a linked customer; Instead, the new FIL “prints” the network as an inflationary and incentive measure for miners to develop the chain. All active miners on the network have a chance to get a block bonus, their chance to be directly proportional to the amount of storage space that is currently being contributed to the network.
Duration of operation, cutting and penalties
“Slashing” is a feature found in most blockchain protocols, and is used to punish miners who fail to provide reliable uptime or act maliciously against the network.
In Filecoin, miners are susceptible to two different types of cut: storage error cut, unanimously reduce error.
Storage Error Reduction is a term used to include a wider range of penalties, including error fees, sector penalties, and termination fees. Miners must pay these penalties if they fail to provide reliability of the sector or decide to leave the network voluntarily.
An error fee is a penalty that a miner incurs for each non-working day. Sector punishment: A penalty incurred by a miner of a disrupted sector for which no error was reported before the WindowPoSt inspection.
The sector will pay an error fee after the penalty of the sector once the error is discovered.
Termination Fee: A penalty that a miner incurs when a sector is voluntary or involuntarily terminated and removed from the network.
Cutting consensus error is the penalty that a miner incurs for committing consensus errors. This punishment applies to miners who have acted maliciously against the network consensus function.
Filecoin miners
Eight of the top 10 Felticoin miners are Chinese investors or companies, according to the blockchain explorer, while more companies are selling cloud mining contracts and distributed file sharing system hardware. CoinDesk’s Wolfe Chao wrote: “China’s craze for Filecoin may have been largely related to the long-standing popularity of crypto mining in the country overall, which is home to about 65% of the computing power on Bitcoin at discretion.”
With Filecoin approaching the launch of the mainnet blocknet — after several delays since the $ 200 million increase in 2017 — Chinese investors are once again speculating strongly about network mining devices and their premium prices.
Since Protocol Labs, the company behind Filecoin, released its “Test Incentives” program on June 9 that was scheduled to start in a week’s time, more than a dozen Chinese companies have started selling cloud mining contracts and hardware — despite important details such as economics Mining incentives on the main network are still endless.
Sales volumes to date for each of these companies can range from half a million to tens of millions of dollars, according to self-reported data on these platforms that CoinDesk has watched and interviews with several mining hardware manufacturers.
Filecoin’s goal is to build a distributed storage network with token rewards to spur storage hosting as a way to drive wider adoption. Protocol Labs launched a test network in December 2019. But the tokens mined in the testing environment so far are not representative of the true silicon coin that can be traded when the main network is turned on. Moreover, the mining incentive economics on testnet do not represent how final block rewards will be available on the main network.
However, data from Blockecoin’s blocknetin testnet explorers show that eight out of 10 miners with the most effective mining force on testnet are currently Chinese miners.
These eight miners have about 15 petabytes (PB) of effective storage mining power, accounting for more than 85% of the total test of 17.9 petable. For the context, 1 petabyte of hard disk storage = 1000 terabytes (terabytes) = 1 million gigabytes (GB).
Filecoin craze in China may be closely related to the long-standing popularity of crypt mining in the country overall, which is home to about 65% of the computing power on Bitcoin by estimation. In addition, there has been a lot of hype in China about foreign exchange mining since 2018, as companies promote all types of devices when the network is still in development.
“Encryption mining has always been popular in China,” said Andy Tien, co-founder of 1475, one of several mining hardware manufacturers in Philquin supported by prominent Chinese video indicators such as Fenbushi and Hashkey Capital.
“Even though the Velikoyen mining process is more technologically sophisticated, the idea of mining using hard drives instead of specialized machines like Bitcoin ASIC may be a lot easier for retailers to understand,” he said.
Meanwhile, according to Feixiaohao, a Chinese service comparable to CoinMarketCap, nearly 50 Chinese crypto exchanges are often somewhat unknown with some of the more well-known exchanges including Gate.io and Biki — have listed trading pairs for Filecoin currency contracts for USDT.
In bitcoin mining, at the current difficulty level, one segment per second (TH / s) fragmentation rate is expected to generate around 0.000008 BTC within 24 hours. The higher the number of TH / s, the greater the number of bitcoins it should be able to produce proportionately. But in Filecoin, the efficient mining force of miners depends on the amount of data stamped on the hard drive, not the total size of the hard drive.
To close data in the hard drive, the Filecoin miner still needs processing power, i.e. CPU or GPU as well as RAM. More powerful processors with improved software can confine data to the hard drive more quickly, so miners can combine more efficient mining energy faster on a given day.
As of this stage, there appears to be no transparent way at the network level for retail investors to see how much of the purchased hard disk drive was purchased which actually represents an effective mining force.
The U.S.-based Labs Protocol was behind Filecoin’s initial coin offer for 2017, which raised an astonishing $ 200 million.
This was in addition to a $ 50 million increase in private investment supported by notable venture capital projects including Sequoia, Anderson Horowitz and Union Square Ventures. CoinDk’s parent company, CoinDk, has also invested in Protocol Labs.
After rounds of delay, Protocol Protocols said in September 2019 that a testnet launch would be available around December 2019 and the main network would be rolled out in the first quarter of 2020.
The test started as promised, but the main network has been delayed again and is now expected to launch in August 2020. What is Filecoin mining process?
Filecoin mainly consists of three parts: the storage market (the chain), the blockecin Filecoin, and the search market (under the chain). Storage and research market in series and series respectively for security and efficiency. For users, the storage frequency is relatively low, and the security requirements are relatively high, so the storage process is placed on the chain. The retrieval frequency is much higher than the storage frequency when there is a certain amount of data. Given the performance problem in processing data on the chain, the retrieval process under the chain is performed. In order to solve the security issue of payment in the retrieval process, Filecoin adopts the micro-payment strategy. In simple terms, the process is to split the document into several copies, and every time the user gets a portion of the data, the corresponding fee is paid. Types of mines corresponding to Filecoin’s two major markets are miners and warehousers, among whom miners are primarily responsible for storing data and block packages, while miners are primarily responsible for data query. After the stable operation of the major Filecoin network in the future, the mining operator will be introduced, who is the main responsible for data maintenance.
In the initial release of Filecoin, the request matching mechanism was not implemented in the storage market and retrieval market, but the takeover mechanism was adopted. The three main parts of Filecoin correspond to three processes, namely the stored procedure, retrieval process, packaging and reward process. The following figure shows the simplified process and the income of the miners:
The Filecoin mining process is much more complicated, and the important factor in determining the previous mining profit is efficient storage. Effective storage is a key feature that distinguishes Filecoin from other decentralized storage projects. In Filecoin’s EC consensus, effective storage is similar to interest in PoS, which determines the likelihood that a miner will get the right to fill, that is, the proportion of miners effectively stored in the entire network is proportional to final mining revenue.
It is also possible to obtain higher effective storage under the same hardware conditions by improving the mining algorithm. However, the current increase in the number of benefits that can be achieved by improving the algorithm is still unknown.
It seeks to promote mining using Filecoin Discover
Filecoin announced Filecoin Discover — a step to encourage miners to join the Filecoin network. According to the company, Filecoin Discover is “an ever-growing catalog of numerous petabytes of public data covering literature, science, art, and history.” Miners interested in sharing can choose which data sets they want to store, and receive that data on a drive at a cost. In exchange for storing this verified data, miners will earn additional Filecoin above the regular block rewards for storing data. Includes the current catalog of open source data sets; ENCODE, 1000 Genomes, Project Gutenberg, Berkley Self-driving data, more projects, and datasets are added every day.
Ian Darrow, Head of Operations at Filecoin, commented on the announcement:
“Over 2.5 quintillion bytes of data are created every day. This data includes 294 billion emails, 500 million tweets and 64 billion messages on social media. But it is also climatology reports, disease tracking maps, connected vehicle coordinates and much more. It is extremely important that we maintain data that will serve as the backbone for future research and discovery”.
Miners who choose to participate in Filecoin Discover may receive hard drives pre-loaded with verified data, as well as setup and maintenance instructions, depending on the company. The Filecoin team will also host the Slack (fil-Discover-support) channel where miners can learn more.
Filecoin got its fair share of obstacles along the way. Last month Filecoin announced a further delay before its main network was officially launched — after years of raising funds.
In late July QEBR (OTC: QEBR) announced that it had ceded ownership of two subsidiaries in order to focus all of the company’s resources on building blockchain-based mining operations.
The QEBR technology team previously announced that it has proven its system as a Filecoin node valid with CPU, GPU, bandwidth and storage compatibility that meets all IPFS guidelines. The QEBR test system is connected to the main Filecoin blockchain and the already mined filecoin coin has already been tested.
“The disclosure of Sheen Boom and Jihye will allow our team to focus only on the upcoming global launch of Filecoin. QEBR branch, Shenzhen DZD Digital Technology Ltd. (“ DZD “), has a strong background in blockchain development, extraction Data, data acquisition, data processing, data technology research. We strongly believe Filecoin has the potential to be a leading blockchain-based cryptocurrency and will make every effort to make QEBR an important player when Mainecoin mainnet will be launched soon”.
IPFS and Filecoin
Filecoin and IPFS are complementary protocols for storing and sharing data in a decentralized network. While users are not required to use Filecoin and IPFS together, the two combined are working to resolve major failures in the current web infrastructure.
IPFS
It is an open source protocol that allows users to store and transmit verifiable data with each other. IPFS users insist on data on the network by installing it on their own device, to a third-party cloud service (known as Pinning Services), or through community-oriented systems where a group of individual IPFS users share resources to ensure the content stays live.
The lack of an integrated catalytic mechanism is the challenge Filecoin hopes to solve by allowing users to catalyze long-term distributed storage at competitive prices through the storage contract market, while maintaining the efficiency and flexibility that the IPFS network provides.
Using IPFS
In IPFS, the data is hosted by the required data installation nodes. For data to persist while the user node is offline, users must either rely on their other peers to install their data voluntarily or use a central install service to store data.
Peer-to-peer reliance caching data may be a good thing as one or multiple organizations share common files on an internal network, or where strong social contracts can be used to ensure continued hosting and preservation of content in the long run. Most users in an IPFS network use an installation service.
Using Filecoin
The last option is to install your data in a decentralized storage market, such as Filecoin. In Filecoin’s structure, customers make regular small payments to store data when a certain availability, while miners earn those payments by constantly checking the integrity of this data, storing it, and ensuring its quick recovery. This allows users to motivate Filecoin miners to ensure that their content will be live when it is needed, a distinct advantage of relying only on other network users as required using IPFS alone.
Filecoin, powered by IPFS
It is important to know that Filecoin is built on top of IPFS. Filecoin aims to be a very integrated and seamless storage market that takes advantage of the basic functions provided by IPFS, they are connected to each other, but can be implemented completely independently of each other. Users do not need to interact with Filecoin in order to use IPFS.
Some advantages of sharing Filecoin with IPFS:
Of all the decentralized storage projects, Filecoin is undoubtedly the most interested, and IPFS has been running stably for two years, fully demonstrating the strength of its core protocol.
Filecoin’s ability to obtain market share from traditional central storage depends on end-user experience and storage price. Currently, most Filecoin nodes are posted in the IDC room. Actual deployment and operation costs are not reduced compared to traditional central cloud storage, and the storage process is more complicated.
PoRep and PoSt, which has a large number of proofs of unknown operation, are required to cause the actual storage cost to be so, in the early days of the release of Filecoin. The actual cost of storing data may be higher than the cost of central cloud storage, but the initial storage node may reduce the storage price in order to obtain block rewards, which may result in the actual storage price lower than traditional central cloud storage.
In the long term, Filecoin still needs to take full advantage of its P2P storage, convert storage devices from specialization to civil use, and improve its algorithms to reduce storage costs without affecting user experience. The storage problem is an important problem to be solved in the blockchain field, so a large number of storage projects were presented at the 19th Web3 Summit. IPFS is an important part of Web3 visibility. Its development will affect the development of Web3 to some extent. Likewise, Web3 development somewhat determines the future of IPFS. Filecoin is an IPFS-based storage class project initiated by IPFS. There is no doubt that he is highly expected.

05-05 19:14 - 'An Island Nation with Bitcoin as the currency' (self.Bitcoin) by /u/Decamerch removed from /r/Bitcoin within 72-82min

'''
Hello all,
I am here with my plan for my [subreddit]1 Reddit Nation
If you are interested in joining a (hopefully) newly formed island nation then this is the place to be.
I have prepared a plan that explains how we will go about doing such a task. More detailed elaborations for each component of the plan will be given at request.
Obviously the first question is where we would have our island. I have identified places of interest. One place of interest is the Nation of Belize. Belize is a small nation with a low GDP of 2 Billion and they are selling off most of their island. Islands with 50-100 acres can be acquired for around 500,000; give or take 50,000. From the people (Government Officials) I have contacted, they are perfectly okay with this plan.
Now here is a 5 step proposal of how this will come to fruition (I will expand on how we will finance this)
  1. Acquire the island
  2. Set up the initial infrastructure
    1. Form of Government that I propose is a constitutional monarchy
      1. Country will be run as a democracy (two chamber form of parliament)
      2. Noble titles such as Duke, Earl, Count, Lord, Baron etc will be sold off to help initially finance the island.
    2. Establishment of the Government Building
      1. For now this is where the government will convene until more infrastructure is added and the island is improved.
      2. People will be made citizens at this location
    3. Establishment of Civil Services
      1. Waste collection, Police, Social Services
    4. Establishment of a Port
      1. This will allow supplies to enter the island.
      2. This will allow for the island to participate with the rest of the world economically(I will expand on this later).
      3. The port will function as the entrance point and exit until the runway can be constructed.
    5. Establishment of Resident Housing
      1. This temporary housing will be until the island can be developed and more permanent buildings can be put up.
      2. Resident Housing and the Government building will be set up near the port until island development is completed
    6. Set up a massive solar powered crypto mining operation to help finance further development of the island
      1. A partnership with big mining companies can be brokered to have this set up
  3. Make the Island a desirable location
    1. Set up the island as a luxury city
      1. Free housing for citizens
      2. Free healthcare for citizens
      3. Free schooling and university for citizens
    2. Build resorts and legalize gambling on the island
      1. The revenue generated from such activities will help finance further development of the island
      2. With the revenue generated from this, the island will be able to provide for the residents a luxury city
      3. The gambling industry investments will help to finance the island as well
    3. Make the island a banking haven
      1. Set up a bank on the island
      2. No KYC laws will be enforced on the island
      3. This will attract forgien investment into the island
    4. Allow cryptocurrency companies to conduct business without oversight and for miners to set up large scale operations using solar powered energy
    5. No income tax,sales tax, capital gains tax or corporate on the island
      1. Commercial businesses such as casinos, resorts, and banks will just pay slightly inflated property taxes
      2. This will help attract a lot more forgien investment as well
      3. Will attract companies to set up offices here and thus bring jobs to the island.
  4. Expand on the island infrastructure
    1. Build an airport. The islands have enough space to accommodate runways for planes even up to jumbo jets
    2. Build more free luxury housing for residents
    3. Establish schools and universities
    4. Establish libraries
    5. Establish Museums
    6. Establish a healthcare system
  5. Enjoy the luxury haven of an Island that we have built
Now for the question of how much this island will cost and how we will get the funding
According to my calculations (you can look at them below) it will cost us $2,600,000
Now in regards to how we will raise that sum
If you have made it this far, please join the [subreddit]1 for this plan
More information to come soon, thank you.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:

Bitcoin missed the opportunity to clearly represent a stable currency by defining a single "Bitcoin" as being a specific percentage of the total amount available.

For example, we could have had 100,000,000 Bitcoins total. If you had 1₿ you would always have 1/100,000,000th of the total amount of Bitcoin money available (eventually). If you had 3.14 Bitcoins, you'd have 3.14 hundred millionths of the total. With a stable currency, if you always hodl then your percentage never changes. And with measuring by percentage you always know how you were doing relative to the whole.
You can't do this with (any?) national currencies, obviously. The $1 I had when I was a teenager in 1985 might have been 0.000000005154639% of the total US money, but now that same $1 is only 0.00000000030021% (off by a factor of almost 10!). (EDIT I misread the chart, and I'm off by several zeros. Sorry!)
(Decimals like that are hard to think about, so here's that in scientific notational numbers: a 1985 dollar was about 5 × 10-9 th of the total while a 2019 dollar was about 3 × 10-10 th of the total.)
I don't know, it was just a thought I had after looking at how much money the US government keeps adding to the game, and wondering why the heck Satoshi picked such an arbitrary number like 21,000,000 as the total.
We still can see the percentage of the total that we have, but it's a messier calculation than just moving the zeros around.

12-03 20:44 - 'An Island Nation Composed of Redditors' (self.europe) by /u/OGKebabEater removed from /r/europe within 105-115min

'''
Hello all,
I am here with my plan for my [subreddit]1 Reddit Nation
If you are interested in joining a (hopefully) newly formed island nation then this is the place to be.
I have prepared a plan that explains how we will go about doing such a task. More detailed elaborations for each component of the plan will be given at request.
Obviously the first question is where we would have our island. I have identified places of interest. One place of interest is the Nation of Belize. Belize is a small nation with a low GDP of 2 Billion and they are selling off most of their island. Islands with 50-100 acres can be acquired for around 500,000; give or take 50,000. From the people (Government Officials) I have contacted, they are perfectly okay with this plan.
Now here is a 5 step proposal of how this will come to fruition (I will expand on how we will finance this)
  1. Acquire the island
  2. Set up the initial infrastructure
    1. Form of Government that I propose is a constitutional monarchy
      1. Country will be run as a democracy (two chamber form of parliament)
      2. Noble titles such as Duke, Earl, Count, Lord, Baron etc will be sold off to help initially finance the island.
    2. Establishment of the Government Building
      1. For now this is where the government will convene until more infrastructure is added and the island is improved.
      2. People will be made citizens at this location
    3. Establishment of Civil Services
      1. Waste collection, Police, Social Services
    4. Establishment of a Port
      1. This will allow supplies to enter the island.
      2. This will allow for the island to participate with the rest of the world economically(I will expand on this later).
      3. The port will function as the entrance point and exit until the runway can be constructed.
    5. Establishment of Resident Housing
      1. This temporary housing will be until the island can be developed and more permanent buildings can be put up.
      2. Resident Housing and the Government building will be set up near the port until island development is completed
    6. Set up a massive solar powered crypto mining operation to help finance further development of the island
      1. A partnership with big mining companies can be brokered to have this set up
  3. Make the Island a desirable location
    1. Set up the island as a luxury city
      1. Free housing for citizens
      2. Free healthcare for citizens
      3. Free schooling and university for citizens
    2. Build resorts and legalize gambling on the island
      1. The revenue generated from such activities will help finance further development of the island
      2. With the revenue generated from this, the island will be able to provide for the residents a luxury city
      3. The gambling industry investments will help to finance the island as well
    3. Make the island a banking haven
      1. Set up a bank on the island
      2. No KYC laws will be enforced on the island
      3. This will attract forgien investment into the island
    4. Allow cryptocurrency companies to conduct business without oversight and for miners to set up large scale operations using solar powered energy
    5. No income tax,sales tax, capital gains tax or corporate on the island
      1. Commercial businesses such as casinos, resorts, and banks will just pay slightly inflated property taxes
      2. This will help attract a lot more forgien investment as well
      3. Will attract companies to set up offices here and thus bring jobs to the island.
  4. Expand on the island infrastructure
    1. Build an airport. The islands have enough space to accommodate runways for planes even up to jumbo jets
    2. Build more free luxury housing for residents
    3. Establish schools and universities
    4. Establish libraries
    5. Establish Museums
    6. Establish a healthcare system
  5. Enjoy the luxury haven of an Island that we have built
Now for the question of how much this island will cost and how we will get the funding
According to my calculations (you can look at them below) it will cost us $2,600,000
Now in regards to how we will raise that sum
If you have made it this far, please join the [subreddit]1 for this plan
More information to come soon, thank you.

Asicpower AP9-SHA256 Review


Asicpower AP9-SHA256 Review

Bitmain is regarded as one of the most influential companies in the ASIC mining industry. It is estimated that they have manufactured approximately 53% of all mining equipment.Without including their mining profits, that’s around $140 million dollars in sales. These figures are staggering, but Bitmain’s monopoly of the Bitcoin ASIC market may come to an end, following the release of PowerAsic’s asicpower AP9-SHA256.

About the asicpower AP9-SHA256

Designed with brand new technology and boasting 94 TH/s per miner, the AP(-SHA256 is the most powerful and efficient Bitcoin miner to date.PowerAsic claims they spent $12 million dollars on research, development, and prototypes.PowerAsic also noted that their miners take advantage of ASICBOOST, an exploit of Bitcoin’s algorithm which improves mining efficiency by 20%.An unusual approach separate Powerasic’s miner to the other manufactures is the implementation of copper heat-sink claimed to have a superior thermal conductivity 69% better than aluminium. Don’t take their words for it but confirm the facts are correct on widely well known and published science documents as this one.The first batch of miners were announced and made available for order in August of 2019, with start scheduled for shipment in September, 2019.
Powerasic claims that the machines are around 40 percent more productive than the most proficient ASIC on the market, Bitmain’s Antminer S17.According to PowerAsic, they started a mining project with the aim to bring much needed competition to the market…We want to ‘make SHA256 great again.Sitting at the hefty price of $2,795.00, the powerasic AP9-SHA256 is far from affordable for the average person. Fortunately, due to the newly born rivalry between Bitmain and Powerasic, the price will probably lower with time and competition.The power supply for this unit is included and integrated in the top-box also including the controler card as a one unit. You will also get standard power cable, network cable, manual and software in the packet. In comparison to the price of the Antminer S17 , the Powerasic AP9-Sha256 is a better value.

Power Supply

The integrated PSU 3300W has a inputVoltage 220V 50Hz 30A. There are 2 fan 40mm., 1 fan 60mm to keep it cool and the power cable 3 legs following CEE 7 standard.Professional mining hardware runs optimally at 220-240V, hence why mining farms step down their own electricity supply to 220-240V. Note that 220V current is only found outside of the US – American outlets are 110V by default. Unless you want to hire an electrician, this could cause some people trouble adapt to the eficient and recomended 220V power needed, still 110V will get the job done, but they are not ideal for optimum mining performance.

Power Consumption

Thanks to the powerasic AP9-HA256’s new 7nm generation of ASIC chips, the AP9-SHA256 has become the most electrically-efficient miner on the market.Consuming merely 30.J/TB, or 2860W from the wall, the 16T is 30% more electrically-efficient than the Antminer S17.

Profitability

Powerasic ’s new ASIC technology is impressive. When compared to its closest competitor, the Antminer S17, the powerasic AP9-HA256 is the clear winner. It hashes at 94 TH/s, as opposed to the S17’s 56 TH/s. Moreover, the the AP9-HA256 consumes 30J/GH, whereas the S17 consumes 39-45J/TB.The difference in power consumption is miniscule, but when it comes to large-scale mining, the the AP9-HA256’s edge will drastically increase the profitability of a mining operation. This ASIC is profitable not only for mining on a large scale, but for the individual miner as well.Take a look at the projected mining profitability of a single miner:Note that is appears profitable even with high electricity costs ($0.1 per KW/h). With $0.05 / KW/h it’s even more profitable:📷Each powerasic AP9-HA256 will generate about $6,009 per year (calculated with 1 BTC=$10,141.5). Mining profitability may vary. You can usethis free profitability calculator to determine your projected earnings.

Is powerasic AP9-HA256 a Scam?

There is been a lot of talk on Twitter that powerasic AP9-HA256 is a scam. It appears it is not, as many users are already claiming to have received their miners.Slush, the creator ot Slush Mining Pool and the TREZOR hardware wallet, claims on Twitter that he has seen units and knows people who have had their miners delivered:

Verdict: Is The Antminer S17 Outdated?

When the first batch of Bitmain’s Antminer S17 ASICs reached the eager hands of miners, they were all the rage. The S17 was renowned as the most efficient ASIC miner on the market. Many used the S17 as the industry’s golden standard.Up until the launch of the powerasic AP9-HA256, it was the golden standard.But, now?Things have changed.Not only is the powerasic AP9-HA256 more powerful than its predecessor from Bitmain, but also more efficient, and therefore, more profitable.Ever since the announcement of the new ASIC, there was widespread speculation of its legitimacy – and rightly so.The Bitcoin community has been plagued with small, phony companies manipulating images of preexisting antminers as a ploy to hype up their fake products. Nevertheless, powerasic AP9-HA256 is taking things seriously, and their first batch of miners have lived up to expectations.The fact of the matter is, Bitmain’s most powerful and efficient antminer has been dethroned by the new reigning king of ASICs: The powerasic AP9-HA256.

Conclusion

Bitmain has dominated the ASIC market since its inception in 2013.There are a few other companies producing ASICs. However, before the creation of PowerAsics AP9-SHA256., Bitmain was the only company with a proven track record that sold efficient miners directly to the public.Powerasic AP9-HA256 has the potential to bring Bitmain’s monopoly to an end. Powerasic AP9-HA256 has a bright future ahead of them. Now that Bitmain has noteworthy competition, it will be interesting to see how it affects the market. The powerasic AP9-HA256 is the best option (for now) for anyone getting started with mining. Powerasic’s innovation should force other ASIC producers to innovate and force other companies to release new miners with better efficiency. So whether you’re buying a miner now or soon, you’re likely to benefit from the development of this new miner. For more, Visit Us: https://asicpower.net/product.php

0xBitcoin General - Weeks 45 and 46, 2018

On this day, 19th of November on the year of our Lord 2018, bitcoin dropped under five thousand United States dollars a piece. These are truly dark times that we are living in, so let us take a glance upon the recent 0xBTC developments and try to sustain ourselves on hopium until this wretched bear market comes to an end.

Some general stats (and changes since last time):
Mining difficulty: 796,213,990 (-2.67%) (next: ~718,929,110) (-10.14%)​
Estimated hashrate: 1.17 Th/s (-55.17%)

Recent events:
  1. Lodge proposed a plan to use the PoW contributed towards mining 0xBTC to secure an offchain bridge. https://medium.com/@jlogelin/arbitrary-off-chain-security-using-0xbitcoin-merged-proof-of-work-7c4ff0d07d3f
  2. 0xBitcoin was listed on Rootrex, which is a DEX that's partnered with Bithumb. Acydutz lead the initiative by simply explaining the idea behind the project and sending them a few 0xBTC to play around with. https://medium.com/@oneroot/oxbitcoin-will-get-listed-on-rootrex-at-14-00-utc-8-on-november-13-77930052fc55
  3. 0xBTC was listed on CoinCalculators.io, a site which tracks the benefits of mining various cryptos. https://www.coincalculators.io/coin.aspx?crypto=0xbitcoin-mining-calculator
  4. The sponsored article was published on CryptoCurrencyNews last week. After the community gathered 9 ETH in donations to pay for the fee, MoonBoy3000 did most of the heavy lifting in regards to the writing, with a lot of help from Mr. F. The result of that was an eloquently written article that is sure to win some more people over to our camp. https://www.ccn.com/0xbitcoin-ethereums-answer-to-bitcoins-proof-of-work/
  5. Frogger pulled some strings and got us a 0xBitcoin banner on https://coinhub.news/.
  6. The SEC has really begun cracking down on ICOs (https://www.coindesk.com/after-fridays-sec-actions-experts-say-ico-party-is-truly-over). The developments effectively mark the end of the era of centrally-generated arcade tokens, clearing the path for a fairer, more transparent method of distribution. Userbrn has written a brief article about IMOs and how they could be used to start blockchain projects in a much more accountable manner. https://medium.com/0xbitcoinfoundation/developers-need-to-consider-initial-mining-offerings-on-ethereum-28be23fa05d9
  7. Userbrn submitted a listing application to Bittrex. Don't be bothering him about the progress on it though, since no decent exchange will speculate about listings. If it goes somewhere, then I'm more than sure that we'll know.
  8. Work on the LavaWallet is currently held up by improvements that have yet to be made to Ethereum, but as soon as those get ironed out the ball will surely get rolling again. In the meantime, Infernal_toast has written this short recap of the LavaWallet: "The LavaWallet contract is a custodial token contract and it is entirely non-owned. Any user is allowed to deposit tokens inside and they will be recorded in the contracts ledger for withdraw by that user at any time. Besides just allowing users to deposit and withdraw tokens, the contract also uses ECRecover so that any tokens inside can be spent by any other pre-specified third party who can submit a signed packet of data (a Lava Packet) which had been signed by the token owner to allow this action.This means that a LavaPacket acts just like a digital check. A user creates and signs this check which specifies an amount of tokens to send to a specific party. A reward (in tokens) can be embedded as well such that anyone who pays the ether gas to submit this check back to the contract will receive. Thus, this allows users to indirectly pay for token transfers using only tokens as the fee. The third parties (relayers) will pay the ether for gas. Once a lava packet is submitted, it cannot be submitted again. One clear fault of such a system is that if anyone can be a relayer and submit a lava packet, then packets which are broadcast to everyone will be submitted by everyone in a race and only the first will be successful. The rest will just lose gas and receive no reward, making for an inefficient system. To solve this minor fault, lava packet creators must specify an address called 'relayAuthority' which is either the address of a specific account , who becomes the only valid relayers for that packet , or a specific arbitrary smart contract whose method getAuthority() is called at time of packet submission which may only return a single address at any given time. Therefore this problem is solved and at any given time, there is only a single valid relayer for any LavaPacket, as enfoced by the contract. This means there will be fewer races, fewer failed tx even with packet broadcasting ,and the power is still in the hands of the user.One such example contract for a relayAuthority has been constructed which uses Proof of Stake and cycles through valid stakers in a ~15 minute interval. LavaPacket creators may use this as a relay authority so that the packet can be submitted by any of the 15 stakers, but still at any given time only one will be a valid submitter so there are still no races, still no reason for invalid TXes."

howmanyconfs.com - How does the security of different Proof-of-Work blockchains compare to Bitcoin?

https://howmanyconfs.com

https://github.com/lukechilds/howmanyconfs.com/raw/mastescreenshot.png

How are these values calculated?

It's easy to compare blockchain hashrates when the Proof-of-Work algorithm is the same. For example if Bitcoin has a hashrate of SHA-256 @ 40 PH/s and Bitcoin Cash has a hashrate of SHA-256 @ 2 PH/s, it's easy to see that for a given period of time the Bitcoin blockchain will have 20x (40/2) the amount of work securing it than the Bitcoin Cash blockchain. Or to say that differently, you need to wait for 20x more Bitcoin Cash confirmations before an equivalent amount of work has been done compared to the Bitcoin blockchain. So 6 Bitcoin confirmations would be roughly equivalent to 120 Bitcoin Cash confirmations in the amount of work done.
However if the Proof-of-Work algorithms are different, how can we compare the hashrate? If we're comparing Bitcoin (SHA-256 @ 40 PH/s) against Litecoin (Scrypt @ 300 TH/s), the hashes aren't equal, one round of SHA-256 is not equivalent to one round of Scrypt.
What we really want to know is how much energy is being consumed to provide the current hash rate. Literal energy, as in joules or kilowatt hours. It would be great if we had a universal metric across blockchains like kWh/s to measure immutability.
However that's fairly hard to calculate, we need to know the average power consumption of the average device used to mine. For GPU/CPU mined Proof-of-Work algorithms this varies greatly. For ASIC mined Proof-of-Work algorithms it varies less, however it's likely that ASIC manufacturers are mining with next generation hardware long before the public is made aware of them, which we can't account for.
There's no automated way to get this data and no reliable data source to scrape it from. We'd need to manually research all mining hardware and collate the data ourself. And as soon as newer mining hardware comes out our results will be outdated.
Is there a simpler way to get an estimated amount of work per blockchain in a single metric we can use for comparisons?
Yeah, there is, we can use NiceHash prices to estimate the cost in $ to secure a blockchain for a given timeframe. This is directly comparable across blockchains and should be directly proportionate to kWh/s, because after all, the energy needs to be paid for in $.
How can we estimate this?
Now we have an estimated total Proof-of-Work metric measured in dollars per second ($/s).
The $/s metric may not be that accurate. Miners will mark up the cost when reselling on NiceHash and we're making the assumption that NiceHash supply is infinite. You can't actually rent 100% of Bitcoin's hashpower from NiceHash, there isn't enough supply.
However that's not really an issue for this metric, we aren't trying to calculate the theoretical cost to rent an additional 100% of the hashrate, we're trying to get a figure that allows us to compare the cost of the current total hashrate accross blockchains. Even if the exact $ value we end up with is not that accurate, it should still be proportionate to kWh/s. This means it's still an accurate metric to compare the difference in work done over a given amount of time between blockchains.
So how do we compare these values between blockchains?
Once we've done the above calculations and got a $/s cost for each blockchain, we just need to factor in the average block time and calculate the total $ cost for a given number of confirmations. Then see how much time is required on the other blockchain at it's $/s value to equal the total cost.
So to calculate how many Litecoin confirmations are equivalent to 6 Bitcoin confirmations we would do:
Therefore we can say that 240 Litecoin confirmations are roughly equal to 6 Bitcoin confirmations in total amount of work done.

Notes

$/s doesn't mean what it sounds like it means.

The $/s values should not be taken as literal costs.
For example:
This is does not mean you could do a 51% attack on Bitcoin and roll back 6 blocks for a cost of $360,000. An attack like that would be much more expensive.
The $/s value is a metric to compare the amount of work at the current hashrate between blockchains. It is not the same as the cost to add hashrate to the network.
When adding hashrate to a network the cost will not scale linearly with hashrate. It will jump suddenly at certain intervals.
For example, once you've used up the available hashrate on NiceHash you need to add the costs of purchasing ASICs, then once you've bought all the ASICs in the world, you'd need to add the costs of fabricating your own chips to keep increasing hashrate.

These metrics are measuring "work done", not security.

More "work done" doesn't necessarily mean "more security".
For example take the following two blockchains:
Bitcoin Cash has a higher $/s value than Zcash so we can deduce it has more "work done" over a given timeframe than Zcash. More kWh/s are required to secure it's blockchain. However does that really mean it's safer?
Zcash is the dominant blockchain for it's Proof-of-Work algorithm (Equihash). Whereas Bitcoin Cash isn't, it uses the same algorithm as Bitcoin. In fact just 5% of Bitcoin's hashrate is equivalent to all of Bitcoin Cash's hashrate.
This means the cost of a 51% attack against Bitcoin Cash could actually be much lower than a 51% attack against Zcash, even though you need to aquire more kWh/s of work, the cost to aquire those kWh/s will likely be lower.
To attack Bitcoin Cash you don't need to acquire any hardware, you just need to convince 5% of the Bitcoin hashrate to lend their SHA-256 hashpower to you.
To attack Zcash, you would likely need to fabricate your own Equihash ASICs, as almost all the Equihash mining hardware in the world is already securing Zcash.

Accurately calculating security is much more complicated.

These metrics give a good estimated value to compare the hashrate accross different Proof-of-Work blockchains.
However to calculate if a payment can be considered "finalised" involves many more variables.
You should factor in:
If the cryptocurrency doesn't dominate the Proof-of-Work it can be attacked more cheaply.
If the market cap or trading volume is really low, an attacker may crash the price of the currency before they can successfully double spend it and make a profit. Although that's more relevant in the context of exchanges rather than individuals accepting payments.
If the value of the transaction is low enough, it may cost more to double spend than an attacker would profit from the double spend.
Ultimately, once the cost of a double spend becomes higher than an attacker can expect to profit from the double spend, that is when a payment can probably be considered "finalised".

Bitcoin Mining Power Hits New High as Half a Million New ASICs Go Online

Bitcoin Mining Power Hits New High as Half a Million New ASICs Go Online


News by Coindesk: Wolfie Zhao
The computing power dedicated to mining bitcoin has hit yet another new high, suggesting that more than 600,000 powerful new machines may have come online in the last three months.
According to data from crypto mining pool BTC.com, bitcoin’s two-week average hash rate has crossed another major threshold, reaching 85 exahashes per second (EH/s) around 19:00 UTC last Friday. Meanwhile, mining difficulty also adjusted to a new record of nearly 12 trillion.
Notably, both figures have jumped 60 percent since June 14, the data shows.
Bitcoin’s mining difficulty — a measure of how hard it is to create a block of transactions — adjusts after 2,016 blocks, or roughly every two weeks. This is to ensure the time to produce a block remains around 10 minutes, even as the amount of hashing power, deployed by machines around the globe competing to win freshly minted bitcoins, fluctuates.
Several new models of application-specific integrated circuit (ASIC) miners hit the market over the summer, with an average hashing power around 55 tera hashes per second (TH/s).
Assuming all of the 35 EH/s of new hashing power added since mid-June came from these top-of-the-line models, a back-of-the-envelope calculation suggests that more than half a million such machines have connected to the bitcoin network. (1 EH/s =1 million TH/s)

Billion-dollar business?

These powerful ASIC miners, made by major manufacturers such as Bitmain, Canaan, InnoSilicon and MicroBT, are priced from $1,500 to $2,500 each. So if more than half a million of them were delivered, as estimated above, the leading miner makers could have made $1 billion in revenue over the past three months.
Bitcoin’s spiking hash rate and difficulty are in line with the soaring price since earlier this year, which led to increasing demand for mining equipment that has significantly outstripped supply. It’s also in part thanks to the rainy summer season in southwestern China which resulted in cheap, abundant hydroelectric power.
Further, there has also been a growing interest in Russia’s Eastern Siberia region, where the Brastsk hydropower station built in the Cold War era has been utilized to power mining farms that are estimated to account for almost 10 percent of the total computing power on the bitcoin network.
Miners in China estimated earlier this year that bitcoin’s average hash rate in the summer would break the level of 70 EH/s, which happened in August.
As such, major miner manufacturers have already sold out equipment that is due for shipment until the end of the year with customers placing pre-orders three months in advance.
TokenInsight, a startup that focuses on analysis of crypto trading and mining activities, said in a report published Friday that additional supplies of miners are expected to hit the market in the coming months.
“Following the drastic increase in bitcoin’s price, the bitcoin mining market saw significant inflation in Q2 2019. Most of the miners from various manufacturers were in serious shortage and pre-orders submitted in Q2 and Q3 are to be delivered by the end of the year,” the report states.
Therefore, the firm estimates mining difficulty will maintain its growth momentum to reach 15 trillion by the end of the year — with bitcoin’s average total hashing power crossing the threshold of 100 EH/s for the first time in its history.

The power behind Viacoin's merged mining

Let's talk about the power behind merged mining. (Auxiliary proof of work - AuxPOW)
Very simple: you mine for instance Litecoin and can mine at the same time Viacoin without losing hashrate.
But we are going to make an example.
Look at the Hashrate of Viacoin let say it is around 50 TH/s. https://chainz.cryptoid.info/via/
We take the Antminer L3+ as the miner for the whole Viacoin network.
The Antminer L3+ produces around 500 MH/s and it uses 800 watts.
This means that we need 100.000 Antminers to come at a network hashrate of 50 TH/s.The whole system of 100.000 Antminers are using 80.000.000 watts. (800 watt x 100.000)
These 80.000.000 watts x 24 Hours will result in 1920000 kWh.Let say the power costs are $0.15 per kWh is a total-cost of $12000 per HOUR !
To run the Viacoin network on your own with 50 TH/s will give you a electricity bill of $288,000.00 per DAY ! And than we even not talked about the equipment costs.
https://www.coinwarz.com/calculators/viacoin-mining-calculato?h=50000000000.00&p=80000000&pc=0.15&pf=0.00&d=329994.01552825&r=0.03906250&er=0.00008391&btcer=3714.30000000&hc=0.00
In the link i put in all the correct data and you can see it for your self, what it actually will costs to run the whole Viacoin network.
--------------------
At a price as Viacoin is today, you will lose 105 M dollar in 1 year to run the network.
If Viacoin was not AuxPOW the price for 1 Viacoin should be around 2400 dollars each, just to make the mining profitable.
And with this in mind you can see the enormous benefits behind Viacoin's merged mining.
It is not only secure but it also brings sustainability, and provides, that you are paying a fair price for your coin.
Not a single company has benefits to give Viacoin an artificial price, that's why you pay for Viacoin $0,30 and not $2400,-
And with a lot of cryptocurrencies there is a lot of money involved, and the actual buyers are paying the price.
When you buy Viacoin you know for sure that the price is originated by supply and demand, and personally with other cryptocurrencies i have so my doubts.
Other article that you might be interested in to read about merged mining:
  1. https://medium.com/altcoin-magazine/merged-mining-how-dual-mining-of-cryptocurrencies-works-98323ea57529

And than we can talk about the huge energy-costs of mining, and people will say yes but proof of stake and masternodes......
The problem with those algorithms is that it creates an elite-status to early investors, those people are untouchable until they decide to step out, and there even can be SIMILARITIES found with a ponzi-scheme, i am not saying it is a 1 on 1 ponzi.
Let say someone paid 5 dollar for a masternode and the 10th man paid $500 and the 10000th man paid $500000 dollars because this is what happens, the first people are untouchable and only generates money, the last is paying a big price and can wait 300 years to earn his investment back.Same is for proof of stake it only generates money for the team behind the coin or early investors.
It only can be considered fair and efficient when the pay-out for those algorithms is ZERO.
----------
Than you have people that say, yes but than cryptocurrency in general is a ponzi, well...
Do you consider gold as a ponzi?
I know for sure those people who bought gold, didnt get any extra gold by only holding it.And the same you can apply on POW.
1.WORK PAYS
2.DETERMINATION PAYS
But we were talking about the energy costs.
---------
Energy costs.
A lot of people are talking about the energy waste of proof of work systems, it is a point, but their is one big ''but''.
Can you name me one industry where there is no environmental footprint?
I personally realy dont know.
When you drive a car, metal must mined and gasoline must come out of the ground, when you in a plain and go on vacation etc.. etc..
Not going to deep in this stuff because it is endless.
But those same people are saying that proof of work is a waste of energy, while they fly around the world, and than they suddenly don't care about the environmental footprint they as a human leave behind and the flight industry they support?
I am in fact for a greener world, but for that, there a change is needed not only in the world industry but also in the world economy.
I see AuxPOW as a green step to an ''existing problem'' because it thrives only on the energy from other blockchains, and not use electricity on it's own.
And when the blockchain industry evolves, their will be new solutions, and when Bitcoin, Litecoin or any other can implement such new solutions, to this problem, than also Viacoin can implement it.

Thank you for reading.

How much would I have to spend to profitably mine bitcoin?

Currently (Nov. 28th 2017.) annual net earnings just with one Antminer s9 in Serbia is 8.986 USD.
As an investor or small/middle size miner you should consider: the price of bitcoin, investment for mining equipment and the price of electricity.
Superb mining equipment are ASIC processors specially made for bitcoin and alternative (all other) coins mining.
Currently (Nov. 2017.) for mining the bitcoin the best ASIK processor in the world is Antminer s9. It cost from $1.500 up to $3.500. The price varies depending on the series (each subsequent series has better performance), where it is bought (it's a big difference if you buy it directly from the manufacturer or via eBay or Amazon), shipping costs (can be from $0-200) and power supply unit cost from $105 to $200.
The cheapest electricity in Europe is in Serbia. 0,065 € (≈0,077 USD)
Source: Eurostat._YB16.png) (Eurostat is a statistical office of the European Union located in Luxembourg).
One of the essential heritage of communism that has remained in Serbia is that the price of electricity is a social category. So, in Serbia, unlike the rest of the world (perhaps in the communist countries), it is a cheaper electrical cost for domestic households than for the industry.
I decided to pinpoint exactly how much it would electricity cost if 2 Antminers s9 were mining 24/7 365 days a year. The calculation is based on Serbian Dinars. The final value is in US Dollars.
In Serbia, there are 3 zones of electricity categories depending how much of power do you consume per 30 days accounting period: green (0-350 KWh) blue (351 KWh-1.600 KWh) and red zone (more than 1.600KWh). Each zone has own price range. Each zone has night ( lower) and day ( higher) price. Night prices are calculated from 11pm-6am for each zone. Meaning, 16 hours (66,66%) during a day processor will consume higher priced el.energy and 8 hours ( 33,33%) lower priced el.energy.
One Antminer s9 processor consumes 1.400W = 1,4 KW x 24h = 33,6KW / h consumed in one day.
So two processors consume 67,2 KW / h / day
Green zone is up to 350 KWh. So, 350 KWh: 67,2 KWh / per day = 5,2083 days
5,2083 days x 24h = 124,9992 h.
33,33% of 124,9992 h = 41,6622h (lower price hours) x 1,419din. (lower price of el. in the green zone) = 59,1187 din.
66,66% of 124,9992 h = 83,3244 h (higher price hours) x 5,962din. (higher price of el. in green zone) = 496,7804 din.
The blue zone is from 350 KW to 1.600KW
1.600 KW-350 KW = 1.250 KW (the amount of electricity that can be spent in the blue zone price range)
1250KW: 67,2 KWh / per day = 18,6011 days
18,6011 days x 24h = 446,4264 h.
33,33% of 446,4264 h = 148,7939 h (lower price hours) x 2,236din. (lower price of el.price in blue zone) = 332,7032 din.
66,66% of 446,4264 h = 297,5878 h (higher price hours) x 8,943din.(higher price of el.price in blue zone) = 2.661,3280 din.
Red Zone
It remains 6,2 days in the red zone
The number of days spent in the green zone is 5,2
+
The number of days spent in the blue zone is 18,6
23,8 days spent
Calculation period 30 days -23,8 = 6,2 days in the red zone
6,2 x 24h = 148,8h
33,33% of 148,8h = 49,5950h (lower price hours) x 4,472din. (lower price of el. coast in the red zone) = 221,7890 din.
66,66% of 148,8h = 98,208h (higher priced hours) x 17,887din. (higher price of el.cost in the red zone) = 1.756,6464 din.

I'll never complain again about el.price in my country. Worldwide electricity price by region, source: statista.com
The profitability of mining bitcoin ( and other altcoins) is calculated with the power consumption calculator. Simply, chose the coin ( in this case bitcoin) enter the hash power of processor ( in this case 14 TH) and el. coast ( in this case 0,039 USD). When you put all this data, you are making just with 1 Antminer s9 $8,986 in Serbia. Power consumption calculator. Source: cryptocompare.com
Now we can do a little investment brainstorming.
Let's say you rent 10 apartments and in each, you will put two S9s. Rent in Serbia (not in Belgrade) for a flat on less attractive location, is $ 110 (can be even less), x 10 apartments that will cost you $1.100 a month.
The Internet per month is $12 x 10 flats = $120
Electricity per month is $79,45 x 10 flats = $794,5
Since this is a serious investment and business, you need 3 people (8 hours shift) for monitoring the processors pay the bills preventing possible stilling, just to make sure everything goes smoothly. The salary per person is $300, so monthly is $900. For these three persons, you can rent an apartment from where they will monitor the processors, which is an additional $ 200 per month (maybe even less).
Monthly expenses are 3.114,5 $
2 Antminers s9 are making (with current bitcoin mining difficulty, block size and price rate) $1.477,3 x 10 flats = $14.773 per month
Month Net Profit: $11.658,5 x 12 months = $139.902 Annual Net Profit
The variable cost is purchasing price of Antminer s9. From $ 1.500 to $ 3.500 (customs, delivery charges, where do you bay). We need 20 Antminers x $3.500 = $70.000
In a year (at the current bitcoin price) the gross profit is $139.902 - $70.000 ( purchasing price for 20 Antminer s9) = Net profit: $ 69.902 in the first year.
The costs could be further reduced:
~~ If you pay in advance ( 6 months or 1 year ) rant
~~ The price of an Antminer s9 is cheaper in a larger quantity order,
~~ I am not sure but, I spouse you can have better price from internet provider for large internet packet
Why two Antminers s9? Under the law, EPS ( Serbian state electrical company) is required to provide up to 30.000KWh annually to each household. The two Antminers S9 spend 24.192KWh yearly.
…..and there is more to talk about this subject.
So, if you have someone in Serbia I wish you all the best. Call me for dinner ( at least you owe me that :)) .
Or, if you are interested in this and you don’t have contacts in Serbia, you can contact me about this project. [email protected]
Stay happy,

How to get $100 million in VC funding to build an industry that makes $300 million profit without spending a dime

Yesterday I received an unexpected gift: a link to a copy of the slides of the presentation that 21inc gave to investors, apparently between October and December 2014, when they were still calling themselves "21E6".
(The sender asked to remain anonymous, and I am not sure about the copyright status of the file; so I would rather not repost it here yet. But it seems that several other people, including some of the 21inc competitors, have got a copy too; so anyone who is really interested can probably get it too.)
The slides don't have much new factual information, and basically confirm what we already guessed about the 21inc business plans. But they show that we severely underestimated their chutzpah and hype. Here are some random highlights (as far as I can decipher from the slides):
They had three relevant mining rig designs in the plans, that would require funding:
Codename Qty TH/s kW Cost Deploy Turnoff Profit($) --------------- ---- ---- --- ---- ------------ ----------- ----------- CyrusOne(v2), 7904 2.0 1.3 --- (already on) Apr 2015 ~23,000,000 IO(v1v3) 3250 5.2 1.3 2000 Jan 2015 Aug 2016 ~24,000,000 Brownfield(v3) 1900 5.5 1.3 2450 Mar 2015 > Nov 2017 ~20,000,000 
The "TH/s", "Cost", and "kW" columns are per "system", i.e. a mining unit containing many chips. The last column is the expected profit to be made from each set of mining hardware over its expected lifetime. (The slides have some other details that do not seem to be important.)
The first line is the hardware that they were mining with at the time of the presentation; that must be why the "Cost" (as far as investors are concerned) is given as zero.
The second line seems to be an upgrade of their previous mining hardware from v1 chips (which gave 2.7 PH/s total at the time) to v3 chips (which would give 17 PH/s) .
In reality, we have seen that their share of hashpower dwindled through all of 2015, and (AFAIK) they haven't mined a single block in the last six months. Were they still mining with CyrusOne on extra-life, or were they using the upgraded IO which was turned off prematurely? What happened to Brownfield?
However, their mining operations were secondary; the meat of their plan was the embedded chip, called BitSplit at the time.
The BitSPlit chip (as we suspected) was hard-wired to send 75% of the block reward to the 21inc wallet, whose address was burned in the silicon, and 25% to the user's wallet.
By my calculations, assuming 50 GH/s and no increase in the difficulty, the BitSplit would mine one block in 570 years, on average, and collect less than 2 BTC of reward in that time. So, of course, the chip was hard-wired to mine into a pool run by 21inc, that would spread the user's 25% of those 2 BTC (expected) into a daily regular trickle of a couple thousand satoshis. Their own mining operations would provide the BTC needed for the pool payouts of all the millions of chips that they expected to be running out there.
They projected to release 3 versions:
Model Qty GH/s W Cost Deploy Profit($) --------------- ---------- ---- -- ---- ------------ ------------ USB hub-charger 250,000 38 15 $35 Mar 2015 ~8,000,000 Embedded chip 1,000,000 63 15 $8 Aug 2015 ~103,000,000 BitSplit Inside 10,000,000 20 5 $0 Oct 2015 ~292,000,000 
The "Qty" is the expected number of units sold. The last column, IIUC, is the profit that 21inc expected to make from the 75% cut of the BTC produced by all the chips, over their expected lifetime.
In the above "USB hub-charger" model was a USB charging unit, roughly 3 x 2 x 1 inches, with 2 USB outputs and a mining chip inside, produced by 21inc themselves "to seed the market".
The second line, which I called "Embedded chip", seems to refer to discrete BitSplit chips provided by 21inc and included in consumer devices (like routers etc.) by OEM manufacturers.
The "BitSplit Inside" model would be the BitSplit integrated into the chipsets of other manufacturers, and manufactured by them. Its cost is listed as "$0" (for 21inc) because they expected those manufacturers to shoulder the cost of manufacturing and integrating the mining chip.
Apparently the market-seeding "USB hub-charger" was later replaced by the "Bitcoin Computer" (aka the PiTato). In one slide it is called "multifunctional BitSplit device", and depicted as a sleek shiny black box, the size of a cigarette pack, with a power cable and 2-3 USB or similar outputs. If that is supposed to be the PiTato, presumably they had not yet realized that a 15 w computer would need a cooling fan with a miniature wind tunnel on top.
In the last two entries, the manufacturers (not the device owners!) would be rewarded with the 25% slice of the BTC mined by those embedded chips. As an example, the slides say that a manufacturer who produced one quarter of the embedded BitSplits would get the 25% cut on the BTC yield of those chips, that was estimated to be between 2 and 4 million dollars per year of revenue in 2015--2018. Those numbers are based on the following predicted mean BTC prices: $350 for 2015, $1000 for 2016, $2200 for 2017, and $5500 for 2018.
So, their main business plan was fantastic: the OEM and chipset makers would pay the costs of producing and integrating the chips, the consumers would pay the cost of operating them, and 21inc would get 75% of all BTC mined by them, expected to be worth 400 million dollars.
It makes sense to invest 100 million in that plan, right?

'''
So through my business I stumbled upon an opportunity for a data center with cheap electricity. The company's name is Astra [[link]2 and its located in Trail, BC, Canada. They are offering me this deal. So since I am a bitcoin novice, do you guy have any ideas where I could advertise this deal or who would be interested? The reason why the power is so cheap it's because of its located right next to a hydroelectric-dam. The numbers are calculated when the bitcoin price was at 7600 dollars. I have photos of the data centers, and the CEO will pick up if anyone has any questions. Any tips?
* We can offer 600 BTC miners (specs 1300 Watts Power, 12 TH/s Hashing power) for $ 275/ miner ($165k USD initial investment) - these are last years miners so they are heavily discounted
* For set up, there would be a one time fee of $25,000 USD
* For power, lease space and administration we would charge $10,000 / month
* Your power costs to run the machines would be approx. $43,000/ month (would vary slightly as power is paid in CDN dollars)
* Your return rate (i.e. value of Bitcoin produced at todays rate of $7,664.51 USD) would be $54,966 USD
* So - monthly revenue from your machines would be approx. $16,466 (before admin fee - $6,466 net) Admin fee is 10 k
* This would be turn key i.e. we would set up everything for you and provide reporting etc.
* Term would need to be 12 months to start then monthly with a 2 month notice period after initial term

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For lots of additional video resources check out the videos wiki page or /BitcoinTV.
Key properties of bitcoin
  • Limited Supply - There will only ever be 21,000,000 bitcoins created and they are issued in a predictable fashion, you can view the inflation schedule here. Once they are all issued Bitcoin will be truly deflationary.
  • Open source - Bitcoin code is fully auditable. You can read the source code yourself here.
  • Accountable - The public ledger is transparent, all transactions are seen by everyone.
  • Decentralized - Bitcoin is globally distributed across thousands of nodes with no single point of failure and as such can't be shut down similar to how Bittorrent works.
  • Censorship resistant - No one can prevent you from interacting with the bitcoin network and no one can censor, alter or block transactions that they disagree with, see Operation Chokepoint.
  • Push system - There are no chargebacks in bitcoin because only the person who owns the address where the bitcoins reside has the authority to move them.
  • Low fee - Transactions fees can vary between a few cents and a few dollars depending on network demand and how much priority you wish to assign to the transaction. Most wallets calculate the fee automatically but you can view current fees here.
  • Borderless - No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.
  • Trustless - Bitcoin solved the Byzantine's Generals Problem which means nobody needs to trust anybody for it to work.
  • Pseudonymous - No need to expose personal information when purchasing with cash or transacting.
  • Secure - Encrypted cryptographically and can’t be brute forced or confiscated with proper key management such as hardware wallets.
  • Programmable - Individual units of bitcoin can be programmed to transfer based on certain criteria being met
  • Nearly instant - From a few seconds to a few minutes depending on need for confirmations. After a few confirmations transactions are irreversible.
  • Peer-to-peer - No intermediaries with a cut, no need for trusted third parties.
  • Portable - Bitcoins are digital so they are easier to move than cash or gold. They can even be transported by simply remembering a string of words for wallet recovery.
  • Scalable - Each bitcoin is divisible down to 8 decimals allowing it to grow in value while still accommodating micro-transactions.
  • Designed Money - Bitcoin was created to fit all the fundamental properties of money better than gold or fiat
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.

Where can I buy bitcoins?

BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also, check out the bitcoinity exchange resources for a larger list of options for purchases.
Bank Transfer Credit / Debit card Cash
Coinbase Coinbase LocalBitcoins
Gemini Bitstamp LibertyX
GDAX Bitit Mycelium LocalTrader
Bitstamp Cex.io BitQuick
Kraken CoinMama WallofCoins
Xapo BitcoinOTC
Cex.io
itBit
Bitit
Bitsquare
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Cashila or Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
  • If you prefer to "Be your own bank" and have direct control over your coins without having to use a trusted third party, there are many software wallet options here. If you want easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor or Ledger is recommended. A more advanced option is to secure them yourself using paper wallets generated offline. Some popular mobile and desktop options are listed below and most are cross platform.
Android iOs Desktop
Mycelium BreadWallet Electrum
CoPay AirBitz Armory
  • If you prefer to let third party "Bitcoin banks" manage your coins, try Coinbase or Xapo but be aware you may not be in control of your private keys in which case you would have to ask permission to access your funds and be exposed to third party risk.
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy
Android Android
iOS iOS

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin ?BTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (?L) or micrometre (?m)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:
  • 0.02 BTC
  • 20 mBTC
  • 20,000 bits
For more information check out the Bitcoin units wiki.
