The hash calculation is documented at Block hashing algorithm.Start there for the relatively simple basics. The basic data structures are documented in Protocol specification - Bitcoin Wiki.Note that the protocol definition (and the definition of work) more or less assumes that SHA-256 hashes are 256-bit little-endian values, rather than big-endian as the standard implies. The nonce attribute enables you to “whitelist” certain inline script and style elements, while avoiding use of the CSP unsafe-inline directive (which would allow all inline script/style), so that you still retain the key CSP feature of disallowing inline script/style in general.. So the nonce attribute is way of telling browsers that the inline contents of a particular script or style ... Nonce is a 32 bit arbitrary random number that is typically used once. In Bitcoin's mining process, the goal is to find a hash below a target number which is calculated based on the difficulty. Proof of work in Bitcoin's mining takes an input consists of Merkle Root, timestamp, previous block hash and few other things plus a nonce which is completely random number. Bitcoin Nonce is a 4-byte (32-bit) field in the input (block’s header, to be explained later…) of the SHA-256 function that is used to produce Bitcoin Hashes.The nonce needs to be set in such a way that its hashed output should have a certain number of leading zeros and to achieve these miners keep playing with this 4-byte field. Nonce reuse is typically fatal to the security of a cryptographic primitive. Cheers. $\endgroup$ – Conrad Meyer Aug 25 '18 at 18:43 $\begingroup$ Careful - a) nonces sometimes also need to be unpredictable, and b) computers operate here on Earth - hardware flaws, cosmic rays, etc that break the uniqueness of a counter are far more likely than than a birthday-problem collision in a 192-bit ...
