It is an\nconservative extension of Bitcoin's Nakamoto consensus that extends\nBitcoin's single chain algorithm to multiple chains. This allows for\nunlimited transaction throughput by horizontally scaling the number of chains.\n\nFeedback and bug reports for the content of this site are welcome.

Only the bytes from position 36 to the end are subject of the POW hash computation.\n\nThe final 8 bytes are the nonce. The creation time is encoded in bytes 44-52 (see above for details of the encoding). Miners are allowed, but not required, to update the time to reflect the solve time for the block more closely.\nA larger value for the creation time increases the accuracy of difficulty adjustment which is in the interest of miners -- the high difficulty guarantees that the outcome of the race of winning blocks is determined by actual hash power. However, blocks that are predated (i.e. have a creation time that is in the future) are rejected during block header validation. Leaving the time unchanged is a valid choice.\n\nMiners must not change or make any assumptions about the content of the \"reserved\" bytes.\n\nDefined in `Chainweb.Miner.Core`\n\n| Size | Bytes | Work Bytes | Value |\n| ---- | ------- | -----------| ----------- |\n| 4 | 0-3 | NA | chain |\n| 32 | 4-35 | NA | hash-target |\n| | | | |\n| 8 | 36-43 | 0-7 | reserved |\n| 8 | 44-51 | 8-15 | **time** |\n| 298 | 52-313 | 16-277 | reserved |\n| 8 | 314-321 | 278-285 | **nonce** |\n\ntotal: 322 bytes\n\n\nFor arithmetic comparisons the `hash-target` is interpreted as unsigned 256 bit integral number in little endian encoding.\n\n`time` is a little endian twoth complement encoded integral number that counts SI microseconds since POSIX epoch (leap seconds are ignored).
