Questions on: hash - страница 2

Last Updated: Monday, July 25, 2016 What is Bitcoin difficulty? Bitcoin difficulty is the mechanism that maintains the generation of a “block” at a consistent interval. A block contains new Bitcoins. A new block generates at approximately a 10-minute
Those shares did not solve the block, but they were a proof that a miner was trying to solve a block. The more shares, the more work needed to be put. Without shares, everyone would be essentially solo mining - there would be no way to prove that one
hash1 is a uint256 zero, padded to a multiple of 64 bytes by FormatHashBlocks() in main. cpp, and then reversed in 4 byte chunks. FormatHashBlocks() puts a 0x80 right after the 32 zero bytes, and a 4 byte bit count at the end (00 00 01 00, meaning 25
I understand the output of the SHA-256 hashing function is a random number between 0 and 2^256. Does the randomness of this output imply that there cannot be a, so to say, honey hole in the hashing. For instance this reddit post, http://www
Say someone locks away a wallet in durable storage for 100 years and BitCoins are still actively used. Are those BitCoins still going to be valid if they haven't been traded in/upgraded to the newer protocols? I've seen other answers on this site tha
It is not stored as part of the block data itself. Other clients reply with their list of hashes ahead of yours when you broadcast getblocks. From that list, each block header is downloaded and kept in the local block chain leveldb with the hash as a
I'm trying to walk my way through the process by which a miner hashes. Let's say the getwork request returns a data field of: 0000000244de6ceba49e1c8d438c0d8c584eefd9c8590545bfdfbf380000025c00000000fb3a091de1b4bbe5dc7acfe6bdacbc3fc3bb09bf1030adef8e28
Calculating the Z values is quite complicated for the average Joe, so i've made it easier for you. The Z values for the above example can be found on this page. http://2coin
