Yes, to make "megablocks" viable for anything besides block chain data storage, the sigops limit would need to be changed. Simply increasing it would be the easiest option, but I suspect at least some developers would prefer to change how the sigop l
Introduction¶The word mining originates in the context of the gold analogy for crypto currencies. Gold or precious metals are scarce, so are digital tokens, and the only way to increase the total volume is through mining. This is appropriate to the e
I am confused about whether a miner chooses to wait for more transactions (more fees) or starts as soon as it receives the first transaction from the network. Once a miner has started calculating the hashes, it will queue the new transactions, correc
When a mining pool or solo miner releases a block to peers, each peer running Bitcoin-Qt/bitcoind will verify the transactions in the block before relaying the block. The SHA256 block hash is the first thing verified. The SHA256 hash that identifies
Once a miner has found a block, how easy it is for him to add or remove a tx included in that very block? It is impossible. The solved block depends on every byte of transaction data, nothing can be changed. It is important that it be this way
In a work, there are only two elements in the block header change between hash attempts. That is, NTime and Nonce. The miner starts the nonce search to get a valid share, and there are several possibilities: 1) In a single nonce range (0~2^32-1), the
People often talk about SHA256 like it's a single operation, but it isn't. Rather, the input is broken up into 64-byte chunks, and then each chunk is put into a compression function. The state of the hash partway through hashing something does not de
