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
I'm trying to understand the algorithm Bitcoin Core uses to sort memory pool transactions by fee. Gavin's fee rework proposal states: Next, sort all remaining memory pool transactions by fee-paid-per-kilobyte, and include as many as will fit until th
Currently no. Any "required fees" are enforced only by the client not the network or protocol. It is up to each individual miners which transactions to include in a block

Currently no. Any "required fees" are enforced only by the client not the network or protocol. It is up to each individual miners which transactions to include in a block
You can find some examples of the GetWork protocol here. Generally, the pool provides a block header that is to be hashed with various nonces, as well as some additional information, such as: hash1, which is always "0000000000000000000000000000000000
