In contrast, a computer with the latest hardware hashes around 100 mega hashes per second . The block header is hashed, or randomly regenerated by a miner repeatedly until it meets a target number specified by the blockchain. The block header is “solved,” and a new block is created for more transactions to be encrypted and verified.
Bitcoin is pseudonymous, meaning that funds are not tied to real-world entities but rather bitcoin addresses.

That number contains all of the transaction data and information linked to the blocks before that block.
