Detailed Description

Nodes collect new transactions into a block, hash them into a hash tree, and scan through nonce values to make the block's hash satisfy proof-of-work requirements.

When they solve the proof-of-work, they broadcast the block to everyone and the block is added to the block chain. The first transaction in the block is a special one that creates a new coin owned by the creator of the block.
