The Nonce is a 32 bit number and the 2^32 number space is exhausted during mining within less than a second. The transactions (Tx0, Tx1, ...) are appended to the block. The first transaction generates new bitcoins and contains the coinbase field which includes an extraNonce to provide a larger search space for valid block hash values.
A diagram of a bitcoin transfer. The bitcoin protocol is the set of rules that govern the functioning of bitcoin.Its key components and principles are: a peer-to-peer decentralized network with no central oversight; the blockchain technology, a public ledger that records all bitcoin transactions; mining and proof of work, the process to create new bitcoins and verify transactions; and ...
A collection of bitcoin transactions prefaced by a block header, protected by proof of work, and recorded on a network of computers is called a "block". All blocks are tied together sequentially by using a cryptographic hash on the previous block and storing its output in the next.
