The Bitcoin mempool is a transient pool of unconfirmed transactions across nodes, where validation, fee-based prioritization, and propagation determine which transactions miners include in subsequent blocks, affecting throughput.
Full nodes are the backbone of Bitcoin: they validate transactions, enforce consensus rules, and store the blockchain. Learn how running one secures the network and empowers users.
Inside the Block Header, Bitcoin records key data – timestamps, previous-hash links and the Merkle root – that let nodes verify transactions and secure an immutable, verifiable chain.
Recent reports indicate that 25% of all public Bitcoin nodes now operate on Bitcoin Knots, signaling a notable shift in the network’s infrastructure. This change could enhance transaction efficiency and security, reflecting evolving user preferences within the Bitcoin ecosystem.
