How does Bitcoin get validated?
Bitcoin mining is the process by which Bitcoin transactions are validated digitally on the Bitcoin network and added to the blockchain ledger. It is done by solving complex cryptographic hash puzzles to verify blocks of transactions that are updated on the decentralized blockchain ledger.
How do Bitcoin nodes validate?
A full node's main function is to independently verify the state of the Bitcoin blockchain. It does so by downloading every block and transaction and checking them against Bitcoin's consensus rules. If a transaction or block violates one of Bitcoin's consensus rules, a full node will automatically reject it.
How do Bitcoin peers find each other?
The primary way to discover peers in the bitcoin network is to connect to a list of BTC nodes that are previously connected. However, for the initial connection, the node has to use a publicly known DNS feed to retrieve a list of IP addresses of long-running stable nodes.
Who is responsible for validating Bitcoin transactions?
For a public blockchain, the decision to add a transaction to the chain is made by consensus. This means that the majority of “nodes” (or computers in the network) must agree that the transaction is valid. The people who own the computers in the network are incentivised to verify transactions through rewards.
