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 ...
Similar to a transfer of value on a blockchain, deployment of a smart contract on a blockchain occurs by sending a transaction from a wallet for the blockchain. [28] The transaction includes the compiled code for the smart contract as well as a special receiver address. [28] That transaction must then be included in a block that is added to the ...

Each node maintains an independent copy of a public distributed ledger of transactions, called a blockchain, without central oversight. Transactions are validated through the use of cryptography, making it practically impossible for one person to spend another person's bitcoin, as long as the owner of the bitcoin keeps certain sensitive data ...
