The block time is the average time it takes for the network to generate one extra block in the blockchain. By the time of block completion, the included data becomes verifiable. In cryptocurrency, this is practically when the transaction takes place, so a shorter block time means faster transactions.
A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. [59] [61] Each block typically contains a hash pointer as a link to a previous block, [61] a timestamp, and transaction data. [62] By design, blockchains are inherently resistant to modification of the data.
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 ...
Blockchain documents and confirms pseudonymous ownership of all transactions in a verifiable and sustainable way. [2] After a transaction is validated and cryptographically verified by other participants or nodes in the network, it is made into a "block" on the blockchain. [1]
Each block contains a SHA-256 hash of the previous block, [70] chaining them in chronological order. [7]: ch. 7 [70] The blockchain is maintained by a peer-to-peer network. [25]: 215–219 Individual blocks, public addresses, and transactions within blocks are public information, and can be examined using a blockchain explorer. [71]
the block time determines how often a new block is added to the chain, the block size determines the amount of data that can be added with every block. Bitcoin has a block time of 10 minutes and a block size of 1 MB. Various increases to this limit, and proposals to remove it completely, have been proposed over bitcoin's history.

Bitcoin forks are defined variantly as changes in the protocol of the bitcoin network or as the situations that occur "when two or more blocks have the same block height". [1] A fork influences the validity of the rules. Forks are typically conducted in order to add new features to a blockchain, to reverse the effects of hacking or catastrophic ...
