All you need to know about blockchain technology and how it enables cryptocurrency transactions and other services.
What Is Blockchain?
A blockchain is a digital ledger of transactions that is replicated and distributed across a large network of computer systems, or nodes, to record and secure information.
Each block in the blockchain contains a specific number of transactions, and each time a new block is added to the chain, it is added to every network node's ledger. This type of database system utilizes distributed ledger technology. Blockchains are considered decentralized because the data is verified by a majority of the nodes in the network, making all the network participants collectively responsible for security rather than a single central entity.
How Does Blockchain Work?
Each party involved in a blockchain transaction has a private key and a public key. These keys are strings of data used to identify a user that function like passwords. By using both private and public keys, each user involved in a blockchain transaction can authenticate themselves via digital signatures.
Once the two parties agree on the transaction, a blockchain network consensus must validate the transaction before it is added to a block in the blockchain. The people who operate the computers that serve as nodes in the blockchains are incentivized to verify transactions via rewards.
