Cryptocurrency transactions are recorded on a digital ledger called a blockchain. A blockchain is a decentralized, distributed database that stores a record of all transactions that have ever occurred on the network.
Each cryptocurrency has its own blockchain, and every transaction made on that blockchain is recorded and verified on the ledger. When a new transaction is made, it is broadcast to the network, where it is verified by network nodes through a process called consensus.
Consensus is the process by which network nodes agree on the validity of a transaction. In order to be accepted, a transaction must be verified by multiple nodes on the network, each of which checks the transaction against a set of predefined rules. These rules ensure that only valid transactions are recorded on the blockchain.
Once a transaction has been verified, it is added to a block, which is a collection of transactions. The block is then added to the blockchain, creating a permanent record of the transaction.
One of the key benefits of using a blockchain to record transactions is that it is highly secure. Because the blockchain is decentralized and distributed, it is very difficult for any one entity to alter the ledger. This makes it a very reliable and trustworthy record of transactions.
Another benefit of using a blockchain is that it is transparent. All transactions are recorded on the public ledger, making it easy for anyone to see the history of a particular cryptocurrency. This transparency helps to build trust in the system, as users can see that their transactions are being recorded accurately.
In summary, cryptocurrency transactions are recorded on a blockchain, a decentralized and distributed digital ledger. The transactions are verified by network nodes through a process called consensus and are added to a block, which is then added to the blockchain. The use of a blockchain provides a secure and transparent record of transactions.
