What technology underpins cryptocurrency transactions?
The technology that underpins cryptocurrency transactions is blockchain. Blockchain is a decentralized and distributed digital ledger that records all transactions across a network of computers. Each transaction is grouped into a block and linked to previous blocks, forming a chain. This structure ensures data integrity, transparency, and security, as once recorded, transactions cannot be altered without consensus from the network participants. The use of cryptographic algorithms secures the transactions, making blockchain a fundamental technology for cryptocurrencies like Bitcoin and Ethereum.
