Full Definition

A blockchain is a distributed, immutable digital ledger that records transactions across a network of computers. Each transaction is grouped into blocks that are cryptographically linked in chronological order. Blockchains can be public (permissionless, like Ethereum) or private (permissioned). In payments, blockchain technology eliminates intermediaries, reduces settlement times from days to seconds, and provides cryptographic proof of every transaction. It is the foundational technology behind crypto payment gateways like SpacePay.
