Blockchain — definition & meaning

A shared, tamper-resistant digital ledger behind cryptocurrencies.

A blockchain is a distributed ledger that records transactions across many computers so they cannot easily be altered, removing the need for a central authority.

It is the technology that makes cryptocurrencies work. Understanding it is useful context, but knowing the tech doesn't reduce the price risk of trading crypto assets.
