What is a blockchain?

People describe blockchain technology in different ways, but at its core, a blockchain is a public digital ledger that records transactions inside a given network. These transactions are publicly verifiable and cryptographically secure. In this video, Block.one’s founder and CEO Brendan Blumer describes how blockchain is simply a secure version of the internet that enables mass scalable secure data transfers.

What is a “smart contract”?

A smart contract combines a legal contract with code to automate the execution of specific terms of an agreement between parties in an objective way. Dan Larimer, former CTO of Block.one, and Bart Wyatt, from our Engineering team, explain more in this video.
