The Blockchain is a public ledger recording digital transactions or events. Rather than belonging to any one person, company, or government, it’s shared by many individuals. Transactions are only recorded by consensus from the majority of users, and can never be deleted. Complete strangers can execute complex transactions transparently but with assured privacy, never exposing confidential information. Blockchain places faith and power in the interaction of the many rather than the whims of the few. This is a decentralized, crowd-sourced spreadsheet using cryptography rather than centralized authority.
