Distributed Ledger

A distributed ledger is a database that is consensually shared and synchronized across multiple sites, institutions, or geographies, accessible by multiple people. Blockchains are one type of distributed ledger that stores information in blocks that are chained together using mathematical principles that are very hard to forge or corrupt. Because anyone can mathematically verify and audit transactions recorded in a blockchain, multiple participants can contribute to, or rely on, a shared blockchain to store information—such as timestamped cryptocurrency transactions—without needing to trust either each other or a mutual third party (like a bank or stock exchange). Applications for distributed ledgers include cryptocurrencies, verification of supply chains such as for product provenance and emissions monitoring and verification, tracking recoverable and recyclable product content, land records, and share trading
