Blockchain A – Z covers all of the important topics you need to know if you’re just getting into blockchain! We go letter by letter with each episode defining a specific topic. By the end of the series, you’ll know your blockchain ABCs!

What are Distributed Ledgers?

Distributed ledgers are a type of database that are spread across multiple sites, countries, or institutions. Records are stored one after the other in a continuous ledger.

A blockchain functions as a distributed ledger, and blockchain technology (BCT) is sometimes referred to as a distributed ledger technology (DLT).

Distributed ledger data can be either “permissioned” or “unpermissioned” to control who can view it. For example, unpermissioned, or decentralized, networks are employed in public blockchains like Bitcoin. On the other hand, JP Morgan’s Quorom and IBM‘s are permissioned ledgers – private and only accessible to certain parties.
