Technical Definition

Distributed Ledger

A distributed ledger is a shared database that is stored, synchronised, and maintained across multiple computers or participants rather than being controlled by one central database administrator. A blockchain is one type of distributed ledger.

Key Insight

Distributed-ledger technology, or DLT, is the broader technological concept behind many blockchain systems. Understanding the distinction matters because not every distributed ledger uses blocks, proof of work, public participation, or cryptocurrency. Banks, governments, and financial institutions may use distributed ledgers in systems that look very different from Bitcoin.

Common Misconceptions

Treating blockchain and distributed ledger as exact synonyms

Assuming every DLT is public

Assuming every distributed ledger uses cryptocurrency

Confusing decentralisation with distribution

Assuming permissioned networks work like Bitcoin

Ignoring governance structure

Detailed Explanation

How It Works

Multiple authorised or open network participants maintain copies of shared records.

A consensus or coordination mechanism determines which updates are valid.

Depending on the network, participants may be:

  • Public validators

  • Miners

  • Banks

  • Institutions

  • Approved consortium members

Blockchain systems organise data into linked blocks, while other distributed ledgers may use alternative structures.

FAQs

Is every blockchain a distributed ledger?
Generally yes.

Is every distributed ledger a blockchain?
No.

Can a distributed ledger be private?
Yes. Some systems allow only approved organisations to participate.

In Practice

Bitcoin uses a public blockchain where thousands of nodes can independently verify the ledger. A group of financial institutions could instead operate a permissioned distributed ledger where only approved members can validate transactions. Both are distributed ledgers, but their governance and access models are very different.
