Distributed Ledgers
Shared state.
What Is a Distributed Ledger?
A distributed ledger is a database that is replicated and synchronized across many independent computers called nodes.
There is no single master copy — every node holds the full ledger and helps keep it consistent.
Centralized vs Distributed
A traditional ledger lives on one server controlled by one party. A distributed ledger removes that single point of control and failure.
- Centralized: one owner, one copy, one trust anchor
- Distributed: many peers, many copies, shared trust
