1. What Is a Distributed Ledger
A distributed ledger is a database that is shared, replicated, and synchronized across multiple participants, with no single party controlling the whole system. Blockchain is one type of distributed ledger.
2. How It Works
Each participant (node) keeps a copy of the ledger and reaches agreement on updates through a consensus protocol. Changes are recorded in an append-only structure — in blockchains, linked blocks — making history tamper-evident. Permissioned ledgers restrict who can participate; permissionless ledgers (like Bitcoin) allow anyone.
3. Why It Matters
Distributed ledgers remove the need for a central authority to coordinate records, enabling trustless coordination across untrusted parties. They are the substrate of cryptocurrencies, supply-chain tracking, and settlement systems, and they define the trade-offs (performance, privacy, governance) of every Web3 network.
4. Key Facts
- Blockchain is a chain of blocks; DAGs are another distributed-ledger form
- Permissioned ledgers (e.g., Hyperledger, Corda) target enterprises
- Consensus is the core mechanism distinguishing designs
- Immutability is a design property, not absolute
