In the web3 world, blockchain is often described as a decentralized digital ledger. But what exactly is a ledger in the context of blockchain? It’s essentially a revolutionary record-keeping system.

Key Features of a Blockchain Ledger
- Decentralized: Not controlled by a central authority.
- Digital: All records are stored electronically.
- Immutable: Once a transaction is recorded, it cannot be altered.
- Distributed: The ledger is copied across many computers.
- Transparent: Transaction details are publicly viewable.
How Blockchain Ledgers Work
Blockchains organize transactions into “blocks.” These blocks are linked together chronologically, forming a “chain.” Each block contains:
- A set of transactions
- A timestamp
- A unique hash (identifier)
This structure ensures data integrity and prevents tampering.
Benefits of Blockchain Ledgers
- Security: Cryptography protects transactions.
- Transparency: Increases trust and accountability.
- Efficiency: Streamlines processes by removing intermediaries.
- Immutability: Ensures data integrity and reliability.
In essence, the ledger in blockchain is a digitized, decentralized, public record that maintains account information by referencing its origin, fostering transparency and security in digital asset ownership.
