Ledger
Table of contents
A ledger is a digital or physical record-keeping system that tracks transactions or data entries. In blockchain, it refers to a decentralized database that logs all transactions across a network, ensuring transparency and immutability.
The Role of Ledgers in Crypto
Blockchain ledgers are distributed across nodes, with each participant maintaining a copy. These ledgers store every transaction ever made on the network, validated through consensus mechanisms to prevent tampering or double-spending.
Why It Matters
Ledgers are foundational to the trustless nature of blockchain technology, providing a verifiable and permanent record without relying on a central authority.
