What is a Distributed Ledger in Blockchain?

1. Definition: A distributed ledger is a shared, immutable digital record of transactions that is maintained across multiple computers in a decentralized network.

2. Core Features:

   • Decentralization: No single entity controls the ledger, eliminating central points of failure and censorship.
   • Immutability: Once transactions are recorded on the ledger, they cannot be altered or deleted, ensuring data integrity.
   • Transparency: All participants in the network can view the entire ledger and verify transactions.

3. Working Mechanism:

   • Transactions are broadcast to all nodes in the network.
   • Nodes validate the transactions based on pre-defined protocols.
   • Once a consensus is reached, the transactions are added to the ledger.
   • Each node maintains a copy of the complete ledger, ensuring data redundancy.

4. Benefits:

   • Increased Security: Decentralization and immutability make it difficult for unauthorized parties to tamper with the ledger.
   • Trustless System: Eliminates the need for intermediaries or trusted third parties by relying on the collective trust of the network.
   • Transparency and Auditability: Provides a complete and verifiable record of all transactions for enhanced transparency and accountability.
   • Cost Reduction: Reduces the costs associated with maintaining paper records and third-party verification.

5. Applications:

   • Cryptocurrency transactions (e.g., Bitcoin, Ethereum)
   • Digital asset management
   • Supply chain management
   • Voting systems
   • Auditing and compliance
   • Healthcare recordkeeping
