Distributed Ledger Technology

What is Distributed Ledger Technology?

Distributed Ledger Technology (DLT) is a digital system for recording the transaction of assets in which the transactions and their details are recorded in multiple places at the same time. Unlike traditional databases, distributed ledgers have no central data store or administration functionality.

Key Aspects

1. Decentralization: No single point of control or failure.

2. Transparency: All participants can view the ledger.

3. Immutability: Once recorded, data is difficult to alter.

4. Consensus: Agreement on the state of the ledger is reached through various mechanisms.

5. Efficiency: Can reduce operational complexities and costs.

How DLT Works

1. Transaction Initiation: A participant initiates a transaction.

2. Verification: The transaction is verified by the network.

3. Consensus: The network agrees on the validity of the transaction.

4. Recording: The transaction is recorded across all nodes.

5. Execution: The transaction is completed.

Types of DLT

1. Public: Open to anyone to participate.

2. Private: Restricted to specific participants.

3. Permissioned: Participants need permission to perform certain actions.

4. Permissionless: Anyone can perform actions on the network.

DLT vs. Traditional Databases

1. Centralization: Traditional databases are centralized, DLT is decentralized.

2. Control: DLT is not controlled by a single entity.

3. Data Storage: DLT stores data across multiple nodes.

4. Transparency: DLT offers greater transparency to all participants.

5. Immutability: DLT provides stronger resistance to data manipulation.

Use Cases

1. Financial Services: Cross-border payments, trade finance.

2. Supply Chain Management: Tracking goods from production to delivery.

3. Healthcare: Secure sharing of patient records.

4. Government: Land registries, voting systems.

5. Identity Management: Decentralized identity verification.
