Popular Science in the Currency Circle: An article introducing what the protocol ledger means

Article summary: A protocol ledger is a distributed database used to record and verify transactions, playing a vital role in blockchain and other distributed systems. It allows participants to collaborate in a secure and transparent environment, ensuring transactions are trustworthy and immutable.

Protocol Ledger: A simple explanation

What is a protocol ledger?

A protocol ledger is a distributed ledger maintained by multiple unrelated participants that can be used to record and verify transactions. Unlike traditional centralized databases, the data on the protocol ledger is secure, transparent, and cannot be controlled by any single entity.

How the protocol ledger works

• Distributed architecture: The protocol ledger is stored on computers distributed across multiple nodes In the network, each computer maintains a copy of the ledger.
• Consensus mechanism: When new transactions enter the network, nodes use a consensus mechanism (such as proof of work or proof of stake) to reach consensus and determine which transactions are valid.
• Immutability: Once a transaction is verified and recorded in the ledger, it becomes immutable. This means transactions cannot be forged, altered or deleted.

Types of protocol ledgers

• Public protocol ledger: Open to everyone, anyone can Participate in validating and recording transactions. The most well-known public protocol ledgers are Bitcoin and Ethereum.
• Federation Protocol Ledger: is maintained and controlled by a group of known and trusted entities. Ideal for use cases requiring higher levels of privacy and regulation.
• Private Protocol Ledger: Completely controlled by a single entity, allowing only authorized parties to participate in validating and recording transactions.

Use cases for protocol ledgers

Protocol ledgers are widely used in a variety of industries, including:

• Finance: Cryptocurrency trading, cross-border payments, supply chain management
• Healthcare: Medical record management, clinical trial tracking
• Government:Digital Voting, Land Registration, Identity Verification

Advantages of Protocol Ledger

• Secure and Immutable: The distributed architecture and consensus mechanism ensure data security and accuracy.
• Transparent and Auditable: All transactions are recorded in the ledger and can be verified by anyone.
• Efficiency and Automation: Protocol Ledger automates processes, reducing errors and costs.
• Trust Minimization: The protocol ledger reduces the need for trust by eliminating dependence on a single entity.
