An enhanced consensus algorithm for blockchain.

Area of Science:

• Blockchain Technology
• Distributed Systems
• Cryptography

Background:

• Delegated Proof of Stake (DPoS) is widely used in public and hybrid blockchains.
• Current DPoS systems suffer from low voter engagement and security vulnerabilities from malicious nodes.

Purpose of the Study:

• To introduce the Deep Link-Delegated Proof of Stake (DL-DPoS) consensus mechanism.
• To address low node participation and enhance security in DPoS systems.

Main Methods:

• Implemented the LINK incentive mechanism to boost voting participation.
• Introduced a credit scoring system (wealth, performance, stability) for node security.
• Optimized the verification process and introduced mechanisms against malicious nodes.

Main Results:

• DL-DPoS demonstrated a 23% increase in throughput compared to DPoS.
• Achieved over 95% node participation in voting and leader selection.
• Showcased improved distribution of rights and equity, enhancing network stability.

Conclusions:

• DL-DPoS significantly enhances blockchain consensus performance, security, and stability.
• The LINK incentive and credit scoring systems effectively address DPoS limitations.
• DL-DPoS offers a more robust and efficient consensus mechanism for blockchain applications.
