Blockchain Consensus Mechanism Study Guide

Glossary

Term DefinitionNode (Node) refers to any general-purpose computer that registers and becomes part of the blockchain ecosystem, associated with the blockchain platform. Nodes can register themselves (if they are part of a public chain) or be invited to join (if they are part of a permissioned chain). Candidate nodes (Candidate) Nodes that make up the committee. Candidate nodes are selected based on their geographical distribution, geographical density, related crypto assets, and reputation scores. Leader nodes (Leader) Nodes automatically selected by software logic, generated by a cryptographic lottery mechanism or random selection. Leader nodes are responsible for submitting blocks to the blockchain. Crypto-asset (Crypto-asset) The relevant tokens pledged by users/nodes in the blockchain system are a variable in the weighted scheme for leader node election. Reputation score (Reputation Score) The score established by a node over a period of time, based on multiple factors, including node uptime, number of blocks verified, number of node lists, number of nodes in the blacklist, and crypto asset holding time.

Short answer questions

Please briefly describe the core idea of ​​the blockchain consensus mechanism proposed in this patent?

The patent proposes a blockchain consensus mechanism called "Proof-Of-DIGEST". The core idea is to combine factors such as the geographical distribution, geographical density, crypto asset holdings and reputation scores of nodes, select candidate nodes to form a committee through weighted calculation, and randomly select leader nodes to verify and confirm block transactions, and finally achieve efficient, secure and decentralized blockchain consensus.

What role does the "smart hardware" mentioned in the patent play in the blockchain system?

Smart hardware is mainly responsible for monitoring the health of blockchain infrastructure in this system, and has functions such as automatic diagnosis, automatic repair and threat monitoring. It works with the data bus and consensus algorithm to ensure that all participants on the platform operate in a coordinated, consistent and non-destructive manner.

How is the "reputation score" calculated in this consensus mechanism?

The calculation of the reputation score is based on multiple factors of the node, including node uptime, number of verified blocks, number of node lists, number of nodes in the blacklist, and crypto asset holding time. The system weights each factor according to platform requirements and use cases and allows administrators to adjust it.

How does this consensus mechanism select candidate nodes to form a committee?

The system will perform weighted calculations based on data such as the node's geographic location, geographic density, crypto asset holdings, and reputation score. Nodes with higher scores will be selected as candidate nodes to form a committee.

How does this consensus mechanism select leader nodes?

In the committee composed of candidate nodes, the system will use encrypted random numbers to select leader nodes to ensure fairness and justice.

What role does "crypto assets" play in the election of leader nodes?

Crypto assets are a variable in the weighted scheme for leader node elections. The more crypto assets a node holds, the higher its weight in the election.

How does this consensus mechanism incentivize the positive behavior of nodes?

The mechanism will reward additional tokens to validators or nodes with higher reputation scores, thereby incentivizing nodes to actively participate in the maintenance and development of the blockchain.

What are the advantages of this consensus mechanism?

This consensus mechanism has the advantages of high efficiency, security, and decentralization, which can effectively improve the transaction throughput of the blockchain while ensuring the security and stability of the system.

What innovations does this consensus mechanism have compared to traditional consensus mechanisms?

This consensus mechanism innovatively takes into account factors such as geographic location, geographic density, crypto asset holdings and reputation scores, and adopts weighted calculation and encrypted random numbers to select nodes, realizing a more flexible, efficient and secure consensus mechanism.

What is the application prospect of this consensus mechanism?

This consensus mechanism can be applied to a variety of blockchain protocols to build a fast, efficient and secure next-generation blockchain platform, which has broad application prospects.
