Distributed network of Proof of Reputation consensus protocol

Background:

Current status of blockchain technology: Although blockchain technology has made progress, it still faces challenges such as scalability, system security and decentralization, file storage, low transaction fees, and smart contract iteration.

Technical bottleneck: Existing blockchain systems are difficult to handle high-frequency micro-transactions and large-scale commercial application needs, with high transaction costs, and concentrated computing power leads to monopoly by a few users.

Invention content:

Solution: A distributed network and ecosystem based on an innovative Proof of Reputation consensus protocol is proposed to solve the above technical bottlenecks.

System structure: The system consists of an application layer, a virtual machine, an incentive layer, a consensus layer, a network layer, and a data layer, and uses a DAG data structure to maintain the positive scalability of the system.

Core innovation: Through the POR (Proof of Reputation) Proof of Reputation consensus protocol, a decentralized reputation system and incentive system are realized to promote active user participation and healthy development of the system.

Technical solution:

Application layer: Supports light nodes/full nodes, smart contract modification, zero-knowledge verification, side chain support, distributed storage and computing power platform.

Virtual machine: provides a universal interface to convert application layer software into underlying commands, adopts BVM virtual machine, and supports multi-language development.

Incentive layer: responsible for reputation rewards and decentralized distribution mechanism, accounting nodes are rewarded through accounting.

Consensus layer: determines accounting nodes through POR reputation proof and payment channel, verifies transactions and adjusts reputation values.

Network layer: responsible for the transmission of underlying data and commands, including P2P communication, relay network and verification mechanism.

Data layer: adopts DAG data structure, quantum hash function, distributed hash table, Merkle Tree and account system and other technologies to ensure data security and efficient processing.

Specific implementation method:

Node classification: system nodes are divided into user nodes and accounting nodes. User nodes use system functions, and accounting nodes are responsible for system maintenance.

Reputation value calculation: Reputation value is constructed from three dimensions: social activity, time activity and contribution activity, and decays over time.

Consensus process: define a list of honest nodes, verify transactions through the Byzantine fault tolerance process, dynamically screen trusted nodes, and distribute rewards based on contributions.

Technical details: The specific application and implementation methods of technologies such as DAG data structure, quantum encryption algorithm, Merkle Tree, etc. are introduced in detail.

System advantages:

High throughput and high concurrency: Support high-frequency micro-transactions to meet the needs of large-scale commercial applications.

Low transaction costs: Keep low fees or even free transactions through reputation incentive mechanisms.

Decentralization and decentralization: Ensure extensive user participation and avoid concentration of computing power through POR consensus protocol and incentive system.

Technological innovation: Introduce advanced technologies such as quantum encryption algorithm and distributed hash table to improve system security and data processing capabilities.

Commercial application prospects:

Ecosystem construction: Support smart contract iteration, side chain development, etc., and provide developers with rich tools and templates.

Sustainable development: Continuously replenish the reward pool through the income in the business ecosystem, maintain the enthusiasm of node participation, and promote the healthy development of the ecosystem.

What is the core purpose?

A: Solve the technical bottlenecks of blockchain technology in large-scale commercial applications, such as scalability, system security and decentralization, file storage, low transaction fees, and smart contract iteration. By proposing a distributed network and ecosystem based on an innovative reputation proof consensus protocol, the sustainable development of high-frequency micro-transactions and social applications can be achieved.

What layers does the system consist of?

A: The system consists of six layers: application layer, virtual machine, incentive layer, consensus layer, network layer, and data layer.

What is the POR consensus protocol?

A: The POR (Proof of Reputation) consensus protocol is a consensus mechanism based on reputation proof. It determines the accounting node through the reputation value of the node, verifies the transaction and adjusts the reputation value, thereby ensuring the decentralization and dispersion of the system.

How to calculate the reputation value of the node?

A: The reputation value of the node is constructed from three dimensions: social activity, time activity, and contribution activity, and decays over time. The specific calculation formula takes into account factors such as the number of transactions, transaction amount, currency age of the token held, and contribution to the system.

How does the system solve the file storage problem in the blockchain?

Answer: The system uses distributed hash table technology to store large files on the blockchain by breaking up a large file and storing it on each node of the network.

What is the role of the DAG data structure in the system?

Answer: The DAG (directed acyclic graph) data structure is used in the system to model transaction behaviors on the distributed accounting network, maintain the positive scalability of the system, and quickly support data search, modification, deletion and establishment.

How does the system ensure the security of data?

Answer: The system uses quantum hash functions with quantum-level attack resistance to encrypt and verify data, and uses Merkle Tree tree data structure to verify the content of large data structures to ensure data security and integrity.

What are integrity nodes and mutual trust nodes?

Answer: Integrity nodes are high-reputation nodes selected by reputation value, responsible for system maintenance and transaction verification. Mutual trust nodes refer to two nodes that have reached a consensus of mutual trust in some way, including friend-and-family mutual trust nodes and high-reputation mutual trust nodes, which are suitable for high-frequency offline transactions.

How does the system motivate users to participate?

Answer: The system encourages user participation through reputation rewards and decentralized distribution mechanisms. Accounting nodes obtain system rewards through accounting, and the computing power contributed by the nodes is also rewarded with corresponding reputation value through program settings.

What is the commercial application prospect of this invention?

Answer: It has broad commercial application prospects, supports high-frequency micro-transactions and large-scale commercial applications, provides rich tools and templates such as smart contract iteration and side chain development, maintains the enthusiasm of nodes through sustainable reward pools, and promotes the healthy development of the ecosystem
