Network protocol for tamper-proof data

Network protocol for tamper-proof data

Consensus mechanism improvement:

PoW (proof of work) and committee election: Nodes compete to become committee members by generating random strings and executing the PoW process. Nodes that successfully complete PoW are elected as sub-committee members and update the sampling graph. This process is repeated until the leadership committee is determined.

Sharding strategy: The leadership committee is responsible for dividing the nodes in the network into multiple sharding committees. Each sharding committee manages a shard of the blockchain to achieve parallel processing and storage and improve system throughput.

Network architecture and node functions:

System composition: The system consists of multiple nodes, each with a unique identifier, and nodes transmit messages through a secure communication protocol.

Node module: The node contains a processor, a memory device, a network interface, and a computer-readable medium, the latter of which contains code modules that perform functions such as consensus, election, and reconfiguration.

Dynamicity and security:

New node joining: The new node requests to join the network by executing the PoW process and submitting a solution to the existing committee. After the committee verifies the solution, it allows the new node to replace the existing node and notify other nodes in the network.

Byzantine fault tolerance: The protocol can tolerate up to a certain proportion of Byzantine nodes (i.e. malicious nodes), ensuring the stable operation of the system under high node failure rates.

Performance improvement:

Reduced communication overhead: Sharding reduces the amount of information that each node needs to exchange. Each node only needs to communicate with nodes within the shard, reducing the use of network bandwidth.

Reduced latency: Through parallel processing and shard storage, the system can increase transaction processing speed without increasing the communication burden on nodes, thereby reducing transaction latency.

Experimental results and evaluation:

Relationship between the number of communication messages and the number of nodes: Experimental results show that compared with existing solutions, this method significantly reduces the number of messages exchanged between nodes, especially when the number of nodes increases.

Relationship between transaction processing cost and number of nodes: This method can process more transactions while maintaining a low processing cost, improving the scalability of the system.

Application scenarios:

Asset transfer network: This method is suitable for any network that needs to efficiently and securely process large amounts of asset transfers, such as blockchain networks, payment processing systems, etc.

This document proposes a new consensus mechanism and sharding strategy to address the challenges of existing blockchain technology in terms of throughput, latency, and scalability, and provides new ideas for building efficient and secure distributed systems.

Summary of short answer questions:

What is the core technology of the application?

Answer: The core technology of the application is an improved consensus mechanism and sharding strategy to improve the verification speed and tamper-proof ability of the blockchain network. Specifically, it includes the election of committee members through proof of work (PoW), and the leadership committee is responsible for sharding the blockchain data.

How do nodes join the network?

Answer: New nodes request to join the network by executing the PoW process and submitting solutions to the existing committee. After the committee verifies the solution, the new node is allowed to replace the existing node and notify other nodes in the network.

What is the purpose of the sharding strategy?

Answer: The purpose of the sharding strategy is to divide the nodes and data in the blockchain network into multiple smaller shards, each of which is managed by a sharding committee. This enables parallel processing and storage, improving the throughput and scalability of the system.

How does this method reduce communication overhead?

Answer: This method reduces the amount of information that each node needs to exchange through sharding. Each node only needs to communicate with nodes within the shard, rather than with every node in the entire network, significantly reducing the use of network bandwidth.

What are the main advantages of this method compared to traditional blockchain technology?

Answer: Compared with traditional blockchain technology, the main advantages of this method include higher throughput, lower latency, and better scalability. Through sharding and parallel consensus mechanisms, this method can significantly improve the performance of blockchain networks.

What is the role of Byzantine fault tolerance in this method?

Answer: Byzantine fault tolerance ensures that the system can tolerate a certain proportion of malicious nodes (i.e., Byzantine nodes) in this method. This means that even if some nodes fail or are attacked, the system can still operate stably and reach consensus.

How do the experimental results prove the effectiveness of this method?

Answer: The experimental results prove the effectiveness of this method in reducing communication overhead, increasing transaction processing speed, and maintaining low processing costs by comparing indicators such as the number of communication messages and transaction processing costs under different numbers of nodes. Experimental data shows that this method is significantly better than existing solutions
