摘要:
区块链技术作为数字货币的基础,实现了去中心化环境下的信任建立与价值传递。 随着区块链技术在众多应用领域的深入,区块链所承载的数字资产呈现多元化、复杂化,? ? 信息数量的急速增长对区块链的性能提出了更高的要求。 采用多链、跨链等技术的主从多链模型,缓解了传统单链模型的性能瓶颈,但现有的共识机制无法适用于主从多链。 为此提出一种包含个体共识机制与元共识机制的集成共识机制,确保主从多链模型的区块安全性验证。 利用并行的多种共识机制作为个体共识机制, 保证了主链在处理从链交易时的高效性。 主链中的元共识机制对个体共识的结果进行验证,提高了主链区块的安全性。 多种安全性分析与实验结果表明,提出的针对主从多链的集成共识机制较传统的共识机制具备较高的性能与安全性,保证了不同区块链网络节点间自由、安全、有效的数据转换。
Abstract:
As the foundation of digital currency,blockchain technology realizes the establishment of trust and the delivery of value in decentralized environment. With the development of blockchain technology in many application areas, the digital assets carried by blockchain are diversified and complicated,and the rapid growth of the amount of information proposes higher requirements for the performance of blockchain. The emergence of master and slave multi-chain model with multi-chain and cross-chain technologies alleviates the performance bottleneck of the traditional single-chain model,but the existing consensus mechanism cannot be applied to master and slave multi - chain. Therefore, an integrated consensus mechanism including individual consensus mechanism and meta - consensus mechanism is proposed to ensure security verification of blocks in master and slave multi-chain model. Multiple concurrent consensus mechanisms are used as individual consensus mechanisms to ensure the high efficiency of master chain in dealing with the transactions in slave chains. The meta-consensus mechanism in the master chain verifies individual consensus results and improves the security of the master chain block. Various security analysis and experimental results show that the proposed integrated consensus mechanism for master and slave multi-chain has higher performance and security than the traditional consensus mechanism,which ensures the free,secure andeffective data exchange between different blockchain nodes.
