【Abstract】Blockchain technology is a revolution started as a new economy with an alternative currency namely Bitcoin. Besides the economical aspect, the technological capabilities of Blockchain such as distributed computing, record keeping, irrecoverability of transactions, reliability and etc., are harnessed by variety of real-world applications. Blockchain is a rising pool of records known as blocks linked using security procedure. It is typically managed by a group of nodes in a distributed network technology which integrates technologies such as distributed ledger, security and consensus algorithm to ensure reliability and immutability. In Blockchain, the access privileges are determined by a set of nodes called miners, which run the consensus algorithm to access and submit transactions in to the block after authentication. However, in the existing Blockchain, there is no mechanism to ensure the trust and robustness of the miners and eliminate the malicious miners which runs the consensus algorithm. Therefore, this paper proposes a trust model with an objective of eliminating untrusted nodes from the mining process to enhance the reliability and security of the Blockchain. Further, the proposed trust model is suitably analysed for transaction rate, efficiency and scalability with Hyper Ledger framework to ensure the robustness.

【摘要】区块链技术是一场革命，它以一种替代货币即比特币开始了新经济。除了经济方面，区块链的技术能力，如分布式计算、记录保存、交易的不可恢复性、可靠性等，被各种现实世界的应用所驾驭。区块链是一个不断上升的记录池，被称为区块，使用安全程序连接。它通常由分布式网络技术中的一组节点管理，整合了分布式账本、安全和共识算法等技术以确保可靠性和不变性。在区块链中，访问权限是由一组被称为矿工的节点决定的，这些节点运行共识算法，在认证后访问并提交交易到区块中。然而，在现有的区块链中，没有一个机制来确保矿工的信任和稳健性，并消除运行共识算法的恶意矿工。因此，本文提出了一个信任模型，目的是在采矿过程中消除不受信任的节点，以提高区块链的可靠性和安全性。此外，本文对所提出的信任模型的交易率、效率和可扩展性与超级账本框架进行了适当的分析，以确保其稳健性。
