N2 - The surprising wave of blockchain has led to rapid progress of Byzantine fault tolerant protocol. However, most researches concentrate on the centralized trust such as PBFT, in which all participants trust each other equally. This paper presents DWBFT, a weighted Byzantine fault tolerant protocol with decentralized trust under the weak synchrony assumption. In DWBFT, the nodes can assign weights to each other depending on their decentralized trust relationship, which are adopted to make decisions. DWBFT can achieve safety under the condition that the weight of Byzantine nodes is less than 1/5 of the total weight of all nodes under any weight assignment. The experimental results show that DWBFT can achieve a throughput of nearly 13,000 tps under 32 nodes, and has no significant performance degradation compared with PBFT.
