This is a summary of this paper.

This paper developed multi-metric evaluation framework for Pipelined Hotstuff performance with respect to its growth rate, chain quality, and latency. Then, the paper compares the pipelined hotstuff performance with libraBFT performance.

The pipelined hotstuff and libraBFT algorithms are the same with some difference…

This post is a summary of RingBFT paper.

There are two types of sharding systems in Blockchain that are based on the behavior of transactions called single-shard and cross-shard. Single-shard means the request will modify the state of only replicas in a single shard (a group of replicas in the…

Chain Replication (CR) is a protocol that handles crash failure for replicated storage object on a large scale system for high throughput, high availability, and strong consistency. This storage object is called storage services.

Storage services provides a client view of the object that has two states called history (Hist_objID)…

In this post, I summarized the Fast-HotStuff paper. This paper published by Mohammad Jalalzai from The University of British Columbia, Jianyu Niu, and Chen Feng.

The Fast-Hotstuff (FHS) is a new consensus algorithm for blockchain. It has the same properties that were proposed in HotStuff: linear view change complexity and…
