Cosmos aims to be a "blockchain internet" that will solve these problems once and for all. The architecture of Cosmos consists of several independent blockchains, called "zones", attached to a central blockchain called "Hub".
According to the Cosmos white paper, "These areas are supported by Tendermint Core, which provides a high-performance, consistent, and secure PBFT consensus engine, in which a strict fork-accountability guarantee can control the behavior of malicious actors. Tendermint Core's BFT consistency The algorithm is very suitable for extending the public equity proof blockchain."
Behind the project are CEO Jae Kwon, CTO Ethan Buchman and the Interchain Foundation team.
What is Tendermint?
Tendermint is a variant of PBFT, that is, actual Byzantine fault tolerance. The Byzantine Fault Tolerance (BFT) system is a system that successfully addresses the Byzantine Generals problem. We have detailed the issue of the Byzantine generals here. To keep it short, in order for the decentralized peer-to-peer system to operate in a trustless manner, they must find a solution to the Byzantine Generals problem.
As stated in the cosmos white paper:
"Tendermint provides excellent performance. In a benchmark test of 64 nodes in 7 data centers on 5 continents, on commodity cloud instances, Tendermint consensus can process thousands of transactions per second, with a submission delay of approximately 1 to 2 Seconds. It’s worth noting that even under severe stress test conditions, the performance of a thousand transactions per second remains the same."
