Architecture

Overview

The Cronos blockchain protocol is an open-source project based on:

  • Ethermint, an open-source Cosmos application module that allows the portability of the Ethereum Virtual Machine (EVM), its go-ethereum client, and its solidity-based smart contracts to the Cosmos ecosystem.

  • Cosmos SDK, the leading development framework to build interoperable sovereign blockchains.

  • Tendermint’s Core BFT Proof-of-Stake consensus engine, a scalable and energy-efficient blockchain consensus.

The open-source Cronos blockchain protocol is fast, cheap, and energy-efficient.

Going forward, Cronos aims to leverage the best of what the Ethereum/EVM and Cosmos ecosystems both have to offer for end-users and developers.

Open-source project

Consensus

The Cronos consensus is commonly referred to as a proof-of-authority (POA) consensus, as it is a permissioned variant of the proof-of-stake consensus.

Please refer to the Cronos repository for details.

Tendermint was selected by Cronos as the underlying technology for several reasons:

  • Backed by formal research

  • Robustly tested implementation

  • Strong track record: Tendermint has been in continuous development since 2014, and has been adopted by several high-profile projects

  • Modular architecture: It offers flexibility regarding which applications are developed on top of it, and how they are developed.
