Tech stack & purpose

Cronos is an EVM-compatible blockchain network built on the Cosmos SDK, combining Ethermint for EVM execution, CometBFT for consensus, and IBC for interoperability. The project addresses scaling challenges in DeFi, GameFi, and Web3 by enabling developers to port applications and assets from other chains while benefiting from low fees, high throughput, and fast finality. Written in Go, Cronos uses a custom architecture centered on the `x/cronos` module for token mapping and EVM integration, along with optimized store backends (memiavl and versiondb) for performance, and is maintained by Crypto.org Chain via forked versions of the Cosmos SDK, Ethermint, and CometBFT pinned in its module dependencies.
