Learn about Ethermint and its primary features.

# What is Ethermint

Ethermint is a scalable, high-throughput Proof-of-Stake blockchain that is fully compatible and interoperable with Ethereum. It's built using the Cosmos SDK which runs on top of Tendermint Core consensus engine.

Ethermint allows for running vanilla Ethereum as a Cosmos application-specific blockchain. This allows developers to have all the desired features of Ethereum, while at the same time, benefit from Tendermint’s PoS implementation. Also, because it is built on top of the Cosmos SDK, it will be able to exchange value with the rest of the Cosmos Ecosystem through the Inter Blockchain Communication Protocol (IBC).

# Features

Here’s a glance at some of the key features of Ethermint:

Ethermint enables these key features by:

  • Implementing Tendermint Core's Application Blockchain Interface (ABCI) to manage the blockchain
  • Leveraging modules and other mechanisms implemented by the Cosmos SDK.
  • Utilizing geth as a library to avoid code reuse and improve maintainability.
  • Exposing a fully compatible Web3 JSON-RPC layer for interacting with existing Ethereum clients and tooling (Metamask, Remix, Truffle, etc).

The sum of these features allows developers to leverage existing Ethereum ecosystem tooling and software to seamlessly deploy smart contracts which interact with the rest of the Cosmos ecosystem!
