1. Project introduction

Evmos 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.

Evmos 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).

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

(1) Web3 and EVM compatibility

(2) High throughput via Tendermint Core(opens new window)

(3) Horizontal scalability via IBC(opens new window)

(4) Fast transaction finality

Evmos enables these key features by:

(1) Implementing Tendermint Core's Application Blockchain Interface (ABCI) to manage the blockchain

(2) Leveraging modules and other mechanisms implemented by the Cosmos SDK.

(3) Utilizing geth as a library to promote code reuse and improve maintainability.

(4) Exposing a fully compatible Web3 JSON-RPC layer for interacting with existing Ethereum clients and tooling (Metamask, Remix, Truffle, etc).

2. Application

The denomination used for staking, governance and gas consumption on the Evmos is the EVMOS. The EVMOS provides the utility of:

(1) Securing the Proof-of-Stake chain;

(2) Token used for governance proposals;

(3) Fee distribution;

(4) As a mean of gas for running smart contracts on the EVM.
