# Architecture
|
|
|
|
Learn how Ethermint's architecture leverages the Cosmos SDK Proof-of-Stake functionality, EVM compatibility and fast-finality from Tendermint Core's BFT consensus. {synopsis}
|
|
|
|
## Cosmos SDK
|
|
|
|
Ethermint enables the full composability and modularity of the [Cosmos SDK](https://docs.cosmos.network/).
|
|
|
|
## Tendermint Core & the Application Blockchain Interface (ABCI)
|
|
|
|
Tendermint consists of two chief technical components: a blockchain consensus
|
|
engine and a generic application interface. The consensus engine, called
|
|
[Tendermint Core](https://docs.tendermint.com/), ensures that the same transactions are recorded on every machine
|
|
in the same order. The application interface, called the [Application Blockchain Interface (ABCI)](https://docs.tendermint.com/master/spec/abci/), enables the transactions to be processed in any programming
|
|
language.
|
|
|
|
Tendermint has evolved to be a general purpose blockchain consensus engine that
|
|
can host arbitrary application states. Since Tendermint can replicate arbitrary
|
|
applications, it can be used as a plug-and-play replacement for the consensus
|
|
engines of other blockchains. Ethermint is such an example of an ABCI application
|
|
replacing Ethereum's PoW via Tendermint's consensus engine.
|
|
|
|
Another example of a cryptocurrency application built on Tendermint is the Cosmos
|
|
network. Tendermint is able to decompose the blockchain design by offering a very
|
|
simple API (ie. the ABCI) between the application process and consensus process.
|
|
|
|
## EVM module
|
|
|
|
Ethermint enables EVM compatibility by implementing various components that together support all the EVM state transitions while ensuring the same developer experience as Ethereum:
|
|
|
|
- Ethereum transaction format as a Cosmos SDK `Tx` and `Msg` interface
|
|
- Ethereum's `secp256k1` curve for the Cosmos Keyring
|
|
- `StateDB` interface for state updates and queries
|
|
- JSON-RPC client for interacting with the EVM
