# EVM Execution

> Recommended versions and genesis files for mainnet and Bepolia.

Berachain is 100% EVM-compatible, operating on a lightly modified Reth. We keep pace with Ethereum improvements, shipping [Protocol Upgrades](/build/protocol/overview) every 6 months.

Recommended [**Beacon Kit**](https://github.com/berachain/beacon-kit) and [**Bera-Reth**](https://github.com/berachain/bera-reth) versions depend on the network:

| Network | Beacon Kit                                                                      | Bera-Reth                                                            |
| ------- | ------------------------------------------------------------------------------- | -------------------------------------------------------------------- |
| Mainnet | [v1.4.1](https://github.com/berachain/beacon-kit/releases/tag/v1.4.1)           | [v1.4.4](https://github.com/berachain/bera-reth/releases/tag/v1.4.4) |
| Bepolia | [v1.4.2-rc.0](https://github.com/berachain/beacon-kit/releases/tag/v1.4.2-rc.0) | [v1.4.4](https://github.com/berachain/bera-reth/releases/tag/v1.4.4) |

**New with Beacon Kit v1.4.1 & greater:** Use the option `--chain (bepolia|mainnet)` instead of `--chain <path>`. You can continue to specify the genesis file path, but be sure to verify its hash:

| Genesis File | Updated       | Download link & md5 hash                                                                                                                                                    |
