# 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:

**New with 1.4.1:** 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                                                                                                                       |
