# Blockchain code changes Chiliz Chain is a fork of Binance’s BNB Smart Chain ([BSC](https://github.com/bnb-chain/bsc)), which is itself a fork of Ethereum. The Chiliz Chain team pays close attention to the evolution of both Ethereum and BSC in order to include the important changes that they receive. Here are all the changes that we merged into the Chiliz Chain codebase so far, from latest to oldest. ## September 2025: Chiliz Chain 2.6.0 — SNAKE8 Hard Fork The SNAKE8 hard fork introduces an improved Validator Reward Distribution logic.

Key updates include: * Consensus (Parlia) enhancements: \ Improved snapshot recovery, support for consecutive block production, and adjusted mining/backoff times. * Hard fork & network upgrades: \ Introduced Bohr hard fork for Testnet, Tycho (Cancun) upgrades for Mainnet, and other scheduled network transitions. * Performance & pruning: \ Optimized state pruning (including `prunefreezer` fixes), enhanced multi-database support, and improved chain commit performance. * MEV & bidding Improvements: \ Added rate limiting, enhanced bidding logs, and integrated new MEV parameters/functions. * Tooling & testing:\ New developer tools and flags for controlling block intervals, additional logging/metrics (including blob transaction support), and stability fixes in tests.
