Chiliz Chain Changelog

Governance changes

The Chiliz Chain governance relies on a system of validators, with the Proof-of-Staked Authority (PoSA) consensus mechanism.

Since the Chiliz Chain’s inception, several decisions have been applied to it through the governance body.

Here is a selection of the most impactful ones, as of this writing:

• May 5th, 2023: Activate Proposers Registry

• May 17th, 2023: Decreasing Min. Stake Amount to 0.01CHZ

• October 24th, 2023: Disabling the Whitelist Mechanism

• March 13th, 2024: Fixing Validator Jailing issues

You can see the full list of decisions on the Chiliz Chain Governance page, including the addition of validators and previous whitelistings.

Blockchain evolution

Chiliz Chain is a fork of Binance’s BNB Smart 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.

August 2024: Chiliz Chain 2.2.3

• Fixed EffectiveGasPrice only containing Tip Fee.

July 2024: Chiliz Chain 2.2.2

• Fixed debug_trace* rpc json api methods

  • Updated the trace api method handlers to support tokenomics system transactions.

  • Updated stateAtTransaction method in eth state accessor to correctly handle the execution of tokenomics system transactions on "cold access".

  • Updated CaptureState method of prestate tracer to lookup account/contract address details before fetching slot details for SLOAD and SSTORE operations.

April 2024: Chiliz Chain 2.2.1

Implementation of several hard forks:

• Chiliz Chain "Dragon8" hard fork:

  • New Chiliz Chain tokenomics.

• BSC "Kepler" hard fork (from 2024/01/23):

  • BEP-319: Optimize the incentive mechanism of the Fast Finality feature

  • Includes part of Ethereum’s "Shanghai" Upgrade:

    • BEP-216: Implement EIP-3855 PUSH0 instruction

      • BEP-217: Implement EIP-3860 Limit and meter initcode

      • BEP-311: Warm COINBASE

      • BEP-312: Announce EIP-6049 Deprecate SELFDESTRUCT

• BSC "Hertz" hardfork, including "HertzFix" (from 2023/08/30):

  • Includes part of Ethereum’s "Berlin" Upgrade:

    • BEP-225: Implement EIP-2565 ModExp Gas Cost

    • BEP-229: Implement EIP-2718 Typed Transaction Envelope

    • BEP-230: Implement EIP-2929 Gas cost increases for state access opcodes

    • BEP-231: Implement EIP-2930: Optional access lists

  • Includes part of Ethereum’s "London" Upgrade:

    • BEP-227: Implement EIP-3198: BASEFEE opcode

    • BEP-226: Implement EIP-1559 with base fee of 2500

      • Of note: For Chiliz Chain’s implementation of EIP-1559, unlike BSC we set the initial base fee to 2500 gwei so that it behaves similarly to Ethereum. On BSC the base fee is 0.

    • BEP-228: Implement EIP-3541: Prevent deploying contracts starting with 0xEF

    • BEP-212: Implement EIP-3529: Reduction in Refunds

  • BSC "Planck" hard fork (from 2023/04/12):

    • BEP-171: Security Enhancement for Cross-Chain Module

    • BEP-172: Network Stability Enhancement On Slash Occur

  • BSC "Gibbs" hard fork (from 2022/12/12):

    • BEP-153: Introduce Native Staking on BSC

  • BSC "Moran" hard fork (from 2022/10/12):

    • Fix the exploiter attack (emergency, no BEP)

  • BSC "Nano" hard fork (from 2022/10/06):

    • Suspend CrossChain between BC & BSC due to the exploiter attack (emergency, no BEP)

Of note: We are still studying the enablement of the following hard forks: Luban, Plato, Euler. Their code is present in the Chiliz Chain codebase, but not yet enabled.

May 2023: Chiliz Chain 2.0.0 launch

• BSC "Bruno" hardfork (from 2021/11/30):

  • BEP-95: Real-Time Burning Mechanism

  • BEP-93: Diff Sync Protocol: Speed up node sync

• BSC "MirrorSync" hard fork (from 2021/02/25):

  • Upgrade 3 system contract (no BEP): TokenManagerContract, TokenHubContract, RelayerIncentivizeContract
