Description

It is a hard-fork release for BSC mainnet.
It sets up the hard fork height for both Plato and Hertz(Berlin,London).
The two hard forks have been running on Testnet for a while and their hard fork height are close, so we decide to put them within a single release to save the upgrade effort.
For the detail changes of the two hard fork, pls refer: https://forum.bnbchain.org/t/bnb-chain-upgrades-mainnet/936

The validators and full node operators on mainnet should switch their software version to v1.2.9 before Aug-10th-2023.

Plato

The mainnet is expected to have a scheduled hardfork upgrade named Plato at block height 30,720,096. The current block generation speed forecasts this to occur around Aug-10th-2023.
The Plato hardfork includes 1 BEPs:

Hertz

The mainnet is expected to have 3 scheduled hardfork upgrades named (Hertz, London, Berlin) at same block height 31,302,048. The current block generation speed forecasts this to occur around Aug-30th-2023.

The Hertz hardfork will port some of London&Berlin upgrades from Ethereum to BSC for compatiblity. But due to the difference between the 2 networks, there would inevitably has difference in implementation, especially the difference in EIP-1559, the BaseFee will be zero on BSC, so this hard fork will neither introduce new burn mechanism nor the concept of GasTip. In short words, it only provides the interface, but actually no change to the current BSC Gas mechanism.

Here is the list of Hertz upgrade:

There are many changes with these BEPs, DApp developers & users needs to make sure they clearly understand these changes and the potential impact to their business.

  • New transaction types are supported, i.e. AccessList & DynamicFee(1559), by BEP-229, BEP-231, BEP-226
  • The gas metering mechanism has been changed, by BEP-225, BEP-230, BEP-212;
  • New EVM opcode(BASEFEE) is supported, by BEP-227
  • Prevent deploying contracts starting with 0xEF, by BEP-228
