Attention

  • SELFDESTRUCT will no longer be refunded
  • There are 3 hard forks, node operators need to set them up at the same fork height, i.e. BerlinBlock = 31103030, LondonBlock = 31103030, HertzBlock = 31103030

Description

v1.2.7 is a hard-fork release for BSC testnet.

The testnet is expected to have 3 scheduled hardfork upgrades named Hertz, London, Berlin) at same block height 31,103,030. The current block generation speed forecasts this to occur around 29th Jun 2023.
The validators and full node operators on testnet should switch their software version to v1.2.7 before 29th Jun 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
