Description

Release v1.4.5 is a hard fork release for BSC Chapel Testnet, the HF name is: Tycho, it mainly support Cancun EIPs on BSC:

• a.BEP-336: Implement EIP-4844: ProtoDanksharding
• b.BEP-343: Implement EIP-1153: Transient storage opcodes
• c.BEP-344: Implement EIP-6780: SELFDESTRUCT only in same transaction
• d.BEP-342: Implement EIP-5656: MCOPY
• e.BEP-345: Implement EIP-7516: BLOBBASEFEE opcode

But BSC won’t support “EIP-4788: BeaconRoot”, as there is no CL on BSC.

The target Tycho hard fork time will be:

• Testnet: 2024-04-17 05:07:22 AM UTC
• Mainnet: To be determined, could be around Mid of Jun 2024

After Tycho hard fork, BSC will also support Blob Transaction, which will provide similar mechanism as Ethereum EIP-4844. And BSC L2 rollup could take advantage of it to reduce the rollup cost.
If you have any question about it, pls refer: FAQ: About EIP-4844 on BSC
