According to Foresight News, the cross-chain bridge zkBridge will support BNB Chain Haber and Tycho hard forks. The impact of this upgrade on zkBridge includes: the introduction of new fields in the block header, such as WithdrawalsHash, which leads to changes in the calculation logic of BlockHash. Modify and update the logic related to BlockHash verification in the circuit to include the newly added fields in the BlockHash calculation. At the same time, a new transaction type BlobTxType is introduced, which affects the calculation of transaction receiptsRoot, but this change has no effect on the zkBridge contract.
