The zkBridge cross-bridge is set to support BNB Chain Haber and Tycho hard forks. This upgrade will introduce several changes to zkBridge. A new field, WithdrawalsHash, will be introduced in the block header, which will change the calculation logic in the BlockHash. The BlockHash verification related logic in the circuit will be updated to incorporate the newly added field into the BlockHash calculation.
Additionally, a new transaction type, BlobTxType, will be introduced, which will impact the calculation of the root of transaction receipts. However, this change will not affect zkBridge contracts. These updates are expected to improve the functionality and efficiency of zkBridge, enhancing its role in the blockchain ecosystem.
