ICrossChainSync
Interface implemented by both the TaikoL1 and TaikoL2 contracts. It exposes the methods needed to access the block hashes of the other chain.
CrossChainSynced
event CrossChainSynced(uint256 srcHeight, bytes32 blockHash, bytes32 signalRoot)getCrossChainBlockHash
function getCrossChainBlockHash(uint256 number) external view returns (bytes32)Returns the cross-chain block hash at the given block number.
Parameters
| Name | Type | Description |
|---|---|---|
| number | uint256 | The block number. Use 0 for the latest block. |
Return Values
| Name | Type | Description |
|---|---|---|
| [0] | bytes32 | The cross-chain block hash. |
getCrossChainSignalRoot
function getCrossChainSignalRoot(uint256 number) external view returns (bytes32)Returns the cross-chain signal service storage root at the given block number.
Parameters
| Name | Type | Description |
|---|---|---|
| number | uint256 | The block number. Use 0 for the latest block. |
Return Values
| Name | Type | Description |
|---|---|---|
| [0] | bytes32 | The cross-chain signal service storage root. |
