TaikoEvents
This abstract contract provides event declarations for the Taiko protocol, which are emitted during block proposal, proof, verification, and Ethereum deposit processes.
The events defined here must match the definitions in the corresponding L1 libraries.
BlockProposed
event BlockProposed(uint256 blockId, address prover, uint256 reward, struct TaikoData.BlockMetadata meta)Emitted when a block is proposed.
Parameters
| Name | Type | Description |
|---|---|---|
| blockId | uint256 | The ID of the proposed block. |
| prover | address | The address of the assigned prover for the block. |
| reward | uint256 | The proposer's block reward in Taiko token. |
| meta | struct TaikoData.BlockMetadata | The block metadata containing information about the proposed block. |
BlockProven
event BlockProven(uint256 blockId, bytes32 parentHash, bytes32 blockHash, bytes32 signalRoot, address prover)Emitted when a block is proven.
Parameters
| Name | Type | Description |
|---|---|---|
| blockId | uint256 | The ID of the proven block. |
| parentHash | bytes32 | The hash of the parent block. |
| blockHash | bytes32 | The hash of the proven block. |
| signalRoot | bytes32 | The signal root of the proven block. |
| prover | address | The address of the prover who submitted the proof. |
BlockVerified
event BlockVerified(uint256 blockId, address prover, bytes32 blockHash)Emitted when a block is verified.
Parameters
| Name | Type | Description |
|---|---|---|
| blockId | uint256 | The ID of the verified block. |
| prover | address | The address of the prover that proved the block which is verified. |
| blockHash | bytes32 | The hash of the verified block. |
EthDeposited
event EthDeposited(struct TaikoData.EthDeposit deposit)Emitted when an Ethereum deposit is made.
Parameters
| Name | Type | Description |
|---|---|---|
| deposit | struct TaikoData.EthDeposit | The Ethereum deposit information including recipient, amount, and ID. |
BondReceived
event BondReceived(address from, uint64 blockId, uint256 bond)The following events are emitted when bonds are received, returned, or rewarded. Note that no event is emitted when a bond is kept/burnt as for a single block, multiple bonds may get burned or retained by the protocol, emitting events will consume more gas.
BondReturned
event BondReturned(address to, uint64 blockId, uint256 bond)BondRewarded
event BondRewarded(address to, uint64 blockId, uint256 bond)
