type CheckpointOracle ¶ Uses

type CheckpointOracle struct {
    // contains filtered or unexported fields
}

CheckpointOracle is a Go wrapper around an on-chain checkpoint oracle contract.

func NewCheckpointOracle ¶ Uses

func NewCheckpointOracle(contractAddr common.Address, backend bind.ContractBackend) (*CheckpointOracle, error)

NewCheckpointOracle binds checkpoint contract and returns a registrar instance.

func (*CheckpointOracle) Contract ¶ Uses

func (oracle *CheckpointOracle) Contract() *contract.CheckpointOracle

Contract returns the underlying contract instance.

func (*CheckpointOracle) ContractAddr ¶ Uses

func (oracle *CheckpointOracle) ContractAddr() common.Address

ContractAddr returns the address of contract.

func (*CheckpointOracle) LookupCheckpointEvents ¶ Uses

func (oracle *CheckpointOracle) LookupCheckpointEvents(blockLogs [][]*types.Log, section uint64, hash common.Hash) []*contract.CheckpointOracleNewCheckpointVote

LookupCheckpointEvents searches checkpoint event for specific section in the given log batches.

func (*CheckpointOracle) RegisterCheckpoint ¶ Uses

func (oracle *CheckpointOracle) RegisterCheckpoint(opts *bind.TransactOpts, index uint64, hash []byte, rnum *big.Int, rhash [32]byte, sigs [][]byte) (*types.Transaction, error)

RegisterCheckpoint registers the checkpoint with a batch of associated signatures that are collected off-chain and sorted by lexicographical order.

Notably all signatures given should be transformed to "ethereum style" which transforms v from 0/1 to 27/28 according to the yellow paper.
