Functions

func Connect 

func Connect(accountKey *keystore.Key, config *ethereum.Config) (eth.Handle, error)

Connect performs initialization for communication with Ethereum blockchain based on provided config.

Types

type EthereumChain 

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

EthereumChain is an implementation of ethereum blockchain interface.

func (*EthereumChain) Address 

func (ec *EthereumChain) Address() common.Address

Address returns client's ethereum address.

func (*EthereumChain) BalanceOf 

func (ec *EthereumChain) BalanceOf(address common.Address) (*big.Int, error)

BalanceOf returns the stake balance of the specified address.

func (*EthereumChain) BlockCounter 

func (ec *EthereumChain) BlockCounter() chain.BlockCounter

func (*EthereumChain) HasMinimumStake 

func (ec *EthereumChain) HasMinimumStake(address common.Address) (bool, error)

HasMinimumStake returns true if the specified address is staked. False will be returned if not staked. If err != nil then it was not possible to determine if the address is staked or not.

func (*EthereumChain) IsActive 

func (ec *EthereumChain) IsActive(keepAddress common.Address) (bool, error)

IsActive checks for current state of a keep on-chain.

func (*EthereumChain) IsAwaitingSignature 

func (ec *EthereumChain) IsAwaitingSignature(keepAddress common.Address, digest [32]byte) (bool, error)

IsAwaitingSignature checks if the keep is waiting for a signature to be calculated for the given digest.

func (*EthereumChain) IsEligibleForApplication 

func (ec *EthereumChain) IsEligibleForApplication(application common.Address) (bool, error)

func (*EthereumChain) IsRegisteredForApplication 

func (ec *EthereumChain) IsRegisteredForApplication(application common.Address) (bool, error)

func (*EthereumChain) IsStatusUpToDateForApplication 

func (ec *EthereumChain) IsStatusUpToDateForApplication(application common.Address) (bool, error)

func (*EthereumChain) LatestDigest 

func (ec *EthereumChain) LatestDigest(keepAddress common.Address) ([32]byte, error)

func (*EthereumChain) OnBondedECDSAKeepCreated 

func (ec *EthereumChain) OnBondedECDSAKeepCreated(
	handler func(event *eth.BondedECDSAKeepCreatedEvent),
) (subscription.EventSubscription, error)

OnBondedECDSAKeepCreated installs a callback that is invoked when an on-chain notification of a new ECDSA keep creation is seen.

func (*EthereumChain) OnConflictingPublicKeySubmitted 

func (ec *EthereumChain) OnConflictingPublicKeySubmitted(
	keepAddress common.Address,
	handler func(event *eth.ConflictingPublicKeySubmittedEvent),
) (subscription.EventSubscription, error)

OnConflictingPublicKeySubmitted installs a callback that is invoked when an on-chain notification of a conflicting public key submission is seen.

func (*EthereumChain) OnKeepClosed 

func (ec *EthereumChain) OnKeepClosed(
	keepAddress common.Address,
	handler func(event *eth.KeepClosedEvent),
) (subscription.EventSubscription, error)

OnKeepClosed installs a callback that is invoked on-chain when keep is closed.

func (*EthereumChain) OnKeepTerminated 

func (ec *EthereumChain) OnKeepTerminated(
	keepAddress common.Address,
	handler func(event *eth.KeepTerminatedEvent),
) (subscription.EventSubscription, error)

OnKeepTerminated installs a callback that is invoked on-chain when keep is terminated.

func (*EthereumChain) OnPublicKeyPublished 

func (ec *EthereumChain) OnPublicKeyPublished(
	keepAddress common.Address,
	handler func(event *eth.PublicKeyPublishedEvent),
) (subscription.EventSubscription, error)

OnPublicKeyPublished installs a callback that is invoked when an on-chain event of a published public key was emitted.

func (*EthereumChain) OnSignatureRequested 

func (ec *EthereumChain) OnSignatureRequested(
	keepAddress common.Address,
	handler func(event *eth.SignatureRequestedEvent),
) (subscription.EventSubscription, error)

OnSignatureRequested installs a callback that is invoked on-chain when a keep's signature is requested.

func (*EthereumChain) RegisterAsMemberCandidate 

func (ec *EthereumChain) RegisterAsMemberCandidate(application common.Address) error

RegisterAsMemberCandidate registers client as a candidate to be selected to a keep.

func (*EthereumChain) StakeMonitor 

func (ec *EthereumChain) StakeMonitor() (chain.StakeMonitor, error)

func (*EthereumChain) SubmitKeepPublicKey 

func (ec *EthereumChain) SubmitKeepPublicKey(
	keepAddress common.Address,
	publicKey [64]byte,
) error

SubmitKeepPublicKey submits a public key to a keep contract deployed under a given address.

func (*EthereumChain) SubmitSignature 

func (ec *EthereumChain) SubmitSignature(
	keepAddress common.Address,
	signature *ecdsa.Signature,
) error

SubmitSignature submits a signature to a keep contract deployed under a given address.

func (*EthereumChain) UpdateStatusForApplication 

func (ec *EthereumChain) UpdateStatusForApplication(application common.Address) error
