Functions

func BurnGas

func BurnGas(ic *interop.Context) error

BurnGas burns GAS to benefit NEO ecosystem.

func CheckHashedWitness

func CheckHashedWitness(ic *interop.Context, hash util.Uint160) (bool, error)

CheckHashedWitness checks given hash against current list of script hashes for verifying in the interop context.

func CheckKeyedWitness

func CheckKeyedWitness(ic *interop.Context, key *keys.PublicKey) (bool, error)

CheckKeyedWitness checks hash of signature check contract with a given public key against current list of script hashes for verifying in the interop context.

func CheckWitness

func CheckWitness(ic *interop.Context) error

CheckWitness checks witnesses.

func GasLeft

func GasLeft(ic *interop.Context) error

GasLeft returns remaining amount of GAS.

func GetCallingScriptHash

func GetCallingScriptHash(ic *interop.Context) error

GetCallingScriptHash returns calling script hash. While Executing and Entry script hashes are always valid for non-native contracts, Calling hash is set explicitly when native contracts are used, because when switching from one native to another, no operations are performed on invocation stack.

func GetEntryScriptHash

func GetEntryScriptHash(ic *interop.Context) error

GetEntryScriptHash returns entry script hash.

func GetExecutingScriptHash

func GetExecutingScriptHash(ic *interop.Context) error

GetExecutingScriptHash returns executing script hash.

func GetInvocationCounter

func GetInvocationCounter(ic *interop.Context) error

GetInvocationCounter returns how many times current contract was invoked during current tx execution.

func GetNetwork

func GetNetwork(ic *interop.Context) error

GetNetwork returns chain network number.

func GetNotifications

func GetNotifications(ic *interop.Context) error

GetNotifications returns notifications emitted by current contract execution.

func GetRandom

func GetRandom(ic *interop.Context) error

GetRandom returns pseudo-random number which depends on block nonce and transaction hash.

func GetTime

func GetTime(ic *interop.Context) error

GetTime returns timestamp of the block being verified, or the latest one in the blockchain if no block is given to Context.

func GetTrigger

func GetTrigger(ic *interop.Context) error

GetTrigger returns the script trigger.

func Log

func Log(ic *interop.Context) error

Log logs the message passed.

func Notify

func Notify(ic *interop.Context) error

Notify should pass stack item to the notify plugin to handle it, but in neo-go the only meaningful thing to do here is to log.

func Platform

func Platform(ic *interop.Context) error

Platform returns the name of the platform.
