Constants

const (
	// MaxStackSize is the maximum combined height of stack and alt stack
	// during execution.
	MaxStackSize = 1000

	// MaxScriptSize is the maximum allowed length of a raw script.
	MaxScriptSize = 10000

	// PayToWitnessPubKeyHashDataSize is the size of the witness program's
	// data push for a pay-to-witness-pub-key-hash output.
	PayToWitnessPubKeyHashDataSize = 20

	// PayToWitnessScriptHashDataSize is the size of the witness program's
	// data push for a pay-to-witness-script-hash output.
	PayToWitnessScriptHashDataSize = 32
)

const (
	MaxOpsPerScript       = 201 // Max number of non-push operations.
	MaxPubKeysPerMultiSig = 20  // Multisig can't have more sigs than this.
	MaxScriptElementSize  = 520 // Max bytes pushable to the stack.
)

These are the constants specified for maximums in individual scripts.

const (
	// LockTimeThreshold is the number below which a lock time is
	// interpreted to be a block number.  Since an average of one block
	// is generated per 10 minutes, this allows blocks for about 9,512
	// years.
	// consensus critical
	LockTimeThreshold = 5e8 // Tue Nov 5 00:53:20 1985 UTC
)

Variables

var Bip16Activation = time.Unix(1333238400, 0)

Bip16Activation is the timestamp where BIP0016 is valid to use in the blockchain. To be used to determine if BIP0016 should be called for or not. This timestamp corresponds to Sun Apr 1 00:00:00 UTC 2012.

Types

type SigHashType

type SigHashType uint32

SigHashType represents hash type bits at the end of a signature.

const (
	SigHashOld          SigHashType = 0x0
	SigHashAll          SigHashType = 0x1
	SigHashNone         SigHashType = 0x2
	SigHashSingle       SigHashType = 0x3
	SigHashAnyOneCanPay SigHashType = 0x80

	// SigHashMask defines the number of bits of the hash type which is used
	// to identify which outputs are signed.
	SigHashMask = 0x1f
)

Hash type bits from the end of a signature.
