Value Members

1.  object ScriptFlag
2.  object ScriptFlagFactory extends ScriptFlagFactory
3.  object ScriptFlagUtil extends ScriptFlagUtil
4.  case object ScriptVerifyCheckLocktimeVerify extends ScriptFlag with Product with Serializable

   See https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki for details.

5.  case object ScriptVerifyCheckSequenceVerify extends ScriptFlag with Product with Serializable

   See https://github.com/bitcoin/bips/blob/master/bip-0112.mediawiki for details.

6.  case object ScriptVerifyCleanStack extends ScriptFlag with Product with Serializable

   Require that only a single stack element remains after evaluation.

   Require that only a single stack element remains after evaluation. This changes the success criterion from "At least one stack element must remain, and when interpreted as a boolean, it must be true" to "Exactly one stack element must remain, and when interpreted as a boolean, it must be true". (softfork safe, BIP62 rule 6) Note: CLEANSTACK should never be used without P2SH.

7.  case object ScriptVerifyConstScriptCode extends ScriptFlag with Product with Serializable
8.  case object ScriptVerifyDerSig extends ScriptFlag with Product with Serializable

   Passing a non-strict-DER signature to a checksig operation causes script failure (softfork safe, BIP62 rule 1).

9.  case object ScriptVerifyDiscourageOpSuccess extends ScriptFlag with Product with Serializable
10.  case object ScriptVerifyDiscourageUpgradableNOPs extends ScriptFlag with Product with Serializable

    Discourage use of NOPs reserved for upgrades (NOP1-10) Provided so that nodes can avoid accepting or mining transactions containing executed NOP's whose meaning may change after a soft-fork, thus rendering the script invalid; with this flag set executing discouraged NOPs fails the script.

    Discourage use of NOPs reserved for upgrades (NOP1-10) Provided so that nodes can avoid accepting or mining transactions containing executed NOP's whose meaning may change after a soft-fork, thus rendering the script invalid; with this flag set executing discouraged NOPs fails the script. This verification flag will never be a mandatory flag applied to scripts in a block. NOPs that are not executed, e.g. within an unexecuted IF ENDIF block, are *not* rejected.

11.  case object ScriptVerifyDiscourageUpgradablePubKeyType extends ScriptFlag with Product with Serializable
12.  case object ScriptVerifyDiscourageUpgradableTaprootVersion extends ScriptFlag with Product with Serializable
13.  case object ScriptVerifyDiscourageUpgradableWitnessProgram extends ScriptFlag with Product with Serializable

    Making v1-v16 witness program non-standard.

14.  case object ScriptVerifyLowS extends ScriptFlag with Product with Serializable

    Passing a non-strict-DER signature or one with S > order/2 to a checksig operation causes script failure (softfork safe, BIP62 rule 5).

15.  case object ScriptVerifyMinimalData extends ScriptFlag with Product with Serializable

    Require minimal encodings for all push operations (OP_0...

    Require minimal encodings for all push operations (OP_0... OP_16, OP_1NEGATE where possible, direct pushes up to 75 bytes, OP_PUSHDATA up to 255 bytes, OP_PUSHDATA2 for anything larger). Evaluating any other push causes the script to fail (BIP62 rule 3). In addition, whenever a stack element is interpreted as a number, it must be of minimal length (BIP62 rule 4). (softfork safe).

16.  case object ScriptVerifyMinimalIf extends ScriptFlag with Product with Serializable

    Segwit script only: Require the argument of OP_IF/NOTIF to be exactly 0x01 or empty vector.

17.  case object ScriptVerifyNone extends ScriptFlag with Product with Serializable
18.  case object ScriptVerifyNullDummy extends ScriptFlag with Product with Serializable

    Verify dummy stack item consumed by CHECKMULTISIG is of zero-length (softfork safe, BIP62 rule 7).

19.  case object ScriptVerifyNullFail extends ScriptFlag with Product with Serializable

    Signature(s) must be empty vector if an CHECK(MULTI)SIG operation failed.

20.  case object ScriptVerifyP2SH extends ScriptFlag with Product with Serializable

    Evaluate P2SH subscripts (softfork safe, BIP16).

21.  case object ScriptVerifySigPushOnly extends ScriptFlag with Product with Serializable

    Using a non-push operator in the scriptSig causes script failure (softfork safe, BIP62 rule 2).

22.  case object ScriptVerifyStrictEnc extends ScriptFlag with Product with Serializable

    Passing a non-strict-DER signature or one with undefined hashtype to a checksig operation causes script failure.

    Passing a non-strict-DER signature or one with undefined hashtype to a checksig operation causes script failure. Evaluating a pubkey that is not (0x04 + 64 bytes) or (0x02 or 0x03 + 32 bytes) by checksig causes script failure. (softfork safe, but not used or intended as a consensus rule).

23.  case object ScriptVerifyTaproot extends ScriptFlag with Product with Serializable
24.  case object ScriptVerifyWitness extends ScriptFlag with Product with Serializable

    Support segregated witness.

25.  case object ScriptVerifyWitnessPubKeyType extends ScriptFlag with Product with Serializable

    Public keys in segregated witness scripts must be compressed.
