Abstract Value Members

  1. abstract def activatedScriptVersion: Byte

    Maximum version of ErgoTree currently activated on the network.

    Maximum version of ErgoTree currently activated on the network. The activation is performed via miners voting. The maximum version supported by the interpreter is defined by Interpreter.MaxSupportedScriptVersion. As a result, the execution of the Interpreter.verify method depends on the relation between max supported and activated version. (see docs/aot-jit-switch.md).

  2. abstract val costLimit: Long

    Hard limit on accumulated execution cost.

    Hard limit on accumulated execution cost. Exceeding it leads to CostLimitException to be thrown.

  3. abstract val extension: ContextExtension

    Prover-defined key-value pairs, that may be used inside a script.

  4. abstract val initCost: Long

    Initial value of execution cost already accumulated before Interpreter.verify(or prove) is called.

  5. abstract def toSigmaContext(extensions: Map[Byte, AnyValue] = Map()): Context

    Creates special.sigma.Context instance based on this context.

    Creates special.sigma.Context instance based on this context. The created instance contains all data represented using types form special.sigma package. These types are used internally by ErgoTree interpreter. Thus, this method performs transformation from Ergo to internal Sigma representation of all context data.

    extensions

    additional context variables which will be merged with those in the extension of this instance, overriding existing bindings in case variable ids overlap.

  6. abstract val validationSettings: SigmaValidationSettings

    Validation parameters passed to Interpreter.verify to detect soft-fork conditions.

  7. abstract def withCostLimit(newCostLimit: Long): InterpreterContext

    Creates a new instance with costLimit updated with given value.

  8. abstract def withErgoTreeVersion(newVersion: Byte): InterpreterContext

    Creates a new instance with currErgoTreeVersion updated with the given value.

  9. abstract def withExtension(newExtension: ContextExtension): InterpreterContext

    Creates a new instance with extension updated with given value.

  10. abstract def withInitCost(newCost: Long): InterpreterContext

    Creates a new instance with initCost updated with given value.

  11. abstract def withValidationSettings(newVs: SigmaValidationSettings): InterpreterContext

    Creates a new instance with given validation settings.
