Add assertions to the proof to check if value is a valid member of type T. This function does not return anything, instead it creates any number of assertions to prove that value is a valid member of the type T.

For instance, calling check function on the type Bool asserts that the value of the element is either 1 or 0.

Parameters

• value

the element of type T to put assertions on.

• value.blockHashRoot: Field = Field

• value.blockNumber: Field = Field

• value.eternalTransactionsHash: Field = Field

• value.incomingMessagesHash: Field = Field

• value.networkStateHash: Field = Field

• value.proverStateRemainder: Field = Field

• value.stateRoot: Field = Field

toAuxiliary()

Parameters

• value?

the element of type T to generate the auxiliary data array from, optional. If not provided, a default value for auxiliary data is returned.

• value.blockHashRoot?: Field = Field

• value.blockNumber?: Field = Field

• value.eternalTransactionsHash?: Field = Field

• value.incomingMessagesHash?: Field = Field

• value.networkStateHash?: Field = Field

• value.proverStateRemainder?: Field = Field

Returns

any[]

An array of any type describing how this T element is made up of “auxiliary” (non-provable) data.

toCanonical()?

static optional toCanonical: (x) => object

Optional method which transforms a provable type into its canonical representation.

This is needed for types that have multiple representations of the same underlying value, and might even not have perfect completeness for some of those representations.

An example is the ForeignField class, which allows non-native field elements to exist in unreduced form. The unreduced form is not perfectly complete, for example, addition of two unreduced field elements can cause a prover error.

Specific protocols need to be able to protect themselves against incomplete operations at all costs. For example, when using actions and reducer, the reducer must be able to produce a proof regardless of the input action. toCanonical() converts any input into a safe form and enables us to handle cases like this generically.

Note: For most types, this method is the identity function. The identity function will also be used when the toCanonical() is not present on a type.

Parameters

• x

• x.blockHashRoot: Field = Field

• x.blockNumber: Field = Field

• x.eternalTransactionsHash: Field = Field

• x.incomingMessagesHash: Field = Field

• x.networkStateHash: Field = Field
