OffchainStateCommitments

Commitments that keep track of the current state of an offchain Merkle tree constructed from actions. Intended to be stored on-chain.

Fields:

  • root: The root of the current Merkle tree
  • actionState: The hash pointing to the list of actions that have been applied to form the current Merkle tree

Extends​

check()​

static check: (value: {
  "actionState": Field;
  "root": Field;
 }) => void;

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.actionState: Field= Field

• value.root: Field= Field

Returns​

void

toAuxiliary()​

static toAuxiliary: (value?: {
  "actionState": Field;
  "root": Field;
 }) => any[];

A function that takes value (optional), an element of type T, as argument and returns an array of any type that make up the "auxiliary" (non-provable) data of value.

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.actionState?: Field= Field

• value.root?: Field= Field

Returns​

any[]
