AccountUpdateTree

Class which represents a tree of account updates, in a compressed way which allows iterating and selectively witnessing the account updates.

The (recursive) type signature is:

type AccountUpdateTree = {
  accountUpdate: Hashed<AccountUpdate>;
  children: AccountUpdateForest;
};
type AccountUpdateForest = MerkleList<AccountUpdateTree>;

Extends​

  • {"accountUpdate": HashedAccountUpdate.provable; "children": AccountUpdateForest.provable; "id": RandomId; }

Constructors​

new AccountUpdateTree()​

new AccountUpdateTree(value: {
  "accountUpdate": HashedAccountUpdate.provable;
  "children": AccountUpdateForest.provable;
  "id": RandomId;
 }): AccountUpdateTree

Parameters​

• value

• value.accountUpdate: Hashed\<AccountUpdate>= HashedAccountUpdate.provable

• value.children: MerkleList\<{ "accountUpdate": HashedAccountUpdate.provable; "children": MerkleListBase\<AccountUpdateTreeBase>; "id": RandomId; }>= AccountUpdateForest.provable

• value.id: number= RandomId

check()​

static check: (value: {
  "accountUpdate": HashedAccountUpdate.provable;
  "children": AccountUpdateForest.provable;
  "id": RandomId;
 }) => 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.accountUpdate: Hashed\<AccountUpdate>= HashedAccountUpdate.provable

• value.children: MerkleList\<{ "accountUpdate": HashedAccountUpdate.provable; "children": MerkleListBase\<AccountUpdateTreeBase>; "id": RandomId; }>= AccountUpdateForest.provable

• value.id: number= RandomId

Returns​
