The Anchor is a cross-chain fixed sized deposit/withdraw shielded pool.
It allows for users to deposit tokens on one chain and withdraw in another
one without linking the deposit to the withdrawal.
We will take inputs and do a merkle tree reconstruction for each node in the
path and check if the reconstructed root is inside the current root set.
The Mixer is a fixed sized deposit/withdraw shielded pool.
This is the simplest circuit in arkworks-circuits.
It implements a on-chain mixer contract that allows for users to deposit
tokens using one wallet and withdraw using another one. This system uses
zero-knowledge proofs so no private information about the user gets leaked.
