This module implements domain objects. A domain object is:
a logical container of purely domain information, usually represents a logical entity in the problem domain space
https://wiki.c2.com/?DomainObject
In effect, domain objects are representations of objects shared between other modules in this codebase. They also encapsulate helper functions which make it easy to use them with said modules.
A private key. Provides helper functions to do with passing it into a circuit in the right format, serialisation and deserialisation, and deep copying.
A public key. Provides helper functions to do with passing it into a contract function or circuit in the right format, hashing, serialisation and deserialisation, and deep copying.
Encapsulates a PrivKey and PubKey. Also provides genEcdhSharedKey which
generates an ECDH shared key from a public key and a private key.
The Command domain object represents a request by a user to cast a vote
and/or change one's public key.
The Message domain object is an encrypted Command and signature. That is, a
Message is a Ciphertext (defined in maci-crypto)
which is the encrypted Command and its Signature (also defined in
maci-crypto). In other terms:
Message = Encrypt([Command, Signature], Key)
Represents a User's votes in a Poll, as well as their next valid nonce.
Represents a leaf in the state tree, which maps public keys to voice credit balances, as well as the timestamp at which it was inserted.
Encapsulates a Groth16 zk-SNARK verifying key.
Encapsulates a Groth16 zk-SNARK proof.
