Full Changelog: v0.0.1...v0.0.2

v0.0.1

Initial release that contains full featured privacy preserving tokens based on the UTXO model using ZKP to demonstrate transaction proposal correctness.

Fungible tokens

• anonymity + offchain secrets communication
• anonymity + onchain encryption
• anonymity + hiding spending graph
• anonymity + onchain encryption + hiding spending graph
• anonymity + hiding spending graph + privacy-preserving KYC
• anonymity + onchain encryption + hiding spending graph + non-repudiation

Non-Fugible tokens

• anonymity + offchain secrets communication
• anonymity + hiding spending graph

Programmability

• zkDvP contract that demonstrates the programmability of Zeto by coordinating between a fungible Zeto and a non-fungible Zeto

Golang SDK

• to be used alongside go-rapidsnark to generate ZK proofs and manage the Zeto UTXOs

ZK Circuits

All the zero knowledge proof circuits, based on circom, are included and come with unit tests

Integration Tests

A suite of comprehensive integration tests are included in golang (/go-sdk/integration-test), js (/zkp/js/integration-test) and hardhat (/solidity/test). They are the best source of reference for how to write applications to interact with Zeto tokens
