Ethereum's private trading program Hopper open source code, released mobile application beta

Last week, the Ethereum privacy trading program Hopper announced full open source code and released the iOS mobile application beta. Hopper uses the Zero Knowledge Proof (ZKP) technology to "mix" user transactions, allowing users to deposit ETH into Hopper Smart Contracts and withdraw funds from another account. At present, users can only store one ETH at a time to remain anonymous. Hopper also reminds that because the application is still in the internal testing phase, there is no risk of losing funds due to full audit.
