ECC says that using the Halo proving system within the protocol allows Zcash users to make private, trustless digital cash payments on mobile phones. This is made possible through a new address format called unified addresses, which removes the need to juggle multiple address types.
Another feature the company touted as being of interest to privacy-minded crypto enthusiasts is the ability to automatically route any ZEC received at a unified address to the latest shielded pool. This ensures that every Zcash transaction is shielded by default.
Zcash, a fork of the Bitcoin protocol, is known as a privacy coin. Zcash uses zero-knowledge proofs, a form of cryptography that can verify a legitimate transaction without exposing details such as potentially identifying information. Like Bitcoin, the total supply of Zcash is 21 million coins.
When Zcash launched in October 2016, its zero-knowledge proofs required a trusted setup phase that allowed users to construct and verify private transactions.
