Zcash vs Aurora

The Zcash network is decentralized, self-funded and built with cutting-edge cryptography. Zcash is a cryptocurrency built to empower economic freedom. It is similar to Bitcoin in its design — in fact, Zcash was created from the original Bitcoin code base — but it uses a privacy technology that encrypts transaction information and allows users to shield their assets.

Aurora is a Virtual Chain built on NEAR. The first of many. It’s, at the same time, the sandbox and the proof of the robustness of the parent protocol. It’s a smart contract - probably the most complex that exists - that is also an Ethereum Virtual Machine, providing a turn-key solution for developers to operate their apps on an Ethereum-compatible, high-throughput, scalable and future-safe platform, with low transaction costs.
