Zcash vs eCash

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.

eCash is a blockchain project led by Bitcoin ABC, aiming to enhance L1 scalability, security, transaction speed, and cost-effectiveness. It integrates the Avalanche consensus protocol with its base PoW consensus, making it effectively a hybrid consensus network that is secured against 51% attacks and extensible via subnets and hard-fork free upgrades. These improvements address scalability concerns, enable rapid transaction finality, interoperability, and guarantee subcent fees. Despite these improvements, eCash remains committed to maintaining the decentralization principles of the original Bitcoin protocol. By prioritizing scalability and extensibility, eCash seeks to realize the vision of Bitcoin as a practical and accessible peer-to-peer electronic cash system.
