eCash vs Integritee

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.

Integritee is a blockchain project focused on providing privacy-preserving solutions for dApps and smart contracts. It aims to enable confidential computing on public blockchains, allowing sensitive data to be processed securely without compromising privacy. Integritee utilizes trusted execution environments (TEEs), such as Intel SGX, to create secure enclaves where data can be processed confidentially. This ensures that data remains encrypted and inaccessible to anyone, including the network validators or operators, while it is being processed. This idea opens up new possibilities for privacy-focused applications in finance, healthcare, and so on.
