aelf vs eCash

aelf is primarily a multi-chain parallel computing blockchain network which was created to address several of the limitations of traditional blockchain systems, such as performance bottlenecks and data complexity. aelf's vision is to be a 'Linux Ecosystem' equivalent for a blockchain that incorporates state-of-the-art IT design principles, which in particular allows developers to customise Chains to meet their own needs.

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.
