eCash vs Kaia

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.

Kaia (ex. Klaytn), an open-source public blockchain created by South Korean internet giant Kakao, prioritizes the metaverse, gaming, and the creator economy. Tailored for the evolving on-chain landscape, Kaia underscores enterprise-grade reliability through its optimized, Byzantine Fault Tolerant (BFT)-based blockchain. Kaia's mission is to decrease the operational costs of blockchain applications, enhance accessibility for end-users, and streamline technology adoption across industries.
