eCash vs Optimism

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.

Optimism provides a Layer 2 scaling fix for Ethereum, greatly boosting its scalability and cutting down on gas fees. It maintains robust security measures and guarantees a smooth development experience. Through Optimistic Rollups, it enables swift transaction processing, positioning Ethereum as a viable option for deploying intricate and interactive applications.
