eCash vs Polkadex

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.

Polkadex is a decentralized exchange (DEX) built on the Polkadot network. It offers high-performance, low-latency trading with a fully decentralized order book. Users can trade assets across different parachains within the Polkadot ecosystem and external blockchains connected via bridges. Polkadex uses L2 scaling solutions for fast, efficient trading and operates on a non-custodial model, allowing users to retain control of their funds at all times.
