eCash: A New Bitcoin-Based Execution Layer
eCash is a Proof-of-Work (PoW) UTXO network that incorporates Avalanche pre-consensus to achieve approximately two-second transaction finality. The combination of PoW and Avalanche provides a distinctive security model, with PoW ensuring chain production and independent mining security, and Avalanche facilitating rapid pre-consensus to prevent conflicting transactions. eCash extends the UTXO model by introducing eTokens for native colored-coin assets, covenants for reliable financial applications, and subnets for specialized functionality without turning the base protocol into a smart-contract platform. The core proposition is a coherent UTXO architecture combining Bitcoin-style PoW, Avalanche finality, native assets, covenant-based decentralized finance (DeFi), protocol governance, and practical scaling.
