eCash(XEC)

Overview

eCash (XEC) is a Layer-1 digital cash network developed by Bitcoin ABC and launched on November 15, 2020. It distinguishes itself from earlier Bitcoin clients by integrating Avalanche consensus with its core proof-of-work (PoW) layer, forming a Nakamoto/Avalanche hybrid design.

This hybrid consensus gives the chain properties such as instant transaction finality, staking rewards, extensibility through subnets, and flexible protocol governance. Its published roadmap sets three main goals: scaling throughput from roughly 100 tps toward more than 5,000,000 tps, reducing transaction finality to under three seconds, and establishing fork-free protocol upgrades for more iterative development.
