eCash

eCash (XEC) is a cryptocurrency that was previously known as Bitcoin Cash ABC (BCHA), which itself was a fork of Bitcoin (BTC) and Bitcoin Cash (BCH). The project was rebranded to eCash in July 2021 with the goal of positioning it as an electronic cash system designed to be used for everyday transactions. One of the main improvements eCash aims to achieve is significantly scaling transaction throughput, from 100 transactions per second to over 5 million. It also aims to reduce transaction finality times and establish a fork-free upgrade path for the protocol. To accomplish this, the eCash developers have laid out an ambitious roadmap that includes solutions like canonical transaction ordering, Schnorr Signatures, faster block propagation, and adaptive block sizes. eCash follows a similar supply model to Bitcoin, with a total supply of 21 trillion XEC tokens. The project was led by Amaury Sechet, who was the lead developer of Bitcoin Cash and created the Bitcoin Cash ABC fork that became eCash. Sechet has cited the need to reduce the number of decimal places as part of the rebrand, arguing that more user-friendly whole number denominations will aid in the coin's adoption. The eCash network uses a proof-of-stake (PoS) consensus mechanism called Avalanche, which is distinct from the Avalanche blockchain. This PoS layer was added as an upgrade to the original proof-of-work (PoW) consensus of the Bitcoin Cash ABC network. The developers are also aiming for eCash to be Ethereum Virtual Machine (EVM)-compatible and integrate with the decentralized finance (DeFi) ecosystem.
