eCash (XEC) is a cryptocurrency that emerged from the rebranding of Bitcoin Cash ABC (BCHA) in July 2021. Its development was spearheaded by Amaury Séchet, a prominent figure in the Bitcoin Cash community. eCash aims to combine the foundational principles of Bitcoin's decentralisation and robustness with innovative technologies, aspiring to become a digital currency that delivers on the promise of electronic cash. With a focus on fast transactions and low fees, eCash is built on the Avalanche consensus mechanism, which enhances its scalability and transaction speed. A key feature of eCash is its improvement in transaction privacy, making it practical for everyday financial operations. The transition to 8 decimal places, rather than the typical 2 of fiat currencies, marks its usability shift, enabling easier microtransactions. Overall, eCash strives to provide a user-friendly and efficient platform for digital payments and value exchange.
