eCash (XEC) emerges as the rebranded iteration of Bitcoin Cash ABC (BCHA), itself derived from forks of Bitcoin (BTC) and Bitcoin Cash (BCH). Positioned as a "cryptocurrency designed for use as electronic cash," eCash is solely focused on facilitating transactions for goods and services. The rebranding occurred on July 1, 2021, marking an effort to differentiate itself from its predecessor. Notable distinctions include the introduction of "bits" as the base units of eCash, replacing the cumbersome decimal places of Bitcoin Cash ABC. For instance, instead of sending 0.00001000 BTC, users would transfer 10 bits with eCash. Additionally, eCash incorporates a proof-of-stake (PoS) consensus layer known as "Avalanche," distinct from the blockchain Avalanche (AVAX). Following the rebranding, eCash announced a conversion of all BCHA coins to XEC at a ratio of one to one million. The developers of this cryptocurrency have outlined three primary objectives: Scaling transaction throughput from 100 transactions per second to over five million transactions per second. Enhancing the payment experience by reducing transaction finality time. Extending the protocol and implementing fork-free upgrades.
