eCash

eCash (XEC) is led by Amaury Sechet, who was the lead developer of Bitcoin Cash (BCH). Sechet forked the Bitcoin Cash blockchain to establish the predecessor of eCash, Bitcoin Cash ABC (BCHA). He then decided to rebrand Bitcoin Cash ABC and establish a new brand identity for eCash. Sechet explained that reducing the decimal places would help with the adoption of the coin. Prior to his involvement in cryptocurrencies, Sechet worked as a software engineer at Facebook and a lead developer at Stupid D Compiler.

The developers of eCash (XEC) plan to make the coin Ethereum Virtual Machine (EVM)-compatible and interoperable with the decentralized finance (DeFi) sector on Ethereum (ETH). They have laid out an ambitious roadmap to achieve five core missions: ensuring anonymous transactions, immutable transactions, near-zero transaction fees, globally secure transactions with fast finality, and designing the coin's infrastructure as a public good. To accomplish this, they plan to implement solutions like canonical transaction ordering, Schnorr Signatures, faster block propagation, UTXO commitment, and adaptive block sizes to enable scalability up to 50 transactions per user per day for 10 billion users.

In contrast to the Bitcoin Cash ABC (BCHA) network, which is secured using a proof-of-work (PoW) consensus mechanism, the developers of eCash plan to add proof-of-stake (PoS) in the form of "Avalanche post-consensus." This layered approach will leverage the benefits of both PoW and PoS, providing enhanced security and fork-free upgrades, as well as enabling advanced scripting capabilities. The Avalanche layer will be added on top of the existing PoW to improve transaction finality and overall network security.
