Career

Amaury Séchet, known as deadalnix, led Bitcoin ABC, the software that launched Bitcoin Cash in 2017[1]. He told Bitcoin Takeover that the original plan was an extension block, and that Bitcoin ABC was started when that did not work[2]. He said ABC was its own fork of Bitcoin Core rather than a reuse of XT, Classic or Unlimited[3].

Two more splits

In 2018, Bitcoin SV split away after the nChain camp rejected ABC-led changes; in 2020 his own chain left Bitcoin Cash over an 8% developer fund and became eCash (XEC)[2]. Kurt Wuckert Jr. gave the opposing view of that period on S17 E39[4].
