Ethan Heilman - Ethan notes he's affiliated with The Paragon Foundation (see below) and founder of Commonwealth Crypto Inc. TumbleBit contributor, a proposed second-layer solution for Bitcoin designed to assist scaling and anonymity/fungibility, also requires a "trivial" fee to do so.

The Paragon Foundation a.k.a. DAGLabs

DAG Labs, formerly Paragon Foundation, is presently developing their own Directed Acyclic Graph, a direct competitor to IOTA.

DAGLabs' solution relies on tech they call SPECTRE.

DAGLabs is in the middle of acquiring Series A funding.
