Wormhole is an Omni Layer implementation on top of the Bitcoin Cash (BCH) blockchain. The project is open source, anyone can continue it (I don't recommend doing so). Links to resources are provided below.
Luke Nandibear is the new owner of this site. While not directly involved with the Wormhole project I did work at Bitcoin.com for 2 1/2 years back when the company was involved with the protocol.
