List of "Color" Protocols


I was looking around for a comprehensive list of different protocols that are promoting “colored coin” concepts and was hoping others can help me fill in the gaps.

Open Assets -

CoinSpark -

Ascribe -

PoE -

Colu -

Monograph -

Eternity -

Omni Layer -

It appears that OpenAsset & CoinSpark are the two largest use cases that take advantage of the OP_RETURN

Did I miss any?


Colu also uses OP_RETURN for asset transfer data.
