@Excalibur I agree GROUP is bloat-tastic, but Vermorel's paper seems very "cart-before-the-horse", and seems to overlook other existing locations for meta-data persistence.
What do you mean by other existing locations for meta-data persistence? memo.cash uses OP_RETURN and is basically a proof of concept of Tokeda concept
I have found space for storage of persistent metadata without additional opcodes.
