Ordinals on Grin

2

I think Grin is about the most spam proof chain there is. Where spam is shorthand for inscribed arbitrary data. This is because

  1. Grin is scriptless. So there’s no scripts in which to embed data.

  2. Grin has no addresses. So you can’t embed data in a pretend address. (you can in other hybrid MW chains like Litecoin).

  3. Kernels only allow a few bytes of arbitrary data in past lock heights. If you spread such data over many kernels of one tx, then finding them among a block’s sorted kernels is a challenge.

  4. Outputs only allow some arbitrary data in the rangeproofs, much of which is only retrievable by the owner. Since I don’t understand BPs in detail, someone else will need to say how many bytes could be made publicly visible. It will in any case be a small percentage of the BP size of 674 bytes. And it suffers the same challenge of finding a tx’s outputs among a block’s sorted ones. Finally, it will disappear from most full nodes once the output is spent.
