Thank you for your quick reply.

I'll look into those.
Do you know if they have a kind of snapshot as well or if they keep the (even 0 value) tx in their chains?

So let's say I need 100 million tokens for a project and I wand a token which has no tx fees, a timestamp, small payload and is eternally stored in a blockchain.
It is fine to have a fork of something existing or to use something like ERC-20 or Omni Layer. It just need to fulfil the conditions mentioned above.

Why not IOTA? Because they have the snaphots which delete the zero value tx.
Any ideas what to use?

Cheers
