That HZIOTA asset is interesting because it is similar to the kind of assets I have been considering issuing.
Even down to not having any decimals, just whole coins!
I had however assumed there would be no interest without automated redeeming of the asset, that was part of why I have been delaying. (I had been looking at some exchange code that supposedly would hold blockchain coins in multi-sig accounts and allow web-based buying and redeeming of tokens representing such coins.)
Partly because of such automation potentially turning out to be buggy or unreliable I had figured on starting with relatively low-value coins, specifically IXCoin and I0Coin, probably also GRouPcoin.
I am also considering using the no-hot-wallet approach adopted for
the Digitalis Open Transactions server, that is, freeze coins "forever" instead of constantly de-issuing and re-issuing the tokens that represent them as coins come and go from the system.
(That approach allows, for example. the use of coins whose blockchains are not necessarily very secure, by only issuing digital tokens representing coins that not only are in our possession/vaults but have also been there long enough for hard-code checkpoints in coin clients/daemons to have accumulated since, so that even if the chain is attacked those coins are still definitely in place, so attacks on the blockchain cannot remove the actual coins out from under the digital tokens that represent them. It also allows the entire blockchain to be obsoleted once each and every coin on the blockchain is safely in our vaults, so that the need to try to secure an insecure blockchain can go away.)
