In what form are those rewards distributed? Some type of coin that lets them register more names (like in Namecoin)? Some alternate version of Bitcoin that only has use as a currency? Something else?
The DIANNA will have its own financial block chain like Bitcoin. If we cut the domain operations, it will function like Bitcoin cryptocurrency with its own block chain and own "coins".
Those coins will be used also like alternate currecy.
Actually, DIANNA operates like NameCoin, but:
- registration fee is returned to miners (not destroyed) and caused additional proportional difficulty overhead to be not free
- registration fee defined by free market agreements, not by system. System can only suggest its value at first stages like bitcoin tx fee
- coins are not used as a domain name carrier
The registration fee of DIANNA's chain will be defined by communty like fees in "post-apocalyptic" Bitcoin (when coinbase dropeed to low values at lately stages).
Will this allow for merged mining? (hit post, walked away, didn't see out didn't post due to new replies) Namecoin mining doesn't pay a high reward, but since it is bootstrapped to Bitcoin mining, mining Namecoin is essentially free, and any reward above 0, no matter how small, makes it still be worth it.
I am still not considered with this. Merged mining needs additional research. See posts above.
Are there any considerations for database sizes? I've read somewhere (take with grain of salt) that the current ICANN DNS database is over 10 terrabytes in size. That's not something regular home users can support. Will this database/blockchain eventually have to be relegated to a few large centralized data storage places?
The first thing is yes, this will be heavy.
The second is the words of Satoshi:
The networks need to have separate fates. BitDNS users might be completely liberal about adding any large data features since relatively few domain registrars are needed, while Bitcoin users might get increasingly tyrannical about limiting the size of the chain so it's easy for lots of users and small devices.
So the DIANNA won't be so popular due to big data sizes. Users will have to have a good hardware to run the full client.
Although, the lightweight clients (i.e. DNS clients) are possible. They will just listen to network and do not write whole database, but only needed namespace.
However I already thought to put the full block chain to DHT database and on clients keep only reasonable its part, other part will represented only as headers. If client need a full block record which it hasn't, he queries DHT for it. Since client has a hash of this block, he can verify whether DHT returned valid block.
Are there any considerations for growth? The part that concerns me about Namecoin is that block rewards are constant for long periods of time, which means the maximum number of registrations per year is limited. Will your chain generate a decreasing reward like Bitcoin, level rewards (eg 50 per block) for ever, growing exponentially (3% increase every year to keep up with population/technology/other growth), or something else?
I think the Bitcoin emission model is fine. 50 coins means 5E9 "coin quantums". One coin is int64 = 1E8. I think this is totally fine. Correct me if I mistake.
