I think datacoin should not reward only the computation power of miner, but the fact of storing the blockchain too.
Hashpower is important to secure the network, but datacoin is about storage, so the one who store the blockchain should get a cut.

Right now, the guy who mine a block get the block reward + all the fee.

Instead of going to the miner, the fee should be spread between all the blockchains.
Mining recquire to store the blockchain too, but the fee shouldn't reward pure hashpower, but storaging.


I would go even further :
I think the reward per block (currently ~10DTC) should be spread too, not only the fees. Like a 50/50 split, 5dtc to the miner and 5 dtc to blockchains

To not bloat the blockchain with a lot of tiny transaction and to create a more fair distribution, i think all those block reward and fee should go to a single neutral adress. Then after like 1 days (1440 block), this adress would automaticly redistribute equally the reward to all blockchains with 100% uptime for that day (1440 block).


It would probably recquire a hardfork, but this would ensure people have interest in storing the entire blockchain. Because in the near future, blockchain could grow big very quickly and people would only mine on a pool, without storing the blockchain, because it's the same reward right now.


tl,dr : Storage of the blockchain need to be rewarded
