Ah, one more thing. I also don't quite follow the idea with content distribution - there are projects dedicated to this feature solely. What makes you better in this aspect?
The customer receives reliable data storage at an affordable price. The hoster receives a fee for data storage and the ability to use free disk space. The miner is rewarded for creating blocks and verifying transactions. The proxy receives a reward for data transfer.
Exactly! Customer gets supersafe and affordable data storage and transmission. Host gets a reward for data storage along with an additional distribution channel. Miner is remunerated for verifying transactions and forging blocks. Proxy is rewarded for data transmission.
