Re: [ANN][Datacoin] Datacoin blockchain start announcement (Minor code upd + logo)
It's nice to see some movement here 
This coin has a nice concept, I also like the scientific background.
I guess voting and comments could be submitted to the blockchain, they just need to refer to the original torrent via an id (the hash of the magnet link for example).
I think the HTTP servers should parse the data from the blockchain and store it in a database, this would also allow searching, just like collecting the votes for one torrent without scanning the whole blockchain.

I think a rating system and search function would be beyond the scope of Datacoin and is better left implemented by sites that would link to DTC files or by a derivative wallet. However, the core wallet should definitely implement user friendly uploads and downloads via txid or other identifiers.

Agree with this. Sending JSON to blockchain is not hard, but what if the user spams the blockchain with a 5 star rating to his torrent? A solution could be vote confirmations, where each vote has to be confirmed by another voter, but then again, how can you prevent people from voting for their rating? But the starting point in my solution is good in itself, so maybe work on something based on that?
How about a voting like in Memorycoin. The weight of a vote is determined by the Datacoin volume of the voters address. No matter how often someone votes, his vote would only count as high his balance. This could avoid spamming, but someone could just buy votes.
