Guys, I've seen several concepts for overwriting\deleting 'old' or 'unnecessary' files. But it breaks the whole concept of Datacoin. Look: someone uploaded some kind of Wikileaks archive to Datacoin, then hackers who work for government accessed his computer got his keys and deleted this info. It will be practically the same as Dropbox\GDrive storage: if someone gets your credentials, he can delete any info he wants, it breaks the whole concept.
And I've talked many times about 'proof-of-storage', just now there are no ways to avoid cheating like creating bunch of VPS that are linked to one blockchain - 'I have 1000 machines with Datacoin', and actually it will be 1 copy of blockchain and many virtual machines linked to it.
Talking about colored chain - will it be secure and reliable?
I'm not arguing with you, it is just my point of view. I'm not head developer, maybe he will read our threads and see some features to implement. But just now I have opinion as described above.
I think the team behind DTC should listen to what the crypto-community have to say. I believe that DTC has huge potential, and the community is providing amazing feedback. Considering a minor change in the initial concept could actually make it even more successful.
The MAJOR value in Datacoin is that it positioned itself as a coin made for STORAGE, and that, IS THE WINNING CONCEPT!
Considering the way this concept was developed, it has end up creating two major issues: (1) the potential use for illegal files, and (2) the bloating of the blockchain. As a matter of fact, I wonder if the second issue is what is holding Cryptsy from start trading it in its platform.
Here is how I see this coin...
DTC should become the ultimate database of torrent files. That would be an extremely popular way of accomplish storage in crypto-currency.
That would solve problem number (1) and (2) at the same time. DTC would never be hosting any illegal files, just torrents (which are just links), and the blockchain would stay light as feather. Anyone could benefit from it by using a special block explorer to search for files.
This solution would never bloat the blockchain, and nobody would host illegal files in their computers. An ELEGANT solution, if I may!
Now, considering the above implementation, a special parameter could be added to DTC to define the file as hidden from public. That would prevent from ever appearing on the block explorer search results, so these hidden files would be only available for people who knew how to find them with a special access key. (I believe a crypto-expert can ship in to improve this concept to something better)
What we all should understand very clearly is the following...
People will RUSH to DTC if they understand is a reliable system for storage, but they will RUN FROM IT if they think they have any chance of being associated with the hosting of illegal files. This issue CANNOT be avoided with technical arguments, the community is being extremely vocal about it, and it MUST be addressed seriously. The team behind DTC development MUST find a solution for that to succeed.
Here's another way of putting this...
The success of DTC is directly related with convincing a massive amount of regular users and non-tech investors to adopt the coin. They ARE NOT GOING to invest in DTC if they think they think that to be something risky. THAT IS A FACT and that's why the community is so vocal about it.
What would you rather have? Keep the original concept with nobody investing in the coin, or make a small change and end up bringing the masses? Think about that.
