I was wondering has there been anything built that utilizes the blockchain as a database storage system either in Bitcoin or another Alt? Say I run the CMS Wordpress and I have a bunch of users. I want these user records which contain their name/phone/email/address sit on the blockchain and retrievable via the blockchain. It could be encrypted or not. These records can be retrieved within the CMS without the need to store it anywhere on the web server thereby replacing MYSQL. Well not replacing mysql completely, but only store selective data that is important.
Does anyone have something like this yet?
I know it can kind of be done on the Bitcoin Blockchain using OP_RETURN. But that only fits 40bytes at the moment. It's going to goto 80bytes eventually as it seems. Or is there another Alt more suited for this use case? One issue is redundancy, Bitcoin would have the most redundancy as its the most distributed with over 6000 nodes. Other alts could very well die and you'll lose all your data if they dont get more nodes up.
