Comment That's not what the blockchain is for (Score 5, Interesting) 46
The blockchain is already close to 40 GB in size, and now people want to store all sorts of other data (or metadata) in it. I can see this getting out of hand rather quickly.
Miners won't be able to store the entire chain anymore, so only a few archival nodes will still have it. Just how secure and accessible will your metadata be then?
