RE: The Investing World No Longer Makes Sense!
As a coin developer myself, I have to constantly keep myself updated with development of cryptocurrency as an industry... Some months ago there was talk about discarding old data from blockchain that is not supposed to change anymore neither is needed to preserve integrity of still used data. This includes for example all transactions with all outputs already spent. When block has no transactions that have unspent outputs, it will be pruned from blockchain data that is synced with other peers or stored on disk. In case of Steem, it could also include previous copies of edited posts and comments when the edit window has expired. This would require all new nodes to be able to skip those pruned blocks without risk of spontaneous chain split, essentially explicitly setting and propagating dynamic checkpoint on first block that is not pruned yet.
What about if the editing option window is never closed?
Obviously then last N versions would be preserved...
That doesn't seem to be possible then with the current tech without a blockchain eventually toppling over on itself.
It will require some complex changes in the daemon code but I'm confident some coin is already planning such change...
Well, whatever one coin does, steem could hopefully just implement or copy.
Most coins are based on another coin, incorporate improvements from other coins, and try make the whole better.
As a coin developer, I can name base coin I used, coins I borrowed improvements from and how I made the whole better...
Basically the only thing that matters then is the community and integrations. If those are big, the coin can become whatever it needs to be.
