RE: The HF20 problems were anticipated by intelliguy -- no one listened. (Open Letter to STEEMIT)
I got a reply from dan a long time ago about this very thing.
He was adamant about just replaying from the beginning, even when he was talking about using blockchain for MMORPG backends. (when 99% of that data would be useless, as in your HP is at 100% most of the time, and the game doesn't care how much you lost in last week's fight)
And what really sucks this hard fork is that they were off by orders of magnitude.
yesterday - NEGATIVE 600 quadrillion
today - positive 400 billion (and falling fast, from manual commenting)
That there is missing the ball park.
And, i very much agree that back to back massive hits was a bad idea.
I sincerely appreciate your comment, thank you.
Replaying blockchains from genesis --- without snapshots -- is stupid. It's not sustainable, scalable, or an efficient use of bandwidth or resources.
When will we learn?
There is a way to sign, randomly verify snapshot data by asking for random blocks... using checksums, etc.
Real design and engineering needs to take place.
You have to walk, before you can run. For now... we seem to do a lot of running without realizing we're need the elementary stuff done first.
Time to go back to the drawing board, and fix what is not conducive to our future
Who should go back to the drawing board? The same guys that weren't experienced enough in the first place, hoping they learned 'all' lessons by now? If a team in a company were to do this we'd just replace them...
Whoever "can". It's never too late to realize what you should be doing.
