Steem 0.20.3

Ladies and gentlemen, we have successfully forked into Steem 0.20.3.

It didn't go without a hickup unfortunately. After last weeks troubles with an unscheduled fork because of a bug where versions 0.19.x and 0.20.x didn't come to a consensus on an activity, we had some issues when the fork happened yesterday at 15:00 UTC.

We did successfully fork to version 0.20.2, but nobody could do anything.
This was because of the new Resources Credits system and a bug that set everybody's RCs to a very large negative value, instead of zeroing-out and start generating. Without RCs, no transaction could be made on the blockchain, and thus, it could take weeks before people would have regenerated their RCs to a point where they could do anything at all. Not desirable to say the least.

It wasn't the smoothest of forks to say the least, but all witnesses (yours truly included) were right on the ball.
The steem.chat witness channel was absolutely buzzing with activity and everybody was wondering what happened and trying to find a solution. Luckily, the issue was quickly found and patched, meaning the master is now version 0.20.3
Obviously, @blockbrothers started applying the update as soon as it was announced.

Replay value

The problem though, was that every witness had to replay¹ the entire blockchain on their witness server. Because of the size of the blockchain, this could mean anywhere between 3 up to 6,7 hours of replay (this depends on the speed of the witness servers processor, amongst other things). Therefore, the first witnesses to run on 0.20.3 didn't come up until about 5,6 hours in total after the scheduled hardfork.

Upward and onward

Now that the majority of the witnesses is running version 0.20.3, more and more peoples Resource Credits have been reset to 0 and are regenerating (think of it like having spent all your voting power).

It will take at least a week before Resource Credits will find equilibrium as to which transactions cost what amount of RCs.

at the time of this post, these are roughly the costs:

Action	Recource Credits
Account claim	22,370,972,773,345
Voting	1,823,055,590
Unvoting	538,519,849
Posting (short text)	9,185,887,926
Post Editing (short text)	6,225,059,861
Commenting (short text)	9,215,918,695
Comment editing (short text)	12,346,377,665

Give or Take a few.

As a rule of thumb, your maximum Resource credits are roughly two billion times your SteemPower.So for instance, to cast an upvote, you will roughly need 1sp right now, but I'm sure that will come down in the coming days, while the RC code figures out the costs of all transactions on the blockchain.

We're glad we've made it to the other side and seeing everybody slowly coming back 'online'

Happy Hardfork 20 !
