Server Upgrades
- Once more, the dreaded upgrades. 32GB RAM is no longer sufficient to run a witness node, so I upgraded my main node to a dedicated server with 64GB RAM last night. The new node is synched and producing blocks normally. I switched to my backup server during the upgrade so the block production wasn't interrupted and there were no missed blocks.
- I've using zram on the seed node for a few weeks now since it's not a critical server, so I didn't upgrade it. It crashed two times because of wrong memory tweaks. It's fixed, hopefully it will be more stable.
- Note that the blockchain file is now over 81GB.
New Setup
| Server | CPU | RAM | Disk | Speed |
|---|---|---|---|---|
| Primary Witness (Scandinavia) | 8 cores | 64 GB | 480 GB SSD | 1 Gbit/s |
| Backup Witness (Europe) | 10 cores | 50 GB | 1200 GB SSD | 1 Gbit/s |
| Seed (Europe) | 6 cores | 24 GB | 600 GB SSD | 100 Mbit/s |
| Additional fail-over | 2 cores | 1 GB | 25 GB | 100 Mbit/s |
Witness Parameters
- My APR is at 0%.
- I'm setting my bias to 0% since the SBD price has been going down from the all time highs a few months ago and hopefully it will reach its $1 pegged value.
Miscellaneous News
- I'm currently positioned at Rank 30. Thanks to all my supporters. Only 7 missed blocks since I started witnessing 8 months ago.
- I continue to help users and witnesses on Steem.Chat. We had a very busy February month with the stuck accounts . And with the new signup system, lots of users are having trouble with their activation link. We keep forwarding their issues to Steemit's team to fix.
https://steemit.com/steemit/@drakos/explosion-in-steem-user-on-boarding - I created a new chart to monitor the fluctuations of the Reserve Ratio and Average Block Size, for those interested in that technicality.

Security Alert
Always be careful what you click and where those clicks are taking you. Lots of users have fallen for phishing websites like steemil.com and steewit.com
https://steemit.com/scam/@drakos/beware-of-clicking-links-in-phishing-comments-pointing-to-steemil-com
Think before you act. If you're browsing on steemit.com, you click something then you're taken to another website that looks exactly like steemit.com and where you have to LOGIN AGAIN, that's your red flag. Don't do it.
In a nutshell, DO NOT USE YOUR PASSWORD TO LOG ON STEEMIT. Use the Posting key, so if you get hooked by those scammers, at least you won't be giving them your password! Stash that password away, DO NOT LOSE IT, and ONLY use it under extreme necessity.

SBD is going down but the debt ratio is hight and rewards will continue to going down with the fall of the STEEM.
If the debt ratio reach 2%, the SBD print rate will decrease

Voted for Witness!
Hey dude. First proper day on here and just wanted to drop you a line to say cheers for all your valuable contributions regards account signup and also for sending me that sign up form in Steemit.chat. Honestly have no idea if it made a difference, but my account was verified soon after, so I'm guessing it might. Thanks, brother.
good day, excellent publication, it was very educational, I liked the way you wrote it, although there were parts where I got lost but in the end I could understand it I hope you take into account my humble comment, greeting from venezuela
Just voted for you as witness! Have been hearing and seeing some great things from you. Keep it up! You have our support!
Thanks :)
I don't understand the logic to set the bias to zero. If the bias is helping to drive the SBD to its intended value, and it is still 250% of its intended value, then why stop before it reaches the intended value?
It's a consensus parameter, we need the top 20 witnesses to do it in order to have any impact. You can consider my gesture as symbolic, since it had no impact whatsoever on the price. It was decided by the majority of the top 20 not to modify the bias and let the peg resolve on its own. A few months later, it is doing so, but that's because all the crypto market is downtrending.
Thanks for answering. I didn't realize that it is set by consensus. In that case it makes sense. No point in having a symbolic protest vote when the urgency for such a move is decreasing anyway.
I voted for youvaluable information ..we need to be very careful ...Thanks for sharing @drakos
Whoot upgrading to a 64 gb is the next best step @drakos... That's why am vehemently behind you cheering you on, @drakos for steem witness... You are doing a lot of good work for this community and we really appreciate you. @dee-y over and out.
Wow! Over 81 gigs? That is huge!
Thanks so much for all your great work. :)
This is really valuable and thank you for your constant help, in making us have the best experience on this platform. I wish i can vote for you a thousand times over as a witness, more than the once i already did. Well done, and thank you.
I understand why it should go down to the $1 value... but also :/
Great job drakos! Though we are not ranked 30 as a witness :P , We understand the importance of them to the community and are poised to play our part as a witness as well. I am curious as to which memory modification/tweaks you made to stabilize your node so perhaps i'll hit you up in chat about that.
Sorry I messed up voting for you as a witness the first time, but I fixed it now. Thank you for all you do for the Steemit community.
Well done drakos. Keep steeming for good stuff.
Drakos for witness! He helps members hands on by being active on steem chat and msp (so far that i've known). Vote Drakos for witness!
Well done @drakos. My witness server is around 95 GB RAM and i'm planning to create a seed node ASAP. Thank for the info
you are the best man, thank you for security alert, i just now have done the changing posting key. :D i was clueless.
hahhahahha so cute :D
is it easy to know about nodes and those configurations? I'm passionate about the subject but I do not know anything besides that I would not know where to look for guides to teach me ... how did you learn?
Another question, if you think SBD reaches $ 1 as before and if so, will it go back up? Is it better to save SBD or Steem?
Great. Thanks for the informations. Follow you.
Greetings from Brasil.
I imagine that placing 81 gb to the blockchain file will help the flow of blocks do not have collisions and work more quickly for the memory space that you placed, I think I understood that in the post or correct me if I'm wrong stoi learning a bit like this works
good drako I wish you the best of success I vote for you as a witness because I know you are always updating and steemit needs people like you who are always pushing the best of the best
Many thanks for your informative post about minnowsupport & pal including steemit.
Good post @drakos
I voted for you!
My friend recently lost her account on the Steemit, when she moved on the link in the comments to her post. She says that she did not enter her password, but she was seized with her accoutrement. It's very scary that all your works can be wasted in one second.
I wish you more blockchain file! Thank you @drakos for your warning, I will be cautious, it will be very unpleasant, ate my drawings, which I place on the boil down.
But if she lost her password nothing can be done, the account is lost and she will need a new one.If someone hacked/stole her account tell her to do an account recovery at https://steemit.com/recover_account_step_1
I gave this information, thanks for the help
April fools!?
@abh12345 , @drakos It's working fine here
Heh!
Interesting! I'm not even from 'down under' either!
