Let's forget for a while about the political war, and other money-related shit... just focus on the purely technical aspects. As you probably know, or should know, Witnesses are the foundation that keeps

Hey, after months of being quiet, this is my quick witness update to let you know, that my servers are still running, are up to date and I'm still producing blocks ;-) As you probably already know, after

The last weeks were crazy for all witnesses. Bugs, crashes, blockchain issues, steemd upgrades in the middle of the night and never ending replays, but finally... HF20 is live. I'm not going to comment

TLDR: no. 32GB servers with fast storage like SSD or NVMe are still good enough to run low memory nodes. The trick here is to keep the shared file in RAM (tmpfs device) and SWAP located on a fast disk(s).

As a witness, I use many different checks to monitor the reliability of my nodes. After few issues some time I got a good understanding which scripts can really catch the issue at an early stage and which

From a technical point of view, preparing a consensus node is the simplest thing we have to do as witnesses. The setup can be done in a few hours, it's just a running piece of software on a decent hardware.

Hey, since my last witness update, I have spent a lot of hours trying to understand how the Steem bandwidth acts and I summarized my findings in my last post "What is behind the Steem bandwidth

The last bandwidth issues inspired me to start my own debugging. I'm an OPS guy and when I'm facing issue I need to understand it and find the root cause. Steem Blockchain provides a bunch of raw data,

Jeśli zastanawiasz się dlaczego widzisz ten komunikat to znaczy, że prawdopodobnie przekroczyłeś limit dostępnej przepustowości... albo... blockchain Steem zaczął się bronić ;-) Co to jest bandwidth

First of all this is not an issue, this is excepted behaviour. Yesterday (1/6/18) the Steemit Inc decommissioned obsolete steemd.steemit.com RPC node as they communicated few times before. The new public

Happy New Year!   Witness #134 here and this is my update. I started the new year 2018 in the birth room, where my second daughter was born, and this is the best start I could have imagined. ;-) My witness

Każdego dnia polska społeczność powiększa się, co świetnie widać po ilości postów które pojawiają się w kategorii #polish. Większość z nas dołączając do platformy musiała się jej nauczyć, poznać wiele

No i nadszedł ten dzień... trwało to ponad 34 lata i broniłem się jak mogłem, chociaż jedyną linią obrony było myślenie, że to dla mnie za trudne... Uważam, że przez ten cały czas szło mi całkiem nieźle,

Merry Christmas! Witness #100 here and this is my status. I'm trying to engage myself in technical discussions about the Steem and share my technical knowledge with others. I have come across several questions

Yesterday I created Pull Request to adjust the size of the shared memory file (shared-file-size) to 20 GB in all default steemd configuration files as the shared file size already crossed 16 GB. Unfortunately

Hello, Since I started my journey as Steem witness I got 10 votes and currently sitting at #99. One week ago I was at #129 and producing 1 block for 3 days, today I produce ~3 blocks a day! ;-) Thank you

Hey, I would like to share few of my Linux tricks and commands I use in day to day work. I know everyone has own best practices but I hope that maybe some of the following will be useful for you too ;-)

Hello, Since my last witness update I got big vote and my position jumped from #172 to #128 and so far I produced 3 blocks! Yes... I count them ;-) Despite the fact these are only 3 blocks, I could see

Ubuntu 16.04 is very popular Linux distro and probably most of fresh Linux users use it. The problem with running steem-python on Ubuntu 16.04 is that the Ubuntu comes with Python 3.5 and steem-python

Yesterday I generated my first block as a witness. But what does it actually mean? Blockchain, just as the steel chain consists of many pieces joined together. In the case of steel chains these are small
