My initial witness post was written over two years ago, so I thought it's about time I'm updating it.

Current Witness status

I'm currently ranked #74 (active 71), I broke into the Top 100 quite recently partly thanks to the exposure I got from my contributions to the Steemit Condenser and Wallet apps. At this current position, I'm witnessing in average 8 blocks per day giving me a Producer Reward of around 1.200 SP per block. However, due to the current low price of STEEM, this gives me only around USD $14.11 per week or about USD $59.98 per month, which is barely sufficient for me to rent a server to run the witness node. My expenses for all related projects (Hivemind node, @SteemSQL subscription, community bot server) are actually more than what I earn back from running my Witness, so I'm in fact paying out from my own pocket.

Additionally to my Witness operation on Steem, I'm also an active blogger and write content on various topics such as:

Outside of Steem, I'm a full time Web Developer working for SBS, an Australian national TV broadcast company. I'm an admin/moderator of a couple of Facebook groups related to worm farming and I'm the owner of https://thelittlewormfarm.com, I also love tending to my garden where I grow a lot of fruits and vegetables for the pleasure of my family, I also do photography to complement my blogs, I'm practicing Wu Xing Dao Kung Fu and I love fishing especially kayak fishing.


Current servers specs

Witness node

I recently upgraded my Witness server for the third time to the following specs:

  • Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz
  • 32 GB RAM (I'm still using ZRAM for an extra 30 GB useable memory in average)
  • 2x 256 GB SSD in RAID0 giving 512 GB effective disk space
  • Bandwidth: 1 Gbit/s

Hivemind node

I also run a Hivemind node that powers my Steem REST API initially created for my now suspended @steemtelly project but it is now powering other projects too. Its specs are as followed:

  • Intel(R) Atom(TM) CPU C2750 @ 2.40GHz
  • 32 GB RAM with ZRAM enabled
  • 250 GB SSD

I compile steemd the witness software that runs the blockchain myself and have my own scripts to help with setting up new nodes and do maintenance work, reducing time to get the server up and running.

Bots node

This node is a small VPS that runs NodeJS bots for the following projects, all of which runs inside a Docker container for portability:

Its specs are as followed:

  • Intel(R) Atom(TM) CPU C3955 @ 2.10GHz
  • 2 GB RAM
  • 50 GB SSD

IPFS Pinning node

This node is backing up @dtube and @dsound video/audio files in order to help preserve content for a longer period.

  • Cavium Thunder X ARM
  • 4 GB RAM
  • 100 GB SSD

My still active community contributions

Development work on some community apps

I've in several occasions submitted pull requests for bug fixes and feature requests for the Steemit Condenser and Wallet apps, some of which have been announced by @steemitblog and got me twice the title of Most Valuable Programmer of the week:

I've added the Keychainify feature to Steem Keychain:

Steemed Phish

Steemed Phish is a Chrome browser extension to make external links more visible and alert you on Phishing/Scamming links. It was injecting several little improvements to the Steemit Condenser app before those were also implemented in the app itself.

Community bots for Team Australia, Team NZ and Team VN
