You know me probably as developer of beem, an alternative python library for steem. I joined steem in 29.12.2017. In the first two months, I learned the fundamentals of steem and I was searching my niche.
I always wanted to write a huge python library and after studying the source code of python-steem, I knew that I will create an alternative python library for steem. Since the 14. Februar, I worked every free hour on beem, the alternative python library. I took the source code from python-bitshares and added 12944 lines of code. In total, I pushed 450 commits in which I added 70796 lines and in which I removed 49246 lines of python code and documentation.
(holgern is my github account name)
I discovered utopian-io and published regularly new post about newly added features there.
Currently, I'm working on the 36. release of beem and I've started a new project in which a pushed every hour updates about the full-node state to the account @fullnodeupdate. The full node state can be obtained by reading the json_metadata of this account. I will post in more detail about this project soon.
My commitment to steem
In the last 5 month, I invested a huge amount of my saving into steem. Until now, I never powered down. I'm trying to support all developer who posts for utopian-io by upvoting their content.
As I mentioned, I develop beem and I'm trying to help all steemit user, who want to use my library.
You can see my latest post about beem developement here: https://hive.blog/utopian-io/@holger80/update-for-beem-steemconnect-integration-and-bug-fixes.
I'm also visiting often the official steem github. I wrote Current state of hardfork 0.20.0 development - 30.05.2018 and found a bug in the steem source code (#1764) which leads to #2515.
I published a complete appbase-api call reference in this post: https://hive.blog/appbase/@holger80/api-methods-list-for-appbase.
My witness server setup
I rented a server with the following specification:
- 64 GB DDR4 RAM
- Intel® Core™ i7-6700 Quad-Core
- 1 GBit/s
- 2 x 240 GB SATA 6 Gb/s SSD
I installed Ubuntu 16.04 and I'm using the stable branch of the steem github. I did the following steps to assure that everything will run smoothly:
- ssh port is changed
- root login is disabled
- fail2ban is installed
- 4 GB swap partition is created
- zram compression is active
- I created a 131GB ram partition (2*RAM + SWAB - 1 GB)
- I compiled and installed steemd and cli_wallet (
LOW_MEMORY_NODE=ON,CLEAR_VOTES=ON,SKIP_BY_TX_ID=ONandCMAKE_BUILD_TYPE=Release) - I checked and added seed-nodes to the config file
- I replayed the blockchain and installed a systemd service for steemd
- Created a python pricefeed script which is started by crontab
Everything is running now and 40 GB RAM are used at the moment.

Hi @holger80, I'll check your python library as I'm interested to learn more about extracting information from the Steemit Blockchain.
Thanks for all the effort.
