Witness Update - Primary witness now in Sweden + SteemEngine development
It's been a while since I've made one of these, but I've been extremely busy with many things.
Over the past few months, I've been spending a lot of time working on @privex related projects, and most recently, SteemEngine (tired of waiting for SMTs? @aggroed, @harpagon and @yabapmatt already made them a reality!)
Tl;Dr; version
Released an open source Python library for SteemEngine,
with full support for sending + issuing tokens, as well as account historyReleased @privex 's Python JSONRPC Library for painless interaction with
JSONRPC nodes such assteemd,bitcoind, etc.Various improvements to @privex 's Python Log Helper library -
a very useful library to simplify Python'sloggingAPI.Used internally by @privex , @anonsteem , and several other projects I've built
Released @privex 's IPMI Slot Manager script as open source, written by us
to make managing multiple physical servers over IPMI much easier.Spent 100's of hours developing CryptoToken Converter - a highly modular
and robust system, designed to facilitate fast and painless conversion between different cryptocurrencies and/or tokens.Many hours have been behind the scenes, working on @privex 's Sweden region, getting closer to launch each day.
Our Swedish region is currently running as a private beta with several Steem witnesses and third-party developers battle testing
it, before we release it to the public.Set up my new witness server in Sweden, running on @privex 's own network, with relatively high end hardware.
Sweden Witness
In mid-February, @privex received several high-end Haswell-based Intel Xeon servers for our Swedish region. I purchased two of them from
the company (i.e. I own the physical servers, they're not rented).
On Friday (29 Mar), I finally set up one of the servers as my new Primary Witness Node, helping to reduce the current
centralization of witness servers in Germany.
The witness server is hosted at @privex's Sweden Datacenter, running on Privex's physical network and IP space, with
a blazing fast 10gbps network connection.
| Specifications | |
|---|---|
| CPU | 2x 10c/20t Intel Xeon E5-2660 v3's (Haswell) running at 3.3ghz turbo |
| RAM | 128gb of DDR4 ECC RAM @ 2133mhz |
| Disks | 2x 500GB Samsung 970 EVO's (PCI-e NVMe) running in RAID 0 |
| Network | 10gbps (yes, 10,000 mbps) via Privex Inc. (AS210083, we're a real ISP now) |
| Power | Dual hot-swap PSUs, each connected to a separate power feed protecting it from power surges/outages |
This server has now been set as my Primary node, and started producing blocks on Friday, 29 Mar 2019, at approximately 10:10 PM UTC-0.
I now have a total of four geo-diverse witness servers, ensuring reliable block production as a top 20 witness:
- Sweden (Primary)
- 2x Xeon Haswell 2.6ghz (3.3ghz turbo), 128GB DDR4 ECC 2133mhz, 2x 500gb Samsung 970 EVO PCI-e NVMe
- Finland 1 (Secondary)
- 2x Xeon Skylake 3.8ghz, 64GB DDR4 ECC 2400mhz, 2x 512gb Samsung PM981 512gb PCI-e NVMe
- Finland 2 - (Tertiary)
- Core i7 Kaby Lake 3.6ghz, 64GB DDR4 2133mhz, 2x 500gb Micron SSD
- Germany (Last line, oldest and weakest server)
- Core i7 Sky Lake 3.4ghz, 64GB DDR4 2133mhz, 2x Crucial 500gb SSD
CryptoToken Converter
Open Source
CryptoToken Converter is an open source project released under the GNU AGPL 3.0.
You can find it HERE on Privex's Github
What can it do?
This project was originally developed to be used by SteemEngine, however it has been designed
to fit many different purposes, for example:
- It could be used to run an instant crypto converter site, similar to @blocktrades or ShapeShift.
- It could be used to run a pegged token gateway, allowing either one-way or two-way conversions between a pegged token, and the
asset which it's pegged against (e.g. Bitcoin <-> Pegged Bitcoin Tokens) - The payment handling code is designed to be robust and reliable, it can be taken and used for handling any form of cryptocurrency payments
Out of the box, it supports / includes:
- Sending, issuing and receiving SteemEngine Tokens
- Sending and receiving any cryptocurrency which has a coin daemon with a JSONRPC API that's backwards compatible with
bitcoind(e.g. Litecoin, Dogecoin, Bitcoin Cash) - Adjustable percentage exchange fee (default 0%) per conversion
- Automatically takes any blockchain fees out of the final amount sent
- Automatic conversion between user defined coin pairs, with adjustable "exchange rate" per coin pair
- Generates deposit addresses mapped to the coin pair for address-based coins such as Bitcoin
- Scans incoming deposit memos for account-based coins such as SteemEngine Tokens (they run on the Steem network)
- A user friendly admin panel with the ability to create user groups with different permissions, allowing you to create more restricted
admin accounts for your customer service team- Included in the admin is a Coin Health / Status dashboard, for quickly checking which coin daemons / APIs are functioning properly, and the balances of their wallet / account
Browsable REST API
The project includes a browsable REST API, making it extremely easy for developers to dig into the API and play with it, without having to use command line tools such as http (HTTPie) and curl, or having to write scripts.
Documentation
Unlike a lot of open source projects, many hours have been put into documentation, ensuring developers can easily install and configure it, as well as develop for it.
The documentation includes information on how to use the API, as well as a section on Coin Handlers, explaining with code examples how to add a new cryptocurrency network to the system.

Do you like what I'm doing for STEEM/Steemit?
Vote for me to be a witness - every vote counts.
Don't forget to follow me for more like this.
Have you ever thought about being a witness yourself? Join the witness channel. We're happy to guide you! Join in shaping the STEEM economy.
Are you looking for a new server provider? My company @privex offers highly-reliable and affordable dedicated and virtual servers for STEEM, LTC, and BTC! Check out our website at https://www.privex.io
Lots and lots of stuff man !
The gateway is very very interesting to me as well. I have few stupid doubts ...
You've made the Steemit Minute for today! Congrats!
Check out the Video Here: https://steemit.com/dtube/@reseller/hnpm1ao0
Glad to see what you are up to in the basement with the machines :)
I am really interested in that gateway, going to dig into the docs straight away, i have been working for the last two ears into a primitive token integration with discord and a parasite side chain while you guys were playing the big leages!
Since the main project is purely a REST API, everything is exposed via the API, so you could very easily
integrate a Discord bot with the API, simply build a chat command like this:
.convert fromtoken totoken destaddrThen, it simply fires off a request to
/api/convertand returns their deposit info. So easy :)@someguy123 and @nnnarvaez
Do you have a working websites that use this program to take a peek?
@someguy123,
Maybe you can open source the anom account creation too :)
Cheers,
@Yehey
That is what i have done for my token, i am looking forward migrating everything to a web page because millennial don't want functionality they want looks and hype.
But i made sure i had the functionality first :P
That’s a lot, now we can understand why you’re underground for a while now. Thanks for all these great sacrifices for our dear blockchain.
Awesome update and thanks for sharing. Hope someone picks this up and runs with it as it would be awesome to have a shapeshift to be able to convert steem ans sbds instantly into other tokens quickly and easily, with no fees.

We do already have Blocktrades, but sometimes they can take a large cut from the final amount.
It's quite possible for people to take the project and turn it into a ShapeShift for whatever coins they please, and thanks to the licensing (AGPL 3.0), they're required to keep it open source - so if you don't like their fees, someone can just take their code and run their own version with lower/no fees.
I saw the Steemengine tokens in the internal wallet prior to having an external steemit wallet so, am I to assume others will appear there soon too?

it's up to the different front ends to display. There's an api that means a dev can display them after ~half a day of work on any site.
Actually, a great article to read @someguy123. Very interesting topic since I work with APIs in my software engineering field. Good Luck man 😁💪
Hi @someguy123, Is the SteemEngine token different from the token that we know now on Steem (Steem and Steem Dollar)..?
If this has been launched hopefully this token has a market unlike some new tokens that have no market but have been released to the public ..
Steem Engine tokens run on sidechain until SMT is released, they will be native Steem token by then.
You just planted 0.10 tree(s)!
Thanks to @fuadsm
We have planted already
8197.02 trees
out of 1,000,000
Let's save and restore Abongphen Highland Forest
in Cameroonian village Kedjom-Keku!
Plant trees with @treeplanter and get paid for it!
My Steem Power = 24645.41
Thanks a lot!

This is big boy pant talking around here.
Definitely the dough resides at the genesis.
Why I didn’t go that route ?
Never to late to do good thing
Keep on postin
