Honest Price Feeds for Bitshares Market Pegged Assets
We are currently feeding an HONEST price hourly to 9 BitShares Market Pegged Assets:
These are backed by the BTS core token as collateral, meaning you "borrow them into existence" with Bitshares:
HONEST.CNY (CHINESE YUAN)
HONEST.BTC (BITCOIN)
HONEST.USD (US DOLLAR)
HONEST.XAU (GOLD)
HONEST.XAG (SILVER)
HONEST.ETH (ETHEREUM)
HONEST.XRP (RIPPLE)
These are backed by HONEST.BTC as collateral, meaning you "borrow them into existence" with Bitcoin:
HONEST.ETH1 (ETHEREUM)
HONEST.XRP1 (RIPPLE)
NOTE: The HONEST.BTC backed MPA's are unique in the Bitshares ecosystem as they are the only MPA backed MPA's on the DEX. In this regard they are an exotic, experimental financial instrument.
You should be on a linux box with latest python version installed (3.7 or better).
First, perform these commands:
sudo apt-get update
sudo apt-get install pkg-config
sudo apt-get install libffi-dev
sudo apt-get install libsecp256k1-dev
You will then need to manually pip3 install the following dependencies (sorry no setup.py yet):
pip3 install requests
pip3 install cfscrape
pip3 install psutil
pip3 install websocket-client
pip3 install ecdsa
pip3 install secp256k1
Then clone the repo, be sure to include the empty /pipe/ folder! It will be used for text pipe inter process communication.
Next, in terminal, navigate to the folder containing pricefeed_final.py and run it:
python3 pricefeed_final.py
On your system, you may need to specify the python sub-version explicitly, like this:
python3.8 pricefeed_final.py
Then press Enter 4 times to skip publish, jsonbin, sceletus, and cancel functionality for now. Just confirm a demo works and you have all dependencies loaded. Once it is loaded; it takes about 3 minutes, exit the script:
ctrl + shift + \
to set up www.jsonbin.io functionality:
config_api.py will need the configuration dictionary values updated for jsonbin: key: and then the script saved. You get your key at www.jsonbin.io in the api keys tab, after signing up for their service. After installing the key, run the jsonbin.py script ONCE in the terminal with the command:
python3 jsonbin.py
The script will print a BIN ID. Next, install the id you just generated in the config_api.py script where it belongs as the jsonbin: id:; just under where you just installed the jsonbin: key:.
Then you can now test the jsonbin functionality of the pricefeed_final.py script. In terminal:
python3 pricefeed_final.py
Press y + Enter when prompted at startup by the jsonbin question. For all other question, just press Enter to skip the other functions for now. pricefeed_final.py will now use the jsonbin.py with the BIN ID you installed in config_api.py as a module to upload your data matrix for the public to see.
To view your jsonbin and ensure everything is working correctly, visit:
https://api.jsonbin.io/b/<your_bin_id>/latest
(be sure to install your bin id where it goes in the link)
In config_api.py you have a place to store this web address marked jsonbin: url:; this is not strictly necessary, but you should at the very least bookmark your jsonbin in a web browser, to check up on it later. Be sure to include /latest on the end of the url, as the jsonbin will contain a historic copy of every upload you make. Without latest the url points to the first upload and will appear to not update.
Next, you will need to sign up at several forex sites to access their api data. Open the config_api.py file again. It contains several forex data site urls for you to visit and attain keys. Each of these sites provides FREE data, all you need is an email address. Install the keys into the dictionary provided, in their respective places; then save the file. Also, save your password for each site someplace safe.
Be sure to inform us in the HONEST mpa development room of your jsonbin id so we can add it to the announce thread at https://bitsharestalk.org/index.php?topic=32035
Finally, the pricefeed script for the HONEST mpa's provides additional functionality called SCELETUS. This aspect of the script performs a dust quantity wash trade once per hour to provide a historical chart reference rate. Each price feed producer is expected to assist with this process as a marketing tool to display the accuracy of our pricefeeds over time. The annual blockchain transaction cost of these operations is expected to be less than $10. Each user has been assigned markets to sceletus. Open config_sceletus.py to find the markets assigned to you. Edit the uncommented return statement accordingly with the commented out statement assigned to you, then save the file. You will also need to manually purchase or borrow about 100 BTS (currently $3 value) of each instrument you've been assigned to sceletus to enact the buy and sell wash trade. It should be noted both the buy and sell will be performed by one account.
You are now ready to deploy live. Run pricefeed_final.py in the terminal. Choose y + Enter for all four initial questions asked by the script.
NOTE: You should certainly familiarize yourself with the scripts provided at this point
you are about to enter your private keys which provide COMPLETE ACCESS TO YOUR FUNDS
you SHOULD PERSONALLY ENSURE that you have read, understand, and trust the source code
