Transmitter update: Introducing publish_feed command (using private signing keys)

Repository: https://github.com/emre/transmitter

Transmitter is a CLI tool for STEEM blockchain witnesses. It quickly allows you to enable/disable your witness or set some properties for the new witness_set_properties call introduced in Hard Fork 20. - announcement post

Transmitter got a brand new command, publish_feed, to publish STEEM's market price to the blockchain. (with v0.1.3)

After HF20, it's possible to feed this data with witness_set_properties operation. I have used that option instead of broadcasting a feed_publish operation since using witness signing keys instead of the active key is better and safer.

Before trying out that feature, make sure you have upgraded the app.

$ pip install transmitter --upgrade

Add WITNESS_ACCOUNT and SIGNING_KEY fields to the ~/.transmitter.config.json.

Example:

{
        "WITNESS_ACCOUNT": "emrebeyler",
        "SIGNING_KEY": "5...."
}

To update the feed:

$ transmitter publish_feed --markets poloniex,bittrex,binance


Shiny CLI apps, we need more of them!

How does it work?


  • It gets the average price of the markets you choose. Currently, only 3 markets (Poloniex, Bittrex, Binance) are supported.

  • You can select markets with the --markets x,y,z syntax.

  • It's possible to set price bias by using --peg_multiplier. Passing --peg_multiplier 2 will give you 1 / 2 on quote field. (%100 price bias.)

  • For the markets don't have a direct BTC/USD pair, I have used USDT alternatives.

Roadmap


  • Adding more market adapters
  • Auto exclude market price on some conditions. (Ex: Price pump in a locked market.)
  • Periodical call support. (Currently, if you need to execute it, you need to set a crontab entry, or use other schedulers.)

I will continue to develop transmitter to make it a great toolkit for witness operations. Let me know if you see any problem or have any feature ideas on project's issues page.

Thanks for the contribution, @emrebeyler! Cool to see you can now use witness signing keys (didn't even know that was a thing) instead of an active key with Transmitter.

Can't really give any feedback about the code as it's great as always. Keep up the great work you're doing for the blockchain!
