100 BitUSD to First Person to Publish a working Price Feed Script for Graphene

[bytemaster]

I'm still unclear on who will be publishing feeds for assets?  I was under the impression that this would be something workers would do.  Is this something I will be expected to do as a witness?  Not that I mind or anything, just looking for clarity.

Witnesses publish for the network.

/** Publishes a price feed for the named asset. * * Price feed providers use this command to publish their price feeds for market-issued assets. A price feed is * used to tune the market for a particular market-issued asset. For each value in the feed, the median across all * committee_member feeds for that asset is calculated and the market for the asset is configured with the median of that * value. * * The feed object in this command contains three prices: a call price limit, a short price limit, and a settlement price. * The call limit price is structured as (collateral asset) / (debt asset) and the short limit price is structured * as (asset for sale) / (collateral asset). Note that the asset IDs are opposite to eachother, so if we're * publishing a feed for USD, the call limit price will be CORE/USD and the short limit price will be USD/CORE. The * settlement price may be flipped either direction, as long as it is a ratio between the market-issued asset and * its collateral. * * @param publishing_account the account publishing the price feed * @param symbol the name or id of the asset whose feed we're publishing * @param feed the price_feed object containing the three prices making up the feed * @param broadcast true to broadcast the transaction on the network * @returns the signed transaction updating the price feed for the given asset */ signed_transaction publish_asset_feed(string publishing_account, string symbol, price_feed feed, bool broadcast = false);

We are looking for testers who will publish a BitUSD price feed in graphene.  You will need to be an elected witness to publish the feed.

You can either provide the script to an existing witness tester or become a tester yourself. 

Unfortunately there is little documentation on HOW to do this right now, hence the bounty.   Xeroc may be able to help.
