Witness Essentials: Pricefeed v1.0.2

---

Witness Essentials: Pricefeed received an update, which includes:

• Replaced temporary dsteem-hf20 package with dsteem
• Changed config.json variableEXCHANGES from an array to object to simplify the toggling of specific exchanges (true => false)
• USDT Exchanges have been added to the config.json for simplified management
• USDT conversion variable has been renamed
• A small bug has been fixed which would prevent the publishing of pricefeed in case of no private signing-key while still having a valid active-key

Update Information

Since a lot in the config.json has changed, you can either remove/move the existing config.json and copy/paste from config.example.json what you need into the new one, or vice-versa.

Regarding the bug fix:

Essentially the active_key was missing as a parameter and a variable (set_properties), which is needed for the code to know whether it should sign with private signing-keys (new feature in HF20) or via active-key, wasn't set correctly.

See below for the code.

# before
transaction_signing_key = essentials.choose_transaction_key(_g.CURRENT_SIGNING_KEY, g.config.SIGNING_KEYS)
... more code
set_properties = true

# after
transaction_signing_key = essentials.choose_transaction_key(_g.CURRENT_SIGNING_KEY, _g.config.ACTIVE_KEY, _g.config.SIGNING_KEYS)
... more code
set_properties = transaction_signing_key !== _g.config.ACTIVE_KEY

All right, that's it for the much-needed update (1.0.1 was released 4 months ago), but at least over all that time, the pricefeed worked flawlessly. :)

So, I hope my fellow witnesses find this useful and if there are any questions, let me know.

All the best,
Wolf
