About the Project

https://the-magic-frog.com
The Magic Frog is a Bot/Website utilizing the STEEM blockchain to reward participants for collaboratively telling a story. By submitting small pieces of text, that the community can vote on everyday, the story evolves and sometimes takes quite strange, funny or interesting turns.

The Magic Frog is currently available in English, French and German and more languages will follow!

Delegators get their share of the cake now!

I finally managed to finish an actually very easy task. Delegators, which are very important for the project to succeed, will be rewarded from now on, like everyone else, when a story ends. 20 % of the story pot will be reserved for delegators and distributed among them according to their delegation.

For the first french story, which is on the verge of ending it seems, and there actually are some delegators, it looks like this (at the time of writing):

Account: @grenouille
Total Delegations: 790.548 SP
Story Pot: 12.481 SBD <-- Increases the more delegated SP there is!
Delegators Pot: (20 %) 2.496 SBD

Delegator	SP	% of Total	Reward
@helo	500.523	63.31	1.580 SBD
@pnc	250.008	31.62	0.789 SBD
@orlandumike	25.002	3.16	0.078 SBD
@zonguin	15.015	1.89	0.047 SBD

For the english version, where I am still the only delegator, it looks like this:

Account: @the-magic-frog
Total Delegations: 502.016 SP
Story Pot: 27.399 SBD
Delegators Pot: (20 %) 5.479 SBD

Delegator	SP	% of Total	Reward
@mkt	502.016	100	5.479 SBD

Implementation

The update is really just one single commit: https://github.com/mktcode/the-magic-story-machine/commit/6c37ba7d4d787afc1391a2fe46c52fdf7185f407

Retrieving delegators:
https://github.com/mktcode/the-magic-story-machine/blob/master/helper.js#L78
I get the delegators from https://api.the-magic-frog.com/delegators?account=, which in turn gets them from https://helloacm.com/tools/steemit/delegators/

Updated rewards calculation:
https://github.com/mktcode/the-magic-story-machine/blob/master/bot.js#L51
As mentioned before, the delegators get 20% of the pot, thus decreasing the storytellers' rewards, which is now only 80 % of the total pot. This should be not a big issue as this update hopefully leads to more delegations, increasing the rewards again.

Transfer rewards:
This is quite straight forward.
Get total delegations: https://github.com/mktcode/the-magic-story-machine/blob/master/bot.js#L51
Calculate each delegator's percentage and share of the pot: https://github.com/mktcode/the-magic-story-machine/blob/master/bot.js#L111
Transfer: https://github.com/mktcode/the-magic-story-machine/blob/master/bot.js#L123

Added translations for transfer memo:
https://github.com/mktcode/the-magic-story-machine/blob/master/locales.js#L104
Of course delegators also get a localized "Thank you!", depending on what account they delegated SP to.

Other Changes
https://github.com/mktcode/the-magic-frog/commit/70529c16d3bdfe26fb2c922bc0cfab15f04ef3c4
Until now it was not possible to submit your own text, when you want the story to end. The text was just "The End!". Now you can submit text, as the last sentence in the story, and end the story at the same time, to start a new one.

And some minor fixed:

Next Steps

• write a "Call to Delegators" post! :D
• change server infrastructure
• stability improvements
• own account creation system
• write visibility task request on Utopian
• provide "closed" versions for schools
