This post presents two additional ways of understanding our protocol, which are at opposite ends of the complexity and accessibility. A state machine and a comic strip. We hope some might find this helpful and if not, give us feedback to help us improve them.
As our team grew over the last months, we had to explain our protocol a few times and realized that only our resource to defer to was the whitepaper which, while being technically accurate, is not the most accessible or condensed. This was especially true for the many ways in which an assessment can go awry, such as assessors failing to complete a certain stage or not showing up in the first place.
Also, our implementation of the protocol on the ethereum blockchain introduced certain extra-steps, which are not specified in the whitepaper, but will affect the user experience in our app 1.
So we created two other resources:
Let's have some fun first and look at the diagrams!
This first one gives a general overview how an assessment goes down:
The other two are to explain what happens afterwards. Here's how we find the final score:
But what happens if there is a draw? Or if there is no agreement at all? We could just answer in text or take it as an excuse to make some more diagrams:
Next, we have a diagram that explains how an assessors position inside or outside the winning cluster and their relation to the other assessors affects their payout:
The second diagram explains the same thing but condenses the 3 steps from above into one:
If you still have questions (and a faible for state machines), then check whether this (somewhat intimidating) diagram answers them for you.
This is because every state change on the ethereum blockchain has some costs associated to it, the so-called gas-costs. Gas can be thought of as the fuel of the blockchain. Every state change consumes at least a little bit of it and without it, one can not only read from the chain, but not write to it. Among other this is to prevent trolls from spamming (image every spam-mail would cost a cent!) and to pay the people who keep the chain running (aka the 'miners') by processing the incoming transactions. That is why every internal state change of our contracts need to be triggered from the outside and we can not automatically cancel timed-out assessment or give out refunds.↩
