Klerosboard Graph

This is the repo where you could find the backend of klerosboard. The aim of this graph deployed in thegrap.com is to track the evolution and transactions in the Kleros Courts.

Content

[] means not implmented; [!] means implemented but with bugs or not reviewed; [x] means already implemented;

Global counters (KlerosCounter)

The graph have global counters to track different properties and metrics of interest of all the courts. This counters are: [x] Courts count

Smart Contracts

All the tracking of this grpah will be done checking the events of the KlerosLiquid smart contract, and the Policy Registry contract.

Kleros Liquid events of interest:

setStake

When a juror stake or unstake pnk in some court. This event returns the current stake and the total current stake (total is the stake of the juror in all the subcourts). When this event is emmited, some entities should be created/updated. First of all, there is a setStake entity that will record this event, to have all the history of all the stakes. For this entity it's needed the Juror entity, that should be created or loaded to link the setStake event with the juror. Also, this juror entity should be updated with the subcourts where the juror is or has staked, updated if it's a active juror and the totalToken staked. Then, a CourtStake entity should be created or updated. This entity has the last setStake event of this juror in this specific court. In addition of this, some counters has to be updated. Each court has it's own counter of active jurors, so if this is a new juror, the active juror count of this court has to be increased by one, if the juror it's unstaking from the court, the counter should be decreased. This counter has to impact in all the parent courts also. Each court has a counter of the amount of tokens staked, this has to be updated and also in the parent courts. Last, the global counter (KlerosCounters) shall be updated if it's needed to take into account if this jurors it's a new active juror or it's a new inactive juror.

newPeriod

When a dispute changes to a new period. The posible phases are: {0:evidence, 1:commit, 2:vote, 3:appeal, 4:execution}. [MORE INFO NEEDED HERE]

AppealDecisionEvent

Event raised when a dispute is appealed [MORE INFO NEEDED HERE]

draw

Emitted when a jurors is drawn in a case. A draw entity it's created, but also a vote entity. This vote entity will track when a juror cast a vote.

TokenAndETHShift

Emmited when a juror win or lose tokens and ETH from the case. not implemented yet

KlerosLiquid functions calls of interest:

createSubcourt

Besides is not the best performance to track functions calls, is the only way to track the creation of a new subcourt. Also the courts could be created when a dispute it's created and the court it's not in the subgraph yet (due to colision events between createSubcourt call and createDispute events). This it's more a subgraph technisism rather than a blockchain issue. In the practice you can not raise a dispute in a court that doesn't exist, but for how the subgraph read the blockchain, this situation can be raised.

ChangeSubcourtTimesPerPeriodCall

Change the timesPerPeriod field of a court

ChangeSubcourtJurorsForJumpCall

Change the jurorsForJump field of a court

ChangeSubcourtJurorFeeCall

Change the JurorFee field of a court

ChangeSubcourtAlphaCall

Change the alpha field in a court

ChangeSubcourtMinStakeCall

Change the minStake field in a court

PolicyUpdate

Emitted when a policy is updated. Has the subcourtID and the policy.A policyUpdate entity it's created to store this event. If it's the first policy for this court, the entity should be created, if not, just the policy and other fields should be updated. In addition, the court entity should be updated so the last policy is linked.
