Technical
(Blockchain->Technical)
Proposal
Change the alpha parameter to 50%
Rationale
The current parameters (specifically fees and minimum stake) of the technical court are based on those of the token listing court, with the idea being that the cases are of comparable difficulty although requiring somewhat different skills. However, the alphas were set differently - whereas the alpha of token listing is 50%, the current alpha in technical is 32.5%. Consequently the deposit lost in the case of an incoherent vote in techical is low enough relative to the arbitration fees received that there is a risk of lazy voting attacks. (See https://github.com/kleros/research-docs/blob/master/klerosfees12fev2019.pdf pages 2-3 for analysis and constraints on when lazy voting attacks are potentially profitable compared to honesty.)
