Thanks Luke,

I like this idea very much -- perhaps adding gateway reputation (as Gilbert suggested) as the value point.  So the more a gateway is found to be unreliable (crashes too many times, tries to cheat, etc), it lowers the reputation score of the gateway.

Then the gateway election protocol could factor-in this reputation score.

Subject: [Blockchain-interop] Interesting paper when truthful behaviour may not be guaranteed

Hi all,

This is the paper I mentioned in the meeting: https://eprint.iacr.org/2018/489

Placing two gateways (with access to the same ledger but run by different parties) into a game against each other to guarantee (if economically rational) that the data returned is correct.

Regards,

Luke
