delay the publishing of completed trades #1751
Description
the credit for the original idea in the Haveno Matrix room goes to @monerobull.
published data on completed trades already randomize/spoof the date of the trade. however, an active adversary that logs messages passing through the Haveno network can date completed trades with a high accuracy.
instead, this data could be published either...
- in regular or random batches, or
- per trade with independent random delays.
in either case, there is an implementation gotcha: the date of the delayed publishing must be greater than the randomized date(s) of the trade completion(s).
in this model, the network's admins and arbitrators could still know the true date of completion, but at least it wouldn't be public. presuming that admins and arbitrators are rational and aren't motivated by incentives external to the protocol, they are incentivized to keep this data confidential.
ideally, this data would be broadcast by the trading parties, but there is no guarantee that either of the parties will be online at a random later date to perform this task.
