Even without that confirmation seeded auctions are a very nice way to tie NBT to NSR. I dare say I haven’t seen a better concept for adjusting the NBT supply than seeded auctions - at least not if parameters are integrity, reliability, transparency, continuity.
Deriving information which side to seed (NSR or NBT) from the average liquidity situation allows establishing a framework that can adjust the NBT supply in an ongoing process.
With a little bit of scripting the effort for tier 4 multi signature custodians could be limited to signing a transaction once a day, each two days, once a week, whatever the cycle will be, with information about the side and the amount to seed being automatically discovered based on the liquidity situation.
Maybe this can be even automated to a degree with that the reputed signer system at BCE will work - tier 4 multi signature “reputed” signers operate bots that automatically seed the auctions. Their responsibility would be limited to verifying the bot function and private key management of the multi signature address.
There might be attack vectors that need to be considered and eliminated.
But as BCE is going to establish such an automatic signing system, there might be ways to adjust it for automating seeded auctions at Nu - once more a situation in which both Nu and BCE might profit both from something that was mainly developed for one of them.
