Hey mate, so good to finally meet you the other day! You're correct, with the way 73 has it at the moment, it's flawed (I've mentioned this to them a few times) in that their treasury just ends up with a terrible portfolio. For example, they had like 25% of the port being Checkerchain which was a dying subnet.
So 127 is 3 things. A cap raising construct, a VC like entity (which will generate profits in any dTAO market condition) and then the DaT. Everything would still work even if we didn't do a Liquidity Sink thing with the DaT. But in terms of how it will work, I'll come up with a ranking algo which ranks subnets based on a bunch of different metrics. There will be an easy dashboard/UI which shows all the discounts.
Let's say you have X alpha and there's a 10% discount attributed to it, you deposit $10k of X alpha into the DaT (which is locked up via smart contract for years and temporarily makes you a miner) and you will get $9000 of Astrid alpha. You can do whatever you want with our alpha. Dump sell it in one clip if you like. Not fussed as we will have a LOT of alpha buyback pressure generated from profits of the subnet trading etc. And the higher emissions, the more alpha we can absorb.
What you'll probably find is that the discount for a shit alpha will be like 50% or more. So it will disincentivise people to swap in bad alpha.
