The fee market would be more efficient if there was a possibility to buy futures. If I know my transactional demand for my business model, it should be possible to lock in a price for that.
Do miners offer such future block space? Is there a secondary market for those futures? It would be incredibly helpful for others to see these future rates.
How would that work? You would book the ability to make a txn between two block heights for a certain sat/vB?
Yeah, basically. I guess it would be a contract based on calendar days and not block heights. Bigger miners could offer more with more granularity.
It would have to be from a miner or pool with a large enough share of the hash power to actually be confident in finding blocks in a given range. Unless a coordinator buys futures from many different miners to give the same effect.
It would definitely drive centralization but as you say, it would not have to be the miner or even the pool that offers such a service. The service would have to get access to some blocks per day at least to make sense but that's like 2% of the hash rate. You don't need some 50% for that.
Interesting idea
