And yes, I understand how demand for such services makes sense, and I do not fault you for pursuing them. But they are a threat, and I think the Bitcoin ecosystem should think hard about how to avoid their emergence I appreciate your response/interaction/opinion. I do believe you come to your position from your belief on what is in the best interests of Bitcoin, and I respect that. I realize that you don’t know me, and I can only say that my position is also established with the same intentions. With that said, I don’t think these types of services are a threat at all. I think they are essential to a healthy mining network where miners can have some control over a portion of their future revenue streams, especially in the greatly reduced subsidy era we are about to enter. And, I think the lack of a futures/forward market for blockspace is a major inhibitor to adoption and usage. Its hard to build a business where access to block space is a necessity without any visibility to the future. I believe this can be done in a manner that provides openness and transparency, and it would also give us for the first time visibility to future demand and pricing and I think that will be valuable to the enter ecosystem. Again, thanks for the reply.

The product/service I am working on would be public and anyone could participate. By publicly-enforced I literally mean deals enforced by the public, i.e., the Bitcoin network, where anyone is free to participate without needing to ask anyone for permission (e.g., I could imagine some hypothetical mechanism to buy futures of block space directly, as part of Bitcoin's network rules). This is in contrast with what I think you're referring to, a business deal, known to the public or not, that is enforced by parties knowing each other, and having legal agreements between them, or at least some means of legal recourse. The point is that revenue streams for miners that rely on them being identifiable real-world parties hurt permissionless of entry to the mining market, as they'd either need to build up their own contracts with block space users (where a new small-hashrate miner would be in a bad negotiating position), or join a conglomerate of miners that handles these contracts jointly - requiring asking the conglomerate for permission. A world in which there is no ability for users to have some level of certainty about access to future blockspace and the cost of that blockspace is not one that, imo, can scale to the levels that I believe we all hope to attain. Blockspace can/should act like any other commodity (think corn or soybeans) in which sellers (miners) mitigate risk and lock in long term revenue streams, and consumers (users) can guarantee their future access and the cost of that access. Blockspace acting as purely a real-time, spot market is not one that I feel is capable of scaling to global levels.
