If someone is going to make a Bitcoin transaction and add a commi= +tment for zero cost, just by tweaking some Taproot public key, then it is a= + benefit for the network, because then it is possible to get more things wi= +th no additional bytes. Instead of doing "transaction-only", people can do = +"transaction+commitment" for the same cost, that use case is positive. +> +> But if someone is going to make a Bitcoin transaction only to commit thin= +gs, where in other case that person would make no transaction at all, then = +I think we should have some mechanism for "miner-based commitments" that wo= +uld allow making commitments in a standardized way. We always have one coin= +base transaction for each block, it is consensus rule. So, by tweaking sing= +le public key in the coinbase transaction, it is possible to fit all commit= +ments in one tweaked key, and even make it logarithmic by forming a tree of= + commitments. +> +> I think we cannot control user-based commitments, but maybe we should sta= +ndardize miner-based commitments, for example to have a sorted merkle tree = +of commitments. Then, it would be possible to check if some commitment is a= + part of that tree or not (if it is always sorted, then it is present at so= +me specified position or not, so by forming SPV-proof we can quickly prove,= + if some commitment is or is not a part of some miner Taproot commitment). + +You might consider implementing `OP_BRIBE` from Drivechains, then. + +Note that if you *want* to have some data committed on the blockchain, you = +*have to* pay for the privilege of doing so --- miners are not obligated to= + put a commitment to *your* data on the coinbase for free. +Thus, any miner-based commitment needs to have a mechanism to offer payment= +s to miners to include your commitment. + +You might as well just use a transaction, and not tell miners that you want= + to commit data using some tweak of the public key (because the miners migh= +t then be induced to censor such commitments). + +In short: there is no such thing as "other case that person would make no t= +ranscation at all", because you have to somehow bribe miners to include the= + commitment to your data, and you might as well use existing mechanisms (tr= +ansactions that implicitly pay fees) for your data commitment, and get bett= +er censorship-resistance and privacy. + +Nothing really prevents any transaction-based scheme from having multiple u= +sers that aggregate their data (losing privacy but aggregating their fees) = +to make a sum commitment and just make a single transaction that pays for t= +he privilege of committing to the sum commitment. + +Regards, +ZmnSCPxj + |
