[Bitcoin-development] User vote in blocksize through fees

[Stephen]

While this idea is theoretically interesting because it involves many stakeholders, rather than just miners, I think in practice this would not work very well. Users don't want to worry about this kind of technicality, they just want to be able to make a transaction and have it be processed. 

In addition, while this gives stakeholders some weight with the fees they supply, these fees are marginal compared to the block size subsidy. If this proposal were actually implemented, I think miners would vote for whatever they think is best, and users would not contradict them with their votes to ensure a fast confirmation time. Users are incentivized to be in agreement with miners because the miners provide them with the confirmations they need, but fees do not provide a great incentive for miners to be in agreement with users, and likely won't for some time. 

Best, 
Stephen
