[bitcoin-dev] On the Nature of Miner Advantages in Uncapped Block Size Fee Markets

[Daniele Pinna]

I'd like to submit this paper to the dev-list which analyzes how miner
advantages scale with network and mempool properties in a scenario of
uncapped block sizes. The work proceeds, in a sense, from where Peter R's
work left off correcting a mistake and addressing the critiques made by the
community to his work.

The main result of the work is a detailed analysis of mining advantages
(defined as the added profit per unit of hash) as a function of miner
hashrate. In it, I show how large block subsidies (or better, low mempool
fees-to-subsidy ratios) incentivize the pooling of large hashrates due to
the steady increasing of marginal profits as hashrates grow.

The paper also shows that part of the large advantage the large miners have
today is due to there being a barrier to entry into a high-efficiency
mining class which has access to expected profits an order of magnitude
larger than everyone else. As block subsidies decrease, this
high-efficiency class is expected to vanish leading to a marginal profit
structure which decreases as a function of hashrate.

This work has vacuumed my entire life for the past two weeks leading me to
lag behind on a lot of work. I apologize for typos which I may not have
seen. I stand by for any comments the community may have and look forward
to reigniting consideration of a block size scaling proposal (BIP101)
which, due to the XT fork drama, I believe has been placed hastily and
undeservedly on the chopping block.
