I could add a comparison to p2pool if you want, but bear in mind this is a
blog post designed to introduce a complex topic to a wide audience, not a
literature review of all possible designs and prior art.
In particular, while P2Pool and DCFMP share a goal (decentralize mining),
the approaches to them bear very little similarity as DCFMP is focused on
making the pooling a pure client side validatable function of the existing
chain, and not create a major risk to mining centralization with a reliance
on a new network running on top of Bitcoin. DCFMP also lacks the core value
prop of P2Pool which is higher resolution on share assignment.
Further, DCFMP's core innovations are Payment Pool and non interactive
channel based, something the P2Pool does not have, but could adopt, in
theory, to solve their payout problems[^note]. I still believe that making
a unified layer of networked software all miners are running on top of
Bitcoin in the loop of mining is a major risk and architecturally bad idea,
hence my advocacy for doing such designs as micro pools inside a DCFMP; It
would be possible to make the "micropools" run on a P2Pool like software,
the DCFMP allows for smaller P2Pools to aggregate their hashrate
trustlessly with the main DCFMP shares.
[^note]: for what it's worth, I was not familiar with p2pool very much
before I came up with DCFMP. The lineage of my conceptual work was
determinism, payment pools, and then realizing they could do something for
mining.
