Could be, it is not very relevant what he is referring to, I just analyzed the message. Core 30 opens up major attack vectors as well. But to say "the mining pool centralization problem is already solved with Datum - it just needs much wider adoption", is like saying "the MoE problem is already solved with Bitcoin/Monero - you just have to get people to use them". Inside OCEAN, DATUM is now the default; network-wide it's still ~1% or less. OCEAN is only about ~1% of total Bitcoin hashrate (order of magnitude; varies over time). If ~65–94% of OCEAN’s hashrate is on DATUM, that implies ~0.6–0.9% of the network hashrate is mining with DATUM today. Stratum V2 is available at Braiins Pool and OCEAN/DEMAND’s pool, plus scattered tests elsewhere, but network adoption remains ~1% of hashrate or below. So mining pool centralization isn't a solved problem for now. Solvable problem, but not solved.
