OCEAN is virtue signaling and hiding that miners who spamfilter are free riding on miners who don't. DATUM is not open source (source, koob: #978071)

and

"Unfortunately, OCEAN’s documentation for DATUM is limited, so most of the information surrounding how the protocol works is still shrouded in a bit of mystery. We’ve done our best to parse the differences between DATUM and Sv2 using the limited documentation we have and input from developers, but we will have a better understanding for how DATUM works under the hood if the OCEAN team fleshes out the details."

Okok, am I cherrypicking this to make lukejr look bad?

"it appears that the mining pool has no ability to deny a miner’s template since, with DATUM, miners only share merkle branches with the pool and not specific transactions (although we won’t know for sure until OCEAN releases more complete documentation"

If true, and I think it is true, then no I am not cherrypicking.

DATUM can't know transactions, so how can they pay out fairly when some miners filter spam and some don't?

yes lukejr is an idealist, but he's also not being honest. probably including not being honest with himself. It doesn't matter. Stratum v2 doesn't need ocean and doesn't need DATUM, and other mining pools (DMND, same thread as this) are leveraging this to make fair payouts with no free rides.

contrast with DMND's SLICE payouts:

"SLICE divides the blocks into two parts, the block subsidy and the fees. The block subsidy is distributed with the classic PPLNS method, based purely on the amount of hashrate you contributed inside the lookback window. On the other hand, the transaction fees are distributed according to both the hashrate contributed, and the financial value tied to that hashrate. The fee portion is what the Job Declarator in the Stratum V2 helps miners decide, that’s why SLICE can also be called PPLNS+JD." https://blog.dmnd.work/understanding-slice-pplns-jd/

Idealistic miners who care enough about censorship to want to control their block templates, but don't give a fuck about spam, are going to mine on DMND, not OCEAN.

These miners -- anticensorship but not antispam -- are the future of bitcoin. Not lukjr's spam filterers.

tldr stratum v2 with PPLNS+JD, versus DATUM the next bitcoin policy war.

my prediction: PPLNS+JD will win, even though it's a terrible name, because bitcoin is ferengi and when in doubt ferengi will ALWAYS TAKE THE MONEY.
