If you run the “sane mempool fork” where the higher block health you have, the less spam you include, you’ll see that Ocean have by far the greatest average block health (over 75%), where miners like MARA have around 40%.
Some more details on Ocean's anti-spam:
- the majority of blocks found by Ocean are mined using DATUM, where the miner can provide its own template, so Ocean's policy doesn't matter at all. It would be interesting to have some stats on how much of the Ocean DATUM blocks are anti-spam, I don't know, but my impression is that there are spam-filtered as well as non-filtered blocks there
- for the non-DATUM blocks, i.e. when you as a miner simply use the block template provided by Ocean: even there there is choice for the miner. Probably many use the default setting (which filters a lot), but no-filter option is also available. They all have 2% fee. See https://ocean.xyz/docs/templateselection
I'm very excited about Ocean, and about their growth! Their novel way of coinbase-payout, being PPLNS, and offering a relatively easy own-template solution are all important.
I'm not sympathetic with their filtering stance (and I'm not using filtering), because I consider it ineffective (as long as there are even just a few % of miners who don't filter), but that's not the main point in this post.

Here it is. I researched this a couple of months ago.
My mistake about the 40% block health. It’s around 59%.
Of course, and that's no surprise having in mind Ocean's strong filtering stance. But if you look at individual blocks found by Ocean, you can see that some blocks are not filtered. Probably by miners who like Ocean's payout method, but don't like filtering. And that makes sense.
E.g. if you look at blocks with the tag "OCEAN.XYZ >NiceHash" or "OCEAN.XYZ >Peak Mining" or "OCEAN.XYZ >Penguin", those look like created by a node with a mempool consistent with the majority of the miners and the nodes (i.e., Bitcoin Core).
Yes, and I have no problem with that. I may not like it, but it’s their choice.
