I need to point out that you're being unfair to Ocean here: with their <1% =
hash
power it's damn near impossible for them to reorg blocks. The reason is bec=
ause
if there are two blocks at the same height, Bitcoin Core accepts the first
block seen.
Thus if Ocean wants to reorg a "spam" block out, they need to find not just
one, but two blocks in a row before any other miner finds one. The probabil=
ity
of that happening is (very) roughly 1% * 1% =3D 0.01% per attempt. Given th=
at
blocks are worth ~$300k these days, you're asking them to spend tens of
millions of dollars worth of hash power just to reorg out a single block.
It's not going to happen.
