After a lot of criticism that came Ocean's way in the beginning, the team over there has indeed shown the world that, truly, they're users of the bitcoin protocol that would deploy capital to acquire hardware to foster Ocean's vision as to what true sovereign mining is, and should be.
What was laughed at as a joke initially, has grown from <1 Eh/s to ~4Eh/s in about a year. One can only be optimistic about the development, as the company in question recently just launched DATUM, a way to further foster their vision of sovereign mining. Can't wait to see the TIDES game theory playout, as it's still the best payout scheme available today.
In Summary, Ocean's continuing to redefine what sovereign mining is all about while still accumulating hash-rate from low-time preference lovers of the protocol, and maintaining TIDES payout scheme remains the best compared to FPPS & PPLNS.
