this won't be lasting only for "one year" given current difficulty and generously assuming hashrate of the whole ocean pool (~3% of current hashrate): - bip chain will mine 1 block every ~5.5 hours (btw if we take current signalling it is ~1 block per day) - the "one year" period is measured in blocks: 52416 blocks - diff adjustments will happen every 2016 blocks = ~466 days (for first adjustment and it will require multiple adjustments to achieve 10 minutes block interval) - this will lead to a ~2.5 years period until 52416 blocks have passed * assuming constant hashpower of 3%. bip miners have to keep up mining through the first adjustment periods
