Bitcoin nearly split in two. On BIP110 activation day, a chain split actually happened — and almost nobody noticed. Coinjoined Chris (Seedor, Bitsurance) joins me to break down what BIP110 really was, why it was dead on arrival with under 6% real node support and near-zero hashrate, and what it teaches us about how consensus in Bitcoin actually gets decided. We go deep on fake pubkeys, OP_RETURN limits, relay policy vs consensus, the OP_RETURN spam wars since 2023, mining pool centralization, and why the "economic node" — not one-node-one-vote — is what really matters. If you mine Bitcoin but never think about what your hashrate is actually securing, this one's for you.

Curtailing your mine can cost you more than running it. Dan Lawrence, CEO and co-founder of OBM, started mining in a garage in Maryland in 2017 and built Foreman to stop driving an hour to reboot machines. Today Foreman turns Bitcoin miners on and off based on power prices, profitability and grid stress. Now Dan is building Vantage, a platform that reads the utility meter every 10 seconds and shows miners what their power bill really looks like.

Public Bitcoin miners shed about 75 EH/s in the first half of 2026, roughly $1.5 billion worth of mining hardware, as their power moves to AI. In this NEWS episode, Jesse breaks down who is leaving, where the hashrate is going and what it means for the miners who stay.
Cheap power means nothing if the government turns against you. Giannis Andreou, CEO of Bitmern Mining, started hosting Bitcoin miners in the UAE on agricultural power below 6¢/kWh, was forced out when the government banned that power, moved to Ethiopia, and is now watching the same story repeat as the Ethiopian government takes over mining and large operators pack up and leave.
Texas is ending 4CP. The incentive that saved flexible miners roughly $50,000 per MW per year is likely in its final season, and ERCOT is moving toward 12CP by 2028. Haley Thomson, Director of Energy at Luxor, explains what that means for Bitcoin miners and who ends up paying for the grid.Haley breaks down how 4CP actually works, why firm loads are pushing for change, and how 18+ GW of new battery storage has compressed capacity prices across ERCOT. We also cover why Bitcoin mining is close to the perfect grid-balancing load, how batteries and miners compare as grid assets, and how Luxor performed what's likely the first 4CP curtailment of GPUs in ERCOT.We also walk through the Luxor Energy dashboard live, from tracking load against breakeven to iMiner underclocking, 4CP buffer settings and what it really costs to be online during a peak. At the time of recording, 4CP season 2026 was likely already over.This episode is not sponsored by Luxor. Nothing discussed is financial advice.
