On the Stephan Livera Podcast, developer Jungly outlined why P2Pool V2 matters for Bitcoin’s future. The project aims to revive and scale the original P2Pool, a decentralized mining pool first launched in 2013, by addressing its technical bottlenecks. As Jungly explained, “the concern is…today [mining] is a bit more centralized,” with custodial pools controlling payouts and block construction. P2Pool V2 introduces a sharechain with uncle blocks to reduce orphan rates, compact block propagation to minimize latency, and atomic swaps to solve Coinbase output limits, allowing non-custodial payouts via Lightning or on-chain. Unlike Stratum V2 or DATUM, which still rely on centralized pools for payments, P2Pool V2 removes that control entirely. Jungly hopes to release an MVP by early 2026, with a target of reaching 1% of network hash rate. If successful, the effort could significantly strengthen mining decentralization and resilience in the bitcoin mining industry.

Brian Albrecht, writing in Economic Forces, argues that new U.S. tariffs will provide a rare, testable moment to pit standard supply-and-demand theory against Isabella Weber’s “sellers’ inflation” framework. Under textbook economics, tariffs are a supply shock: prices rise, quantities fall, and profits compress as firms absorb higher costs. Weber, by contrast, contends that “tariffs can once more give companies cover to raise prices without losing market share,” enabling firms to expand margins through implicit coordination. The theories diverge sharply; standard models predict squeezed profits, while sellers’ inflation anticipates higher ones. Albrecht stresses the value of predictions made in advance: “The beauty of clear predictions is that they can be wrong.” The outcome will hinge on tariff-affected industries and any Federal Reserve response. If profits rise instead of falling, Weber’s theory could gain traction, forcing economists to rethink conventional views on cost shocks.

BitMEX Research weighed in on the ongoing debate over whether Bitcoin Core should remove the policy limit on OP_Return outputs, which are used to embed arbitrary data in the blockchain. While critics argue that larger OP_Returns encourage spam and undermine Bitcoin’s role as a financial network, the report stresses that miners are already incentivized to include any transaction that pays sufficient fees. Pointing to the Ordinals boom, with over 88 million inscriptions paying more than 7,000 bitcoin in fees, the authors note that “miners have received over 7,000 bitcoin in fees related to Ordinals,” and management teams welcome this as a revenue stream. They warn that if limits remain, miners could build private transaction pipelines, weakening the public mempool and pushing centralization. Removing the limit, they argue, better aligns incentives, keeps Compact Blocks functional, and acknowledges that spam prevention ultimately comes from fee competition, not policy guardrails.

Intel’s short-lived Blockscale chips are finding a second life in the hands of open-source developers. As Tom’s Hardware reports, Jack Dorsey’s Block has donated 256,000 Bonanza Mine (BZM2) ASICs — once marketed as a clean, efficient alternative to Bitmain rigs — to nonprofit collective 256 Foundation. The chips, representing up to 76 PH/s of aggregate capacity, will be split among four U.S.-based open hardware projects. While initially pitched at 580 GH/s with 23 J/TH efficiency, the donated batch is expected to deliver around 0.3 TH/s per chip at ~29 J/TH in DIY builds. “Getting the BZM2 chips into the hands of open-source developers is a noteworthy milestone,” said 256’s founder, Econalchemist, highlighting opportunities for inspection, modification, and repurposing. Beyond Bitcoin mining, applications could include home heating, renewable energy capture, and infrastructure experiments, signaling a more decentralized and flexible era for mining hardware.
