OCEAN’s DATUM protocol, developed by Jason Hughes, enables Bitcoin miners to construct their own block templates while collaboratively sharing variance across a decentralized network of independent mempools and solo operators. By distributing rewards strictly by proof-of-work through the TIDES system, DATUM eliminates the “invisible FPPS tax” that erodes miner revenue in centralized full-pay-per-share models. As Mark Artymko, OCEAN President, wrote for Mining Disrupt Magazine, “DATUM proves that mining does not need to choose between [decentralization and predictability].” At 12% network adoption, monthly working-capital reserves drop 73%; at 50%, the reduction reaches 86%. The result empowers smaller pools to compete without massive balance sheets, fostering stable, sovereign mining operations and reinforcing Bitcoin’s core promise of distributed control.

The Tech Buzz reports that OpenAI and Google have imposed strict limits on free access to their flagship AI tools amid surging holiday demand, marking a shift toward monetization in the artificial intelligence sector. OpenAI reduced free Sora video generations to six per day from unlimited, while Google trimmed Nano Banana Pro image creations to two daily from three, citing overwhelmed servers and escalating compute expenses. This rationing reflects a broader industry pivot from aggressive user acquisition to sustainable revenues, as infrastructure strains reveal the high costs of generative AI, each Sora video alone devours dollars in GPU resources. Bill Peebles, OpenAI’s Sora lead, candidly stated on Twitter, “Our GPUs are melting,” underscoring the hardware pressures without hinting at relief. Google similarly cautioned that limits “may change frequently and without notice,” per 9to5Google observations. As AI matures, metered access promises stable scaling and real revenues, now demanding that heavy users pay to play, thus preserving computing assets.

Melissa Heikkilä reports in the Financial Times that China has surpassed the United States in global downloads of open artificial intelligence models, capturing 17 per cent market share against America’s 15.8 per cent, according to a joint MIT and Hugging Face study. Beijing-backed laboratories such as DeepSeek and Alibaba’s Qwen dominate by releasing powerful, fully modifiable models on rapid weekly cycles, enabling developers worldwide to innovate freely despite restricted access to cutting-edge chips and training. Wendy Chang of the Mercator Institute notes, “In China, open source has been sort of a more mainstream trend than in the US,” while Shayne Longpre of MIT describes the approach as “paradigm shifting.” This open strategy accelerates adoption, empowers start-ups and researchers, and positions China at the centre of an increasingly decentralised AI ecosystem, promising broader technological sovereignty for nations and individuals seeking alternatives to closed American systems.

In an independent bitcoin markets analysis Nima reports that Nasdaq’s International Securities Exchange has proposed quadrupling position limits on options for BlackRock’s iShares Bitcoin Trust ETF, IBIT, from 250,000 to one million contracts, a move demonstrating the explosive institutional integration of bitcoin into traditional finance. This adjustment, filed with U.S. regulators, would align IBIT with premier ETFs like SPY and QQQ, enabling robust hedging, yield strategies, and innovative structured products amid 2025’s surging volumes and an $86.2 billion market cap. Analyst Adam Livingston of Bitcoin For Corporations observed, “This is the moment every banker secretly feared,” adding, “You don’t scale options by 40x unless you know demand is about to detonate.” The announcement ignited a swift market surge, with bitcoin options open interest leaping $4 billion to $62 billion in a day, propelling prices toward the high five figures, signaling near boundless potential for future inflows.
