TODAY’S TOP STORIES

⛏️ Block & Dorsey Unveil Game-Changing Modular Bitcoin Mining Rig

Jack Dorsey's Block just unveiled Proto Rig, a revolutionary modular Bitcoin mining system designed to last a decade, rather than the usual three to five years. The upgradeable design slashes repair costs by 15-20% per cycle and cuts maintenance time from days to seconds with tool-free hashboard swaps. Paired with free open-source Proto Fleet management software supporting Stratum V2 protocol, Block is democratizing mining infrastructure while delivering 1.5 times the power density of legacy systems.

🏦 Bessent Clarifies: No BTC Buying, But Reserve Still Growing

Treasury Secretary Scott Bessent sparked confusion by saying the US won't buy more bitcoin, then quickly clarified on social media that Treasury remains committed to exploring budget-neutral pathways to acquire more BTC. The strategic bitcoin reserve, built on $15-20B in seized criminal assets, will stop selling confiscated Bitcoin and continue growing through alternative acquisition methods rather than direct purchases.

⚡ Tether and Lightspark Turbocharge Bitcoin Lightning Wallets

Tether just turbocharged its open-source Wallet Development Kit by integrating Lightspark's Spark Bitcoin Lightning infrastructure, enabling developers to build non-custodial wallets with instant, low-cost Bitcoin and USDt payments. The integration removes complexity from self-custodial wallet development while supporting Tether's vision for AI-driven autonomous agents that can transact independently. This powerful combo aims to democratize Lightning payments across mobile, desktop, and web applications without relying on custodial services. Tether
