TODAY’S TOP STORIES

🏔️ New Hampshire Blazes Trail with Bitcoin-Backed Bonds

New Hampshire’s Business Finance Authority just approved a $100M municipal bond backed by BTC, marking the first of its kind in the US. Businesses can secure loans with over-collateralized BTC held by BitGo, avoiding taxpayer risk while unlocking capital without selling their sats. Designed with Wave Digital Assets and Rosemawr Management, the bond links Bitcoin to the $140T global debt market, with fees and gains funneled into a Bitcoin Economic Development Fund. Atlas21

🛡️ Bitcoin Core Passes First Security Audit with Flying Colors

Bitcoin Core just aced its first independent security audit, with French firm Quarkslab finding zero serious vulnerabilities after examining 200,000 lines of code over 104 days. The auditors called it the 'most mature and well-tested' codebase they've evaluated, identifying only two minor issues with no impact on consensus or security. This clean bill of health comes as Bitcoin Core faces criticism over not censoring non-financial blockchain data. Cointelegraph

🇦🇪 Abu Dhabi Sovereign Fund Triples Down on Bitcoin ETFs 

Abu Dhabi’s Investment Council more than tripled its stake in BlackRock’s iShares Bitcoin Trust to nearly 8M shares in Q3, worth about $518M before the market dip. Calling BTC ‘digital gold,’ the sovereign fund sees it as a long-term store of value alongside traditional assets. The move bolsters Abu Dhabi’s bid to become a global crypto hub, with other big players like El Salvador and Kazakhstan also stacking sats despite recent ETF outflows and price volatility.
