In an address at the BCVC Summit, Federal Reserve Governor Stephen Miran argued that stablecoins have become “an established and fast-growing part of the financial landscape,” emphasizing their growing role in global dollar access and the potential monetary-policy consequences of their expansion. Citing research and internal Federal Reserve estimates, Miran said stablecoin reserves, mandated under the new GENIUS Act to be backed one-to-one with safe, liquid dollar assets, could fuel between $1 trillion and $3 trillion in new demand for Treasury bills by decade’s end. He warned that this influx of foreign capital may operate like a “global stablecoin glut,” echoing the early-2000s saving glut and exerting long-term downward pressure on the neutral rate. While noting systemic risks and adoption uncertainties, he presented an optimistic case for incorporating stablecoins into policy models as the digital asset industry continues to mature.

Nunchuk announced “Nunchuk 2.0,” a major upgrade introducing what the company calls the industry’s first assisted inheritance solution with an autonomous, on-chain failsafe. They explain that Bitcoin inheritance has long forced a choice between custodial convenience and self-sovereign resilience, but the new protocol combines guided support with a network-enforced guarantee. “Nunchuk 2.0 eliminates this compromise,” the team writes, citing a Miniscript-based architecture and timelocks that shift vaults from a 2-of-4 quorum pre-expiry to a 1-of-3 autonomous spend path after expiry. The design aims to bolster the bitcoin industry’s structural resilience by reducing reliance on any single provider, while preserving privacy through zero-KYC operations. Upcoming features, such as automated key rotation, flexible timelock management, and estate-planning compatibility, position Nunchuk’s Honey Badger platform as a maturing alternative for securing multigenerational Bitcoin holdings.

Apple introduced Digital ID, a new feature in Apple Wallet that lets U.S. users create a ‘secure’, device-stored identity using information from their passport. The company says the tool offers “the security and privacy of iPhone or Apple Watch,” with encrypted data, on-device storage, and biometric authentication. As reported in Apple’s release, Digital ID will debut in beta at TSA checkpoints across more than 250 U.S. airports, expanding access for travelers who lack REAL ID-compliant documents. Users add the ID by scanning their passport’s photo page and embedded chip, followed by a selfie and motion-based verification. Apple stated that it cannot see where IDs are presented, highlighting their focus on privacy-preserving design aligned with broader trends around user-controlled credentials. The company plans additional use cases, such as age and identity verification in apps and businesses, as adoption scales.

Ars Technica’s John Timmer reports that the year’s end has brought a flurry of incremental but meaningful advances in quantum computing, underscoring the sector’s steady march toward scalable error-corrected systems. IBM confirmed it has fabricated its new Loon and Nighthawk processors, shifting to a square nearest-neighbor architecture and introducing long-distance connections essential for future logical-qubit error correction. The company also validated a real-time error-identification algorithm on an AMD FPGA and opened a GitHub repository to benchmark quantum and classical algorithms, a move aimed at clarifying pathways to verifiable quantum advantage. In the trapped-ion sub-segment, IonQ announced record two-qubit fidelity above 99.99 percent, enabled by a method that reduces cooling steps and accelerates operations. Quantum Art, meanwhile, unveiled an Nvidia-supported compiler for its multicore, cluster-based trapped-ion approach. Together, the updates point to accelerating innovation and a maturing industry.
