Bitcoin developers have proposed an updated BIP 360, a draft soft fork introducing Pay-to-Tapscript-Hash (P2TSH), a new SegWit version 2 output type that mirrors Pay-to-Taproot (P2TR) functionality while eliminating the quantum-vulnerable key path spend. Authored by Hunter Beast, Ethan Heilman, and Isabel Foxen Duke, P2TSH commits solely to a tapscript tree's Merkle root, enabling script-path-only spends that resist long-exposure quantum attacks on exposed public keys. This addresses concerns over potential cryptographically relevant quantum computers deriving private keys via Shor's algorithm, offering users a proactive option for enhanced security without mandating network-wide changes. "We propose Pay-to-Tapscript-Hash (P2TSH), a tapscript-native output type that can be used in a quantum resistant manner," the authors state. By reusing existing Taproot code, the proposal minimizes implementation risks while paving the way for future post-quantum signatures, hopefully putting to bed ongoing quantum anxieties.

Independent researcher Brian Roemmele, writing in Read Multiplex, analyzed Anna’s Archive’s unauthorized 300TB backup of Spotify’s 256 million tracks, released late December, revealing streaming’s dystopian underbelly. His AI-driven exploration uncovered that 70% of tracks receive fewer than 1,000 streams, amid a surge in AI-generated content comprising 34-38% of new uploads, diluting human artistry. Key insights include users’ addiction to familiar hits, genre echo chambers, and emotional engineering toward upbeat escapism. Roemmele questions, “Is it the end of music?” highlighting commodification where algorithms prioritize virality over depth. The open music archive, while illicitly acquired, empowers opportunities for potential public stewardship in music and consumer research, and a potential renaissance for artists hoping to create authentically in the digital age.

JPMorgan Chase, America's largest bank, is in early discussions to offer bitcoin spot and derivatives trading to institutional clients, driven by surging demand from hedge funds, asset managers, and pension funds seeking compliant, liquid access through established institutions. According to Bloomberg, the review weighs client interest, risks, and evolving U.S. regulations that increasingly permit banks to intermediate in digital assets (i.e. opportunities to make money). No final decision has been reached, and the bank declined comment. This potential shift contrasts with CEO Jamie Dimon's historical criticism, yet reflects a pragmatic embrace of client freedom and market opportunities. Dimon recently stated, "I defend your right to buy bitcoin. Go at it." Amid supportive political shifts and competitors like Goldman Sachs advancing similar services, the move signals ongoing mainstream integration, empowering the largest operators with bitcoin tools.

VanEck's latest report highlights a 4% decline in Bitcoin's network hashrate, the sharpest since April 2024, driven by worsening miner economics and a shutdown of 1.3 gigawatts of capacity in China's Xinjiang region affecting some 400,000 machines. Analysts Patrick Bush and Matthew Sigel view this miner capitulation as a contrarian signal often preceding stronger price performance, with negative 90-day hashrate growth historically yielding average 180-day Bitcoin returns of 72%. Amid a 9% price dip over the past month, digital asset treasuries accelerated accumulation, adding 42,000 BTC from mid-November to mid-December, their largest monthly haul since July 2025, led by Strategy's 29,400 BTC purchase. “While profitability for miners has been poor recently, many entities continue to mine despite periods of poor economics because they believe in Bitcoin’s future,” the report notes. Long-term holders remain steadfast, underscoring conviction in the industry's trajectory.
