Latest from IBM Quantum and Google Research
QSHA256 live data: 170,669,431 UTXOs must move to post-quantum cryptography before a cryptographically relevant quantum computer exists. The minimum floor is 69.6 days of fully dedicated block space — and the JIT attack means partial migration offers no protection at all.
Google Quantum AI proves ECDLP-256 can be broken with fewer than 500,000 physical qubits — a 20× reduction from prior estimates, executable in minutes. QSHA256 analysis covering resource estimates, the ZKP disclosure framework, PQC migration, and implications for the 6,946,360 BTC currently tracked at quantum risk.
Comparative analysis of the Pinnacle Architecture (arXiv:2602.11457) and Google’s ECDLP-256 disclosure — two independent teams, six weeks apart, using different error correction paradigms to attack different cryptographic problems, arriving at the same verdict. Includes all three Google whitepaper figures: logical resource frontier, Race Against the Block, and the quantum salvage operation harvest curve.
Analysis of the Pinnacle Architecture paper (arXiv:2602.11457): QLDPC codes reduce RSA-2048 factoring to 100,000 physical qubits, an order of magnitude below previous estimates. Implications for Bitcoin, ECDSA, and Q-Day timelines.
Developer-level analysis of BIP-360 and BIP-361: Bitcoin's architectural path to post-quantum security through staged, backward-compatible soft-fork migration. Includes script templates, validation semantics, and UTXO exposure risk mapping.
Deep analysis of why ECDSA signatures face existential threat from Shor's algorithm while SHA-256 hashing remains resilient. Includes qubit requirements table and the 6.92 million BTC already at risk.
Why the crypto community needs real-time quantum vulnerability monitoring now, before Q-Day arrives. How QSHA256 maps Bitcoin's exposure and why it matters.
Total blockchain quantum exposure across all 7 address types. Data sourced at block #947,271.
