1. quantum
Glassnode Research has quantified bitcoin’s quantum-exposed supply at 6.04 million BTC, or 30.2% of all issued bitcoin, in a new report that breaks the risk into two distinct buckets. Structural exposure accounts for 1.92 million BTC, covering outputs whose script type permanently reveals the public key by design, including early P2PK outputs, bare multisig, and modern Taproot addresses. Operational exposure, driven by address reuse, partial spending, and custodian behavior, accounts for the larger share at 4.12 million BTC. “About half of labeled exchange-held BTC is in the susceptible bucket, compared with less than 30% of non-exchange supply,” the report notes. Exchange balances represent roughly 1.66 million BTC of the total exposed supply. Entity variation is extreme: Coinbase shows only 5% exposure, while Binance sits at 85% and Bitfinex at 100%. Notably, the US, UK, and El Salvador government holdings show 0% quantum exposure under Glassnode’s methodology. The framework confirms that the quantum threat to bitcoin is concentrated in custodial behavior rather than the protocol itself, pointing to address hygiene and custody architecture as the primary levers for reducing aggregate network exposure before post-quantum signature standards are deployed.

Bernstein has issued Outperform ratings on four U.S.-listed bitcoin miners, naming IREN as the top pick with a $75 price target, alongside Riot Platforms, CleanSpark, and Core Scientific, framing an estimated $90 billion wave of AI infrastructure investment as the key rerating catalyst. Brian Danga reports in The Block that Bernstein shifted from a traditional discounted cash flow methodology to a sum-of-parts valuation that applies a $3 million per megawatt multiple to power sites earmarked for AI data centers. Core Scientific’s target was raised to $24 from $17, Riot to $25 from $19, and CleanSpark to $24 from $20. The central thesis is that miners who secured permitted sites and energized substations to run ASIC rigs now control the infrastructure hyperscalers need for dense GPU deployments. “Bitcoin miners with active AI contracts trade at roughly $6 million per planned megawatt,” the firm notes, double the valuation assigned to pure-play mining operations. CoreWeave’s multi-billion-dollar hosting deal with Core Scientific, which expects 590 megawatts of IT load by early 2027, serves as sector proof-of-concept. For miners navigating compressed hash revenue after last year’s halving, AI colocation is rapidly becoming the primary valuation driver.

Canaan has won a competitive bid to supply bitcoin mining hardware as the heat source for an 8-megawatt district heating network in the Nordic region, marking the company’s most substantial hash-to-heat deployment to date. Reporting by EnergyMag AI in The Miner Mag notes that the project uses Canaan’s Avalon A1566HA hydro-cooled units, which produce hot water at approximately 80 degrees Celsius for direct integration into existing district pipes, and will serve approximately 2,800 homes. A 2-megawatt first phase comprising 228 units is already operating; the customer placed a follow-on order for an additional 6 megawatts using 692 units in March 2026. “The heating nodes consist of numerous parallel A1566HA units that support dynamic overclocking and underclocking,” Canaan stated in its press release, enabling stability that single-source boiler systems cannot match. The Nordic deployment is Canaan’s second major hash-to-heat announcement this year, following a greenhouse heating pilot in Manitoba. It arrives the same week that Canaan reported a 24% year-over-year revenue decline in Q1, underscoring how hardware manufacturers are pursuing non-mining revenue streams to offset weakness in equipment sales. District heating in Northern Europe, where fossil fuel replacement targets are legally mandated, represents a structurally favorable market for compute-integrated thermal infrastructure.
-EDITOR·OP_DAILY4. human
Sofia Karstens writes in Brownstone Institute that the dominant response to artificial intelligence — techno-optimism on one side and techno-panic on the other — both miss the deeper question, which is not what AI can do but what it does to the conditions under which human agency is possible. The essay draws on the Rousseauian concept of the noble savage not as a romanticized primitive but as a baseline for understanding what is lost when the environment that shaped human cognition is systematically replaced by one optimized for machine legibility. “This is not just a political or technological battle. It is a question of what it means to remain human,” Karstens writes. The piece situates the AI transition within a longer history of technological systems that constrain rather than expand the range of choices available to individuals — from surveillance capitalism to platform dependency. For a freedom-tech audience, the essay provides useful philosophical scaffolding for why technical sovereignty (self-custody, local AI, open protocols) is not merely a security preference but a response to a genuine anthropological pressure. The argument connects naturally to debates about AI assistants, data brokers, and the enclosure of cognitive infrastructure that animates much of the Bitcoin and open-source software communities.
