1. quantum
Paradigm General Partner Dan Robinson has published a protocol mechanism called Provable Address Control Timestamps, or PACTs, designed to protect dormant Bitcoin from future quantum attacks without requiring any changes to the Bitcoin protocol. Reporting in The Block, the model works by having a holder sign a message containing a recent block height, broadcast it to the network, and allow miners to timestamp that proof permanently on-chain — offchain and anonymously, requiring no fund movement and no disclosure of address ownership. The proposal targets roughly 6.9 million bitcoin currently exposed to quantum attack because their public keys are visible on-chain, including wallets attributed to Satoshi Nakamoto. Robinson notes users who generate a PACT before cryptographically relevant quantum computers arrive “could use the proof to reclaim access to their funds at any time” following any emergency fork. The approach sidesteps Bitcoin’s most contested governance question — what to do with dormant coins — without violating the self-custody principle.

Galoy has unveiled an expanded Bitcoin-native core banking platform ahead of the Bitcoin 2026 conference in Las Vegas, bundling six use cases into a single system aimed at U.S. banks and credit unions. Micah Zimmerman in Bitcoin Magazine reports the update covers Bitcoin-backed lending, Lightning payments, stablecoin payments aligned with emerging legislative frameworks, Bitcoin exchange under the OCC’s riskless principal model, custody options, and embedded wallet infrastructure. Rather than replacing core banking systems, Galoy’s software acts as a “sidecar,” sitting alongside legacy rails so institutions avoid the multi-year disruption of a full core replacement. The company also released three compliance tools: a Regulatory Radar that aggregates guidance from federal and state agencies into plain language summaries, a Portfolio Analyzer, and LTV Risk Scenarios that let executives model how a Bitcoin lending book would behave under stress. Last year Galoy launched Lana for Bitcoin-backed loans at community banks. The expanded platform signals that the regulatory clearing of Choke Point 2.0 has opened a real commercial window for Bitcoin infrastructure inside the traditional banking stack.

Tether CEO Paolo Ardoino has disclosed that Tether has been among the top ten buyers of U.S. Treasury bills over the past two years, with the company’s Q1 2026 attestation showing $141 billion in U.S. Treasury exposure across $191.7 billion in total assets. The Q1 results posted $1.04 billion in net profit and an $8.2 billion reserve surplus, with the USDT user base reaching a new all-time high of 570 million. Ardoino noted that “67 billion USDT are currently held as savings across many millions of users, especially those in developing countries,” framing stablecoins as functioning infrastructure for dollar-denominated savings in inflation-pressured emerging markets. The disclosure positions Tether alongside sovereign wealth funds and major central banks as a structural buyer of U.S. debt — a reversal of the narrative that stablecoin issuers represent systemic risk rather than systemic support. For the Bitcoin ecosystem, Tether’s scale also anchors the liquidity environment that drives on-chain activity, making its reserve health a material factor in the broader market’s stability.

ARK Invest has published its annual Big Ideas 2026 report projecting Bitcoin’s market capitalization will reach $16 trillion by 2030 — more than a tenfold increase from its current level of roughly $1.5 trillion. Reporting in CoinDesk, the forecast is built across six demand channels: institutional investment against a $200 trillion global portfolio, digital gold demand, nation-state treasury adoption, corporate treasury allocation, on-chain financial services including Lightning and Layer 2 networks, and emerging market safe haven use. The report states “Bitcoin is maturing as the leader of a new institutional asset class,” noting that U.S. ETFs and public companies held about 12% of total supply at year-end, up from 9% the prior year. ARK raised its digital gold addressable market estimate by 37% to $24.4 trillion after gold’s 64.5% surge in 2025, while trimming its emerging market safe haven penetration assumption by 80% — acknowledging that stablecoins are absorbing demand that Bitcoin once seemed positioned to capture. The report is less a guaranteed target than a map of where institutional demand has to come from, and where the constraints actually lie.
