GOP senators introduced legislation establishing a federal certification program for domestic crypto mining operations while phasing out reliance on foreign hardware. The US accounts for 38% of global Bitcoin hash rate, but 97% of mining hardware comes from China. The bill codifies Trump's executive order to create a Strategic Bitcoin Reserve on a statutory footing and directs NIST and the Manufacturing Extension Partnership to support domestic hardware development. Certified domestic miners could sell newly mined bitcoin directly to the government in exchange for a capital gains tax exemption, creating an incentive to supply the reserve at discounted prices.

The NFL sent letters to Kalshi and Polymarket asking them to stop offering trades on easily manipulated events, including announcer commentary, celebrity attendance, and draft outcomes, while the CFTC announced it will defer to major sports leagues on identifying which contract types are most vulnerable to manipulation. The NFL defined "objectionable bets" as contracts that could be manipulated by a single person, relate to officiating, or are knowable in advance. MLB took a different approach, striking a partnership with Polymarket earlier this month and signing an information-sharing agreement with the CFTC to internally monitor risks.

BNP Paribas is making six crypto-linked ETNs indexed to Bitcoin and Ether available to French retail clients through standard securities accounts starting March 30, covering individual investors, entrepreneurs, private banking clients, and Hello bank! users, with potential expansion to wealth management clients outside France. There is accelerating European retail access to regulated crypto products: the UK reopened retail crypto ETN access in October 2025 after a four-year ban, and Germany's ING recently added Bitwise and VanEck ETN offerings. BNP Paribas has broader blockchain exposure as well, having joined the Canton Foundation in September 2025, participated in Digital Asset's $135 million funding round, and launched tokenized money market fund shares on Ethereum.

The Ethereum Economic Zone (EEZ) is an L1-L2 framework where rollups extend the Ethereum mainnet with synchronous composability, enabling smart contracts on EEZ rollups to call mainnet contracts atomically within a single transaction. Protocols can deploy once rather than managing separate deployments across chains with isolated bridges, and users transact across the zone without explicit bridging, with ETH retained as both gas token and settlement layer. Jordi Baylina, creator of Circom, zkEVM pioneer, and founder of the Zisk proving stack, serves as technical lead, with the Ethereum Foundation funding the work and the Switzerland-based EEZ Association structuring it as open-source public infrastructure. Founding members include Aave, Centrifuge, Titan, Beaver Build, and xStocks, with the architecture relying on recent advances in real-time proving technology.

Google's Willow quantum supercomputer has pushed the crypto industry from abstract concern to active defense, with Google itself setting a 2029 deadline to migrate its own authentication services to post-quantum cryptography. Bitcoin faces the most contentious path: BIP360 proposes gradual migration to quantum-resistant addresses, while the Hourglass concept would restrict spending of vulnerable coins, leaving roughly 1M BTC, including Satoshi's holdings, exposed if consensus on action stalls. Ethereum elevated post-quantum security to a strategic priority in 2025, with a dedicated research team integrating post-quantum signature schemes into planned LeanVM architectural changes, while Solana shipped a quieter opt-in solution via its December 2025 Winternitz Vault using hash-based one-time signatures.

DTCC, which processed $3.7 quadrillion in 2024, received an SEC No-Action Letter in December 2025 to tokenize US Treasuries with production targeting H1 2026, while NYSE announced a 24/7 on-chain equities and ETF settlement platform backed by BNY and Citi, and Nasdaq filed its own proposed rule change with the SEC. Tradeweb's August 2025 real-time onchain Treasury financing against USDC, executed with Bank of America, Citadel Securities, and Virtu Financial on a Saturday, showed 24/7 settlement at institutional scale is viable on current infrastructure. The thesis is that DTCC, NYSE, and Tradeweb are acting as customers of this infrastructure shift rather than builders, leaving middleware, compliance tooling, and distribution layers as open territory for new entrants, an opportunity the CLARITY Act could accelerate the same way the GENIUS Act accelerated stablecoins.

The Ethereum Foundation's (EF) Platform team published a four-principle framework, repositioning L2s as differentiated feature platforms rather than scaling solutions, consistent with Vitalik Buterin's recent statement that the original L2 vision "no longer makes sense." The framework designates L1 as a permissionless global hub for settlement, liquidity, and DeFi, while L2s are expected to pursue differentiation across privacy, compliance, and sector-specific functionality, with scaling treated as a secondary benefit rather than a primary goal. L2s are expected to achieve Stage 1 trust-minimization with "walkaway" capability and work toward synchronous composability, while retaining access to Ethereum security, developer and user network effects, and secure interoperability with L1 assets. EF commitments include scaling L1 and blob capacity, investing in native rollups, improving L1 liquidity access for L2s, and addressing cross-chain fragmentation.

The 2022 credit contagion exposed undercollateralized DeFi lending's structural gaps, including no shared obligations ledger, no real-time reserve disclosure, and no automatic enforcement – problems that overcollateralized protocols like Aave cannot address because they structurally exclude borrowers who cannot lock up 150%+ collateral. Wildcat Finance's response skips cryptographic trust-solving and instead assumes off-chain trust already exists between sophisticated counterparties, providing onchain infrastructure with borrower-set terms, automatic penalty activation on reserve breaches, and an open-source Master Loan Agreement binding smart contract activity to legal obligations. Onchain credit rails add four durable properties beyond record-keeping: permissionless reserve auditability, automatic consequence mechanics that remove social friction from enforcement, portable credit history compounding across markets on a public ledger, and reduced legal surface area as on-chain mechanics replace operational enforcement.

P2P Protocol's founder placed a Polymarket bet on his own project's MetaDAO ICO hitting $6M in commits, prompting MetaDAO to request removal of those markets, which Polymarket declined.

Stablecoins processed over $33 trillion in 2025, surpassing the combined $24.8 trillion handled by Visa and Mastercard.

Capital is rotating into stablecoins amid volatile markets.

AP Collective published a comprehensive ecosystem map of the real-world asset sector, arguing that RWA is broader than most people think.
