Amsterdam-based Bitcoin development collective 2140 has published its first annual report, offering a detailed account of its inaugural year funding and housing full-time protocol contributors. According to 2140’s Substack, the four-person team spent 2025 working across Silent Payments integration in Bitcoin Core and libsecp256k1, the SwiftSync prototype, Kyoto (a BIP-158 light client), a new mining interface for Core, and ongoing work on libmultiprocess and libbitcoinkernel. The report is candid about operational friction: work visa navigation, cross-border onboarding, and the overhead of standing up a new legal entity consumed more bandwidth than anticipated. 2140 frames the transparency explicitly as a design choice, writing that “the developers, funders, and community members who believe in what we’re doing deserve to see exactly how we’ve used the support we’ve received.” The model mirrors Spiral and Brink in providing salaried stability to open-source contributors, and 2140 states outright that it hopes the report serves as a replication blueprint for similar development hubs elsewhere. More geographically distributed funding infrastructure is the long-run goal.

Founder & CEO of Elektron Energy, Rapha Zagury, has publicly launched Elektronics.dev, a free data platform consolidating hundreds of charts, calculators, and simulators across Bitcoin’s network, price history, mining hardware, and public equities. According to Zagury’s announcement thread, the tool grew from personal scripts built over years of research, with AI tooling enabling consolidation into a clean interface. The ASIC database alone covers 177 models dating back to 2013, each with hashrate, power draw, J/TH efficiency, historical pricing, and a sensitivity heatmap that models ROI across electricity cost and BTC price ranges simultaneously. Network stats run from genesis, including block timing distributions, fee heatmaps by day and hour, empty block analysis, and the security budget curve. A returns section features what Zagury calls a periodic table of annual returns, placing bitcoin beside equities, gold, treasuries, and commodities, color-coded by year. “Bitcoin has been the best-performing asset class in nine of the last fifteen years,” the thread notes, “the worst in two.” The project is self-described as a hobby and beta, but the scope reflects serious long-form research work made accessible.

The Bank of England is walking back core elements of its stablecoin regulatory framework after its own deputy governor acknowledged the original proposals were too restrictive. According to The Block, Deputy Governor Sarah Breeden told reporters the central bank is reconsidering a 20,000-pound individual holding cap per coin and a requirement that 40% of issuer reserves sit in non-interest-bearing BoE deposits. Breeden said “the way limits were proposed is cumbersome operationally for a temporary measure,” and that the Bank is open to alternative approaches to achieving its financial stability objectives. The reversal is explicitly competitive in context: the US GENIUS Act has passed and the EU MiCA regime is already in effect, putting pressure on UK regulators to avoid locking sterling-backed issuers out of a fast-moving market. The stakes are measurable — sterling stablecoins currently account for less than 0.5% of a 315 billion dollar global market, a share that reflects how far the pound has fallen behind the dollar in digital asset infrastructure. Updated draft rules are expected before the end of June, with a final framework to follow later in 2026.

Marty Bent at TFTC connects a set of converging sovereign debt signals that are difficult to dismiss individually and harder to ignore together: the US 30-year yield has cleared 5% for the first time since 2007, Japan’s 20-year bond hit its highest level since 1997, US interest expense crossed $1.27 trillion over the last 12 months, and global M2 sits at $121.9 trillion growing at 7-8% annually. FRED data Bent cites shows US interest expense went from $5.35 billion in Q1 1947 to $586 billion in 2019, then more than doubled to over $1.2 trillion in just six years. “As Lyn Alden likes to say, nothing stops this train. They are going to need to print,” Bent writes. The trap he describes is structural: cutting rates to ease the debt burden risks re-igniting inflation already tracking the 1970s pattern at a 0.93 correlation; holding or hiking accelerates the interest expense spiral. Current CPI sits at 3.78%, right at the inflection point where inflation re-accelerated in the late 1970s before peaking near 14%. Bitcoin, Bent concludes, is the asset purpose-built for exactly this environment.
