According to Bitcoin Core developer AJ Towns in a Delvingbitcoin post, the controversial OP_RETURN relay changes shipped in Bitcoin Core 30.0 last October have seen minimal adoption in actual blockchain usage. Towns analyzed roughly 24.4 million transactions with OP_RETURN outputs between September 2025 and February 2026, finding that only 61 transactions included multiple OP_RETURN outputs and just 396 exceeded the previous 83-byte size limit. Towns notes that "large OP_RETURNS accounted for 0.44% of usage by bytes, versus 0.0016% counting by transactions," with half of oversized transactions containing less than 210 bytes and only 10% exceeding 10 kilobytes. The data suggests the relaxed defaults, which allow up to 100 kilobytes across multiple OP_RETURN outputs per transaction, have not triggered the blockchain bloat some critics anticipated. The findings align with separate analyses by Murch and mempool.space researcher Orangesurf, indicating that existing Bitcoin use cases remain well within historical OP_RETURN constraints despite expanded relay policy.

Bitcoin's Lightning Network processed an estimated $1.17 billion across 5.22 million transactions in November 2025, according to River researcher Sam Wouters, marking the payment layer's first month exceeding $1 billion in volume despite subdued bitcoin prices throughout the year. River's third annual Lightning study aggregated data from major node operators including ACINQ, Breez, Kraken, Lightspark, and Wallet of Satoshi, covering 50.6% of total network capacity before extrapolating network-wide estimates. Wouters notes that "Lightning adoption happened despite the price declining all of November and generally not doing much in 2025," with growth driven primarily by exchange integrations and expanding merchant acceptance. The average transaction size reached $223, up from $118 in 2024, reflecting Lightning's dominant use case of moving funds between exchanges rather than micropayments. Transaction counts declined year-over-year as experimental gaming and messaging applications that generated millions of small payments in 2023 failed to achieve deep product-market fit, though Wouters anticipates future spikes as developers experiment with AI agent payments that lack the mental transaction costs constraining human users.

Public bitcoin miners collectively hold roughly 11 gigawatts of operational power capacity but claim another 30 gigawatts in development pipelines as they pivot toward AI data center infrastructure, according to analysis by TheEnergyMag. The three-to-one gap between online and planned capacity reflects what the author calls "the megawatt arms race of the AI boom," where miners face pressure to monetize stranded energy assets amid sustained hashprice compression. The piece notes that "pipeline can mean everything from a signed lease and an active construction site to a project in feasibility studies, a grid application, or simply a target a company is marketing," highlighting fragility in widely cited capacity figures. Riot Platforms exemplifies the sector's identity churn, evolving from biotech to Riot Blockchain to its current form while facing activist investor pressure to accelerate its shift from mining to GPU colocation. The operational challenge extends beyond capital deployment: unlike bitcoin mining's straightforward power-plus-ASICs formula, AI infrastructure monetization depends on product fit, sales execution, and service delivery, creating commercial risk even after power delivery succeeds.

Trey Sellers of the FIRE BTC newsletter has launched the FIRE BTC Compass, a free browser-based calculator that helps users track progress toward financial independence using a bitcoin-weighted portfolio framework. Unlike conventional FIRE calculators that assume a stock-only portfolio and the standard 4% withdrawal rule, the Compass generates a BTC-adjusted target that accounts for bitcoin's asymmetric return profile, producing what Sellers calls "the head start that holding bitcoin gives you." The tool maps users onto a nine-level financial independence spectrum, calculates savings rates and projected timelines under both traditional and bitcoin-adjusted models, and stores all data locally with no accounts, cookies, or server-side storage. Sellers, who has tracked his own portfolio daily since 2019, built the tool around a core premise: "a portfolio with meaningful bitcoin exposure needs less to achieve the same level of security." The full feature set is currently free during a feedback period before moving behind a paywall, with projections, expense tracking, and export features on the roadmap.
