Bitcoin vs. AI Computing: Who Leaves the Bigger Carbon Footprint?
BTC mining became crypto’s environmental problem long before AI; now AI data centers spark the same debate. AI data center power demand is driving rapid growth, with 33-80 Mt CO₂e in 2025 and far higher scaling ahead. Experts warn that AI may soon surpass Bitcoin’s footprint by 2030 as inference demand rapidly grows. Bitcoin (BTC) mining and artificial intelligence (AI) computing both consume massive amounts of electricity, sparking an intense debate over their environmental impact in 2026. Bitcoin, the pioneering cryptocurrency, secures its decentralized network through energy-intensive proof-of-work mining that consumes 150-170 TWh yearly and emits 65-75 million tonnes (Mt) of CO₂e. Meanwhile, AI computing powers everything from large language models like GPT, image generators, and recommendation systems in massive GPU data centers, already producing 33-… Read The Full Article Bitcoin vs. AI Computing: Who Leaves the Bigger Carbon Footprint?

Grayscale Backs Ethereum Staking Reward Cap as ETH Supply Concerns Mount
Ethereum is working through a serious structural debate about its staking reward model, with asset manager Grayscale publishing research that explicitly backs proposals to cap how much validators can earn above certain staking thresholds, arguing the change would be “positive for the price of ETH” over time. The report, authored by Grayscale’s Head of Research Zach Pandl, identifies two compounding problems that have quietly shifted Ethereum from a deflationary to an inflationary token since its peak burning period. The first issue is the collapse in Layer 1 transaction fee revenues. As more activity has migrated to cheaper Layer 2 networks, the base fee burned on every Ethereum transaction has declined substantially. Annual gross inflation now sits at approximately 1 million ETH, with the token burn rate failing to keep pace. The second structural problem is that the marginal cost of staking ETH has fallen to near zero. When Ethereum first introduced proof-of-stake, staked assets were locked with no withdrawal option, imposing a genuine liquidity premium on validators. With withdrawals now enabled and liquid staking tokens, ETFs, and corporate treasury vehicles all competing to stake at minimal cost, that risk premium has essentially disappeared. The consequence, Pandl warns, is that if current incentives persist, virtually all ETH could eventually end up staked, creating unnecessary dilution and dangerous centralisation risk if a handful of large validators control the majority of staked supply. The Ethereum community is currently discussing proposals including EIP-7917, which would introduce tiered or capped reward curves. Under these models, validators staking beyond a defined threshold would receive diminishing or zero additional rewards, structurally reducing the incentive to over-stake. Grayscale’s research points out that capping issuance above certain staking ratios would slow supply growth and enhance ETH’s scarcity characteristics. The firm draws an analogy to commodity markets, where constrained production typically supports long-term prices. A record 32% of all ETH is currently staked, with the base staking yield sitting at approximately 3.0-3.2%, down roughly 40% from levels above 5% in late 2022. As of Friday morning, ETH is trading at approximately $2,255, up around 1.4% over the past 24 hours and maintaining a market capitalisation of roughly $272 billion. Whale wallets have been accumulating heavily in recent sessions, with on-chain data indicating purchases of over 140,000 ETH in a 96-hour window earlier this month. The upcoming Glamsterdam upgrade, targeting June 2026, is expected to significantly increase Layer 1 throughput and is viewed by some analysts as a catalyst that has not yet been fully priced into the market. Whether the staking reward debate ultimately results in a protocol change will depend on community consensus, a process that on Ethereum tends to move slowly, though Grayscale’s public backing adds weight to the reformist camp.

Ethereum News: Vitalik Buterin ‘Puts Skin in the Game’ with $113K Privacy Pools Transfer
In the latest news, Ethereum co-founder Vitalik Buterin transferred 50.25 ETH, approximately $113,000 at current prices, through Privacy Pools , the compliance-aware privacy protocol he co-authored in a 2023 research paper, publicly validating the tool with real capital rather than white-paper advocacy. The move comes weeks after 0xbow.io launched the protocol on Ethereum mainnet on March 31, 2025, positioning it as a regulatory bridge between user privacy and AML obligations. Buterin putting skin in the game is a signal, not a transaction. Bullish signal for compliant privacy infrastructure on Ethereum. Source: Arkham The amount is deliberately modest relative to Buterin’s holdings; this is a functional demonstration and a public statement, not a liquidity event. The central question the transaction raises is whether Privacy Pools can thread the needle that Tornado Cash could not: preserving meaningful Ethereum privacy while satisfying the on-chain security and regulatory standards that led to its predecessor’s sanction. Discover: The best pre-launch token sales How Privacy Pools Work Mechanically, and Why the Zero-Knowledge Architecture Changes the Compliance Calculus The mechanism here is worth understanding precisely. Privacy Pools uses zero-knowledge proofs to allow a user to demonstrate that their withdrawal belongs to an approved “association set”, a curated subset of deposits filtered by off-chain analysis and encoded on-chain, without revealing which specific deposit was theirs. The user proves the fund’s cleanliness without surrendering their identity. Those are not the same thing as full disclosure, and the distinction matters enormously for the regulatory argument. Tornado Cash, sanctioned by OFAC in August 2022, offered no such selectivity. Every deposit was mixed indiscriminately, which meant honest users shared anonymity sets with wallets tied to North Korea’s Lazarus Group and other sanctioned actors, and regulators had no mechanism to distinguish between them. Privacy Pools encodes the distinction on-chain from the start. @0xprivacypools v2 public testnet is now live! you can now make private transfers within the pool that don't reveal any details! @0xmikemcc , product lead at @0xbowio has been interviewed by @mdoorfard at @EthCC in Cannes. Watch the interview on YouTube: https://t.co/vuk2hUdfcA pic.twitter.com/CorrQlkro1 — coinix (@coin_ix) May 14, 2026 The 0xbow implementation adds a semi-permissive operational layer: initial deposits are capped at 1 ETH per address, and the team retains the ability to pause new association sets if clear sanctions or AML issues emerge, while keeping withdrawals permissionless. As of launch week, the protocol recorded more than 21 ETH across 69 individual deposits, including Buterin’s. The anonymity set is small but growing. The white paper argues that regulators could require users to produce proofs derived from “good” association sets rather than demanding full transaction histories, making compliance audits more targeted and less invasive than current surveillance-first approaches to Ethereum privacy. Ethereum news: Why Buterin’s Privacy Pools Move Matters Beyond the $113K Transaction The post-Tornado Cash landscape left Ethereum’s privacy infrastructure in an awkward position: the most widely used privacy tool was sanctioned, and no credible replacement existed. Privacy Pools is the most architecturally serious attempt to fill that gap, and Buterin’s public use of it shifts it from a research proposal to a live, endorsed protocol in a single transaction. The broader ecosystem context matters here. The CLARITY Act faces more than 100 amendments as legislators continue debating the regulatory perimeter around digital assets, including privacy tools. How Congress and OFAC ultimately treat selective-disclosure protocols will determine whether Privacy Pools becomes infrastructure or a footnote. 0xbow has backing from Number Group, BanklessVC, and Public Works, Coinbase Venture signaling VC conviction that regulation-friendly privacy is a distinct infrastructure category worth building toward. 0xbow Funding Rounds / Source: Cryptorank The roadmap includes extending support for ERC-20 assets and integrating wallet and compliance dashboard tooling, which would dramatically expand the protocol’s reach beyond ETH-native users. Meanwhile, Ethereum ecosystem activity continues to carry meaningful financial stakes for institutions watching on-chain developments closely. If regulators treat Privacy Pools-style proofs as a valid compliance mechanism, the protocol becomes a template for the next generation of privacy tooling across DeFi. If OFAC applies the same blanket logic it used against Tornado Cash, it forecloses the compliant privacy thesis entirely and pushes privacy tooling back underground. The cryptography is settled. The regulatory verdict is not. Buterin’s 50.25 ETH transfer is the most credible public endorsement Privacy Pools has received. The association-set governance question is the variable that determines whether it survives regulatory scrutiny. That question runs directly through OFAC, and through whatever framework emerges from the current congressional markup.
