Lawson Convenience Store Tests Stablecoin Payments Again: Three Coins, Three Chains, But Japanese Regulators Haven't Given the Nod

Lawson convenience stores have conducted a second-phase pilot test of stablecoin payments in partnership with payment solution provider NetStars, moving stablecoins from exchanges to physical checkout counters. The experiment, conducted at a Tokyo store, tested payments using three stablecoins—USDC, USDT, and JPYC—across three blockchains: Solana, Morph, and Polygon. A key development was the inclusion of USDT, which is not currently on Japan's approved list of electronic payment assets. The test linked Lawson's existing POS system with NetStars' "Stablecoin Pay" service to verify that stablecoin payments could be processed without disrupting store operations. It assessed payment speed, user experience, and handling of various transaction scenarios. Payments were typically completed within five seconds. Users paid with stablecoins via MetaMask, while stores received yen settlements. NetStars covered the blockchain gas fees upfront, charging users a separate "processing fee" that also included potential foreign exchange costs for dollar-denominated stablecoins. Company executives stated the pilot was preparatory, aimed at understanding technical feasibility and challenges ahead of potential wider adoption. They highlighted the appeal of globally-traded stablecoins like USDC and USDT for foreign visitors to Japan, alongside the domestic use case for yen-pegged JPYC. However, the legal and operational framework for converting received USDT into yen remains under discussion with Japanese financial authorities. No timeline for a commercial rollout was given, pending further market demand, user needs, and final economic conditions like fee structures.

The Great Ethereum "Rate Cut" Debate: Is Now the Golden Window for Staking with the Unconventional EIP-8363?

Ethereon's economic policy is under review as a new proposal, EIP-8363, sparks debate over potential "interest rate cuts" for staking. The unconventional proposal suggests gradually increasing the proportion of newly issued ETH rewards that are burned as the total staked ETH ratio rises, with issuance fully offset by burns once the ratio nears 50%. This would drive the protocol-level staking APR towards 0%, though validators would still earn transaction fees and MEV. This discussion emerges as staked ETH approaches 35% of supply, with the current protocol APR at ~2.6%. The core question is whether Ethereum needs to continue paying high issuance costs for marginal gains in security once sufficient participation is achieved. EIP-8363 aims to optimize security spending, but critics warn it could disproportionately impact solo stakers and potentially increase centralization among large, resilient operators. Paradoxically, this debate coincides with the Pectra upgrade (EIP-7251), which introduces native compounding for staking rewards, significantly improving capital efficiency for long-term holders. This creates a dual narrative: the protocol is making staking more efficient while reconsidering the economic incentive to stake. For long-term ETH holders, this environment may present a "time window" rather than a fixed-rate opportunity. While future APRs are expected to trend downward, starting staking earlier maximizes the compounding effect over time. The decision to stake depends on individual factors like investment horizon, liquidity needs, and risk tolerance regarding options like native validation, staking services, or liquid staking tokens (LSTs). The evolution from encouraging staking to managing its economic cost marks a new, mature phase for Ethereum's tokenomics, where the true value of staking may increasingly lie in the long-term power of compounding time.

If Ethereum Had Never Switched from PoW to PoS: An Unrealized Game

"The Great Merge: What If Ethereum Had Stayed on PoW?" This article explores a counterfactual scenario: What if Ethereum had not transitioned from Proof-of-Work (PoW) to Proof-of-Stake (PoS) in 2022? It examines the potential trade-offs of this historical decision. The key argument for a continued PoW path is the missed opportunity in the AI era. Ethereum's GPU miners, unlike Bitcoin's specialized ASICs, could have formed a massive, globally distributed computing network. This infrastructure might have evolved into a decentralized AI cloud, giving Ethereum a strategic position in the AI compute market. Critics argue the switch to PoS prematurely ended this possibility. However, sticking with PoW would have carried significant costs. PoS drastically reduced ETH's daily issuance and miner sell pressure, aiding its "digital gold" narrative and attracting institutional capital. PoW's higher, continuous inflation could have hindered price stability. Furthermore, PoS provides greater design flexibility for scaling solutions (like Rollups and data blobs) and aligns better with environmental (ESG) and regulatory concerns for mainstream finance adoption. In conclusion, the shift from PoW to PoS represented a fundamental strategic choice between two distinct paths: one potentially leading to a smart-contract-enabled "digital commodity" network with vast compute resources, and the other aiming to become a global, efficient settlement layer for the digital economy. The rise of AI has only made the road not taken more intriguing to contemplate.

Wall Street Giant BNY Actively Expands into Crypto Staking Market via Galaxy

Wall Street giant BNY is actively entering the crypto staking market through a partnership with Galaxy Digital. Announced in August 2026, the collaboration will integrate staking services directly into BNY's institutional-grade digital asset custody platform. This allows eligible institutional clients to earn staking rewards while keeping assets within the same custody, fund accounting, tax, and client reporting systems used for traditional assets. Galaxy Digital will provide the underlying staking infrastructure, operating validators on networks like Ethereum and Solana. This move aims to eliminate a major operational hurdle for institutions like pension funds and asset managers, who were previously forced to move assets to separate providers to stake, complicating operations and compliance. BNY, which already custodies Bitcoin, Ether, and supports major ETFs, sees this as expanding its digital asset capabilities for clients. Galaxy framed the deal as part of a shift toward open, programmable financial markets. A key next step is regulatory approval. The service will also need to address inherent risks like validator penalties and the evolving tax treatment of staking rewards.

Lawson Launches Japan’s First POS-Integrated JPYC Stablecoin Payment Trial

Japanese convenience store chain Lawson will launch Japan's first trial of a stablecoin payment system directly integrated with retail point-of-sale (POS) machines in early August. The pilot will take place at a single store in Tokyo, using the JPYC stablecoin, which is pegged to the Japanese yen. Payments will be processed through the HashPort digital wallet platform. Customers will pay by displaying a barcode from a compatible wallet, which store staff will scan as usual; HashPort will then update the JPYC balance based on the transaction. The trial aims to assess whether the system can improve checkout efficiency. Transaction data will be recorded alongside regular sales. JPYC, launched in 2025 and backed by yen deposits and Japanese government bonds, has previously been accepted by some restaurants and clinics, initially with no transaction fees. This initiative is part of broader developments in Japan's regulated stablecoin ecosystem. Major banks plan to introduce yen-based stablecoin services in 2026, following official blockchain trials. The market has also expanded to include approved foreign issuers, such as the Ripple-SBI USD stablecoin launched in 2026. Lawson's test demonstrates the growing application of stablecoins beyond finance into everyday retail payments.

Ethereum uses less power than British Museum – Here’s what changed

Ethereum's transition from Proof-of-Work (PoW) to Proof-of-Stake (PoS) in "The Merge" has drastically reduced its energy consumption. The network now uses approximately 7.87 GWh of electricity annually, less than half the British Museum's usage, marking a reduction of over 99.9% from pre-Merge levels. This has also cut its carbon footprint by 99.98% to an estimated 2.37 kilotonnes of CO2 equivalent per year, comparable to the emissions of about 900 UK households. The Cambridge Centre for Alternative Finance (CCAF) reports that Ethereum's infrastructure remains decentralized, though geographically concentrated, with 62% of nodes hosted in the US, Germany, Finland, and France. About 56.4% of its electricity comes from sustainable sources, primarily nuclear and renewables, exceeding the global average. Future developments like stateless verification may further reduce energy needs. Meanwhile, Ethereum's development enters a new phase with "Lean Ethereum," a multi-year overhaul plan for the network's evolution. At the time of reporting, ETH's price saw a slight increase, trading near $1,800.

Is Ethereum Truly a "World Computer"?

Title: Is Ethereum Really a "World Computer"? Ethereum, envisioned as a "world computer" by its founder Vitalik Buterin, aims to be a decentralized platform for global applications. However, a recent analysis by Four Pillars raises questions about whether it is more accurately a "Western computer," based on the geographical distribution of its validators. Currently, the United States dominates with 38.19% of all validators, followed by Germany at 13.04%. Combined, these two countries account for over half of the network. In contrast, Asian representation is minimal, with Singapore holding only 3.15%. The concentration is partly due to affordable cloud hosting services like Hetzner and OVH in Europe and North America, as well as the prevalence of residential validators in the U.S., where individuals run nodes via home internet connections. When examining professionally operated validators, the distribution becomes more balanced. The U.S. share drops to 25.81%, while Asian countries like Singapore (7.28%), Hong Kong (6.44%), Japan (6.38%), and South Korea (4.59%) collectively approach the U.S. level. This shift reflects strategic deployments by institutions to meet regulatory requirements and reduce latency for local users. However, regions like South America, the Middle East, and Africa remain underrepresented. Ethereum's peer-to-peer network mechanisms, such as gossipsub, disadvantage areas with low node density, creating a feedback loop where delayed message propagation reduces validator performance and rewards. This imbalance challenges Ethereum's promises of censorship resistance and global accessibility. Despite these issues, opportunities exist for growth in underrepresented regions. As demand for localized staking infrastructure rises, early entrants in areas like the Middle East could establish dominant positions by offering compliant, low-latency solutions. The evolving validator landscape highlights both the structural challenges and the potential for Ethereum to move closer to its "world computer" ideal.

Six Complaints from an Ethereum Developer

A disgruntled early Ethereum developer and token holder presents six core criticisms of the project's trajectory, contrasting it with Solana's rise. 1. **Premature Complacency**: The Ethereum Foundation shifted from a "building" to an "infrastructure" mindset too soon, adopting a passive, "retired chairman" posture before securing market dominance, reflected in ETH's ~65% decline against BTC post-Merge. 2. **Misguided Messaging**: The Merge was marketed primarily on ESG (99.95% energy reduction) rather than user benefits like speed or yield, appealing to internal ideals instead of market demands. 3. **Delayed Execution**: Proof-of-Stake, on the roadmap since 2015, took seven years to launch, ceding critical narrative and development windows. Competitors like Solana built entire ecosystems in that time. 4. **Poor Native Staking UX**: Years after the Merge, there is still no first-party, user-friendly staking application, forcing reliance on centralized services like Lido and undermining ETH's "sound money" narrative. 5. **Managed Decline**: The rollup-centric roadmap deliberately weakens the base layer's fee capture, outsourcing value and profitability to L2s like Arbitrum and Base, which issue their own tokens and fragment capital. 6. **Ideology Over Product**: Ethereum culture prioritizes philosophical purity ("credible neutrality," "public goods") over competitive product delivery that meets user demands (e.g., financialization), while Solana's ecosystem focuses on coordinated execution. The diagnosis is accumulated execution debt, not a coordination failure. Ethereum possessed a structural advantage in 2021 but spent years in governance debates, while Solana efficiently executed. The current market cap reflects these specific strategic failures, not abstract theory.

Six Complaints from an Ethereum Developer

Six Grievances from an Ethereum Developer The author, an early investor and developer still building on Ethereum, expresses deep frustration with its trajectory and declining ETH/BTC price since the merge. The core argument is that Ethereum's current market position stems from concrete failures in execution and strategy, not abstract coordination problems. The first grievance targets a shift in the Ethereum Foundation's mentality from builders to "infrastructure," adopting a premature posture of a retired victor. Second, marketing the Merge around ESG (99.95% energy reduction) is seen as talking to its own conscience rather than the market, which prioritizes user experience and yield. Third, the seven-year delay in delivering Proof-of-Stake (PoS) ceded critical narrative and development time to competitors like Solana. Fourth, three years post-merge, there is still no user-friendly first-party staking application, forcing reliance on centralized services like Lido and undermining ETH's monetary narrative. Fifth, the rollup-centric roadmap has strategically surrendered base-layer fee capture to L2s, fragmenting value within the ecosystem while Solana demonstrates an integrated L1's value accrual. Finally, the author criticizes an institutional culture that prioritizes philosophical ideals (credible neutrality, pluralism) over competitive product delivery focused on what users actually want. The diagnosis is "accumulated execution debt." Ethereum possessed a structural advantage in 2021 but spent years in governance debates, while Solana's ecosystem coordinated efficiently to deliver and capture the next wave of value. The conclusion is that Ethereum's market cap reflects its abandonment of the fight for asset appreciation.

Reframing Ethereum's Valuation: Why the Fee Model is Wrong, and the 'Treasury Logic' is the Future?

"Rethinking Ethereum's Value: The 'Vault Logic' Framework" Traditional valuation models incorrectly treat Ethereum as a company, valuing ETH based on transaction fees ("revenue"). This is flawed. Fees are network friction; a successful network aims to reduce them to zero. Ethereum's average fee has dropped from over $50 in 2021 to around $0.20 today, while transaction volume has tripled. Instead, view Ethereum as a digital vault securing ~$250 billion in on-chain assets (stablecoins, RWAs, L2 bridged funds, wBTC, etc.). Post-merge, Ethereum's security is directly purchased with its own asset: ETH. To attack the network, an attacker must acquire and control staked ETH. Therefore, the vault's security level is intrinsically tied to ETH's market value. Currently, the value of all staked ETH is only ~$72B, protecting ~$250B in assets—a dangerous imbalance. For robust security, the staked ETH securing the network should be valued significantly *higher* than the total value it protects. Applying a conservative security multiplier suggests ETH's fair value should be closer to ~$6,900 (vs. ~$2,070 currently). As on-chain asset value grows into the trillions, ETH's price must rise proportionally to maintain this security budget. Comparisons to free infrastructure like Linux or low-margin utilities like the DTCC are misguided. Their security is provided externally (community, law, banks). Ethereum's security is internal and must be purchased in the open market using ETH. ETH is not the clearinghouse; it is the collateral backing it. The model is not a short-term price predictor but a structural framework. The economic force for ETH appreciation grows monotonically with the adoption of Ethereum for settling value. The narrative that high fees are good is backwards; low fees enable more activity, which increases the value needing protection, thus demanding a more valuable ETH.
