How Ethereum’s Fusaka Upgrade Strengthens UXLINK’s RWS Infrastructure On December 3, 2025, Ethereum successfully activated the Fusaka upgrade — a major network enhancement focused on lowering data costs, improving account abstraction, and increasing execution performance across Layer‑2 ecosystems. For UXLINK, whose RWS (Real World Social) protocol brings real‑world social relationships on‑chain, Fusaka directly strengthens the foundation needed for scaling social interactions, onboarding millions of new users, and enabling future RWA and stablecoin distribution flows. This article explains what Fusaka is, why it matters, and how it enhances UXLINK’s ecosystem. What Is Ethereum’s Fusaka Upgrade? Fusaka is one of Ethereum’s most impactful upgrades in 2025. It delivers improvements in three major areas: • Lower data availability (DA) costs More efficient blob compression and posting → significantly cheaper costs for L2 data settlement. • Enhanced Account Abstraction (AA) capabilities Optimizations around ERC‑4337, bundlers, and paymasters → reduces friction for new users and simplifies smart account operations. • Higher network throughput and L2 resilience Better handling of peak activity across rollups → more stability for applications with high-frequency interactions. Quick Primer: What Is UXLINK’s RWS Protocol? UXLINK’s RWS (Real World Social) protocol is a social infrastructure layer that: - Maps real-world acquaintance networks onto the blockchain - Uses trust proofs (e.g., “common acquaintance proofs”) - Enables on-chain social verification without exposing personal data - Supports tasks, groups, invitations, and identity-linked interactions - Powers UXLINK’s 50M+ global user base RWS requires low-cost, high-frequency blockchain interactions — exactly the kind of environment Fusaka enhances. 1. Improved Account Abstraction → Frictionless User Onboarding Fusaka strengthens AA and ERC‑4337 flows, enabling: - Gasless onboarding - Fewer pop-up signatures - Simplified smart account operations for newcomers Why this matters for UXLINK RWS interactions — adding connections, joining groups, completing tasks — become smoother and more intuitive. Benefits include: - Lower friction for Web2 → Web3 migration - More scalable community campaigns - Lower Paymaster costs for UXLINK‑sponsored gas This is a major boost for onboarding users across Asia、MENA、LATAM，etc. 2. Lower Data Availability Costs → Cheaper RWS Social Proofs Fusaka reduces L2 DA posting costs by a large margin. For UXLINK, this means: - Cheaper on-chain social proofs for trust verification - Ability to store more RWS data on-chain - Higher transparency and credibility for social verification Example: Posting thousands of RWS trust proofs (e.g., group interactions, connection attestations) becomes more affordable, enabling more robust on-chain social networks. 3. Higher Network Throughput → Stable Large‑Scale Social Activity Fusaka increases Ethereum’s execution stability under high load. Impact on UXLINK Massive community events and quests run more smoothly Lower risk of congestion during peak-hour social interactions Stronger foundation for future value flows such as: - RWA distribution - Stablecoin rewards - Fujipay batch payments - Fujicard on-chain to off-chain spending As UXLINK integrates USDT and other compliant stablecoins, throughput and reliability become even more critical. What This Means for Users and Builders For Users - Faster interactions - No need to hold ETH for basic actions - More seamless RWS experiences For Communities - Scalable campaigns - Lower cost for engagement activities - Higher reliability during major events For Developers / Partners More RWS data can be incorporated into your dApps Easier integration with UXLINK identity & trust layers Better environment for building RWA, payments, or social-based utilities FAQ Q1: Do UXLINK users need to do anything after Fusaka? No — improvements happen at the protocol/network level, and RWS benefits automatically. Q2: Will UXLINK move more data on-chain now? Yes. Lower DA costs mean more RWS social proofs can be safely stored on-chain. Q3: Does Fusaka impact Fujipay and Fujicard? Indirectly — cheaper and more stable transactions strengthen both payment flows and future RWA distribution paths. Conclusion: A Stronger Foundation for UXLINK’s RWS Vision Fusaka isn’t just an Ethereum upgrade. It reinforces the core infrastructure needed for UXLINK’s long-term roadmap: - RWS trust proofs become cheaper - Onboarding becomes smoother - Large-scale, real-world social interactions become more stable As Ethereum becomes more efficient, UXLINK is positioned to scale real-world social networks — and the value flows built on top of them — faster than ever. #UXLINK #Fusaka #Ethereum
