#ETH走势分析 Ethereum Fusaka quietly went live in the early hours yesterday—did you notice?

Unlike the frenzy that swept the entire network during the PoS Merge or the Dencun upgrade, this time there was barely a ripple. The reason is simple: Fusaka isn’t about conceptual revolution; it’s pure engineering optimization—cutting costs, boosting efficiency, fixing bugs. Sounds boring? But this is exactly what a mature public chain should be doing. Let’s break it down and see what real value this upgrade brings.

**L2 Costs Slashed by Half**
Data availability ((DA)) cost has always been a pain point for Layer 2s. Fusaka introduces PeerDAS random sampling verification, combined with an 8x expansion in blob capacity, which cuts L2 transaction fees by half. What does this mean? RWA projects on Arbitrum see a significant drop in operating costs, micro-payments in the Base ecosystem become feasible, and high-frequency DeFi and blockchain gaming apps like MegaETH finally have room to breathe. Lower fees aren’t just a numbers game—they’re the real key to unlocking the application layer.

**Burn Mechanism Back on Track**
Remember after Dencun, when blob fees plunged and the mainnet experienced slight inflation? Fusaka introduces EIP-7918 to set a minimum base fee, essentially applying a “minimum spend” for L2s—even if the network is quiet, the required $ETH still gets burned. The average daily burn rate is returning to pre-Dencun levels, deflation expectations are stabilizing again, and Ethereum’s value as a global settlement layer is once again on solid ground.

**TPS Boost: Low-Key but Solid**
Gas Limit has been raised to 60 million, and mainnet throughput has clearly increased. Don’t dismiss the bump of a few dozen TPS as insignificant—this is Ethereum’s direct response to high-performance blockchains. With rollup scaling plus L1 settlement working together, the flexibility is there, and the future potential goes far beyond the surface numbers.

**Decentralization Finally Realized**
PeerDAS lowers the hardware requirements for validators by 85%—lightweight sharding is no longer just a PowerPoint slide. With lighter node burdens, true decentralization becomes possible. Institutions like Fidelity and BlackRock can more easily participate in staking and operations, allowing the entire Ethereum economic flywheel to truly start spinning.

Is this low-key Fusaka upgrade a silent buildup before takeoff, or a steady adjustment for the long run? What changes will this bring to the L2 ecosystem?
