Some friends are puzzled as to why the Ethereum Fusaka upgrade hasn't generated much buzz. In fact, this upgrade is different from previous ones; it doesn't play with concepts or engage in innovation, but rather focuses on genuinely reducing costs, improving efficiency, and enhancing the experience to solve real problems. I believe this is what a mature public chain should look like; let’s take a look at what benefits it really brings.

First, the cost of L2 has significantly decreased. Currently, the main expense of L2 is the DA cost for sending data to L1. Fusaka has expanded Blob storage by 8 times, and then used PeerDAS for random sampling verification, cutting the cost by more than half. Some people think that lowering L2 fees is useless, and that ecological activity is the key. But from another perspective, looking at dedicated application chains, for example, with the reduced fees on Arbitrum, RWA infrastructure becomes more active; if Base fees are further reduced, the x402 payment ecosystem can directly benefit; the upcoming Megaeth will also expand high-frequency DeFi and gaming scenarios. So don’t just look at how much the fees have decreased, but also at which high-frequency scenarios have been activated due to the cost reduction.

Second, the Blob fee market is normal, and the expectation of ETH burning is back. After the Dencun upgrade, Blob fees have decreased, and the mainnet no longer has L2 support, turning Ethereum from deflationary to micro-inflationary. Fusaka introduces a minimum Blob base fee; even if Blob demand is low, L2 still has to pay a minimum toll. ETH will still burn as it should. If the average daily burning of ETH returns to previous levels after the upgrade, deflation is not far away, and the story of ETH as a global settlement layer value anchor can continue.

Third, Gas Limit raised to 60M, significantly enhancing L1 throughput. Some public chains now have TPS exceeding 100,000, and people don't feel the impact of Ethereum improving by dozens or hundreds of TPS. But this time Ethereum is really going to boost TPS, with high efficiency, clearly aiming to compete directly with Solana. Coupled with its long-term strategy to improve L1 performance, it truly deserves praise. Previously, Ethereum relied solely on Rollup, which was greatly limited by L2; now, with L1 settlement + L2 execution running in parallel, there is much more room for imagination.

Fourth, PeerDAS reduces the validator threshold by 85%. This is a change in the Fusaka upgrade that is easily overlooked but highly significant. With a random sampling verification mechanism for a small portion of data, the decentralization of Ethereum Validators can be significantly improved, addressing Vitalik's concerns about institutional control over Ethereum. To some extent, PeerDAS is a lightweight implementation of Ethereum's sharding concept, which can reduce the burden on nodes, enhance network scalability, and improve decentralization. Moreover, it removes the technical barriers for institutions to enter, allowing traditional financial giants like Fidelity and BlackRock to deeply participate in the Ethereum ecosystem, marking the starting point for Ethereum's explosion.

In summary, a more mature, robust, and efficient ETH that can also accommodate institutional expansion, L1 + L2 dual-track development, and micro-deflationary value capture is worth trusting again, don't you think?

Brothers, a strong coin that can explode and earn 10 times is here. I will prepare for a big wave in the upcoming market, and this time, a successful gamble can definitely earn a lot.Chat room.#美联储重启降息步伐 #加密市场观察
