Ethereum Fusaka upgrade is set to go live on the mainnet on December 3, 2025. What are the highlights of this update? First, it introduces the PeerDAS data availability sampling mechanism, allowing nodes to subscribe to only about 1/8 of the rollup's blob data. What does this mean? It signifies a significant reduction in verification costs and a lower participation threshold.

Regarding blob capacity, BPO is gradually increasing, with the ultimate goal of optimizing from the current 14/21. The potential for expansion is limited only by imagination. Another major focus is the security upgrade of zkEVM—according to the roadmap, by the end of 2026, it aims to achieve 128-bit security level, followed by a shift to proof verification architecture, marking a critical transition from computational optimization to security assurance.

A question worth pondering: what impact will this series of Ethereum upgrades have on the Bitcoin settlement layer? Layer 2 scaling solutions are becoming increasingly mature, and cross-chain bridging demands may reshape the landscape. The throughput and security of Layer 2 are both improving, which has profound implications for the competition within the multi-chain ecosystem.

PeerDAS's recent operation directly lowers the participation threshold. Can it really enable more people to run nodes? It still depends on the implementation results. Blob has been optimized from 14 to 21, and the scalability space is indeed impressive, but can the gas fees really come down? zkEVM is aiming for 128-bit security level. That's the real deal. Security takes precedence over scalability. With a bunch of Layer2 solutions for Ethereum, will BTC panic? It feels like multi-chain competition is just beginning. Reducing verification costs by 1/8 sounds great, but what ordinary users care about most is how much they can save on transaction fees. Wait, will cross-chain bridges be reshaped? What impact does this have on existing liquidity pools? Reaching 128-bit security will only happen by 2026. We have to wait, it's too long.

December 3rd is coming, and PeerDAS can indeed lower the threshold, but don't celebrate too early...

This PeerDAS directly lowers the participation threshold, making verification much easier. Finally, the moment we've been waiting for.

PeerDAS this time is really impressive, the node costs are directly cut by 1/8. It feels like running nodes on a home computer is finally promising again... But on the other hand, BPO's actions are a bit slow, we might have to wait until the end of next year to see the real results.

PeerDAS's move is really aggressive, directly cutting verification costs by seven-eighths. Does it feel like the spring for small retail investors to run nodes is coming? Blob capacity is being increased from 14/21, and this expansion potential is a bit hard to imagine... zkEVM is aiming for 128-bit security level, Ethereum is truly heading towards its final form. It seems like the BTC settlement layer is getting a bit panicked? Layer 2 is so powerful, is there still a way for cross-chain to survive? I just want to know, after this upgrade, how will small-cap cross-chain bridges survive?
