Everything changes. Everything is connected. Pay attention.


PeerDAS in Fusaka is significant because it literally is sharding. Ethereum is coming to consensus on blocks without requiring any single node to see more than a tiny fraction of the data. And this is robust to 51% attacks - it's client-side probabilistic verification, not validator voting. Sharding has been a dream for Ethereum since 2015 , and data availability sampling since 2017 ( github.com/ethereum/resea… ), and now we have it. That said, there are three ways that the sharding in Fusaka is incomplete: * We can process O(c^2) transactions (where c is the per-node compute) on L2s, but not on the ethereum L1. If we want to scaling to benefit the ethereum L1 as well, beyond what we can get by constant-factor upgrades like BAL and ePBS, we need mature ZK-EVMs. * The proposer/builder bottleneck. Today, the builder needs to have the whole data and build the whole block. It would be amazing to have distributed block building. * We don't have a sharded mempool. We still need that. But even still, this is a fundamental step forward in blockchain design. The next two years will give us time to refine the PeerDAS mechanism, carefully increase its scale while we continue to ensure its stability, use it to scale L2s, and then when ZK-EVMs are mature, turn it inwards to scale ethereum L1 gas as well. Big congrats to the Ethereum researchers and core devs who worked hard for years to make this happen.







Below we attach the arc of Ethereum as we see it. Critical steps to win include: 1. Scaling L1 & DA in order to keep fees low & continue winning the customers 2. Hardening & talking about Ethereum’s security Solving the L2<>L2 interop to expand liquidity moat




0/ I believe that 2026 will be the golden year for Ethereum privacy. That's especially true when it comes to enterprises. Here’s how the Ethereum ecosystem is leading the way and why that matters for institutions. A guest thread by @pbrody from @EYnews and @EntEthAlliance.



Monthly transaction count for Ethereum L1 & L2s. L2s expand @ethereum's reach & network effect. The combined throughput of the L1 & L2s is at an all-time high, with ~800m transactions processed in October.
