Why aren't we voting on the zkEVM yet? The zkEVM stack solves core the challenge of digital voting: ZK proofs enable secure vote verification, while the EVM ensures integrity. With zkRollups like Scroll, it can process millions of votes instantly at a very low cost, which is enough for national elections. Think of it as a digital ballot box: anonymous yet verifiable. Votes are EVM state transitions, with ZK proofs checking eligibility privately and ensuring integrity. Smart contracts count transparently and L1 provides immutable records. These cryptographic systems are battle-tested through DeFi. While technically sound, we still need better digital identity, UX, and regulations. But account abstraction and ZK advances are closing these gaps fast. The infrastructure exists: zkEVM could revolutionize democratic participation like TCP/IP did for information. The question is when, not if! Adapted from a blog post by our co-founder Sandy: https://sandypeng.substack.com/p/why-arent-we-voting-on-the-blockchain

the blob data is interpreted as 4096 numbers and then that's treated as a 4096-degree polynomial and that's what's used to compute the KZG commitment then the commitment gets hashed to keep the EVM happy with 32 bytes

yeah they do a quick check that the KZG commitment matches the one in the transaction, then once they received the whole blob content they're satisfied that `is_data_available == true` and are ready to attest to the block (after all the other usual checks ofc)

with full danksharding, nodes wont have to download those big blocks, just do a few samples and then they're satisfied that the data is available – full download is optional, but possible for those who need the data

The possibility is definitely there, i expect it'll be discussed more after the upgrade goes through

The quantum proof one would likely involve FRI (the polynomial commitment scheme used in STARKs), FRIDA is a potential candidate, though at this point I don't know how suitable it is for Ethereum's purposes: https://eprint.iacr.org/2024/248

Vitalik talks about alternative commitment schemes here: https://notes.ethereum.org/@vbuterin/proto_danksharding_faq#Couldn%E2%80%99t-we-use-some-other-commitment-scheme-without-a-trusted-setup It's still an active area of research, we know quantum computing can break KZG so we'll want to switch eventually

You can't do that at the protocol level, but it's possible to construct a "blob sharing protocol" to have smaller L2s combine batches to avoid having to pay for an entire blob that they can't fill as fast as bigger rollups: https://hackmd.io/@dapplion/blob_sharing

It's basically impossible to say at this point, the 3 blobs/block target from today will increase to 256 blobs/block with full danksharding, but it probably won't result in 83x lower fees on L2s. It's all about how L2s handle that data and if there's enough demand to fill up L1's blobspace

Possibly as early as next fork if we can implement PeerDAS. Not sure by how many blobs though At the very least it won't take long to have data on how mainnet handles the blobs and see if we can increase blob count safely even without PeerDAS
