@VitalikButerin ETH is painful to work with. Its junk

Now, the quantum resistance roadmap. Today, four things in Ethereum are quantum-vulnerable: * consensus-layer BLS signatures * data availability (KZG commitments+proofs) * EOA signatures (ECDSA) * Application-layer ZK proofs (KZG or groth16) We can tackle these step by step: ## Consensus-layer signatures Lean consensus includes fully replacing BLS signatures with hash-based signatures (some variant of Winternitz), and using STARKs to do aggregation. Before lean finality, we stand a good chance of getting the Lean available chain. This also involves hash-based signatures, but there are much fewer signatures (eg. 256-1024 per slot), so we do not need STARKs for aggregation. One important thing upstream of this is choosing the hash function. This may be "Ethereum's last hash function", so it's important to choose wisely. Conventional hashes are too slow, and the most aggressive forms of Poseidon have taken hits on their security analysis recently. Likely options are: * Poseidon2 plus extra rounds, potentially non-arithmetic layers (eg. Monolith) mixed in * Poseidon1 (the older version of Poseidon, not vulnerable to any of the recent attacks on Poseidon2, but 2x slower) * BLAKE3 or similar (take the most efficient conventional hash we know) ## Data availability Today, we rely pretty heavily on KZG for erasure coding. We could move to STARKs, but this has two problems: 1. If we want to do 2D DAS, then our current setup for this relies on the "linearity" property of KZG commitments; with STARKs we don't have that. However, our current thinking is that it should be sufficient given our scale targets to just max out 1D DAS (ie. PeerDAS). Ethereum is taking a more conservative posture, it's not trying to be a high-scale data layer for the world. 2. We need proofs that erasure coded blobs are correctly constructed. KZG does this "for free". STARKs can substitute, but a STARK is ... bigger than a blob. So you need recursive starks (though there's also alternative techniques, that have their own tradeoffs). This is okay, but the logistics of this get harder if you want to support distributed blob selection. Summary: it's manageable, but there's a lot of engineering work to do. ## EOA signatures Here, the answer is clear: we add native AA (see eips.ethereum.org/EIPS/eip-8141 ), so that we get first-class accounts that can use any signature algorithm. However, to make this work, we also need quantum-resistant signature algorithms to actually be viable. ECDSA signature verification costs 3000 gas. Quantum-resistant signatures are ... much much larger and heavier to verify. We know of quantum-resistant hash-based signatures that are in the ~200k gas range to verify. We also know of lattice-based quantum-resistant signatures. Today, these are extremely inefficient to verify. However, there is work on vectorized math precompiles, that let you perform operations (+, *, %, dot product, also NTT / butterfly permutations) that are at the core of lattice math, and also STARKs. This could greatly reduce the gas cost of lattice-based signatures to a similar range, and potentially go even lower. The long-term fix is protocol-layer recursive signature and proof aggregation, which could reduce these gas overheads to near-zero. ## Proofs Today, a ZK-SNARK costs ~300-500k gas. A quantum-resistant STARK is more like 10m gas. The latter is unacceptable for privacy protocols, L2s, and other users of proofs. The solution again is protocol-layer recursive signature and proof aggregation. So let's talk about what this is. In EIP-8141, transactions have the ability to include a "validation frame", during which signature verifications and similar operations are supposed to happen. Validation frames cannot access the outside world, they can only look at their calldata and return a value, and nothing else can look at their calldata. This is designed so that it's possible to replace any validation frame (and its calldata) with a STARK that verifies it (potentially a single STARK for all the validation frames in a block). This way, a block could "contain" a thousand validation frames, each of which contains either a 3 kB signature or even a 256 kB proof, but that 3-256 MB (and the computation needed to verify it) would never come onchain. Instead, it would all get replaced by a proof verifying that the computation is correct. Potentially, this proving does not even need to be done by the block builder. Instead, I envision that it happens at mempool layer: every 500ms, each node could pass along the new valid transactions that it has seen, along with a proof verifying that they are all valid (including having validation frames that match their stated effects). The overhead is static: only one proof per 500ms. Here's a post where I talk about this: ethresear.ch/t/recursive-st… firefly.social/post/farcaster…

@Credib1eGuy @BasedShillBH lol

It’s quite clear $HYPE is going to several hundred dollars at this point Matter of when, not if. Tbh I recommend not trying to catch the bottom, will likely be violent lock out trend at some point.

@TradeWithKobe Literally who gives a shit

Remember. I called the crypto crash of 2026 before anyone on the internet. On December 20, 2024. This channel is a hidden gem. Spread the word. Going to keep posting this until it gets the recognition it deserves, and this is only one of many predictions I've been correct on

@octoseaa Sup

I see a trade

@diegopavia02 lol and Mendoza doesn’t have his family in his corner?

Being a part of the Heisman ceremony last night as a finalist was such an honor. As a competitor, just like in everything I do I wanted to win. To be so close to my dream and come up short was painful. I didn’t handle those emotions well at all and did not represent myself the way I wanted to. I have much love and respect for the Heisman voters and the selection process, and I apologize for being disrespectful. It was a mistake, and I am sorry. Fernando Mendoza is an elite competitor and a deserving winner of the award. I have nothing but respect for his accomplishments as well as the success that Jeremiyah and Julian had this season. I’ve been doubted my whole life. Every step of my journey I’ve had to break down doors and fight for myself, because Ive learned that nothing would be handed to me. My family has always been in my corner, and my teammates, coaches and staff have my six. I love them — I am grateful for them. — and I wouldn’t want anything to distract from that. I look forward to competing in front of my family and with my team one more time in the ReliaQuest Bowl.

@intodotspace Who said it was impossible ? Never heard anyone saying that

Impossible is a skill issue.

What memecoin should I load a million dollars into next?

@DefiLlama submitted $100 for Llama Nodes well over 24 hours ago and nothing. Llama nodes support is very slow. At this point I don't want to use the product. Please return my funds.
