@qdrvm_io @ReamLabs @ethereumfndn devnet-3 in feb - forsure

QLEAN client is among the first amazing lean consensus clients reaching devnet-2 interop introducing PQ-signatures aggregation. Our team is already working together with amazing engineers from @zeamETH , @ReamLabs , and @ethereumfndn to ship spec for upcoming devnet-3 which is going to introduce aggregator role and committee aggregation

9) Increasing the parachain slot does not necessarily reduce the block production rate. Thanks to the recent block bundling feature, multiple parachain blocks can be produced and submitted together in a single batch for relay chain verification once per parachain slot x.com/paritytech/sta…

We conducted a case study on collator isolation attack in @Polkadot network + mitigation to enable single-honest collator parachains using Shadow network simulator 🧵👇

We are keeping track of networking performance in @leanEthereum devnets. In the following report we analyzed devnet-1 by spinning up networks of 64, 128, and 256 qlean validators and measured attestation and blocks propagation speeds @kamilsa/rJl-K-WeQ-g" target="_blank" rel="nofollow noopener">hackmd.io/@kamilsa/rJl-K…

Quadrivium's QLEAN integrated Post-Quantum signatures into 3SF-mini consensus pipeline and achieved interop with Zeam and Ream implementations for the upcoming @leanEthereum consensus devnet 1!

Craaazy 365 days of @leanEthereum progress. Cheers to the builders. Cheers to the dreamers. Cheers to anti-fragility, too :) Devcon, Bangkok — Nov 12, 2024. The suspense is real. The room overflows; hundreds can't get in. An "announcement of an announcement" had sparked wild speculation about my "most ambitious initiative". Who knew the beam chain vision would evolve into lean Ethereum? Next-level ambition, seeping into all layers of L1. Snarks for consensus and execution. Fort mode and beast mode. What's new? zkEVMs. Real-time proving. Full validation in a tab, on a phone. Let's pump L1 gas with the exponential snark curve. Starting in months, not years. To me it all points to 10K TPS, the gigagas frontier. Dream bigger dreams for L1. Believe in something. ——— part 1—lean consensus devnets → clients: 4 new lean CL clients (Zeam, Ream, Qlean, Lantern) → languages: 3 new CL languages (Zig, C++, C) → specs: by @tcoratger + 14 others; 3SF-mini subspec by @vitalikbuterin → testing: revamped test framework by @fselmo2; @Sib_Katya metrics → devnets: multi-client 3SF with 4s slots and 12s finality; PQ soon™ coordination → hires: EF Protocol coordinators @corcoranwill and @ladislaus0x → CL teams: led by @Gajpower, @unnawut, @kamil_abiy, @mstore80 → 7 consensus calls: teams, PQ, p2p, exit queue, APS, 3SF, PQ specs → Cannes workshop: 1 day at EthCC in June; interop kicked off → 13 interop calls: by @corcoranwill on Wednesdays at 2pm UTC → Cambridge Oct workshops: 1 day leanVM, 3 days PQ, 3 days CL cryptography → leanSig: 3 papers on hash sigs by Benedikt, @khovr, @kudinov_mikhail → leanVM: fast minimal aggregation zkVM by Emile → WHIR: fast Plonky3 implementation by @tcoratger → optimisoors: @AngusGruen, @GiacomoFenzi, @lambdaclass, @kiliconu → Poseidon2: 4 cryptanalysis workshops by @khovr, @asanso → maths: $1M Millennium-like proximity prize; papers flowing → formal verification: ArkLib by @QuangVDao research → consensus team: hires @yannvon and lead @robsaltini join @luca_zanolini → faster finality: 1- or 2-round designs with Ethereum-grade liveness → 3sf-gold: new fast inclusion by @fradamt, @vitalikbuterin from Cambridge → p2p: @qdrvm_io simulator; @raulvk ethp2p; @soispoke leanp2p → rainbow staking: new Cambridge ideas; specs by Dan Goron & Alex Vlad ——— part 2—lean execution zkEVM tech → real-time proving: ~100 engineers pushing across ~10 zkVM teams → GPU proving: 16 5090s (10kW) proving mainnet; $0.01/block → guests: revm (Reth), levm (Ethrex), evmone (Zilkworm), ZKSync OS → more guest programs: Geth, Besu, Nethermind and others soon™ → RISC-V: de facto ISA of choice for zkEVM proving → Picus: prolific Veridise tool to identify under-constraints → formal verification: $4M across 40 grants by @alexanderlhicks Ethproofs community → zkVM integrations: Airbender, OpenVM, Pico, R0VM, SP1, Ziren, ZisK → other integrations: Cysic, Fermah, Marlin, Snarkify, Zilkworm, ZkCloud → website: driven by @fbwoolf under new EF Ethproofs team → 7 calls: zkVMs, RTP, gigagas, RISC-V, native rollups, proximity gaps → Ethproofs day: Nov 22 at Devconnect; register at ethproofs[.]day → zkAttester demo: my home validator on zkEVM proofs at Ethproofs day EF zkEVM team → new team: led by @kevaundray with Cody, Han, Ignacio, Radek, Sophia → EF blog post: real-time proving requirements by @_sophiagold_ → zkLighthouse: modified Lighthouse client by @kevaundray → zkEVM/acc: @ignaciohagopian benchmarks; @codytouchgrass tests → more zkEVM/acc: @kevaundray standardisation; Ere by @han__0110 future of EL → Fusaka: per-tx gas limit (EIP 7825); MODEXP killer (EIPs 7823, 7883) → EVM 2.0: @vitalikbuterin proposal to enshrine RISC-V under the EVM → native rollups: championed by @lucadonnoh; wrote book and draft EIP → gas auto-pumps: 3x/year gas pumps (EIP-7938 by @dankrad) → gigagas L1: champion wanted—reach out :) gigagas@ethereum.org

QLEAN – a lean Ethereum consensus client written in C++ by Quadrivium team – achieved multi-client interoperability with with Ream and Zeam implementations, together reaching 3SF-mini consensus 🚀

11/ We consider our simulator to be a useful tool to check how practical different networking and compute assumptions may be for the post-quantum transition. Feel free to use it to test your assumptions! The full report explains how to reproduce our result

10/ Using the Aggregators-only Grid, 200Mbps bandwidth, and doubling the recursive SNARK rate to 20/sec, we achieved a final aggregation time of just 2.3 seconds

🧵 We're excited to share our report on simulation of Post-Quantum (PQ) signature aggregation! @kamilsa/ry3sOVBLex" target="_blank" rel="nofollow noopener">hackmd.io/@kamilsa/ry3sO… With support from an @ethereumfndn grant we investigated requirements needed to aggregate thousands of signatures within a four-seconds lean consensus slot
