@SEJeff @full_kelly_ @toly We would be interested in getting the mechanism audited for everyone's benefit, but we need a sugar daddy for that

Overclock | Solana Validator retweeted
In order for 20 market makers to reliably quote JUST the S&P500 members at 10 quotes per second, the chain needs to support 100k oracle updates per second. with the fd runtime, oracle updates execute with a mode of about 15 micros (load, execute, commit). verifying these signatures cost approximately 19 micros — more than the time it takes to execute — until now!!! this optimization is a HUGE step toward making Solana the house of all finance.

9/ Across 8 cores we measured 1.217M signatures/s, short of 8× the single-core rate because all-core AVX-512 drops the clocks.
Thank you to @Allnodes for giving us a free Ryzen server rental to test these Zen5 benchmarks on!
1/ Ed25519 verification is a major cost in Solana block replay. Mithril is written in Go, and the standard Go library wasn't enough for the throughput we wanted. Today we're releasing narya-ed25519. 5.8× faster than crypto/ed25519 at 4.7 µs/sig (Zen5). github.com/Overclock-Vali…
11/ Narya is alpha and unaudited, and the AVX-512 backend is opt-in rather than automatic. We differential-test against Go's stdlib and curve25519-voi, run the CCTV and Wycheproof suites, and fuzz, but it still needs independent review. Apache-2.0, attributions in NOTICE.
10/ Regarding our work here, we want to say thank you to our AI overlords. AI was deeply involved in the R&D (Codex, ChatGPT Pro, Claude) and helped explore code, analyze profiles/math, generate hypotheses and tests, write docs, and implemented all the code including assembly.

@fPHXGallery @toly It will use more, but maybe around 8 GB. We will see if we need to change things to be competitive enough with the other validator clients though. A professional validator setup should use more substantial hardware regardless.
Okay, Mithril validator is running at less than 3GB RAM on the Alpenglow cluster with a small Ryzen. We just need some of your state compression ideas implemented so that we don't need to plug a NVME into the phone when we have Mainnet state to deal with. The massive 50k tps synthetic blocks on ag cluster will also be challenge for a phone...
@toly Is this in the plans at all? @bw_solana
@BloodReaver The real hardware requirement comparison will be once our Alpenglow version hits Mainnet... but it should still be good. Agave's hardware requirements have also trended down over time by quite a bit. On Alpenglow testnet cluster, Agave is using around 6 GB RAM last time we saw.
1/ Mithril v0.1.0-frodo is here: our independent Solana client written in Go is now an active validator on Alpenglow testnet, producing blocks, voting, and running full Alpenglow consensus. Try it via the alpenglow-dev branch: github.com/Overclock-Vali…
