@nazarpc (BTW, I love what little I understand of RVV, and in particular I think it would be a better fit for BLAKE3 than current SIMD designs.)

@nazarpc And the other thing about A being behind B at time T0 is that even if, at time T1, A has caught up to where B was at T0, then B may also have moved on.

Very cool! I remain convinced that wasm is going to turn out to be better than RISC-V for ZK proving. In addition to the reasons that Lumi mentions here, wasm is also more widely supported than RISC-V is. For example, BLAKE3/wasm > BLAKE3/RISC-V.

This is exciting work from @powdr_labs: ~1.5x speedup & a 5x-6x reduction in memory from ZK proving WASM instead of RISC-V 🔥 (and this is without circuit optimizations, autoprecompiles, etc) While most zkVMs currently prove the RISC-V ISA because of advantages like a limited instruction set, it is far from obvious RISC-V will continue to be the winner in the long term. It’s worth keeping in mind how new the field of zkVMs is: @RiscZero released the first production grade zkVM only in 2022, and commercially viable real-time mainnet EVM proving was only just achieved earlier in 2025 by @SuccinctLabs This is why we at @Offchain proposed that @ethereum L1 should use WASM as the delivery ISA instead of RISC-V. WASM is designed as intermediate abstraction layer rather than the final execution target. WASM as a dISA can allow smart contract proving (including proving on RISC-V or WASM or other more ZK friendly ISAs), programming, and execution to evolve freely, rather than constraining each other. This is separation of a delivery ISA from a proving ISA is what we already do today for ZK proving @Arbitrum with Succinct’s SP1 Hypercube. By compiling WASM code into RISC-V code, we are able to ZK-prove not only the core Arbitrum STF, but also user-supplied Arbitrum Stylus smart contracts written for WASM (including Rust, C/C++, Move, AssemblyScript based programs)

Useful framework.
CipherScan's multi-network architecture already supports this, adding a new network is a config change, not a code fork.
We've integrated Crosslink finality into the codebase and are ready to deploy explorer instances for Feature Nets and Upgrade Candidates as their networks go live.

We found the same Fiat-Shamir bug in six independent zkVMs. The result: an attacker can bypass the cryptography entirely and prove mathematically impossible statements (like minting $1M out of thin air). Full breakdown ↓

@ccatalini @intangiblecoins Yeah! Your filtering is part of your mind.

this website is overridden with slop
is this the trough were meant to feed at?
honestly i wonder. there will be a trough
x might be it. it’s getting very bad

@AmandaAskell If it makes you feel any better, this tweet of yours is the first I’ve heard about you having ever been married. 😊
English
Perhaps I should get married again so that the media has a more recent man they can reference any time they mention me or my work.

"If Nobody Builds It, Everybody Dies!"
My upcoming book about how only ASI (Artificial Super Intelligence) will be smart enough to predict the potentially world ending results of ultra high energy physics experiments, before we blindly try them and destroy ourselves.

@ccatalini @intangiblecoins I already have one. It’s my follow list. (You’re on it.) Any great verification filter that filters for everyone instead of filtering for each person individually or for many small groups will do far more harm than good.

Paul Ehrlich died, may the man rest in peace - but his insane ideas live on and will keep haunting us.

Paul Ehrlich in 1970: "The FCC should see to it that large families are always treated in negative light on television."
If that doesn't work, then the government should "legislate the size of the family" and "throw you in jail if you have too many" kids.
