zkVM RISC-V

@openvm_org released OpenVM 2.1 Preview with 64-bit RISC-V and native recompilation, enabling real-time Ethereum block proving on four RTX 5090 GPUs. It is unaudited and not recommended for production.

Notes Notes 要点

Four RTX 5090 GPUs proved 7,200 mainnet blocks with 9.7s p99 and 5.0s average latency.
Sixteen GPUs reached 3.7s p99 and 2.4s average, with live proofs submitted to EthProofs.
RV64IM_Zicclsm support aligns with the Ethereum Foundation zkVM target and supports Rust, C++, and Go.
The 64-bit word size can lower Ethereum proving cost and supports misaligned memory accesses.
Native recompilation emits portable C and runs 34x faster than the fast interpreter.
End-to-end STARK proofs target 100-bit provable security and remain below 300kB.

What is new in 2.1?

It adds 64-bit RISC-V, RV64IM_Zicclsm compatibility, and portable-C native recompilation.

Why adopt 64-bit RISC-V?

It matches the EF zkVM target, broadens language support, and may handle 256-bit EVM words more efficiently.

How does native recompilation work?

The prover lifts the guest executable into portable C, then compiles it into a native host CPU library.
