igneum-labs b64a31c77f Proving fixtures: blocks of one, two and four shards at S_p from a private simnet, plus the v1 cut of the v0 blocks 
tools/prove-fixtures: a one-node simnet on ports 29300+ and a generator that lands bursts of equal-sized modexp calls, transfers and Counter increments in one chain block (blocks 338, 341, 344: 0.90, 1.80 and 3.60 S_p). block-56-transfers-3shards is a test cut at 200 pgas for the Mac CPU multi-shard check.

proving

Igneum proving v0 (3 October 2026): the first SP1 proof of an Igneum block. Plan and scope: docs/plans/proving-v0.md.

  • igneum-prove/: Cargo workspace. core (the block statement, a port of the execution layer's executor), program (the SP1 guest), host (execute, core, compressed modes; the versioned ProofSystem trait with the stub and the SP1 implementation in host/src/proof_system.rs), export (cuts a real block out of an igneum_exportSegments dump and checks the port against the node's state roots).
  • fixtures/: real simnet blocks, block-78-increment.json (the Counter increment(5) call) and block-56-transfers.json (three transfers).
  • windows-wsl2/: SETUP-PROVER.bat, PROVE-BLOCK.bat and the Linux scripts for the project lead's PC; make-package.sh builds the zip.

Build and run on a machine with the SP1 toolchain (curl -L https://sp1up.succinct.xyz | bash && sp1up):

cd proving/igneum-prove
cargo build --release -p igneum-prove-export
./target/release/igneum-prove-export ../../tools/evm-smoke/seq.json 78 ../fixtures/block-78-increment.json
cargo build --release -p igneum-prove-host            # add --features igneum-prove-host/cuda on Linux x86_64 with an NVIDIA card
./target/release/igneum-prove-host ../fixtures/block-78-increment.json --mode execute   # native check + cycle count
SP1_PROVER=cuda ./target/release/igneum-prove-host ../fixtures/block-78-increment.json --mode all --out results.json
