Build Status

shol'va is a tool for generating zero knowledge proofs of program execution, composed of

Usage

Note: shol'va does native tracing X86 Linux programs, and as a result is strictly limited to that architecture.

Dependencies

sholva is built using nix. It is recommended to use the Determinate Systems installer:

$ curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install

Building

mttn

$ nix build .#mttn

This builds:

Enter a shell with development dependencies:

$ cd mttn
$ nix develop .#mttn

Manual testing:

# build all the of the test binaries
$ make -C test elfs
# run the mttn self-tests
$ cargo test

tiny86

$ nix build .#tiny86

This builds:

Enter a shell with development dependencies:

$ cd tiny86
$ nix develop .#tiny86

Manual testing:

# test the full Tiny86 circuit test suite
$ make _test-tiny86
# test the Tiny86 circuit Clash components Haskell source
$ make _test-clash
# test the Tiny86 circuit Verilog components
$ make _test-verilog
# test the Tiny86 circuit Verilog components, isolating modules
$ SHOLVA_MODULES="alu syscall" make _test-verilog
# test the manual end-to-end test suite
$ make _test-pipeline

sv_circuit

$ nix build .#sv_circuit

This builds the sv-compositor binary, which takes a BLIF file (defining a single step of Tiny86) and trace artifacts as input and yields proof artifacts (currently, a SIEVE IR0 circuit, public input, and private input) as output.

Enter a shell with development dependencies:

$ cd sv_circuit
$ nix develop .#sv_circuit

Manual testing (from the development environment):

$ cargo test

Exploit Modeling

Uses a provided jdk build cross-compiled to 80386.
