With our 0.17 release, we have expanded our Bonsai content and updated the installation process. The latter change means existing users will have to install again when upgrading, by running cargo install cargo-risczero and cargo risczero install. See the Getting Started section of our README for prerequisites and more details. We've also added a developer mode for more rapid development and continued to streamline the proof and receipt APIs, among other changes.

Thank you to community members @criadoperez, @austinabell, and @roseiliend for their contributions to this release!
​

Important and Breaking Changes

  • Added a cargo risczero install tool for setting up the RISC Zero toolchain. Fixes in this release require a "risc0" rustup toolchain; the cargo risczero install command will install this toolchain and do other RISC Zero setup. All users, new and old, will need to run this command to install the RISC Zero zkVM. Full details are available in the Getting Started section of our README.
  • Added a Developer Mode enabling more rapid development by skipping proving and validation steps. No proof is generated or verified while in developer mode, and in particular running verification in developer mode provides no security whatsoever. The RISC0_DEV_MODE environment variable controls whether developer mode is enabled, and this feature can be fully disabled at build time, regardless of environment, by using the disable-dev-mode feature flag on the risc0-zkvm crate.
  • Streamlined the Receipt, Executor, and Prover APIs. A basic high-level usage now looks like let receipt = default_prover().prove_elf(env, SOME_ELF).unwrap();. Receipt implementation details are encapsulated in an InnerReceipt object which most users will not need to interact with. The Prover now has additional high level methods, included prove and prove_elf. See the Executor, Receipt, and Prover sections of our docs for the current API, and this PR for details about the changes.
  • Moved binary format functionality into a separate risc0-binfmt crate. See its docs for details.
  • Prevented guest from writing to memory that will crash the prover if tampered with. See this PR for details.
  • Fixed large I/O and prevent splitting to a new segment when no instructions have been run. See this PR for details.
  • Updated circuit as well in the previous PR as well as this PR.
  • Pinned the cc crate to a specific version as a workaround to build problems when using its latest version.
  • Adjusted the Bonsai Ethereum Relay in several ways, including websockets, Solidity CI, SNARK seal support, and verify interface
