This issue was discovered with fuzzing. Panic 1: It was possible to assign a variable to a function/opcode with no return type. This caused a index-out-of-bounds panic when the analyzer attempted to access the first element of an empty vector of return types. The analyzer now presents an error when a .zk author attempts to assign a variable to an opcode that has no return types. Panic 2: There was an index-out-of-bounds panic when performing verification on Literals that were passed to Opcodes that use Array types as their arguments. This was fixed by pasting the validation code from the Variable verfication section which handles Arrays properly. (Refactoring should be done to reduce duplication here.)

About DarkFi
DarkFi is a new Layer 1 blockchain, designed with anonymity at the forefront. It offers flexible private primitives that can be wielded to create any kind of application. DarkFi aims to make anonymous engineering highly accessible to developers.
DarkFi uses advances in zero-knowledge cryptography and includes a contracting language and developer toolkits to create uncensorable code.
In the open air of a fully dark, anonymous system, cryptocurrency has the potential to birth new technological concepts centered around sovereignty. This can be a creative, regenerative space - the dawn of a Dark Renaissance.

Follow the installation instructions for the P2P IRC daemon.
Build
This project requires the Rust compiler to be installed. Please visit Rustup for instructions.
You have to install a native toolchain, which is set up during Rust installation, nightly toolchain and wasm32 target. To install nightly toolchain, execute:
% rustup toolchain install nightly
To install wasm32 target, execute:
% rustup target add wasm32-unknown-unknown
% rustup target add wasm32-unknown-unknown --toolchain nightly
Minimum Rust version supported is 1.67.0 (stable).
The following dependencies are also required:
| Dependency | Debian-based |
|---|---|
| git | git |
| make | make |
| gcc | gcc |
| pkg-config | pkg-config |
| alsa-lib | libasound2-dev |
| openssl | libssl-dev |
| sqlcipher | libsqlcipher-dev |
Users of Debian-based systems (e.g. Ubuntu) can simply run the following to install the required dependencies:
# apt-get update
# apt-get install -y git make gcc pkg-config libasound2-dev libssl-dev libsqlcipher-dev
Alternatively, users can try using the automated script under contrib
folder by executing:
% sh contrib/dependency_setup.sh
The script will try to recognize which system you are running, and install dependencies accordingly. In case it does not find your package manager, please consider adding support for it into the script and sending a patch.
To build the necessary binaries, we can just clone the repo, checkout to the latest tag, and use the provided Makefile to build the project:
% git clone https://github.com/darkrenaissance/darkfi
% cd darkfi && git checkout v0.4.1
% make
Development
If you want to hack on the source code, make sure to read some introductory advice in the DarkFi book.
Install
This will install the binaries on your system (/usr/local by
default). The configuration files for the binaries are bundled with the
binaries and contain sane defaults. You'll have to run each daemon once
in order for them to spawn a config file, which you can then review.
# make install
