This is a pure rust implementation of various zkp components by the ZK-Garage team
This a library currently contains several modules
The plonk-core module is an implemention of the PLONK proving system, that leverages custom gates and lookups to significantly enhance performance and lower constraint count to optimise the generation of zero knowledge proofs. The backend of the plonk-core module is designed to be compatible with the arkworks suite. By leveraging the operations in arkworks we have optimised algebra and generic trait abstractions for curve types, allowing users to define their SNARK over different curves and, if applicabale, utilise embedded or pairing curves. The polynomial commitment scheme is also generic, which allows users to implement differing PCSs dependent upon particular needs.
The plonk-hashing module is set to contain several hashing algorithms, commencing with an optimised implementation of the Poseidon hashing algorithm generic for both plonk-style arithmetic representation and R1CS. Which will be extended but not limited to Reinforced Concrete and Blake2s.
The plonk-book is a module which contains a detailed overview of the working parts within a EC based ZKP system, with explanation of some of the characteristics particular to PLONK, e.g. Lagrange bases. There is a also a chapter on the construction of the PLONK algorithms, as well as an explanation of the implementations features and details specific to this repository.
First, you need to install mdbook command line tool used to create books with Markdown.
cargo install mdbook
You should also install Katex preprocessor which renders Latex equations into HTML at build time
cargo install --git "https://github.com/lzanini/mdbook-katex"
Then, you build the book as follows:
mdbook build
Last but not least, you can read the book by doing this command
mdbook serve --open
This will display the book in your default web browser after building it.

This crate includes a variety of features which will briefly be explained below:
-
parallel: Enablesrayonand other parallelisation primitives to be used and speed up some of the algorithms used by the crate and it's dependencies. -
asm: Enables inline-assembly implementations for some of the internal algorithms and primitives used by thearkworksdependencies of the crate. -
trace: Enables the Circuit debugger tooling. This is essentially the capability of using theStandardComposer::check_circuit_satisfiedfunction. The function will output information about each circuit gate until one of the gates does not satisfy the equation, or there are no more gates. If there is an unsatisfied gate equation, the function will panic and return the gate number. -
trace-print: Goes a step further thantraceand prints eachgatecomponent data, giving a clear overview of all the values which make up the circuit that we're constructing. The recommended method is to derive the std output, and the std error, and then place them in text file which can be used to efficiently analyse the gates.
There are two main types of documentation in this repository:
-
Crate documentation. This provides info about all of the functions that the library provides, as well as the documentation regarding the data structures that it exports. To check this, please feel free to go to the documentation page or run
make docormake doc-internal. -
Notes. This is a specific subset of documentation which explains the key mathematical concepts of PLONK and how they work with mathematical demonstrations. To check it, run
make docand open the resulting docs, which will be located under/target/doc/plonk/index.htmlwith your browser.Examples. Examples can be found in the
examplesfolder. Run them, e.g., viacargo run --example simple_circuit.
