Thanks for your interest in joining the mission to accelerate the mass adoption of crypto for personal 4 | sovereignty! We welcome contributions from anyone on the internet. 5 | 6 | Note, however, that all the contributions are subject to review, and not every contribution is guaranteed to be merged. 7 | It is highly advised to reach out to developers (for example, by creating an issue) before preparing a significant 8 | change in the codebase, and explicitly confirm that this contribution will be considered for merge. Otherwise, it is 9 | possible to discover that a feature you have spent some time on does not align with the core team vision or capacity to 10 | maintain a high quality of given submission long term. 11 | 12 | ## Ways to contribute 13 | 14 | There are many ways to contribute to the ZK Stack: 15 | 16 | 1. Open issues: if you find a bug, have something you believe needs to be fixed, or have an idea for a feature, please 17 | open an issue. 18 | 2. Add color to existing issues: provide screenshots, code snippets, and whatever you think would be helpful to resolve 19 | issues. 20 | 3. Resolve issues: either by showing an issue isn't a problem and the current state is ok as is or by fixing the problem 21 | and opening a PR. 22 | 23 | ## Fixing issues 24 | 25 | To contribute code fixing issues, please fork the repo, fix an issue, commit, add documentation as per the PR template, 26 | and the repo's maintainers will review the PR. 27 | 28 | ## Licenses 29 | 30 | If you contribute to this project, your contributions will be made to the project under the MIT OR Apache-2.0 31 | license. 32 | 33 | ## Resources 34 | 35 | We aim to make it as easy as possible to contribute to the mission. This is still WIP, and we're happy for contributions 36 | and suggestions here too. Some resources to help: 37 | 38 | 1. [In-repo docs aimed at developers](docs) 39 | 40 | 41 | ## Code of Conduct 42 | 43 | Be polite and respectful. 44 | 45 | ## FAQ 46 | 47 | **Q**: I have a small contribution that's not getting traction/being merged? 48 | 49 | **A**: Due to capacity, contributions that are simple renames of variables or stylistic/minor text improvements, one-off 50 | typo fix will not be merged. 51 | 52 | ### Thank you 53 | -------------------------------------------------------------------------------- /examples/memory-test/src/main.rs: -------------------------------------------------------------------------------- 1 | #![no_std] 2 | #![no_main] 3 | 4 | use core::panic::PanicInfo; 5 | 6 | #[panic_handler] 7 | fn panic(_info: &PanicInfo) -> ! { 8 | loop {} 9 | } 10 | 11 | #[no_mangle] 12 | pub extern "C" fn _start() -> ! { 13 | // Test memory operations: loads and stores 14 | 15 | // 1.

Executive Summary 4 | 5 | **zp1** is designed as a next-generation Zero-Knowledge Virtual Machine (zkVM) targeting specific performance metrics: 6 | - **Proving Speed**: Maximized via small fields (Mersenne-31) and hardware acceleration (GPU/Metal). 7 | - **Soundness**: Ensuring 128-bit security via QM31 extension and DEEP-ALI STARKs. 8 | - **Developer Experience**: Standard RISC-V support allowing Rust/C++ guest programs. 9 | 10 | The system leverages **Circle STARKs** over the **Mersenne-31 (M31)** field, which allows for highly efficient arithmetic on standard CPUs/GPUs while avoiding the overhead of larger prime fields (like Goldilocks or BabyBear) or elliptic curves (like BN254). 11 | 12 | --- 13 | 14 | ## 2. System Architecture Overview 15 | 16 | The system follows a standard **Compiler -> VM -> Prover -> Verifier** pipeline. 17 | 18 | ![zkVM Architecture Mind Map](docs/zkvm_mindmap.png) 19 | 20 | --- 21 | 22 | ## 3. Detailed Data Flow Architecture 23 | 24 | The data flow moves from a high-level Rust program to a verifiable cryptographic proof. 25 | 26 | ![zkVM Data Flow](docs/zkvm_dataflow.png) 27 | 28 | --- 29 | 30 | ## 4. Key Architectural Decisions & Logic 31 | 32 | ### 4.1. The Field Choice: Mersenne-31 (M31) 33 | **Why?** 34 | - **Performance**: M31 ($2^{31}-1$) fits into a 32-bit register. Addition requires an integer add with a conditional subtract (or bitwise AND). Multiplication fits in a 64-bit word before reduction. This can be faster than Goldilocks ($2^{64}-2^{32}+1$) or BabyBear on some 32-bit/64-bit hardware. 35 | - **GPU Friendly**: GPUs excel at 32-bit arithmetic. M31 is native to GPU ALUs. 36 | 37 | **Implication**: 38 | - Conventional FFTs require domains of size $2^n$. M31 is a Mersenne prime, so $M31 - 1$ is not highly divisible by 2. We cannot use standard FFTs efficiently. 39 | - **Solution**: **Circle FFT**. We work over the circle group $x^2 + y^2 = 1$ in M31. This group has size $2^{31}$, allowing efficient FFTs of any power-of-two size. 40 | 41 | ### 4.2. Lookup Arguments: LogUp vs. Lasso 42 | **Current State**: The system uses `LogUp`. 43 | **Constraint Logic**: 44 | - Instead of proving every bitwise operation (AND, XOR) with expensive polynomial equations (e.g., $a \cdot (1-a) = 0$ for 32 bits), we use **Lookup Tables**. 45 | - We compute $a \oplus b = c$. We check if the tuple $(a, b, c)$ exists in a precomputed "XOR Table". 46 | - **LogUp** converts this lookup check into a sum of rational functions: $\sum \frac{1}{x - t_i} = \sum \frac{m_i}{x - T_i}$. 47 | - **Optimization**: This dramatically reduces degree of constraints for bitwise operations, which are dominant in SHA-256 and Keccak. 48 | 49 | ### 4.3. Precompiles & Acceleration 50 | **Design Goal**: syscalls for heavy crypto. 51 | - Instead of running SHA-256 as 10,000 RISC-V instructions, the VM traps the execution. 52 | - The **Executor** computes the hash natively. 53 | - A dedicated **Chip (Table)** is filled with the input/output trace of the hash. 54 | - The **Prover** proves the Chip validity separately and connects it to the main CPU bus via Lookups. 55 | 56 | --- 57 | 58 | ## 5. Logical Gap Analysis: Improvements Needed 59 | 60 | | Feature | Current Status | Recommended Upgrade | Why? | 61 | | :--- | :--- | :--- | :--- | 62 | | **Recursion** | `snark` wrappers exist | **Segmented STARK Recursion** | To prove long programs, split trace into N segments. Recursively prove each segment into a single proof. | 63 | | **Memory** | Basic consistency | **Paged Memory / Write-once** | For massive memory usage, simpler access patterns or "memory-as-external-lookup" can save constraints. | 64 | | **GPU Acceleration** | ✅ Native Metal kernels | **CUDA Parity** | Metal NTT/LDE implemented; CUDA kernels need runtime integration. | 65 | 66 | --- 67 | 68 | ## 6. Visualizing the "Circle STARK" Logic 69 | 70 | Why Circle STARKs specifically? 71 | 72 | ```mermaid 73 | flowchart LR 74 | subgraph TS["Traditional STARK"] 75 | F["Field Fp"] -->|"Multiplicative Subgroup"| D["Domain size 2^n"] 76 | D -->|"Requires p-1 divisible by 2^n"| Limit["Limits Field Choice"] 77 | end 78 | 79 | subgraph CS["Circle STARK"] 80 | M31["Mersenne 31"] -->|"Circle Group x^2+y^2=1"| C["Circle Domain"] 81 | C -->|"Size = p+1 = 2^31"| Anypow["Fits ANY power of 2"] 82 | Anypow -->|"Fast Arithmetic"| Speed["Max Performance"] 83 | end 84 | ``` 85 | 86 | Using M31 provides efficient integer math on CPUs/GPUs, but breaks traditional FFTs.

Guest programs can perform computations, invoke cryptographic precompiles, and commit results to the public journal. 8 | 9 | ## Features 10 | 11 | - **I/O Operations**: Read inputs from host, commit outputs to public journal 12 | - **Cryptographic Precompiles**: Keccak256, SHA256, ECRECOVER, RIPEMD160, Blake2b, MODEXP 13 | - **no_std Compatible**: Works in bare-metal RISC-V environment 14 | - **Easy Entry Point**: Simple macro for guest program setup 15 | 16 | ## Usage 17 | 18 | ### Basic Guest Program 19 | 20 | ```rust 21 | #![no_std] 22 | #![no_main] 23 | 24 | use zp1_zkvm::prelude::*; 25 | 26 | #[no_mangle] 27 | fn main() { 28 | // Read inputs from host 29 | let a: u32 = read(); 30 | let b: u32 = read(); 31 | 32 | // Perform computation 33 | let sum = a + b; 34 | 35 | // Commit output to public journal 36 | commit(&sum); 37 | } 38 | 39 | // Set up entry point and panic handler 40 | zp1_zkvm::entry!(main); 41 | ``` 42 | 43 | ### Using Cryptographic Precompiles 44 | 45 | ```rust 46 | #![no_std] 47 | #![no_main] 48 | 49 | use zp1_zkvm::prelude::*; 50 | 51 | #[no_mangle] 52 | fn main() { 53 | // Read transaction data 54 | let data: Vec = read(); 55 | 56 | // Compute Keccak256 hash (delegated to precompile) 57 | let hash = keccak256(&data); 58 | 59 | // Compute SHA256 hash 60 | let sha_hash = sha256(&data); 61 | 62 | // Commit both hashes 63 | commit(&hash); 64 | commit(&sha_hash); 65 | } 66 | 67 | zp1_zkvm::entry!(main); 68 | ``` 69 | 70 | ### ECRECOVER Example 71 | 72 | ```rust 73 | #![no_std] 74 | #![no_main] 75 | 76 | use zp1_zkvm::prelude::*; 77 | 78 | #[no_mangle] 79 | fn main() { 80 | // Read signature components 81 | let msg_hash: [u8; 32] = read(); 82 | let v: u8 = read(); 83 | let r: [u8; 32] = read(); 84 | let s: [u8; 32] = read(); 85 | 86 | // Recover Ethereum address from signature 87 | match ecrecover(&msg_hash, v, &r, &s) { 88 | Some(address) => { 89 | commit(&address); 90 | } 91 | None => { 92 | // Invalid signature 93 | commit(&[0u8; 20]); 94 | } 95 | } 96 | } 97 | 98 | zp1_zkvm::entry!(main); 99 | ``` 100 | 101 | ## Compilation 102 | 103 | Guest programs must be compiled to the `riscv32im-unknown-none-elf` target: 104 | 105 | ```bash 106 | # Add the target (one time setup) 107 | rustup target add riscv32im-unknown-none-elf 108 | 109 | # Compile your guest program 110 | cargo build --target riscv32im-unknown-none-elf --release 111 | ``` 112 | 113 | The resulting ELF binary can be executed and proven by the ZP1 zkVM. 114 | 115 | ## API Reference 116 | 117 | ### I/O Functions 118 | 119 | - **`read()`** - Read typed input from host 120 | - **`commit(value)`** - Commit output to public journal 121 | - **`hint(value)`** - Provide unverified hint to prover 122 | - **`print(msg)`** - Debug output (not verified) 123 | 124 | ### Cryptographic Functions 125 | 126 | - **`keccak256(data: &[u8]) -> [u8; 32]`** - Keccak-256 hash 127 | - **`sha256(data: &[u8]) -> [u8; 32]`** - SHA-256 hash 128 | - **`ecrecover(hash, v, r, s) -> Option<[u8; 20]>`** - Ethereum signature recovery 129 | - **`ripemd160(data: &[u8]) -> [u8; 20]`** - RIPEMD-160 hash 130 | - **`blake2b(data: &[u8]) -> [u8; 64]`** - Blake2b hash 131 | - **`modexp(base, exp, mod) -> [u8; 32]`** - Modular exponentiation 132 | 133 | ### Entry Macro 134 | 135 | ```rust 136 | zp1_zkvm::entry!(main); 137 | ``` 138 | 139 | Sets up the RISC-V entry point (`_start`) and panic handler for your guest program. 140 | 141 | ## Implementation Status 142 | 143 | ### ✅ Implemented 144 | 145 | - Library structure and API 146 | - Syscall definitions (inline assembly) 147 | - Entry point macro 148 | - no_std compatibility 149 | - Documentation 150 | - I/O functions (read, commit, hint) with syscall protocol 151 | - Raw byte I/O variants (read_slice, commit_slice, hint_slice, peek_input_size) 152 | 153 | ### 🚧 In Progress 154 | 155 | - Host-side I/O syscall handlers in executor 156 | - Integration testing with actual guest programs 157 | 158 | ### 📋 Planned 159 | 160 | - More precompiles (BN254, BLS12-381, Ed25519) 161 | - Alloc support for dynamic memory 162 | - Standard library compatibility mode 163 | - Debugging utilities 164 | 165 | ## Architecture 166 | 167 | Guest programs invoke syscalls via the RISC-V `ECALL` instruction: 168 | 169 | 1. Set syscall code in register `a7` (x17) 170 | 2. Set arguments in registers `a0-a6` (x10-x16) 171 | 3. Execute `ECALL` 172 | 4. Return value in `a0` (x10) 173 | 174 | The executor intercepts ECALL instructions and dispatches to the appropriate handler (precompile circuits, I/O operations, etc.). 175 | 176 | ## Security Considerations 177 | 178 | - **Deterministic Execution**: Guest programs must be deterministic 179 | - **No Side Effects**: No file I/O, network, or system calls (except provided syscalls) 180 | - **Memory Safety**: Use Rust's safety guarantees 181 | - **Hint Data**: Never trust `hint()` data - always verify within guest 182 | 183 | ## Examples 184 | 185 | See `examples/` directory for complete guest program examples: 186 | 187 | - `fibonacci` - Simple recursive computation 188 | - `keccak_hash` - Cryptographic hashing 189 | - `signature_verify` - ECRECOVER signature verification 190 | 191 | ## License 192 | 193 | See workspace license. 194 | -------------------------------------------------------------------------------- /crates/executor/tests/test_keccak.rs: -------------------------------------------------------------------------------- 1 | //!
