# Mikan ๐: The ZK Friendly DA Layer for Bitcoin L2s
Mikan is a ZK-Rollup friendly data availability layer built on the Malachite consensus framework.
It provides strong data availability guarantees using STARK-friendly cryptographic primitives
without requiring a trusted setup.
It is design to be particularly friendly to ZK-Rollups, specifically on Bitcoin, by providing a DA layer that is
compatible with the FRI commitment scheme, and by eliminating the need for a trusted setup.
> Name origin ๐ (่ๆ):
>
> Officially known as a Citrus unshiu or unshiu mikan, mikan is a type of mandarin orange and citrus fruit that originated in southern Japan approximately 400 years ago.
>
> Bitcoin goes necessarily with the orange color, so naturally a DA layer for Bitcoin L2s should be orange, and the Japanese connection is a Satoshi style touch.

## ๐ง Key Features
- **No Trusted Setup**: Unlike solutions using KZG commitments, Mikan relies on transparent
cryptography based on the FRI protocol, eliminating the need for trusted setup ceremonies.
- **ZK-Friendly Proofs**: Mikan generates succinct proofs of data availability using the M31
field (Mersenne prime 2^31-1), which is STARK-friendly and can be efficiently verified
inside ZK proofs.
- **Fast Consensus**: Built on the Malachite BFT consensus framework, which provides
high throughput and quick finality.
## ๐ Architecture
Mikan consists of the following components:
1. **Consensus Layer**: Based on Malachite BFT, handling block production and agreement.
2. **Data Availability Layer**: Uses FRI commitments and proofs for data availability sampling.
3. **Network Layer**: Ensures quick propagation of proposal parts across the network.
4. **API**: Allows rollups to submit data and retrieve availability certificates.
### ๐ Cryptographic Components
- **FRI Protocol**: Fast Reed-Solomon Interactive Oracle Proof for data availability.
- **M31 Field**: Uses the Mersenne prime 2^31-1 for efficient field arithmetic.
- **Merkle Trees**: For efficient commitments and proofs.
The core primitives for the Data Availability Sampling are implemented in [FRI Extended for Data Availability: a FRI-based Data Availability Sampling library, written in Rust.](https://github.com/keep-starknet-strange/frieda).
## ๐ฎ Getting Started
### Prerequisites
- Rust 1.71.0 or later
- Cargo
### Run a local testnet
#### Build the app
```bash
cargo build
```
### Setup the testnet
Generate configuration and genesis for three nodes using the `testnet` command:
```bash
cargo run -- testnet --nodes 3 --home nodes
```
This will create the configuration for three nodes in the `nodes` folder. Feel free to inspect this folder and look at the generated files.
### Spawn the nodes
```bash
bash spawn.bash --nodes 3 --home nodes
```
If successful, the logs for each node can then be found at `nodes/X/logs/node.log`.
```bash
tail -f nodes/0/logs/node.log
```
Press `Ctrl-C` to stop all the nodes.
## Usage for Rollups
Rollups can submit data to Mikan via its API:
1. **Submit Data**: Rollup submits transaction data to Mikan nodes
2. **Receive Commitment**: Mikan returns a cryptographic commitment to the data
3. **Verify Availability**: Anyone can verify data availability by sampling
The FRI commitment can be included in the rollup's state transition proof, creating
a seamless integration between the rollup's validity proofs and data availability guarantees.
