Zeth

Zeth is a Reth-based sequencer node for the Polygon Type 1 zkEVM. It facilitates witness generation that can be used as input to the Polygon prover. The project supports both SQLite and PostgreSQL backends for witness persistence.

Features

• Reth-Based Sequencer Node: Operates as a sequencer node for the Type 1 zkEVM.
• Witness Generation: Supports witness generation for the Type 1 prover.
• Backend Support: Offers both SQLite and PostgreSQL backends for witness data persistence.
• Modified Reth: Leverages a modified fork of reth.
• Modified revm: Leverages a modified fork of revm.

Installation

To install Zeth, follow these steps:

1. Clone the Repository:

   git clone https://github.com/fractal-zkp/zeth.git
   cd zeth

2. Build the Project:

   Use Cargo to build the project in release mode:

   cargo build --release

Usage

Once the project is built, you can run a development node with the following command:

./target/release/zeth node --dev --dev.block-max-transactions 1

This command runs a development node with a maximum of one transaction per block.

Note: If you receive the following error - Error: Failed to open database connection: error returned from database: (code: 14) unable to open database file then you must create the default sqlite database file by running touch polygon-zero.db.

Submit transactions to the rpc hosted at http://127.0.0.1:8545 with chain id 1337 using one of the test accounts associated with the test seed:

test test test test test test test test test test test junk

Prove the blocks using zero-bin, see the README.
