Quick Start

This guide will walk you through deploying the SP1 Blobstream contract and running the operator.

Deploying SP1 Blobstream

1. To deploy an SP1 Blobstream contract for a Tendermint chain do the following.

   Get the genesis parameters for the SP1Blobstream contract.

   cd script
   
   # Example with Celestia Mocha-4 Testnet.
   TENDERMINT_RPC_URL=https://rpc.lunaroasis.net/ cargo run --bin genesis --release
   

2. Add the genesis parameters to /contracts/.env mirroring contracts/.env.example.

   | Parameter | Description | |-----------|-------------| | GENESIS_HEIGHT | The block height of the genesis block for the Tendermint chain | | GENESIS_HEADER | The header of the genesis block for the Tendermint chain | | SP1_BLOBSTREAM_PROGRAM_VKEY | The verification key for the SP1 Blobstream program |

3. Deploy the SP1Blobstream contract with genesis parameters: GENESIS_HEIGHT, GENESIS_HEADER, and SP1_BLOBSTREAM_PROGRAM_VKEY.

   cd ../contracts
   
   forge install
   
   forge script script/Deploy.s.sol --rpc-url <RPC_URL> --private-key <PRIVATE_KEY> --etherscan-api-key <ETHERSCAN_API_KEY> --broadcast --verify
   

   If you see the following error, add --legacy to the command.

   Error: Failed to get EIP-1559 fees    
   

4. Your deployed contract address will be printed to the terminal.

   == Return ==
   0: address <SP1_BLOBSTREAM_ADDRESS>
   

   This will be used when you run the operator in step 5.

5. Export your SP1 Prover Network configuration

   # Export the PRIVATE_KEY you will use to relay proofs.
   export PRIVATE_KEY=<PRIVATE_KEY>
   
   # For the Succinct network, set the private key corresponding to the public key in the SP1 Prover Network.
   export NETWORK_PRIVATE_KEY=<NETWORK_PRIVATE_KEY>
   
   # If you're using a custom RPC URL, set it here.
   export NETWORK_RPC_URL=<NETWORK_RPC_URL>
   
   # If you're proving locally, set the SP1_PROVER to "cpu".
   export SP1_PROVER=cpu
   

6. Run the SP1 Blobstream operator to update the LC continuously.

   cd ../script
   
   TENDERMINT_RPC_URL=https://rpc.celestia-mocha.com/ CHAIN_ID=11155111 RPC_URL=https://ethereum-sepolia.publicnode.com/
   CONTRACT_ADDRESS=<SP1_BLOBSTREAM_ADDRESS> cargo run --bin operator --release
