Sunrise Alt DA

Sunrise Alt DA connects the L2 blockchain to Sunrise's Data Availability Layer. Currently, L2 chains created in the OP Stack are supported.

See OP Stack for L2 chain side configuration.

Sunrise Consensus Node

Requires a networked Sunrise node to operate. Networks running Sunrise v0.3.0 or higher support Data Availability Layer.

Follow the Node Guide on how to create a consensus node.

How to set up Alt DA

sunrise-data

1. Clone sunrise-data repo

   cd ~
   git clone https://github.com/sunriselayer/sunrise-data.git
   cd sunrise-data
   make install

2. Create and edit config.toml

   cp config.default.toml config.toml
   nano config.toml

3. To connect to a local IPFS daemon, leave the ipfs_api_url field empty

   Chage home_path to your .sunrise directory and publisher_account to your sunrised key's name

   [api]
   port = 8000
   ipfs_api_url = ""
   ipfs_addrinfo = ""
   submit_challenge = true
   submit_proof = true
   
   [chain]
   addr_prefix="sunrise"
   keyring_backend="test"
   home_path="/home/ubuntu/.sunrise"
   publisher_account="validator"
   fees="10000uvrise"
   cometbft_rpc="http://localhost:26657"
   vote_extension_period=2

   tar -xvzf kubo_v0.31.0_linux-amd64.tar.gz
   cd kubo
   sudo ./install.sh
   ipfs init --profile=lowpower
   ipfs daemon

2. Check the IPFS node ID and optionally share and add a remote peer
