Sunrise DA

Golang implementation of Sunrise's data availability node types (light | full | bridge).

The sunrise-da types described above comprise the sunrise data availability (DA) network.

The DA network wraps the sunrise-core consensus network by listening for blocks from the consensus network and making them digestible for data availability sampling (DAS).

cd sunrise-da
make build
sudo make install

API docs

The sunrise-da public API is documented here.

Node types

• Bridge nodes - relay blocks from the sunrise consensus network to the sunrise data availability (DA) network
• Full nodes - fully reconstruct and store blocks by sampling the DA network for shares
• Light nodes - verify the availability of block data by sampling the DA network for shares

More information can be found here.

Run a node

<node_type> can be: bridge, full or light.

sunrise-da <node_type> init

sunrise-da <node_type> start

Network

• Mainnet - the main network of Sunrise. Use tokens with real value
• Testnet - This network is used to test operations on the mainnet. Normally, the same environment as the mainnet is provided, but tokens have no value
• Private - a network for testing new features. It may contain critical bugs. Do NOT normally use

Run a bridge node

Bridge nodes connect the data availability layer and the consensus layer.

sunrise-da bridge init --core.ip <URI> --p2p.network <NETWORK>

The --core.ip gRPC port defaults to 9090. Normally, set up a RPC node running sunrise-app.

sunrise-da bridge start --core.ip <URI> --p2p.network <NETWORK>

Run a full node

Full storage nodes are Sunrise nodes that store all the data. Full storage nodes send block shares, headers, and fraud proofs to light nodes.

sunrise-da full init --p2p.network <NETWORK>
sunrise-da full start --core.ip <URI> --p2p.network <NETWORK>

Start a full node using RPC. The bridge and full nodes refer to bootstrap.go.

Run a light node

Light nodes ensure data availability. This is the most common way to interact with Sunrise networks. It does NOT require large storage or high-speed connections.

sunrise-da light init --p2p.network <NAME>
sunrise-da light start --core.ip <URI> --p2p.network <NAME>
