Sunrise Data

This software "sunrise-data" is a program to publish and retrieve the BLOB data from off chain storage like IPFS, Arweave and so on.

Run sunrise chain node

Run Local IPFS Node

sunrise-data uses IPFS protocol to upload metadata and shard to IPFS.

1. Download and extract ipfs node binary

You can download official prebuilt binaries from IPFS kubo and Extract kubo_v0.31.0_linux-amd64.tar.gz after download.

wget https://dist.ipfs.tech/kubo/v0.29.0/kubo_v0.29.0_darwin-amd64.tar.gz

2. Install IPFS

macOS

mv ./kubo/ipfs /usr/local/bin/

Linux

wget https://dist.ipfs.tech/kubo/v0.31.0/kubo_v0.31.0_linux-amd64.tar.gz
tar -xvzf kubo_v0.31.0_linux-amd64.tar.gz
cd kubo
sudo ./install.sh

To check ipfs has been installed.

ipfs version
　ipfs version 0.31.0

3. Initialize IPFS

ipfs init --profile=lowpower

4. Run IPFS as daemon

ipfs daemon

5. Get IPFS node id

ipfs id

6. Add a remote IPFS node to the peer list

ipfs bootstrap add /ip4/13.114.102.20/tcp/4001/p2p/12D3KooWSBJ1warTMHy7bdaViev6udyWU8XBnz9QCYS8TSX9qadt

You can visit http://localhost:8080/ipfs to check runing IPFS RPC.

Store project

This project need to store in directory stored "sunrise" codebase

ls
　sunrise
  sunrise-data

Setup Config

Copy config.default.toml to config.toml and edit

Common

1. ipfs_api_url: To connect to a local IPFS daemon, leave this field empty
2. home_path: Your sunrised path. Usually ends with .sunrise.
3. keyring_backend: sunrised's keyring
4. sunrised_rpc: sunrised's RPC URL. To connect to a local chain, use http://localhost:26657

Only L2 Publisher

1. publisher_account: Account to send MetadataUrl of L2 data to Sunrise chain, $RISE balance required.
2. publish_fees: If not enough, increase this.

Only Validator

1. proof_deputy_account: Account on behalf of the proof, which must be registered with MsgRegisterProofDeputy tx.
2. validator_address: Your validator address. Prefixed sunrisevaloper.
3. proof_fees: If not enough, increase this.

Testing Example for API Endpoint

1. Publsh

POST http://localhost:8000/publish
Request
{
    "blob": "MTIzNDU2Nzg5MDEyMzQ1Njc4OTA=",   // "12345678901234567890"
    "data_shard_count": 5,
    "parity_shard_count": 5,
    "protocol": "ipfs" // or "arweave"
}

Response
{
    metadata_uri: "ipfs://QmPXFt19HTkGjoZcbavLEgYYsuPm2xJR7hkhQxtRgPURMU"
}

2. Shard Hashes API

GET http://localhost:8000/shard-hashes?metadata_uri=ipfs://QmPdJ4GtFRvpkbsn47d1HbEioSYtSvgAYDkq5KsL5xUb1C&indices=1,2,3

{
    "shard_size":7,
    "shard_uris":[
