Build and deploy locally

cargo build
cargo run

Open localhost:8000 or localhost:8000/playground

Dockerize

This is specific to deploying on render.com. docker build is resource intensive. Increase memory and swap space on docker UI to the max and wait.

export DOCKER_DEFAULT_PLATFORM=linux/amd64
docker build -t <docker_id>/da:v1.0.0 .
docker push <docker_id>/da:v1.0.0 # may need to do docker login first

NEAR

1. Create keypair using near cli
2. Build and deploy Blob contract using the created account: https://docs.near.org/data-availability/integrations. NEAR_CONTRACT has to be set to account_id (the user provided string, similar to any user handle).
3. Deploying doesn't call new() function. Run near contract call-function as-transaction daaggregator.testnet new text-args '' prepaid-gas '100.0 Tgas' attached-deposit '0 NEAR' sign-as daaggregator.testnet network-config testnet sign-with-keychain send

Celestia

• Install celestia-node (instead of celestia version, run ./build/celestia version). https://docs.celestia.org/nodes/light-node#start-the-light-node
• celestia light init --p2p.network mocha. Save its output somewhere.

Get rpc endpoint here: https://docs.celestia.org/nodes/mocha-testnet#rpc-endpoints

• We used github.com/eigenco/lumina for rust client.
  • Refer to https://github.com/Ferret-san/celestiabox for a working example of golang code to submit blobs to a light client. Although in go, this helps in seeing how to call a light client.
