Rust implementation of Celestia's data availability node able to run natively and in the browser-based environments.

Supported features:

• Synchronize and verify ExtendedHeaders from genesis to the network head
• Header exchange (header-ex) client and server
• Listening for, verifying and redistributing extended headers on gossip protocol (header-sub)
• Persistent store for Headers
• Integration tests with Go implementation
• Data Availability Sampling
• Creating, distributing, and listening for Fraud proofs

Follow this guide to authorize yourself in github's container registry.

Start a celestia network with single validator and bridge

docker-compose -f ci/docker-compose.yml up --build --force-recreate -d

When deleting, remember to also delete subvolumes:

docker-compose -f ci/docker-compose.yml down -v

To get the JWT token for the account with coins (coins will be transferred in block 2):

export CELESTIA_NODE_AUTH_TOKEN=$(docker-compose -f ci/docker-compose.yml exec bridge celestia bridge auth admin --p2p.network private)

Accessing json RPC api with Go celestia cli:

celestia rpc blob Submit 0x0c204d39600fddd3 '"Hello world"' --print-request

Extracting blocks for test cases:

celestia rpc header GetByHeight 27 | jq .result

Make sure you have the celestia network running inside docker-compose from the section above.

Generate authentication tokens for the tests

./tools/gen_auth_tokens.sh

Run tests

cargo test
