Light-Client

Implementation of the Light Client Verification and Fork Detection protocols.

Documentation

See documentation on crates.io.

Example

The code below demonstrates the main use case for the Tendermint Light Client: syncing to the latest block, verifying it, and performing fork detection.

Please refer to the light_client example for fully working code.

```rust let primaryinstance: Instance = makeinstance(primary, primaryaddr, primarypath); let witnessinstance: Instance = makeinstance(witness, witnessaddr, witnesspath);

let mut peeraddr = HashMap::new(); peeraddr.insert(primary, primaryaddr); peeraddr.insert(witness, witness_addr);

let peerlist = PeerList::builder() .primary(primary, primaryinstance) .witness(witness, witness_instance) .build();

let mut supervisor = Supervisor::new( peerlist, ProdForkDetector::default(), ProdEvidenceReporter::new(peeraddr), );

let mut handle = supervisor.handle();

// Spawn the supervisor in its own thread. std::thread::spawn(|| supervisor.run());

loop { // Synchronously query the supervisor via a handle let block = handle.verifytohighest();

match block {
    Ok(light_block) => {
        println!("[info] synced to block {}", light_block.height());
    }
    Err(e) => {
        println!("[error] sync failed: {}", e);
    }
});

std::thread::sleep(Duration::from_millis(800));

} ```
