# Chaintip Attestation

Validators first send the Chaintip attestations received from fork scanner via websocket connection to the BTCOracle. 

```protobuf
message MsgSeenBtcChainTip {
  uint64 height = 1;
  string hash = 2;
  string btcOracleAddress = 3;
```

This message loops till there's 2/3rd attestation available.
