fix: weed out false outtx tracker submission #920

Open brewmaster012 opened 1 year ago

brewmaster012 commented 1 year ago

Currently there is no validation of observer submitted outbound tx hash. There are two problems with this lack of validation:

  1. When broadcast a signed tx, sometimes RPC returns successful but the tx is not successful.
  2. A potentially malicious observer could spam the network and perform DoS

Need: light-weight validation to weed out obvious false out tx tracker submission.
