Last week, we observed an increase in panic logs, as shown below:

ERROR tokio-runtime-worker runtime: panicked at 'Bad input data provided to validate_transaction: Codec error', /build/runtime/kusama/src/lib.rs:1661:1

These logs are present on both Kusama nodes and Kusama parachain nodes.

Just means that someone is sending invalid transactions to the node. Maybe ban the IP after a few tries?
