There are two bugs:

  1. We should not allow users to specify the crossChainSync address, it should always be the "taiko" address on the curernt chain.
  2. We should check that each hop relay -- the middleman contract that sends stateRoot as a signal to its local signal service. Previously this address is not verified correctly using the AuthorizableContract contract. Now we removed AuthorizableContract and introduce a HopRelayRegistry to verify hop relays explicitly. Note that if the signal service disabled multi-hop bridging, the HopRelayRegistry is not needed.

Approved because I think this correctly links the difference chains, but still with low certainty.

Lets disable multi-hop for now in the code.
