Description

Certain chains require a number of confirmations, for a transaction to be considered final. We need to spec out a general approach to this, that is easy on compute, and doesn't introduce to much complexity for rangers/relayers.

Example: Why this is important:

• Eth Escrow transfer is executed as side_effect
• Ranger instantly submits the header its included in
• Inclusion proof is submitted and circuit emit Release event
• Eth finds a longer chain, our transfer is now reverted -> divergent state between circuit and target
