Cross-chain interoperability has always been a tough nut to crack. Lagrange claims that it can shorten the challenge period with proof, allowing a transaction to happen without a relay.

It's like getting people from the north and south to share a meal; there needs to be a way to harmonize. Whether it works out or not depends on the adjustment.
