Crosschain Atomic Swaps

Ethan and Nicolas describe atomic cross-chain swaps - a protocol where two parties can exchange coins as a single operation. The exchange does not require any trusted third party and neither of the parties involved can cheat each other. They describe how this can be used on a single blockchain as a privacy protocol or “cross-chain” as a trading protocol. Nicolas demonstrates an atomic cross-chain trade of Bitcoins for Litecoins.
