LayerZero v2: DVN stacks in production

"Good evening. Tonight we cover layerzero v2 dvns. This is the kind of topic that sits right on the seam between research and production, and we're going to walk through the construction before looking at what it means for the chains that actually ship it."

"The short version is this: LayerZero v2 made the security model application-configurable. We'll spend the first half of the segment on the core mechanism, and the second half on what operators are actually deploying."

"Let's start with the basics. Instead of a fixed oracle and relayer pair, every application picks a set of Decentralized Verifier Networks and an executor. A message is considered committed only when a quorum of the chosen DVNs signs off on the block header the payload was emitted in. Keep that in mind as we go deeper."
