Wormhole guardians and the VAA rebuild
The 2022 exploit, the guardian set model, and the long engineering road back. We look at what the VAA verification pipeline looks like post-rebuild.
FROM THE BROADCAST
"Good evening. Tonight we cover wormhole guardians and vaa verification. 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: Wormhole is a message passing network secured by a permissioned guardian set. 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. Guardians observe emitted messages on source chains and co-sign a Verified Action Approval. A VAA is just a signed payload: destination chains verify the threshold signature and execute the message. Keep that in mind as we go deeper."
