+- Wormhole is a decentralized proof-of-authority system. All nodes - called guardians - have equal voting power.
+  
+  A 2/3+ majority is required for guardians to achieve consensus. 
+  
+  The guardian set will consist of Solana validators, reputable community members, ecosystem stake holders
+  and other parties whose incentives strongly align with Solana and Solana ecosystem projects like Serum.
+  
+    - We believe that this model is easier to implement and reason about and more likely to result in incentive alignment
+      with Solana ecosystem stakeholders than launching a separate PoS chain.
+     
+  - It is possible to add staking in the future.
+ 
+- Wormhole is leaderless. All nodes perform the same computation upon observing an event.
+
+- Wormhole acts as a decentralized cross-chain oracle, observing finalized transactions on one
+  chain and producing a joint signed statement of all guardians on another chain.
