Connext vs. PoS/MPC Systems
External validators (or oracles) are responsible for moving data between chains in PoS/MPC interoperability frameworks.
PoS/MPC interoperability systems are externally verified systems.
Externally verified systems are generalized interoperability frameworks that are easy to build. However, the underlying security model of such systems is in any case weaker than that of the bridge’s underlying chains.
Connext inherits its high level of security from the underlying base chains but does not offer the same level of generality as a PoS/MPC system.
The bridging solution provided by Connext is the optimal solution whenever generality is not needed and when a high amount of value needs to be transferred across chains.
