Lightning gets an honorable mention for sure, but it falls to all the same criticisms levied against Drivechains. Except lightning has a few practical limitations that will prevent it from ever becoming 'money'. First of which: Bitcoin literally cannot process enough transactions to onboard the human race into the lightning network.

Lightning is awesome for what it is, but the only way it can reach global scale is with trusted centralized 'platforms' no different than fiat banks. You see it already with WalletOfSatoshi. Those of us looking to build freedom money cannot settle for a new system of trusted banks. We're trying to cut banks out of the picture and build money for the people.
