Summary: Using .NET to create web applications and the Volta compiler to automagically generate the required JavaScript code allows for a uniform development platform.<p>The problem: the client code that was once trusted because it lives on a server not resides on untrusted clients. Ripley sits between the server and the client, and runs a replica of the code running on the client. Any input on the client is sent to the replica to be run as well, if the outputs do not agree the code fails.<p>End result: Faster response time on the client(due to the use of client-side code) but integrity of computation.
