• Time attacks: setting your timestamp forward so your change is the winner "for the next two years."
• Vector attacks: setting your state counter forward so your change is the winner "for the next ten million cycles."
• Vector clock: a clock which is incremented every time data is sent or received.
• Deferred updates: hold future things in volatile memory until the time comes when they would have been valid

Hypothetical Amnesia Machine

• machineState: The current time of the local machine.
• incomingState: The time of the update from the remote machine.
• currentState: The time of the last update on the local machine.
• incomingValue: The data coming from the remote machine.
• currentValue: The data stored in the local machine.
• GunDB is based around these parameters.
• Updates prior to the oldest state are journaled (optional)
• Updates between oldest and current state are merged
• Updates beyond the current state are held in memory until appropriate
• Information which is "too far" in the future is held in volatile memory until its time comes.
