Method for the validation of transaction data of blockchains based on special relativity

This invention proposes a new way to validate transactions on blockchains, called Space PoET, that uses the fundamental law of physics that nothing can travel faster than light. Instead of relying on energy-intensive computing or locking up coins, it forces transaction validation messages to travel through a series of distinct network points, measuring the time it takes. This ensures a minimum elapsed time and makes it very hard to cheat the system, especially when used with satellite networks in space.
