We design and implement TwinsCoin, the first cryptocurrency based on a provably secure scalable public blockchain using both proof-of-work proof-of-stake mechanisms. Different from Bitcoin, our construction uses two types of resources, computing power coins (i.e., stake). The in system is more robust than that pure system; even if adversary controls majority mining power, we can still have chance to by relying honest stake. In contrast, Bitcoin will be insecure 50% power.
