“…Common solutions are longer wait times or using multiple resources that ignore possible attacks or problems in real use, usually with various exceptions and a large number of transactions. Using epoch and several synchronized block intervals, deterministic finality can be achieved [11] with more flexibility than absolute finality. However, it requires long (100-block) epoch times and utilizes a distributed hash table to assume perfect (under some bound) network connection [12].…”

Since FinTech was stimulated by the invention of blockchain, without the full realization of blockchain technologies in the following years, FinTech has not been fully realized. We discuss some myths and reasons for why blockchain technologies were not fully realized. The lack of distributed synchronization might be the most difficult challenge such that the trust provided by blockchain is not good enough for public use. We propose a mathematical solution with a new consensus mechanism based on general Proof-of-Work mining, called Proof-of-PowerTimestamp, to reach distributed synchronization and reduce power consumption to less than one billionth of Bitcoin. We also discuss related issues toward blockchain realization once the distributed synchronization and energy consumption problems are solved. Since the issues are mostly interdisciplinary or multidisciplinary, researchers are invited to cooperate to help blockchain realization as soon as possible.

“…It usually results in various exceptions and even more transactions or synchronization load to handle. Using the epoch, several synchronized block intervals and deterministic finality can be achieved with more flexibility than absolute finality [ 19 ]. However, it needs a long (100-block) epoch and uses a distributed hash table to assume the perfect (under some bound) network connection [ 20 ].…”

“…We focus on the finality of system states. Absolute, stochastic, probabilistic, and deterministic finalities have been discussed with slightly different meanings [ 8 , 19 , 25 ]. If resources are limited, system states are bounded and everything is deterministic eventually.…”

Internet of Things (IoT) is used to describe devices with sensors that connect and exchange data with other devices or systems on the Internet or other communication networks. Actually, the data not only represent the concrete things connected but also describe the abstract matters related. Therefore, it is expected to support trust on IoT since blockchain was invented so that trusted IoT could be possible or, recently, even metaverse could be imaginable. However, IoT systems are usually composed of a lot of device nodes with limited computing power. The built-in unsolved performance and energy-consumption problems in blockchain become more critical in IoT. The other problems such as finality, privacy, or scalability introduce even more complexity so that trusted IoT is still far from realization, let alone the metaverse. With general Proof of Work (GPoW), the energy consumption of Bitcoin can be reduced to less than 1 billionth and proof of PowerTimestamp (PoPT) can be constructed so that a global even ordering can be reached to conduct synchronization on distributed systems in real-time. Therefore, trusted IoT is possible. We reintroduce GPoW with more mathematic proofs so that PoPT can be optimal and describe how PoPT can be realized with simulation results, mining examples and synchronization scenario toward trusted IoT.
