Sees Co., Ltd. has completed the development of a "Hashchain," a next-generation product for its blockchain IoT business, and has begun marketing it.
The "Hashchain" is a chip based on Sees' proprietary "Hashchain," the third layer of blockchain technology, and enables secure wireless I/O control in factories and local areas.
Currently, in many factories, data is transmitted between sensors, actuators, etc. and control devices via wired communication in an exclusive environment where Internet connection to the outside world is prohibited for the purpose of maintaining confidentiality.
Wired communication involves complicated cables, and the diameter of a bundle of cables around the control unit, where the largest number of connections are made, can be as large as several tens of centimeters.
The more connections there are, the more physical space is occupied by cables and the more time is required for fault detection and replacement. However, the number of channels for wireless communication exceeds the allowable range due to data transmission/reception between multiple sensors and actuators and control devices, making wireless connection unfeasible in reality.
Furthermore, the risk of information leakage to the outside is extremely high in wireless data transmission, and together with the problem of the number of channels, this is a major issue.
To solve this problem, Sees Co., Ltd. has developed and patented a communication system that transmits data using only the transaction part of the blockchain.
This "Hashchain" is connected to a distributed network, so it requires only one channel for wireless communication. This system is so small that it can be connected directly to sensors and actuators.
