Internet of Things should be regarded as one of the hottest concepts in the post-Internet era. In fact, as early as 2000, Internet of Things technology was applied in the industrial field. Different from the centralized cloud computing architecture adopted nowadays, due to security needs, the Industrial Internet of Things Most use small, fragmented, closed architecture. Ten years later, the Internet of Things (IoT) has inherited the mode of Internet-centric cloud platform. The centralized cloud further eliminates the fragmentation and improves the convenience of large coordination. From a cost and security point of view, the centralized cloud architecture Not the best form of things. The emergence of the blockchain, like a dark horse, provides a perfect P2P architecture for the Internet of Things. A team called Q-Digital Technology at the Shanghai IoT Center is pushing the Internet of Things into a decentralized device-autonomous era through blockchain. Internet of Things + blockchain technology into the shared economy In today's technology is so advanced, why the Internet of Things architecture is not directly from the small-scale LAN directly into a more suitable P2P architecture? Instead, a structural evolution has taken place and the evolution from a closed, fragmented system to a more centralized, secure, less-than-optimal system appears to have taken a detour. Q Si digital technology founder Bi Siqing that the technical reasons are not the main reason, but because at present we have no way to establish the trust of strangers, can only rely on centralized trust and supervision. Another factor is driven by profit. ICT giants, who hold the dominant position in the industry, are pushing aggressively for a centralized cloud computing model that takes advantage of looted data, generating new business models and grabbing huge profits. Therefore, the most enthusiastic giants is to build the platform. In the past, there was not a tool for large-scale P2P assistance. The main reason was not the technical ability. However, the return of P2P to capital was too small and capital did not want to flow in this direction. The characteristics of the blockchain itself, natural to solve the above-mentioned P2P and stranger trust issues. Not only that, the blockchain stems from the financial sector, focusing on the exchange of value. Its thinking goes beyond some of the Internet of Things innovations, such as fog computing and edge computing, which often target physical efficiency optimization. Therefore, as a field of IoT veterans Bi Siqing, after contact with the blockchain, did not hesitate to open the IoT + blockchain exploration process. At present, Q Special Digital Technology launched the IoT smart lock system running on the blockchain. As a lock, whether it is smart or not smart, we must first solve the security problem. Bi Siqing pointed out that the blockchain itself has the characteristics of a super-secure transaction mechanism for digital assets. By introducing these features into physical electronic locks, all the advantages of the blockchain are transferred to the realm of asset-user transactions. The first is security, including the blockchain's own security mechanism, cryptography, consensus mechanism, and decentralized features. There is no risk that the central database will be attacked. Secondly, the cost, the application framework of the blockchain itself is simple, Smart contracts minimize operating costs and monitoring costs; stranger trust mechanisms remove the high cost of intermediation. Smart Lock is currently an entry and just-needed product in the smart home and security space. In the B-side market, real estate developers, hotels, rental apartments, etc. are the key customers smart lock. The hotel, apartment and other scenarios under the smart lock has been a certain degree of application. In addition, the smart lock home market also has a lot of room for growth: China has a population of 1.4 billion and nearly 400 million households, it may become the world's largest smart lock market. In fact, Q special technology aimed not only smart lock such a single product, but more emphasis on the block chain to enhance the shared economy. Currently mainly for housing leasing, car rental, rental car, etc., based on the blockchain-based physical asset sharing solutions. The current Internet sharing giants, only aggregating idle resources, charge a high commission intermediary, not a real sharing. Bi Siqing told 36 krypton,? Q special digital technology in the first phase we make a most secure smart lock, through the combination of intelligence and peace of mind, make us the most secure and efficient use of physical assets exchange. In the 2.0 phase, we added tokens on the basis of 1.0, securitization of physical assets, free circulation and trading to achieve a truly shared economy. At 3.0, we add artificial intelligence based on 2.0 to make the physical assets become smart assets, realize the maximum value independently, promote efficient social production and avoid the waste of social resources. In the team, CEO Bi Siqing, has 18 years of experience in the field of automation and networking, and currently serves as Shanghai CTO & VP of Smart Technologies.
