I don't know how long, when everyone talks about the blockchain, they are all discussed as an independent technology, but everyone does not know that the greatest charm of the blockchain lies in the credible transformation of the existing Internet. At the same time, it can be used in combination with other technologies to better realize the landing of related applications. At the 10th China International Internet of Things Expo Summer Exhibition in 2018, the exhibition covered RFID, sensors, smart cards, barcodes, communications, 4G/5G, LoRa, NB-IoT, cloud computing, mobile payment, tag anti-counterfeiting, smart home, The entire IoT industry chain and related products, such as smart transportation, smart cities, and environmental monitoring, have basically completed the prototype of the IoT industry chain. In the face of the upcoming 5G explosion and blockchain technology, what sparks are expected?
In addition to the simple realization of online and networked information recording and feedback, and the use of APP for operation, the Internet of Things system also requires Security protection to prevent hackers from intruding and sabotaging. In addition to the corresponding networking of items, the blockchain technology can also help realize the safe storage of information, prevent tampering and attack, make the Internet of Things network more secure and reliable, and reduce the cost of networking. Of course, this is just a hypothetical situation under ideal conditions. However, with the outbreak of 5G technology, the combination of the Internet of Things and blockchain is the future development trend.
At present, the combination of artificial intelligence and Internet of Things technology is developing rapidly, such as Baidu's Baidu Tiangong and Apollo unmanned driving projects; Huawei's Huawei cloud services and NB-IoT solutions; Alibaba's Alibaba Cloud, Link IoT platform, and urban brain; Tencent QQ Internet of Things, cloud big data storage; ZTE’s AnyLink Internet of Things platform; JD’s Weilian; Keda Xunfei’s Lingxi 3.0, etc., belong to the Internet of Things projects that have already landed. However, the current Internet of Things solutions are centralized management. Once the signal transmission channel of the connected objects is destroyed or delayed due to external reasons, there will be use risks. Blockchain technology can allow objects to establish multiple networked nodes, simultaneously transmit multi-channel signals, establish related connections with the surrounding environment, and achieve real-time stable multipoint transmission of signals. It can be seen that the maturity of blockchain technology can make the Internet of Things technology more Mature, but this has not yet been confirmed.
In the centralized network of the Internet of Things, the encryption method of many information is relatively simple, and it is easy to be cracked during transmission. Personal privacy is easy to be accessed and leaked. The asymmetric encryption technology used by the blockchain can achieve machine trust without accessing its own specific data. That is, individuals can encrypt and authorize information, and when information collection is needed, they can release information management authority and authorize information access. After the information is used, the encryption private key of the information can be modified at any time to disconnect the access in time. Of course, in the blockchain network, machine trust can be realized, information loss and tampering can be prevented, and the security during access is stronger.
What is worth looking forward to is that many different types of blockchain networks will be born in the future. And the network between blockchains can be interconnected. People's life under the combination of the Internet of Things, artificial intelligence, blockchain and other technologies will be more convenient, faster and safer, and they may become part of a blockchain network and gain shared benefits from the growth of the network. So, if this day comes, are you ready again?
