Dear Colleagues,

Blockchain technology is used to strengthen the security of wireless sensing data in the network architecture of the Internet of Things (IoT). Blockchain technology can make data transfer in the IoT architecture more secure. The blockchain has several most important features. The first is its core tenet—decentralization. In order to emphasize the shared nature of the blockchain, users cannot rely on additional management agencies and hardware facilities to make it A central mechanism is required, so the data on each blockchain are stored on different clouds, accounting and storage are decentralized, and each node needs to self-verify, transmit and manage, this decentralization is the block The most prominent and core essential feature of the chain. Blockchain technology can be said to be the most disruptive innovative technology since the Internet era. It relies on complex cryptography to encrypt data, and then through ingenious mathematical decentralized algorithms, the most worrying security and trust issues on the Internet can be solved. It allows users to reach a consensus without the need for third-party intervention, and solves the problems of trust and data value on the Internet at a very low cost.

Another major feature of the blockchain is its "non-tampering". Once written, each piece of data in the blockchain cannot be changed. As long as the data is verified, it will be permanently written into the block. The technology is through the Hash algorithm, through a one-to-one function to ensure that the data will not be easily tampered with, this function can be easily verified but very difficult to crack. Even the blockchain hash value cannot be easily deduced from the original value, and the data cannot be tampered with. The value obtained from each block will also be put into the next block, so that the data between the blockchains are also correctly guaranteed.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Electronics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
