"Blockchain technology is the base technology for virtual currency. Now recently it was used in all the field of engineering and science. Due to the nature of security and scalability of the technology. Distributed ledger technology is advanced technology expanded to the healthcare, public sector problems, political and financial sectors. In the advancement of Distributed ledger technology will replace the databases of information. Now a days industry also using blockchain technology, smart industries smart grid are some examples under blockchain. In recent years blockchain is one of the advanced topics for both academic and industry. This blockchain will give vast opportunities for the development of future generation computing. combain artificial intelligence with blockchain technology will improve the future generation computing in all aspects. The basic concept behind Intelligence is that a system that functions as an electronic butler that senses user features and their environment can develop by enriching the environment with technology, such as sensors and devices that are networked. Blockchain and security systems provide a new way for innovating a wide range of application scenarios due to their beneficial characteristics of tamper-proof, transparency, trustworthy, and privacy protection. It can also ensure security and reduce property losses by enabling anonymous and trustful transactions in trustless environments. The recent boom of blockchain systems provides new opportunities and challenges, such as the lack of unified system performance evaluation indicators, heterogeneous blockchain systems are difficult to interact with, K-V data storage structure leads to single data query functions and fraudulent smart contracts, and so on. Intelligent blockchain is expected to play as a game-changing role in future communications and networking, since it can be exploited to provide innovative solutions to lots of emerging research issues in the next-generation communications and networking"--
