Encryption algorithms in blockchain technology

In the digital age, intelligent devices produce data intensively. There is a need for protection in the transmission and storage of this data. Blockchain is a record of encrypted data transfers on the Internet. This new technology uses complex mathematical functions. As the blockchain grows, the solution of these operations becomes more difficult. Since it creates strong encryption on digital identity, it has started to be used in internet of objects, big data, artificial intelligence and robot technology. There is no need for a central authority in blockchain technology. Transactions are carried out directly between the buyer and the seller and in a safe manner. The history of all transactions is publicly available on the network. It provides the opportunity to use secure technologies in critical areas such as finance, health, education, insurance, industry, energy and military. Due to the opportunities it provides, different sectors adapt their business practices to the blockchain technology. In this study, encryption algorithms of blokchange encryption technology will be examined.
