Blockchain technology includes the domains of cryptography, computer networks, and security. Since 2008, it has progressed through three generations and many different use cases. Each generation builds on the previous one in an original way, but the basic idea of a decentralized system that allows consensus without trust between individual actors remains the same. The aim of this thesis is to analyze the Tezos blockchain, evaluate Tezos node and smart contracts. The publication describes the state of blockchain technology, the theory of the Tezos system, its protocols, and the modern consensus algorithm that makes it a third-generation blockchain technology. A stand-alone server was set up to host two virtual machines for two Tezos nodes on the mainnet and testnet. The origination and use of Tezos smart contracts were tested with FA1.2 and FA2 standards. The results of this publication could be valuable to anyone interested in the development on the Tezos blockchain.
