Tezos is an open-source, decentralized blockchain network designed to support and execute smart contracts and decentralized applications. Conceived in 2014 by Arthur and Kathleen Breitman, the project launched its mainnet in 2018. It is distinguished from many other blockchain platforms by its unique approach to evolution and governance. A central feature of Tezos is its self-amending protocol. This allows the network to upgrade itself through a formal, on-chain governance process without the need for a hard fork. In many traditional blockchains, major upgrades require the community to split into two separate paths, which can lead to fragmentation. Tezos avoids this by allowing stakeholders to vote on proposed protocol amendments. Once an upgrade is approved by a supermajority, it is automatically implemented across the network, ensuring long-term stability and continuous technical improvement. The network operates using a consensus mechanism known as Liquid Proof-of-Stake. In this system, participants who secure the network and validate transactions are referred to as bakers. Unlike some other models that limit the number of validators, Tezos allows any participant with a sufficient stake to become a baker. Those who do not wish to operate their own hardware can delegate their assets to a baker while retaining ownership. This mechanism is designed to be energy-efficient and inclusive. Tezos places a strong emphasis on security and code correctness through a process called formal verification. This mathematical approach helps developers prove that their smart contracts will behave exactly as intended, reducing the risk of bugs or vulnerabilities. Because of this focus on high-grade security, the platform is frequently used for high-value applications, including financial services, supply chain management, and government projects. The ecosystem around Tezos supports a wide range of use cases such as digital art, decentralized finance, and gaming. It has been adopted for real-world projects, such as digitizing vehicle titles and verifying judicial records. The native token, XTZ, serves as the utility engine for the network, used to pay for transaction fees, participate in the governance voting process, and secure the blockchain through the baking and delegation system. By combining an adaptable governance model with secure smart contract capabilities, Tezos aims to provide a sustainable foundation for decentralized technology.
