Tezos (XTZ) is a decentralized blockchain platform that allows for the creation and execution of smart contracts. It is designed to be self-amending, meaning that the protocol can be upgraded without the need for hard forks.

As for the advantages of Tezos, here are 15 key benefits:

1. Self-amendment: Tezos has a built-in mechanism for protocol upgrades, allowing it to evolve and adapt over time.

2. Security: Tezos utilizes formal verification, a technique that mathematically proves the correctness of smart contracts, enhancing security.

3. Governance: Tezos has a unique on-chain governance system that allows token holders to participate in decision-making and protocol upgrades.

4. Flexibility: Tezos supports multiple programming languages, making it more accessible for developers.

5. Scalability: Tezos uses a liquid proof-of-stake consensus algorithm, which enables high transaction throughput and scalability.

6. Energy efficiency: Compared to proof-of-work blockchains like Bitcoin, Tezos consumes significantly less energy.

7. Privacy: Tezos offers privacy features, allowing users to keep their transactions and smart contracts private if desired.

8. Interoperability: Tezos can interact with other blockchains through cross-chain communication protocols, enabling interoperability.

9. Formal governance process: Tezos has a formal process for proposing and implementing protocol upgrades, ensuring transparency and accountability.

10. Community-driven: Tezos has a vibrant and active community of developers, validators, and token holders who contribute to its growth.

11. Decentralization: Tezos aims to be a decentralized network, with a large number of validators spread across the globe.

12. Low fees: Tezos has relatively low transaction fees compared to other blockchain platforms.

13. Smart contract functionality: Tezos supports the creation and execution of complex smart contracts, enabling a wide range of applications.

14. Long-term sustainability: Tezos has a treasury system that funds ongoing development and maintenance of the protocol.

15. Ecosystem growth: Tezos has a growing ecosystem of dApps, projects, and partnerships, indicating its potential for future expansion.
