View ChartTezos (XTZ) is a self-amending blockchain and smart contract platform designed to evolve without hard forks. Its on-chain governance system was pioneering in allowing the protocol to self-amend. It is an open-source platform for assets and applications that can upgrade itself by amending its own set of rules.
Tezos is a self-amending blockchain that upgrades itself through an on-chain governance process, avoiding disruptive hard forks. Its native token, XTZ, is used for staking (called "baking"), paying transaction fees, and participating in governance. The platform uses a Liquid Proof-of-Stake (LPoS) consensus mechanism, which is energy-efficient and allows token holders to delegate their staking rights. Tezos supports smart contracts and decentralized applications (dApps), with a focus on formal verification for enhanced security. It has a strong focus on real-world asset (RWA) tokenization and has cultivated a vibrant ecosystem in digital art and NFTs.

Tezos was created by Arthur Breitman and his wife, Kathleen Breitman. Arthur Breitman worked as a quantitative analyst for Goldman Sachs and Morgan Stanley, and as a research engineer for Google X and Waymo. He authored the Tezos whitepaper under the pseudonym "L. M. Goodman" in 2014. The project was later developed by their company, Dynamic Ledger Solutions, Inc. (DLS). A landmark initial coin offering (ICO) in July 2017 raised the equivalent of $232 million (66,000 BTC and 361,000 ETH), the largest ever ICO at the time. However, post-ICO disputes between the Breitmans and the Tezos Foundation over control delayed the mainnet launch. Its testnet launched in June 2018 (initial release 7.0 on 30 June 2018), and the mainnet went live in September 2018. Today, governance and development are decentralized, led by the Tezos Foundation and a global community of developers, bakers (validators), and researchers.
Tezos operates on a unique Liquid Proof-of-Stake (LPoS) consensus model. Token holders can "bake" (stake) their XTZ to participate in block creation and validation, earning rewards. Those who don't want to run a node can delegate their staking rights to a "baker" without transferring custody of their coins, maintaining liquidity. The core innovation is its self-amending governance. Upgrades are proposed, tested on a testnet, and then voted on by XTZ stakeholders. Once approved, the upgrade is automatically deployed to the mainnet. This on-chain process allows the protocol to self-amend and upgrade itself without leading to a split (or fork) in the blockchain. Smart contracts on Tezos are written in Michelson, a language designed for formal verification—a mathematical method to prove code correctness and prevent bugs.
Tezos's primary uniqueness lies in its self-amending, on-chain governance. This creates a sustainable upgrade path, giving it long-term adaptability that many first-generation blockchains lack. Tezos' LPoS consensus mechanism enables any stakeholder to take part, directly or by delegation, in the consensus process, and to be rewarded for securing the network. The Tezos protocol was initially built with formal verification in mind, enabling builders to avoid bugs when developing smart contracts, making it particularly suited to applications that require a high degree of security and certainty. Furthermore, Tezos has cultivated a vibrant ecosystem in digital art and NFTs, with platforms like fxhash and Objkt.com leading in generative art, thanks to its low fees and energy-efficient design.
The XTZ token has several core utilities within the Tezos ecosystem: Staking (Baking) — securing the network and earning rewards. Governance — voting on protocol upgrades and amendments. Transaction Fees — paying for computations and transactions on the network. dApp Interaction — used as the primary currency within Tezos-based decentralized applications. NFTs and Digital Art — a leading blockchain for minting and trading NFTs, particularly generative art.
The Tezos ecosystem is rapidly expanding beyond its core technology. Tezos has a strong focus on real-world asset (RWA) tokenization, and CoinMarketCap navigation includes Real-World Assets. The NFT and digital art scene remains exceptionally strong, fostering a unique creative community. To address scalability, the ecosystem is embracing Layer-2 solutions like Etherlink, an EVM-compatible rollup that brings Ethereum developers and dApps to Tezos. Protocol upgrades have introduced features such as the Data Availability Layer (DAL); the Ushuaia upgrade boosted DAL bandwidth to 10 MB/s, a 15x increase. Development is driven by multiple independent teams, including the Tezos Foundation, Tezos Commons, Nomadic Labs, Trilitech, and TZ Apac.
Tezos does not use mining. It secures its network through staking, known as "baking." Historically, becoming a baker required staking a roll of 8,000 XTZ; later protocol upgrades (e.g., Seoul, September 2025) introduced a simplified staking mechanism with one-click unstaking. This process involves baking (creating) new blocks and endorsing (validating) blocks created by others. For most users, the practical way to earn staking rewards is through delegation. You can delegate your XTZ holdings to an existing baker from your wallet without locking or sending your coins. The baker does the technical work, and you receive a portion of the rewards, typically after a service fee. This system is permissionless and energy-efficient.
Securing your XTZ involves using reputable tools and following best practices: Use Official Wallets — store XTZ in official, non-custodial wallets like Temple Wallet (browser extension) or Kukai Wallet (web-based). For mobile, consider AirGap. Hardware Wallets — for large holdings, use a hardware wallet like Ledger or Trezor. These keep your private keys offline and are compatible with Tezos for both storage and delegation. Secure Delegation — when delegating to a baker, choose a reliable one with a good track record and uptime. You only need to delegate from your wallet; never send your XTZ to a baker's address. Guard Your Keys — never share your seed phrase or private keys. Be wary of phishing sites pretending to be Tezos wallets or dApps.
XTZ is listed on many major exchanges and can be bought with fiat or stablecoins; compare fees, custody model, and regulatory status before choosing a venue.
XTZ is a volatile crypto asset, and its price can fluctuate significantly. Regulatory treatment of crypto assets varies by jurisdiction and may change. The Tezos protocol relies on ongoing development and network participation, and technical issues or governance disputes could affect its operation.
