Tezos (XTZ) is a self-amending blockchain platform designed to support decentralized applications (dApps) and smart contracts. Unlike many other blockchain networks that require contentious hard forks to implement upgrades, Tezos features an innovative on-chain governance model that enables seamless, community-driven evolution. This unique approach positions Tezos as a forward-thinking alternative in the competitive landscape of smart contract platforms.
With its native cryptocurrency, Tez (XTZ), Tezos facilitates transactions, staking, and participation in network governance. Since its mainnet launch in 2018, Tezos has cultivated a vibrant global ecosystem spanning decentralized finance (DeFi), non-fungible tokens (NFTs), gaming, and enterprise use cases.
The Origins and Vision of Tezos
Conceived in 2014 by Arthur Breitman and Kathleen Breitman, Tezos was envisioned as a self-governing, long-lived blockchain capable of adapting to technological and regulatory changes without fracturing the network. The project raised $232 million during its July 2017 token sale, making it one of the largest initial coin offerings (ICOs) in history at the time.
The Tezos Foundation, a non-profit based in Switzerland, oversees the development and promotion of the blockchain. This institutional backing has helped foster trust and sustained growth, even through bear markets.

How Tezos Works: Proof-of-Stake and On-Chain Governance
Tezos operates on a Proof-of-Stake (PoS) consensus mechanism, specifically a variant known as Liquid Proof-of-Stake (LPoS)—a model unique to Tezos.
In LPoS, users who hold at least 6,000 XTZ can become bakers, responsible for creating new blocks and endorsing transactions. Users with fewer XTZ or those who prefer not to run infrastructure can delegate their stake to bakers and still earn staking rewards—without giving up custody of their tokens.
This delegation model promotes decentralization while lowering the barrier to participation in network security.
On-Chain Governance: Upgrading Without Hard Forks
One of Tezos’ most distinguishing features is its on-chain governance system. Instead of relying on off-chain debates or developer-led decisions, Tezos allows token holders to vote directly on proposed protocol upgrades.
The upgrade process follows five key phases:
- Proposal Phase: Bakers submit code-level upgrade suggestions.
- Exploration Vote: The community votes to shortlist proposals.
- Testing Phase: Selected proposals are tested on a temporary testnet.
- Promotion Vote: Another round of voting determines if the proposal moves forward.
- Adoption Phase: Approved upgrades are automatically implemented on the mainnet.
This structured process ensures that changes are thoroughly vetted and widely supported—avoiding the network splits seen in other blockchains like Bitcoin (e.g., Bitcoin Cash).
Real-World Upgrades: Case Studies in Self-Amendment
Tezos has successfully executed multiple major upgrades through its governance model, demonstrating its ability to evolve efficiently.
Ithaca 2 Upgrade (2022)
In April 2022, Tezos replaced its consensus algorithm with Tenderbake, a deterministic finality gadget inspired by Tendermint (used by Cosmos). This change improved block finality and reduced confirmation times—key advantages for dApp developers and enterprise users.
Delphi Upgrade (2020)
The Delphi upgrade slashed gas fees by approximately 75%, significantly boosting transaction efficiency and lowering barriers for DeFi applications on the network.
These upgrades highlight how Tezos can modernize core components—including consensus mechanisms—without disrupting network continuity.
Smart Contracts and Developer Ecosystem
Tezos supports smart contracts written in Michelson, a low-level, stack-based language designed for formal verification—a method that mathematically proves code correctness. This makes Tezos particularly appealing for high-assurance applications like financial systems and legal agreements.
However, developers typically use higher-level languages such as:
- SmartPy
- Ligo
- Archetype
These compile down to Michelson, enabling faster development while retaining security benefits.
The Tezos ecosystem has seen growing adoption in DeFi, with projects like Youves, PlentySwap, and Kolibri offering lending, stablecoins, and automated market makers.

NFTs and Digital Ownership on Tezos
Tezos has emerged as a leading blockchain for NFTs, prized for its low transaction costs and energy efficiency. The network’s eco-friendly profile appeals to artists, collectors, and brands focused on sustainability.
Notable partnerships include:
- Manchester United launching fan engagement NFTs
- Ubisoft experimenting with NFTs in gaming
- Red Bull Racing and McLaren releasing motorsport collectibles
Platforms like objkt.com and Rarible have thriving communities minting and trading digital art on Tezos.
Beyond digital art, Tezos is being used to tokenize real-world assets such as real estate. For example, MountX is leveraging Tezos to fractionalize property ownership in Mexico—opening up investment opportunities in traditionally illiquid markets.
Security, Adoption, and Institutional Use
Tezos’ robust governance and formal verification capabilities have attracted interest from government and regulatory bodies.
In September 2019, France’s National Gendarmerie Cybercrime Unit (C3N) became one of the first public institutions to use Tezos for verifying judicial payments—showcasing its potential in official financial systems.
Its minimal trust requirements also make it suitable for fast, auditable transaction validation across industries—from supply chain tracking to identity management.
Storing and Managing XTZ
Tez (XTZ) can be stored in various wallets:
- Software wallets: Trust Wallet, Galleon, Kukai
- Hardware wallets: Ledger, Trezor (via third-party integrations)
Users can also stake XTZ through delegation to earn passive income. While centralized exchanges like Binance offer staking services, decentralized options provide greater control and alignment with Web3 principles.
Frequently Asked Questions (FAQ)
Q: What makes Tezos different from Ethereum?
A: Unlike Ethereum, which historically relied on hard forks for upgrades, Tezos uses on-chain voting to implement changes seamlessly. It also emphasizes formal verification for smart contracts and operates on a more energy-efficient LPoS model.
Q: Can I stake XTZ with less than 6,000 tokens?
A: Yes! You don’t need 6,000 XTZ to participate. Any amount can be delegated to a baker to earn staking rewards—making participation accessible to all holders.
Q: Is Tezos environmentally friendly?
A: Absolutely. As a proof-of-stake blockchain, Tezos consumes significantly less energy than proof-of-work networks like Bitcoin or pre-merge Ethereum.
Q: What are the main use cases for XTZ?
A: XTZ is used for paying transaction fees, participating in governance votes, baking (validating blocks), and delegating stake to support network security.
Q: How does Tezos handle scalability?
A: While not as scalable as some newer layer-1 chains, Tezos improves performance through protocol upgrades (like Delphi’s fee reductions) and layer-2 solutions under development.
Q: Are Tezos smart contracts secure?
A: Yes. Michelson’s design supports formal verification, allowing developers to mathematically prove that their code behaves as intended—reducing risks of bugs or exploits.
Final Thoughts: The Future of Self-Evolving Blockchains
While Tezos may not dominate in terms of dApp count or daily activity compared to Ethereum, its strength lies in sustainability, governance maturity, and long-term resilience. Its ability to upgrade critical components—like consensus algorithms—without hard forks sets it apart in an industry often plagued by fragmentation.
Backed by real-world adoption in DeFi, NFTs, enterprise solutions, and government use cases, Tezos continues to build an organic community of creators and innovators who value decentralization and user sovereignty.
As regulatory landscapes shift and environmental concerns grow, Tezos’ energy efficiency and self-correcting architecture may prove increasingly valuable.
