Tezos is a self-governing blockchain platform designed to enable decentralized decision-making and seamless network upgrades through on-chain governance. At the heart of its innovation lies the XTZ token, which empowers users to vote on protocol changes, ensuring that the evolution of the network remains community-driven. This unique model sets Tezos apart in the rapidly expanding world of blockchain technology.
Unlike traditional blockchains that often face divisive hard forks during upgrades, Tezos uses a built-in governance mechanism that allows stakeholders to propose, debate, and approve changes without splitting the network. This feature not only enhances stability but also increases long-term sustainability and user trust.
The Core Mechanics of Tezos
The Tezos blockchain operates using a two-layer architecture composed of the network shell and the network protocol:
- The network shell manages transactions, consensus, and governance functions. It has the ability to upgrade itself based on community voting outcomes.
- The network protocol is responsible for submitting upgrade proposals and maintaining core blockchain logic.
This modular design enables Tezos to evolve organically while preserving security and decentralization.

Liquid Proof-of-Stake (LPoS): A Flexible Consensus Model
Tezos does not rely on energy-intensive mining. Instead, it uses Liquid Proof-of-Stake (LPoS), a variation of the standard Proof-of-Stake (PoS) mechanism. In LPoS, users can participate in securing the network by "baking" — the term Tezos uses for validating blocks.
To become a full baker, a node must stake at least 8,000 XTZ. However, users with smaller holdings can still contribute by delegating their XTZ to an existing baker without transferring ownership. This delegation process makes staking accessible and inclusive.
Bakers are rewarded with newly minted XTZ tokens for creating blocks and participating in governance votes, creating strong economic incentives for honest behavior.
Governance in Action: How Upgrades Are Decided
One of Tezos’ most groundbreaking features is its formalized on-chain governance process, which unfolds over four distinct 23-day voting periods:
- Proposal Period: Any baker can submit upgrade suggestions. Proposals with the most support advance.
- Exploration Vote Period: The community votes on whether to explore the top proposals further. A supermajority (80%) is required to proceed.
- Testing Period: Approved proposals are tested on a temporary fork to evaluate performance and security.
- Promotion Vote Period: Final approval is determined by another 80% supermajority vote. If passed, the change is automatically implemented.
This structured approach minimizes disruption and ensures broad consensus before any modification takes effect.
Additionally, bakers who submit beneficial proposals can attach an invoice to receive compensation if their upgrade is adopted — incentivizing innovation and active participation.
Founders and History of Tezos
Tezos was conceived in 2014 by Arthur Breitman and Kathleen Breitman, a husband-and-wife team with strong backgrounds in mathematics, finance, and technology. Arthur, a former engineer at Google and quantitative analyst at Morgan Stanley, authored the original whitepaper under the pseudonym “L.M. Goodman.”
The project was formally launched through a nonprofit entity based in Switzerland — the Tezos Foundation — which oversaw its initial funding.
The Record-Breaking ICO and Early Challenges
In July 2017, Tezos conducted one of the most successful initial coin offerings (ICOs) in history, raising $232 million in just two weeks by accepting both Bitcoin and Ether. Despite this financial success, the project faced significant internal conflicts shortly after launch.
A legal dispute emerged between the Breitmans and Johann Gevers, then-president of the Tezos Foundation, over control of funds and project direction. This controversy delayed development and attracted negative media attention. However, after legal settlements and governance reforms, the team regained momentum and successfully launched the mainnet in 2018.
What Makes Tezos Unique?
Several key innovations define Tezos’ value proposition:
- On-chain governance: Unlike many blockchains that rely on informal off-chain discussions (e.g., Bitcoin or Ethereum pre-upgrades), Tezos formalizes decision-making directly within the protocol.
- Self-amending capability: The network upgrades itself without requiring hard forks, reducing fragmentation risk.
- Decentralized control: Power rests with token holders, promoting fairness and inclusivity.
- Energy efficiency: As a PoS-based chain, Tezos consumes minimal energy compared to proof-of-work systems.
These attributes make Tezos particularly appealing to developers, enterprises, and environmentally conscious investors.

What Gives Tezos Value?
Tezos derives value from both utility and ecosystem adoption:
- The XTZ token is essential for staking (baking), paying transaction fees, and participating in governance.
- Enterprises use Tezos to tokenize real-world assets such as stocks, real estate, and funds. Notable partners include Securitize, Elevated Returns, BTG Pactual, and tZero.
- Its low transaction costs and high throughput support scalable decentralized applications (dApps).
As more institutions adopt blockchain-based asset issuance, Tezos’ role as a compliant, upgradable platform strengthens its long-term relevance.
Supply and Inflation Metrics
Tezos has no fixed maximum supply. As of now, the circulating supply is approximately 762 million XTZ. New tokens are issued at a rate of about 80 XTZ per block, resulting in an annual inflation rate of roughly 5.51%.
Rewards are distributed to bakers and delegators, encouraging network participation and securing the chain against attacks.
Security Architecture
Tezos prioritizes security through:
- Full decentralization with no single point of failure.
- Cryptographic encryption for data integrity.
- Economic incentives aligned with honest behavior via LPoS.
Because changes require broad stakeholder approval, malicious actors cannot alter the protocol without overwhelming consensus — making attacks economically unfeasible.
Practical Uses of Tezos Today
While still growing in adoption, Tezos supports several real-world applications:
- Staking (baking): Users earn passive income by securing the network.
- dApp development: Projects like tzBTC (a Bitcoin-wrapped token) and Tezsure (decentralized insurance) operate on Tezos.
- Digital collectibles and NFTs: Artists and creators use Tezos for minting eco-friendly NFTs.
- Speculative investment: Traders buy XTZ anticipating future growth.
- Payments: Some merchants accept XTZ as a form of payment.
Choosing a Tezos Wallet
Selecting the right wallet depends on your needs:
- Hardware wallets (e.g., Ledger, Trezor): Offer maximum security with offline storage. Ideal for large holdings and experienced users.
- Software wallets: Free apps for desktop or mobile devices. Can be custodial (keys managed by provider) or non-custodial (you control keys). Best for moderate use.
- Web wallets: Accessible via browser; convenient but less secure due to online exposure. Suitable for small balances or frequent traders.
Always prioritize platforms with strong security records when storing digital assets.
Frequently Asked Questions (FAQ)
Is Tezos a competitor to Ethereum?
Yes, to some extent. Both platforms support smart contracts and decentralized applications. However, Tezos differentiates itself with formal on-chain governance and automatic upgrades — features that aim to reduce community splits and improve long-term adaptability.
Is XTZ delegation safe?
Yes. When you delegate XTZ to a baker, you retain full ownership of your tokens. The baker can only use your stake for validation purposes and cannot access or transfer your funds.
When does an XTZ baker start earning rewards?
New bakers must wait approximately 35 days for their first cycle of approval. After that, rewards are distributed roughly every three days, depending on baking performance and network conditions.
Can I mine Tezos?
No. Tezos does not use proof-of-work mining. Instead, it relies on Liquid Proof-of-Stake (LPoS), where users bake or delegate XTZ to earn rewards.
What are some notable projects built on Tezos?
Popular dApps include tzBTC (a Bitcoin pegged token), Kalamint (NFT marketplace), StakerDAO (decentralized asset management), and Plenty Network (DeFi exchange).
How often are protocol upgrades voted on?
Upgrade cycles occur approximately every three months (four 23-day periods). However, proposals can be submitted at any time by eligible bakers.
