Tezos (XTZ) has emerged as a powerful contender in the blockchain space, offering a unique blend of innovation, governance, and scalability. Designed to support decentralized applications (DApps) and smart contracts, Tezos stands out with its self-amending blockchain and on-chain governance model. This guide explores everything you need to know about Tezos — from its technology and history to how to buy and store XTZ securely.
What Is Tezos (XTZ)?
Tezos is an open-source, decentralized blockchain network that enables the development of secure smart contracts and DApps. Unlike traditional blockchains that require hard forks for upgrades, Tezos uses a self-correcting ledger mechanism that allows seamless protocol upgrades through community-driven voting.
The native cryptocurrency of the Tezos ecosystem is XTZ, often referred to by enthusiasts as "tez" or "tezzie." With approximately 940 million XTZ in circulation, the platform maintains flexibility by not setting a fixed maximum supply — a strategic decision aimed at long-term adaptability.

The History of Tezos
Tezos was conceived in 2014 by Arthur and Kathleen Breitman, who sought to build a more adaptable and mathematically secure blockchain. Their vision led to the creation of a network that combines formal verification methods with a liquid proof-of-stake (LPoS) consensus mechanism.
In 2017, Tezos raised $232 million in one of the largest initial coin offerings (ICOs) at the time — a record-breaking event that captured global attention. However, shortly after, internal disputes arose between the Breitmans and Johann Gevers, then-president of the Tezos Foundation. The conflict centered around fund disbursement and leadership control, temporarily shaking investor confidence.
Despite these early setbacks, the project recovered. Funds were eventually released, Gevers stepped down, and development resumed. Today, Tezos operates under the oversight of the Tezos Foundation, a Swiss-based nonprofit dedicated to promoting and supporting the protocol's growth through grants and ecosystem initiatives.
How Does Tezos Work?
Tezos differentiates itself through several technical innovations that enhance security, scalability, and decentralization.
Liquid Proof-of-Stake (LPoS)
At the core of Tezos’ architecture is its Liquid Proof-of-Stake (LPoS) consensus mechanism. Unlike traditional PoS systems, LPoS allows token holders to participate in network validation either directly or by delegating their stake to validators — known as "bakers."
Key advantages of LPoS include:
- Full user control over voting rights
- No need to transfer ownership when delegating
- Ability to reassign or reclaim voting power at any time
- Incentivized participation through baking rewards and transaction fees
To become a baker, users must hold at least 6,000 XTZ (a "roll") and run the necessary infrastructure. However, even small stakeholders can earn rewards by delegating their tokens to trusted bakers.
On-Chain Governance
One of Tezos’ most revolutionary features is its on-chain governance system, which eliminates the need for contentious hard forks. When developers propose an upgrade:
- The community reviews and tests the proposal across multiple cycles.
- XTZ holders vote on whether to adopt the change.
- If approved, the update is automatically integrated into the network via a "hot swap."
This structured approach ensures continuous evolution while maintaining network stability and community alignment.
Smart Contract Security and Flexibility
Tezos supports smart contract development using Michelson, a functional programming language designed for formal verification — a method that mathematically proves code correctness. This makes Tezos particularly attractive for financial institutions and enterprises requiring high assurance in contract integrity.
Additionally, the platform leverages OCaml for core protocol development, enhancing performance and reliability.
Currently, Tezos can process around 1,000 transactions per second (tps), with potential for further improvement through layer-2 scaling solutions and future protocol upgrades.
Why Is Tezos Important?
Tezos addresses key limitations found in earlier blockchains:
- Self-upgrading capability prevents network splits
- Decentralized governance empowers stakeholders
- High security standards via formal verification
- Energy efficiency thanks to LPoS
These features make Tezos a compelling choice for developers building regulated financial products, NFT marketplaces, and enterprise-grade DApps.

Tezos Account Types
Tezos supports two primary account types:
Implicit Accounts
- Begin with
tz1,tz2, ortz3 - Used for holding XTZ and making transfers
- Controlled directly by private keys
- Ideal for everyday users
Originated Accounts
- Start with
KT1 - Created by smart contracts
- Can hold funds, manage delegations, and execute logic
- Often used for multisig wallets or DAO treasuries
Understanding these distinctions helps users choose the right tools for their needs — whether managing personal funds or deploying complex decentralized applications.
Where to Buy Tezos (XTZ)
XTZ is widely available on major cryptocurrency exchanges, including:
- Coinbase: Listed on NASDAQ, serving over 100 countries
- Kraken: Trusted platform operating since 2011, available in Europe, North America, and beyond
- Uphold: Offers extensive crypto options for U.S. residents (excluding Germany and Netherlands)
When selecting an exchange, consider factors like fees, regulatory compliance, security measures, and user experience.
How to Store XTZ Safely
For long-term holders or significant investors, hardware wallets offer the highest level of security. These devices store private keys offline — protecting assets from online threats.
Recommended options include:
- Ledger Nano S
- Ledger Nano X
Both support XTZ via Ledger Live and integrate seamlessly with popular software wallets like Temple Wallet and Galleon.
For frequent traders, reputable software wallets provide convenience without compromising too much on security — but always enable two-factor authentication (2FA) and avoid sharing seed phrases.
Frequently Asked Questions (FAQs)
Q: Is Tezos a good investment in 2025?
A: Tezos shows strong potential due to its scalable architecture, active developer community, and growing adoption in DeFi and NFT sectors. As with any crypto investment, conduct thorough research and assess your risk tolerance before investing.
Q: Can I stake XTZ and earn rewards?
A: Yes. Through baking or delegation, XTZ holders can earn annual yields typically ranging from 4% to 6%, depending on network participation and baker performance.
Q: Does Tezos have a maximum supply?
A: No. Tezos does not enforce a hard cap on XTZ supply. Instead, new tokens are minted through baking rewards, ensuring ongoing network incentives.
Q: How is Tezos different from Ethereum?
A: While both support smart contracts, Tezos uses LPoS instead of Ethereum’s PoS, offers built-in governance, avoids hard forks via self-amendment, and emphasizes formal verification for enhanced security.
Q: What are some real-world uses of Tezos?
A: Tezos powers NFT platforms like Objkt.com, central bank digital currency (CBDC) pilots in countries such as Uruguay and Thailand, and enterprise blockchain solutions in finance and supply chain management.
