Tezos is a distinctive blockchain project renowned for its built-in on-chain governance mechanism that facilitates network upgrades. This system allows changes to be proposed by users holding a certain amount of Tez (XTZ), followed by community voting. As a result, Tezos can implement seamless upgrades without requiring hard forks, setting it apart in the competitive smart contract platform sector.
Understanding Tezos and Its Core Features
Tezos is a blockchain that supports decentralized applications (dApps) and smart contracts. Its initial concept emerged in 2014, and the mainnet launched in 2018. Since then, Tezos has experienced steady growth, positioning itself as a notable competitor to networks like Ethereum.
The ecosystem is supported by global entities, including the Tezos Foundation—a Swiss non-profit dedicated to promoting awareness and adoption of the blockchain. Tezos raised $232 million in its 2017 fundraising event, making it one of the largest blockchain project fundraisers at the time.
How Tezos Works: Liquidity Proof-of-Stake (LPoS)
Tezos operates on a Proof-of-Stake (PoS) consensus model, specifically a variant known as Liquidity Proof-of-Stake (LPoS). Here’s how it works:
- Users holding over 6,000 XTZ can become "bakers." Bakers create, sign, and add new blocks to the blockchain, and endorse blocks created by others.
- Those with fewer Tez or without the technical resources to run baking infrastructure can delegate their tokens to bakers, earning rewards in the process.
Smart contracts on Tezos are written in Michelson, a language unique to the platform. Developers often use higher-level languages like SmartPy, Ligo, or Archetype, which compile into Michelson. All transactions require gas fees, paid in Tez (XTZ).
The Advantages of Tezos' On-Chain Governance
One of Tezos' most significant innovations is its self-amending capability. Through its on-chain governance process, stakeholders can propose and vote on upgrades. This approach:
- Eliminates the need for hard forks, avoiding community splits (like Bitcoin Cash's split from Bitcoin).
- Allows the network to adapt quickly to regulatory changes and technological advancements.
- Encourages active community participation in the evolution of the protocol.
Major Upgrades and Real-World Impact
Tezos has undergone several successful upgrades, demonstrating its agility:
- Delphi Upgrade (November 2020): Reduced gas fees by approximately 75%, enhancing DeFi development on the network.
- Ithaca 2 Upgrade (April 2022): Replaced the consensus algorithm with "Tenderbake," improving finality and reliability.
These upgrades reflect Tezos' ability to implement significant changes efficiently, even replacing core components without disrupting network operations.
Use Cases and Adoption of Tezos
Tezos is being utilized in various sectors, showcasing its versatility:
- Government Use: France's National Gendarmerie Cybercrime Division (C3N) uses Tezos to verify judicial expenses.
- Real-World Asset Tokenization: Companies like MountX are tokenizing real estate in Mexico using Tezos.
- NFTs and Brand Partnerships: Major brands, including Manchester United, Ubisoft, and McLaren, have engaged with the Tezos NFT ecosystem.

Storing and Staking Tez (XTZ)
Tez can be stored in popular software wallets like Trust Wallet or hardware wallets such as Ledger and Trezor. For those interested in earning rewards, staking options are available through delegation to bakers or via institutional platforms.
Frequently Asked Questions
What makes Tezos different from Ethereum?
Tezos uses an on-chain governance model and self-amending mechanism to avoid hard forks, whereas Ethereum relies off-chain consensus for upgrades. Tezos also uses LPoS, while Ethereum transitioned to PoS with its Ethereum 2.0 upgrade.
How can I participate in Tezos governance?
To vote on proposals, you need to hold or delegate XTZ. Users with 6,000 or more XTZ can become bakers and propose changes directly.
Is Tezos energy-efficient?
Yes. Tezos' LPoS consensus consumes significantly less energy than Proof-of-Work blockchains, making it an environmentally friendly option.
What is the role of the Tezos Foundation?
The Tezos Foundation is a non-profit organization that supports the growth, awareness, and adoption of the Tezos blockchain through grants and partnerships.
Can I develop dApps on Tezos?
Absolutely. Tezos supports smart contracts and dApp development using languages like SmartPy and Ligo, with extensive documentation and community resources available.
How secure is the Tezos network?
Tezos has a strong security record, with its baking process and formal verification of smart contracts contributing to its reliability.
Conclusion
Though Tezos may not yet match Ethereum in network activity or dApp volume, its unique governance model, energy efficiency, and adaptability offer compelling long-term advantages. It has fostered an organic community of creators and attracted institutional interest, proving its utility and resilience in the evolving blockchain landscape.
