As an independent mainnet, Tezos has its own node network, consensus mechanism, smart contract system, and on-chain governance structure. Users can transfer assets and deploy smart contracts on the network, and they can also take part in protocol upgrades and network evolution through on-chain governance.
The biggest feature of Tezos is that it brings “protocol upgrades” directly into the on-chain governance process. When traditional blockchains modify protocol rules, developers, validators, and community members often need to coordinate upgrades off-chain. When consensus cannot be reached, a hard fork may occur, and the result can even be two separate blockchains.

What Is Tezos (XTZ)
Unlike many traditional blockchains, Tezos was not designed with transaction speed or throughput as its only priority. Instead, it focuses more on the question of “how a blockchain protocol can evolve over the long term.” Tezos introduced the concept of a “Self-Amending Blockchain.” Its core idea is to let protocol upgrades happen directly through on-chain governance, rather than repeatedly relying on off-chain community coordination and hard forks.
In many traditional public blockchains, when protocol rules need to be changed, developers, miners, validators, and community members usually have to negotiate together. Once different groups fail to reach agreement, the chain may split, and in some cases, it may develop into two independent blockchains. While this can push different technical paths forward, it can also fragment ecosystem resources, intensify community conflict, and increase uncertainty across the network.
Tezos tries to build this “upgrade capability” directly into the protocol itself. Network participants can submit upgrade proposals, the community can vote on-chain to decide whether to accept the changes, and once a proposal passes, the protocol can automatically carry out the upgrade. For this reason, Tezos has long been known as a “Self-Amending Blockchain.”
At the same time, XTZ is the native asset of the Tezos network. It is mainly used to pay transaction fees, participate in network governance, help secure the chain, and take part in the Baking, or validation, mechanism. Users can run their own nodes to participate in network consensus, or they can participate in validation and governance through delegation.
As a result, Tezos is not positioned merely as an ordinary smart contract platform. It is a governance-oriented Layer1 infrastructure that places greater emphasis on governance design, protocol upgradeability, and long-term stability.
The Development Background of Tezos: Why Blockchains Need On-Chain Governance and Protocol Upgrades
In the early development of the blockchain industry, protocol upgrades were always a highly complex issue. Both Bitcoin and Ethereum have experienced community disagreements over protocol changes during their long-term operation. Questions such as whether block size should be expanded, how fee mechanisms should be adjusted, whether consensus rules should be changed, and how network scaling should move forward can all lead to prolonged disputes.
When different groups cannot reach agreement, blockchains often move upgrades forward through hard forks. A hard fork is essentially a change in network rules that ultimately creates two mutually incompatible chains. Although this mechanism can support technical progress, it can also lead to community division, fragmented development resources, and confusion around user asset management.
Tezos proposed on-chain governance against this backdrop. Its central idea is that if protocol upgrades themselves can be completed on-chain, then many issues that originally depended on off-chain negotiation can instead be handled through a standardized governance process. For this reason, Tezos treated governance as part of the protocol from the beginning, rather than as an added feature introduced later.
At the same time, Tezos also adopts a relatively modular network structure. Its Network Shell is separate from the blockchain protocol itself. In simple terms, the underlying network is responsible for node communication and chain synchronization, while the specific protocol rules can be replaced and upgraded through governance. This structure also makes it easier for Tezos to support long-term protocol evolution without frequently relying on aggressive hard forks.
An Explanation of Tezos’ Liquid Proof of Stake (LPoS) Mechanism
Tezos uses Liquid Proof of Stake (LPoS), a PoS consensus structure that emphasizes flexible delegation and open participation. Compared with traditional PoS networks, LPoS places more emphasis on separating validation rights from asset control.
In the Tezos network, validators are known as Bakers. Their main responsibilities include producing new blocks, validating transactions, participating in governance voting, and maintaining network security. Users who hold XTZ can either run their own Baker nodes or delegate their validation rights to other Bakers to participate in network consensus.
This Delegation mechanism is one of the key differences between Tezos and many PoS networks. In Tezos, users do not need to actually transfer their assets to a validator when they delegate. They still retain control over their XTZ, while simply authorizing a Baker to use the corresponding stake for validation and governance. Because of this, Tezos’ LPoS is closer to a form of “liquid staking” structure.
At the same time, Tezos’ consensus mechanism also pays more attention to low energy consumption and long-term stability. Compared with traditional PoW mining, LPoS does not require large amounts of computing power, so its overall energy consumption is significantly lower. This structure has also kept Tezos active for a long time in ESG and green blockchain narratives.
In addition, Tezos’ Network Shell prioritizes maintaining the best chain and filtering out low-quality forks. Compared with structures that maintain a full fork tree, this mechanism can reduce the risk of malicious nodes launching attacks through large numbers of low-scoring forks. Therefore, Tezos’ LPoS is not only a consensus mechanism. It is also closely connected to network security, governance design, and long-term protocol stability.
How Tezos’ On-Chain Governance Mechanism Works
On-chain governance is one of the most representative core designs of Tezos. When many blockchains upgrade their protocols, they usually rely on development teams, community forums, and off-chain negotiation to make decisions. Tezos, by contrast, tries to write the entire upgrade process directly into the protocol itself.
In the Tezos network, developers or community members can submit protocol upgrade proposals, while nodes participating in Baking can vote on-chain to decide whether to support those proposals. When a proposal receives enough support, the network automatically enters the testing and upgrade stage and eventually completes the protocol replacement.
This structure means that protocol upgrades follow a relatively standardized process. Compared with upgrade methods that depend on prolonged community bargaining, Tezos places greater emphasis on “gradual protocol updates,” aiming to reduce the risk of disruptive forks through continuous small-scale upgrades.
This is also why Tezos has long been referred to as a “Self-Amending Blockchain.” Its core logic is not to eliminate disagreement entirely, but to reduce the likelihood of ecosystem fragmentation during upgrades through on-chain governance.
However, on-chain governance does not mean every problem disappears automatically. In practice, governance efficiency, voter participation, and interest coordination remain long-term challenges for all governance-oriented public blockchains. Tezos is therefore better understood as an exploration of a more institutionalized path for protocol evolution, rather than a system that completely removes governance conflict.
Summary
Tezos (XTZ) is a Layer1 blockchain that emphasizes on-chain governance, self-amending mechanisms, and long-term protocol evolution. Compared with many public blockchains that focus mainly on performance scaling, Tezos places greater importance on governance structure, protocol stability, and sustainable upgradeability.
From LPoS consensus and on-chain governance to Formal Verification and financial-grade smart contract design, Tezos represents a blockchain development path that leans toward “governance-oriented infrastructure.”
