How Does Tezos Work?

Tezos is a public blockchain designed to process cryptocurrency transactions, run smart contracts, and support decentralized applications. Its native cryptocurrency, XTZ (tez), is used for network fees, staking, delegation, and participation in the network’s governance. Tezos is particularly known for combining proof-of-stake consensus with an on-chain system for upgrading the protocol.

What Is the Tezos Blockchain?

Tezos is a programmable blockchain that supports ordinary XTZ transfers as well as smart contracts. A transaction can transfer tez between accounts, while a decentralized application can call a smart contract’s predefined entry point to operate.

Tezos uses the Octez software implementation to operate nodes and interact with the protocol. Smart-contract accounts are distinct from ordinary user accounts, and deployed contracts contain code and persistent storage that determine how they respond to calls.

The blockchain’s protocol itself can also change through its governance system, allowing the network’s rules to evolve.

How Does Tezos Work?

At a basic level, Tezos consists of a distributed network of computers that maintain a shared blockchain. Users submit operations such as transactions or smart-contract calls. Network participants called bakers take part in producing and validating blocks, while XTZ provides the economic stake used in consensus.

Tezos also includes smart contracts and a built-in governance mechanism. The latter allows protocol amendments to be proposed, tested, voted on, and activated through the blockchain rather than requiring every upgrade to occur through a conventional hard fork.

How Does Tezos Proof-of-Stake Work?

Tezos uses proof-of-stake to determine which network participants can produce blocks and attest to them. Participants known as delegates or bakers temporarily stake XTZ as a security deposit. Their baking power depends on their staking balance, which includes their own stake and stake provided by other participants.

A baker selected to produce a block proposes it, while other consensus participants can attest that the block is valid. These activities provide the mechanism through which the network reaches agreement without relying on a central operator.

Misbehavior can have economic consequences. For example, double-signing blocks or attestations can result in slashing of staked funds.

What Are Tezos Bakers and Delegators?

A baker operates the infrastructure needed to participate directly in Tezos consensus. Bakers produce blocks and participate in attestation.

A delegator assigns voting and delegation rights to a baker without transferring ownership of their XTZ. Under the current protocol, delegation contributes less baking power than directly staked XTZ and does not subject delegated funds to the same frozen-stake slashing exposure.

This differs from the older Tezos model, in which delegation was primarily associated with receiving rewards distributed by bakers. Current documentation distinguishes delegation from the newer native staking mechanism.

How Does Tezos Staking Work?

Under the current staking model, XTZ holders can stake toward a delegate’s security deposit. Staked XTZ is temporarily frozen and contributes fully to the delegate’s baking power. Participation rewards are distributed by the protocol, while the staked balance can be subject to penalties for certain consensus violations.

Tezos also uses Adaptive Issuance. Instead of relying on one permanently fixed issuance rate, participation issuance responds to the network’s staked ratio, with the protocol targeting a 50% staked ratio under its current design.

Staking rewards therefore depend on protocol parameters and participation and should not be interpreted as guaranteed income.

How Do Smart Contracts Work on Tezos?

Tezos smart contracts are programs stored on the blockchain. Users or other contracts can call their entry points, supplying parameters that cause the predefined code to execute and potentially change the contract’s storage.

Michelson is Tezos’ base smart-contract language. Developers can also use higher-level languages such as SmartPy and LIGO, which compile to Michelson.

Smart contracts make applications such as decentralized exchanges and other blockchain services possible, but bugs or design errors can create technical and financial risks.

How Does Tezos On-Chain Governance Work?

Tezos has a built-in self-amendment process. Under the current documented process, protocol amendments move through five stages: proposal, exploration, cooldown, promotion, and adoption. Each stage allows participants to propose, vote on, test, or prepare for a protocol change.

The exact voting rules and protocol parameters can themselves change through subsequent amendments. Therefore, current Tezos documentation should be consulted when analyzing a particular governance proposal or upgrade.

How Does XTZ Work Within the Tezos Network?

XTZ serves several functions:

• Paying transaction and network-related fees
• Participating in staking and delegation
• Providing economic security for consensus
• Contributing to governance voting power
• Interacting with smart contracts and decentralized applications

XTZ’s network utility is separate from its market price. The existence of these functions does not establish how the token will perform in financial markets.

Tezos combines proof-of-stake consensus, staking and delegation, smart contracts, and on-chain governance within one blockchain system. Bakers help produce and validate blocks, XTZ provides the economic stake and utility needed by the network, smart contracts enable programmable applications, and governance allows protocol rules to evolve.

Tezos continues to change through protocol upgrades. For example, the Ushuaia upgrade activated in June 2026 increased Layer 1 data-availability bandwidth and was adopted through Tezos’ on-chain governance process.

For anyone studying how Tezos works, the most important concepts are its proof-of-stake consensus, current staking model, smart-contract architecture, XTZ utility, and self-amending governance. Because protocol mechanics can change through upgrades, current technical documentation remains the appropriate reference for specific rules and parameters.
