Tezos (XTZ)

Overview

Tezos is a blockchain for moving digital assets and running applications. Its native currency is called tez, with the ticker XTZ. People use tez to pay network fees, send value, and take part in the system that keeps the blockchain running. Developers can also build smart contracts: programs that carry out agreed rules when someone interacts with them. (docs.tezos.com)

Tezos was designed to change over time. Its upgrade process is built into the blockchain, so participants can propose, test, and vote on changes to its rules. This focus on steady upgrades, along with proof-of-stake validation, shapes how the network works and what developers can build on it. (docs.tezos.com)

History & Team

From idea to launch

Arthur and Kathleen Breitman created Tezos in 2014. The project gained support through a 2017 fundraiser, and the Tezos network launched in 2018. Arthur and Kathleen were central to its early design, while Dynamic Ledger Solutions, or DLS, developed the initial software. Tezos is open-source, and its later development has involved teams and contributors across the wider ecosystem. (docs.tezos.com)

The Swiss-based Tezos Foundation received the fundraiser contributions and supports protocol development, technical infrastructure, and adoption through funding. It acts as a steward of resources rather than an operator that controls the blockchain. The project also faced disputes after the fundraiser. In 2020, the Foundation and other defendants agreed to settle related U.S. class-action lawsuits. (tezos.foundation)

Technology & How It Works

Baking and proof of stake

Tezos uses proof of stake to agree on new blocks. Validators are called bakers. They run software that creates blocks and checks the work of other bakers. The amount of tez supporting a baker helps determine its role in this process. Baking rewards give participants an incentive to keep the network operating. Proof of stake does not require the mining equipment used by proof-of-work systems. (docs.tezos.com)

A holder can support a baker without running a node. Delegation assigns an account’s baking and voting power to a chosen baker while leaving the delegated tez available in the holder’s account. Staking places a chosen amount of tez into the baker’s stake. Staked funds remain in the holder’s account but are locked until the unstaking process is complete. The protocol distributes staking rewards directly; bakers handle any rewards they share with delegators. (tezos.com)

Smart contracts and upgrades

Smart contracts on Tezos run in Michelson, a language designed to make contract behavior precise and open to formal verification. Formal verification uses mathematical methods to check whether a program meets stated requirements. Developers often write in a higher-level language that is then translated into Michelson. The method is especially useful for contracts that manage complex assets or rules. (docs.tezos.com)

Network upgrades pass through stages for proposals, voting, testing, and adoption. Bakers cast votes using power linked to the tez supporting them. When a proposal meets the voting requirements, the network can activate the new rules through its built-in process. One example is Tallinn, an upgrade activated in January 2026 that reduced the time between Tezos layer-1 blocks to six seconds. (docs.tezos.com)

Tezos also supports Smart Rollups. These systems process work outside the main blockchain, then post information back to Tezos so their behavior can be checked. A related Data Availability Layer helps make rollup data accessible. Etherlink uses this design to run applications built for the Ethereum Virtual Machine, or EVM. Its Ganesha upgrade added an interface that lets Michelson and EVM contracts interact within the same transaction. (docs.tezos.com)

Tokenomics & Utility

How tez enters and moves through the network

The initial allocation of tez came from the 2017 fundraiser. Fundraiser participants received the largest share; smaller allocations went to early backers and contractors, DLS, and the Tezos Foundation. The Foundation and DLS allocations vested over four years. Since launch, the protocol has created additional tez as rewards for network participation. (tezos.foundation)

Tezos uses adaptive issuance to adjust participation rewards according to the share of the total tez supply that is staked. In broad terms, the mechanism raises incentives when staking falls below its target range and lowers them when staking rises above it. This ties the creation of new tez to the amount committed to network security. (octez.tezos.com)

Tez has several connected jobs. It pays for transfers and smart-contract activity, supports bakers through staking or delegation, and gives holders a way to take part in protocol governance. Some charges for using blockchain storage are burned, meaning that tez is removed from circulation. Etherlink also uses XTZ as its native coin. These roles link the currency to activity on both Tezos layer 1 and its EVM-compatible layer. (docs.tezos.com)

Ecosystem & Use Cases

Applications built on Tezos

Tezos supports digital art, collectibles, finance applications, games, and asset tokenization. Its FA2 token standard gives developers a shared way to create and manage different kinds of assets, including interchangeable tokens and unique NFTs. A common standard helps wallets and applications recognize those assets and work together. (docs.tezos.com)

An artist, for example, can use a smart contract to record who owns a digital work. A game can issue items that players hold in their own wallets. Finance applications can use contracts to manage exchanges or other programmed transactions. Tokenization projects use the chain to record digital representations of assets such as securities or commodities. In each case, the application defines the asset and its rules; tez pays for activity on the network. (docs.tezos.com)

Etherlink gives developers another route into the ecosystem. Its EVM interface lets them use familiar Ethereum-style tools, while its connection to Tezos supports communication between the two environments. The Ganesha upgrade brought Michelson contracts and EVM contracts together on Etherlink, expanding the ways applications can interact. (docs.tezos.com)

Advantages & Challenges

Tezos’ built-in governance gives the network a clear path for changing its rules. Its proof-of-stake model avoids proof-of-work mining, and Michelson offers tools for developers who want to check contract properties closely. Smart Rollups and Etherlink add room for applications that need more processing capacity or EVM-compatible tools. Together, these features give Tezos several ways to adapt as software needs change. (docs.tezos.com)

The same design brings practical challenges. Voting and testing take time, and larger amounts of supporting tez carry more voting power. Developers building across layer 1 and Etherlink must understand how the systems communicate. Applications also need useful tools and active communities to grow. Tezos’ early organizational disputes form part of its history, while its continuing development depends on participation from bakers, builders, and users. (docs.tezos.com)

Where to Buy & Wallets

XTZ is available for purchase on Coinbase and Kraken, subject to each platform’s location and account requirements. After buying tez, a holder can keep it with the exchange or transfer it to a wallet that supports the Tezos network. (coinbase.com)

Tezos-compatible wallets include Temple, Kukai, Umami, AirGap, and Ledger hardware wallets. Wallets manage the keys used to sign transactions, show account balances, and connect to applications. Their features differ: some focus on browser or mobile use, while others offer desktop access or hardware-based signing. A Tezos layer-1 account and an Etherlink EVM account may use different wallet interfaces, even though both environments use XTZ. (docs.tezos.com)

Regulatory & Compliance

The legal rules that apply to XTZ activity depend on the place and the service involved. In the United States, private lawsuits followed the 2017 fundraiser, and the Tezos Foundation announced a settlement in 2020. In the European Union, the Markets in Crypto-Assets framework sets authorization requirements for firms that provide covered crypto-asset services, including trading and custody. The Tezos Foundation itself is based in Switzerland and is supervised as a Swiss foundation. (tezos.foundation)

Tezos has also received a Shariah compliance assessment. In 2020, Shariyah Review Bureau reviewed features of the Tezos blockchain, including its governance and proof-of-stake system, and announced certification of the platform under its Shariah principles. The assessment concerns the reviewed platform features. Financial products or smart contracts built on Tezos have their own structures and uses, which can be assessed separately. (shariyah.net)

Future Outlook

Tezos’ direction follows from its ability to upgrade both the base network and the systems built around it. The Tezos X effort aims to make Michelson and EVM applications work more closely together. Etherlink’s Ganesha upgrade put a key part of that design into use by enabling direct calls between the two kinds of contracts. Further progress will depend on how developers use those connections and how well the tools support everyday applications. (tezos.com)

The network’s long-term role will also reflect what people choose to build: digital assets, games, financial tools, and other services. Its governance process gives participants a way to respond to new technical needs as those uses develop. (docs.tezos.com)

Summary

Tezos combines a proof-of-stake blockchain, on-chain governance, and smart contracts with an expanding layer-2 system. Tez powers transactions, supports validation, and connects users to the network’s upgrade process. For readers learning about crypto platforms, Tezos is an example of a blockchain built around the idea that its rules and applications can evolve together. (docs.tezos.com)
