Introduction to Tezos

Origins and Founders

Tezos is a groundbreaking blockchain platform that came into existence in 2017. It was founded by Arthur Breitman and Kathleen Breitman, a dynamic husband-and-wife team with extensive backgrounds in computer science, finance, and strategy consulting. The project successfully raised over $230 million during its initial coin offering (ICO), making it one of the largest ICOs at the time.

Purpose of Tezos

The primary goal of Tezos is to create a truly decentralized and self-governing blockchain platform. Its focus is on facilitating secure and scalable decentralized applications (dApps) and smart contracts. One of the unique selling points of Tezos is its ability to evolve and adapt through its innovative governance model, which allows the community to actively participate in decision-making processes and protocol upgrades.

Key Features

Tezos offers a range of distinctive features that set it apart from other blockchain platforms. Some of the most prominent features include:

  • Liquid Proof-of-Stake (LPoS): Tezos uses a unique consensus mechanism called Liquid Proof-of-Stake, which allows token holders to participate in the validation of transactions and earn rewards through staking or delegation. This mechanism is designed to be more energy-efficient and secure compared to traditional Proof-of-Work systems.
  • Self-Amending Protocol: Tezos is designed to evolve and adapt through its self-amending feature. This allows the community to propose and vote on changes to the protocol, effectively enabling on-chain upgrades without the need for hard forks.
  • Michelson Smart Contracts: Tezos uses a custom-built programming language called Michelson for its smart contracts. Michelson is a stack-based, statically-typed language that aims to enhance security and formal verification, making it easier for developers to create secure and reliable dApps.
  • Strong Governance Model: The Tezos governance model empowers its community by allowing stakeholders to have a say in the platform’s development and upgrades. This model promotes decentralization and ensures that Tezos remains agile and adaptive to the rapidly evolving blockchain landscape.

By combining these unique features, Tezos aims to provide a robust, secure, and adaptive blockchain platform that caters to the diverse needs of developers, users, and businesses alike.

Tezos Blockchain Architecture

Layered Architecture

Tezos has a modular and layered architecture, which separates various aspects of the blockchain into distinct layers. This design approach enhances flexibility, facilitates upgrades, and allows for more effective management of the platform. The three primary layers in the Tezos architecture are the network, consensus, and transaction layers.

Network, Consensus, and Transaction Layers

  • Network Layer: The network layer is responsible for managing communication between nodes, propagating transactions, and maintaining the distributed ledger. Tezos employs a peer-to-peer (P2P) network with a focus on reliability and efficiency. This layer utilizes a gossip protocol for communication, ensuring that information is transmitted quickly and securely throughout the network.
  • Consensus Layer: At the core of the Tezos platform is its innovative Liquid Proof-of-Stake (LPoS) consensus mechanism. The consensus layer governs the process of validating transactions, proposing and endorsing blocks, and achieving consensus among participating nodes. LPoS provides an energy-efficient and secure alternative to traditional Proof-of-Work systems while allowing for decentralized governance and stakeholder involvement.
  • Transaction Layer: The transaction layer is where smart contracts and transactions are executed. This layer interprets and processes the Michelson programming language, which is specifically designed for Tezos smart contracts. The transaction layer also handles the creation and management of accounts, token transfers, and other on-chain operations.

Smart Contracts

Smart contracts are self-executing agreements that run on a blockchain platform. They are designed to facilitate, verify, and enforce contractual agreements without the need for intermediaries. On the Tezos platform, smart contracts are written in the Michelson programming language, which is designed to prioritize security, accuracy, and formal verification.

The Tezos smart contract ecosystem enables developers to create decentralized applications (dApps) with a wide range of use cases, such as decentralized finance (DeFi), non-fungible tokens (NFTs), and asset tokenization. By providing a reliable and secure environment for smart contracts, Tezos aims to foster the development of innovative solutions and drive the adoption of blockchain technology across various industries.

Tezos' Liquid Proof-of-Stake (LPoS) Consensus Mechanism

How LPoS Works

Tezos’ Liquid Proof-of-Stake (LPoS) is a unique consensus mechanism that combines elements of both Proof-of-Stake (PoS) and Delegated Proof-of-Stake (DPoS) systems. LPoS strikes a balance between decentralization, security, and energy efficiency by allowing XTZ token holders to participate in the validation process either by staking their tokens or delegating their staking rights to others.

Baking and Endorsing Blocks

In the Tezos ecosystem, the process of validating and adding new blocks to the blockchain is called “baking.” Bakers are selected randomly based on the number of XTZ tokens they hold, also known as their “roll size.” Each roll consists of 8,000 XTZ, and the more rolls a baker has, the higher the chance they have to be selected for baking a new block.

When a baker is chosen, they create a new block containing a set of transactions and add it to the blockchain. The process doesn’t end here – the new block must also be endorsed by a group of endorsers, who are also selected based on their roll size. Endorsers verify the validity of the newly baked block, and once they approve it, the block becomes part of the Tezos blockchain.

Both bakers and endorsers receive rewards for their participation in the form of newly minted XTZ tokens. This incentivizes token holders to actively engage in the baking and endorsing processes, thereby contributing to the network’s security and decentralization.

Staking and Delegation

Not all XTZ token holders can become bakers, as it requires a minimum of 8,000 XTZ to form a roll. To ensure that smaller token holders can still participate in the validation process and earn rewards, Tezos allows for delegation. Delegation enables token holders to delegate their staking rights to a baker without transferring ownership of their tokens.

Delegators can choose from a variety of bakers, each with its own fee structure and performance metrics. Once delegated, the baker includes the delegated tokens in their roll size, increasing their chances of being selected for baking and endorsing. In return, the baker shares a portion of the rewards with their delegators, allowing everyone to benefit from the network’s growth and security.

Governance and Protocol Upgrades

One of the standout features of Tezos’ LPoS mechanism is its ability to facilitate on-chain governance and protocol upgrades. Token holders can submit proposals for changes to the protocol, which are then voted on by bakers. If a proposal receives enough support, it moves through a series of voting periods before being integrated into the Tezos blockchain.

This self-amending process ensures that Tezos can evolve and adapt to the ever-changing blockchain landscape without the need for hard forks or contentious debates. It empowers the community to shape the platform’s future, fostering a truly decentralized and self-governing ecosystem.

XTZ: The Native Token of Tezos

Tokenomics

XTZ, also known as “tez” or “tezzies,” is the native cryptocurrency of the Tezos blockchain. The token plays a vital role in the network’s operations, such as securing the platform, incentivizing participation, and facilitating transactions. The tokenomics of XTZ are designed to promote a healthy and sustainable ecosystem, encouraging long-term growth and stability.

Distribution and Supply

Tezos had an initial coin offering (ICO) in July 2017, raising over $230 million from investors worldwide. During the ICO, approximately 607 million XTZ tokens were distributed to investors. In addition to the initial distribution, the Tezos protocol has an inflationary model, with new tokens being minted as rewards for bakers and endorsers.

The annual inflation rate of XTZ is around 5.5%, but it is worth noting that this rate is offset by the rewards earned by token holders who participate in the baking and endorsing processes. As a result, the effective inflation rate experienced by active participants is lower than the nominal rate.

Role in the Tezos Ecosystem

XTZ tokens serve multiple purposes within the Tezos ecosystem:

  • Securing the Network: Token holders can participate in the baking and endorsing processes by staking or delegating their XTZ, contributing to the platform’s security and decentralization.
  • Incentivizing Participation: Bakers and endorsers earn rewards in the form of newly minted XTZ tokens, incentivizing them to actively engage in the validation process and maintain the network’s integrity.
  • On-chain Governance: XTZ token holders have a say in the platform’s governance by voting on proposals for protocol upgrades and changes, fostering a truly decentralized and self-governing ecosystem.
  • Fueling Transactions and dApps: XTZ tokens are used to pay for transaction fees and interact with decentralized applications (dApps) built on the Tezos platform.

Exchange Availability

As a popular and widely recognized cryptocurrency, XTZ is available for trading on various cryptocurrency exchanges, including major platforms like Binance, Coinbase, Kraken, and Bitfinex. Users can trade XTZ against other cryptocurrencies like Bitcoin (BTC), Ethereum (ETH), and stablecoins such as USD Coin (USDC) or Tether (USDT). Additionally, some exchanges offer fiat-to-crypto trading pairs, allowing users to buy XTZ directly with traditional currencies like USD or EUR.

To store XTZ tokens securely, users can choose from a range of wallets that support Tezos, including hardware wallets like Ledger and Trezor, as well as software wallets such as Galleon, Kukai, and TezBox.

Tezos Governance and On-Chain Upgrades

Self-Amendment Process

Tezos stands out among blockchain platforms for its built-in self-amendment process, which enables the network to undergo protocol upgrades without the need for hard forks. This feature promotes a more efficient, cohesive, and democratic approach to making changes, as it allows the Tezos community to propose, vote on, and implement upgrades directly on the blockchain.

Voting and Proposal Periods

Tezos’ on-chain governance process consists of four distinct voting periods:

  1. Proposal Period: During this phase, which lasts eight cycles (approximately three weeks), bakers can submit proposals for changes or upgrades to the Tezos protocol. Each baker can submit up to 20 proposals, and any proposal must receive support from at least 0.1% of the total rolls to proceed to the next stage.
  2. Exploration Vote Period: This phase also lasts eight cycles, and bakers vote on the proposals submitted during the proposal period. A proposal must receive support from at least 80% of the participating rolls to advance to the next phase. If multiple proposals meet this requirement, the one with the most support moves forward.
  3. Testing Period: In this phase, which lasts four cycles (approximately two weeks), a testnet fork of the Tezos blockchain is created to evaluate and test the proposed changes. This allows the community to assess the potential impact and effectiveness of the proposal before it is integrated into the mainnet.
  4. Promotion Vote Period: The final stage lasts eight cycles, during which bakers vote on whether to adopt the tested proposal into the mainnet. If the proposal garners support from at least 80% of the participating rolls, it becomes part of the Tezos protocol.

On-Chain Upgrades without Hard Forks

One of the key benefits of Tezos’ on-chain governance process is that it eliminates the need for hard forks to implement protocol upgrades. Hard forks can be contentious and lead to network splits, creating uncertainty and instability in the blockchain ecosystem. Tezos’ self-amendment process allows for seamless, consensus-driven upgrades that keep the community united and the platform evolving smoothly.
