Welcome to the wonderful world of Tezos, where you can have your cake and eat it too (or should we say, bake it?). Tezos is not your average blockchain platform; it's a decentralized playground where smart contracts come to life, and you can earn sweet rewards by staking your tokens.
What is Tezos Blockchain Network?
Tezos is a decentralized blockchain platform that allows for the creation and execution of smart contracts and decentralized applications (dApps). It was designed to provide a self-amending governance mechanism, enabling the platform to evolve without requiring hard forks or disruptions.
Tezos was developed by Arthur Breitman and Kathleen Breitman, who launched an initial coin offering (ICO) in 2017, raising one of the largest amounts of funds at that time. The Tezos network officially launched in 2018.
The native cryptocurrency of the Tezos blockchain is called Tezos (XTZ). XTZ holders can participate in the network's governance and earn rewards by staking their tokens. Staking involves locking up XTZ in a wallet to support the consensus mechanism and validate transactions. In return, stakers receive additional XTZ as a reward for their contribution to the network's security and stability.
Tezos has gained attention for its focus on security, formal verification, and governance model. It has been used for various applications, including decentralized finance (DeFi), non-fungible tokens (NFTs), and tokenized assets. The platform also supports multiple programming languages, making it more accessible for developers to build smart contracts and DApps.
Here are some key details about Tezos blockchain:
Consensus Algorithm: Tezos uses a delegated proof-of-stake (DPoS) consensus algorithm called "Liquid Proof-of-Stake" (LPoS). LPoS involves token holders (known as "bakers") staking their Tezos tokens (XTZ) to participate in block validation and creation. This consensus mechanism aims to provide a high level of security and decentralization.
Self-Amendment: Tezos is known for its self-amendment capability, allowing the platform to upgrade and improve itself without the need for hard forks. Through an on-chain governance process, stakeholders can propose and vote on protocol amendments, which can include changes to the network's rules, governance mechanisms, or even the consensus algorithm itself.
Formal Verification: Tezos places a strong emphasis on security and reliability through the use of formal verification. Smart contracts written in Tezos' native programming language, Michelson, can be formally verified to mathematically prove their correctness and the absence of bugs or vulnerabilities. This approach aims to minimize risks and enhance the security of smart contracts on the platform.
Michelson Smart Contract Language: Tezos uses a domain-specific language (DSL) called Michelson to write smart contracts. Michelson is a stack-based language with a strong emphasis on security and formal verification. It provides the flexibility to write complex and expressive smart contracts while maintaining a high level of safety and security.
Liquid Democracy: Tezos employs a liquid democracy-based governance model, allowing token holders to either participate directly in decision-making or delegate their voting power to others. This system aims to promote inclusivity and efficiency in the governance process, as token holders can actively participate or choose trusted delegates to represent their interests.
On-Chain Governance: Tezos' governance process is entirely on-chain, meaning that proposals, voting, and decision-making occur directly within the blockchain. This approach enables stakeholders to actively participate in the governance of the network and ensures transparency and immutability in the decision-making process.
Baking and Endorsement: In Tezos, block validation is performed by "bakers," who are selected based on the number of tokens they hold and their willingness to stake those tokens. Bakers create new blocks and are responsible for including and validating transactions. Additionally, there are "endorsers" who validate blocks by adding their endorsements to the chain. Bakers and endorsers receive rewards for their participation.
Token: XTZ: Tezos has its native cryptocurrency called Tezos (XTZ). XTZ is used for staking, transaction fees, and as a governance token for voting on protocol upgrades. Token holders can delegate their XTZ to bakers without transferring ownership, allowing them to earn staking rewards while maintaining control over their tokens.
Interoperability: Tezos supports interoperability, allowing for the seamless transfer of assets and data between Tezos and other blockchains. This feature enables cross-chain communication and integration with other blockchain networks, expanding the possibilities for decentralized applications and enhancing overall ecosystem compatibility.
Token Standards on Tezos
In Tezos, token standards are written in the Tezos Interoperability Proposal (TZIP) format.
- FA1.2(Approvable Ledger): The FA1.2 token standard on Tezos is inspired by the ERC-20 standard on Ethereum. It provides a basic framework for creating fungible tokens on the Tezos blockchain. Fungible tokens are interchangeable units that have the same value, meaning one token is equivalent to any other token of the same type.
The FA1.2 standard specifies a set of functions that enable token transfers, balance inquiries, and approvals. It allows token holders to transfer tokens between addresses, check their token balances, and approve other addresses to spend tokens on their behalf. This functionality facilitates basic token management and enables integration with decentralized exchanges (DEXs) and other applications that rely on fungible tokens.
- FA2(Multi-Asset Interface): The FA2 token standard is an upgraded and more versatile standard for fungible tokens on Tezos. It provides enhanced functionality compared to FA1.2 and allows for the creation of multiple token types within a single smart contract.
FA2 introduces the concept of token operators, which are addresses authorized by token owners to manage their tokens. Token operators can perform transfers on behalf of the token owners, which enables more complex scenarios such as batch transfers and the creation of token pools. FA2 also provides improved mechanisms for token approvals, allowing more granular control over token allowances.
The flexibility of FA2 allows for the creation of token ecosystems with different types of fungible assets, each with its unique properties and behaviours. This makes FA2 suitable for applications that require more sophisticated token management, such as decentralized finance (DeFi) platforms and tokenized asset marketplaces.
- Non-Fungible Tokens (NFTs): Tezos supports the creation and management of non-fungible tokens (NFTs), which represent unique digital assets. NFTs have distinct properties and cannot be exchanged on a one-to-one basis like fungible tokens. Each NFT has a specific identifier, and its ownership can be transferred between addresses.
Developers can implement NFT functionality on Tezos using standards like FA2 or by creating custom smart contracts tailored to their specific NFT requirements. NFTs on Tezos can represent various digital assets, such as artwork, collectables, virtual real estate, or in-game items. The ownership and transaction history of NFTs is recorded on the Tezos blockchain, providing transparency and immutability.
- Wrapped Tokens: Wrapped tokens on Tezos bridge the value and liquidity of assets from other blockchains, primarily Ethereum, onto the Tezos blockchain. Wrapped tokens are created by locking the original assets (e.g., ETH or ERC-20 tokens) on the source blockchain and issuing an equivalent representation on Tezos.
Wrapped tokens enable users to interact with assets from other blockchains within the Tezos ecosystem. For example, a wrapped Bitcoin (wBTCZ) represents Bitcoin on Tezos, allowing users to trade or use Bitcoin in Tezos DeFi applications. The value of wrapped tokens is pegged to the value of the underlying asset on the source blockchain, maintained through a trusted custodian or decentralized mechanisms.
Wrapped tokens provide increased interoperability between blockchain ecosystems, allowing users to access and utilize assets from different networks without needing to move the underlying assets across blockchains.
