What is Tezos Blockchain? A Comprehensive Guide to the Self-Upgradable Blockchain

Tezos is an open-source, self-upgradable blockchain platform designed to host decentralized applications (dApps) and digital assets. It differentiates itself from other blockchain networks through its unique self-amendment feature, which allows it to upgrade without requiring hard forks.

Governed by its stakeholders, Tezos facilitates seamless protocol upgrades, enhancing its adaptability, security, and long-term sustainability.

Key Features of Tezos

1. Self-Amendment

One of Tezos' standout features is self-amendment, which enables protocol upgrades without splitting the blockchain.

This eliminates community divisions, reduces coordination costs, and ensures smooth transitions to newer versions of the protocol. By integrating upgrades within its governance model, Tezos maintains network stability while fostering innovation.

2. On-Chain Governance

Tezos employs a formal on-chain governance mechanism where all stakeholders can participate in decision-making. Through a structured election cycle, stakeholders vote on proposed protocol amendments, ensuring democratic and systematic network upgrades.

This governance model reduces reliance on external interventions and allows Tezos to evolve efficiently.

3. Decentralized Innovation

The Tezos protocol includes a funding mechanism that allows stakeholders to reward developers and contributors who enhance the network.

This decentralized model incentivizes participation and nurtures a diverse ecosystem of developers, ensuring continuous improvement and adoption.

4. Smart Contracts & Formal Verification

Tezos supports smart contracts and dApps that cannot be censored or shut down by third parties.

Additionally, it facilitates formal verification, a mathematical approach to validating code correctness, which enhances security and reduces the risk of bugs that could lead to exploits or financial loss.

5. Proof-of-Stake (PoS) Consensus Mechanism

Unlike energy-intensive Proof-of-Work (PoW) models, Tezos utilizes a Proof-of-Stake (PoS) consensus mechanism, which allows stakeholders to validate transactions and secure the network.

This model is more cost-effective and environmentally friendly, reducing barriers to entry for participants.

6. Delegation Mechanism

Tezos' PoS model allows users to delegate their staking rights to others without transferring ownership of their assets.

This provides flexibility for users who do not wish to participate directly in the consensus process while still earning staking rewards.

Tezos Token (XTZ) and Its Use Cases

Tezos' native token, Tez (XTZ), powers the network and has various use cases, including:

1. Governance Participation: Token holders vote on protocol changes and governance decisions.

2. Staking (Baking): Users can stake XTZ to earn rewards and contribute to network security.

3. Transaction Fees: XTZ is used to pay transaction fees on the network.

4. Asset Tokenization: Companies utilize Tezos to tokenize financial instruments and real-world assets.

5. Decentralized Finance (DeFi) and NFTs: Tezos supports DeFi applications and NFT projects, offering an energy-efficient alternative to Ethereum.

The History of Tezos

Tezos was conceived by Arthur Breitman, a former Google X and Waymo engineer, alongside his wife Kathleen Breitman. Arthur published a white paper in 2014 outlining Tezos' principles.

The project gained traction in 2017 when the Switzerland-based Tezos Foundation, led by Johann Gevers, launched an Initial Coin Offering (ICO), raising $232 million in just 13 days.

However, internal disputes between the Breitmans and Gevers delayed the launch. The situation was eventually resolved in 2018, allowing Tezos to go live.

Over the years, the network has overcome legal challenges and management issues, solidifying its position as a leading blockchain platform.

How Tezos Works

Tezos' blockchain consists of two primary components:

1. Network Shell: Manages transactions, administrative operations, and self-amendments based on user votes.

2. Network Protocol: Sends upgrade proposals to the shell for review and implementation.

Tezos operates on a Liquid Proof-of-Stake (LPoS) consensus mechanism, where users can either bake (stake) XTZ tokens or delegate them to bakers. Bakers validate transactions and vote on protocol changes, ensuring decentralization and security.

Governance and Voting Process

Tezos' governance involves a four-phase voting cycle, each lasting 23 days:

1. Proposal Period: Any baker can propose network changes.

2. Exploration Vote Period: Proposals receiving at least 80% approval move forward.

3. Testing Period: The proposal is deployed on a temporary fork to assess functionality.

Promotion Vote Period: If the final vote exceeds 80%, the proposal is implemented into the main protocol.

Security and Decentralization

Tezos' decentralized architecture eliminates single points of failure. Its consensus mechanism ensures that amendments require stakeholder consensus, making unauthorized changes nearly impossible.

The network employs cryptographic encryption and formal verification to enhance security and prevent smart contract vulnerabilities.

Adoption and Use Cases

Tezos has attracted significant interest in various industries:

1. Finance: Banks and financial institutions explore Tezos for tokenizing assets.

2. Central Bank Digital Currencies (CBDCs): European central banks have tested Tezos for digital euro feasibility.

3. NFT Market: Tezos has become a preferred blockchain for eco-friendly NFT projects.

4. DeFi Platforms: Several DeFi applications run on Tezos, leveraging its efficient PoS model.

Future Prospects

Tezos' unique governance structure, adaptability, and energy-efficient consensus model position it as a strong competitor in the blockchain space.

Its ability to upgrade seamlessly without forking provides long-term stability, attracting developers, enterprises, and investors.
