Tezos (XTZ) is a third-generation blockchain platform designed for smart contracts and decentralized applications (dApps). It aims to improve upon earlier blockchain systems through a self-amending ledger and on-chain governance. However, the project has faced significant challenges, including internal conflicts and delays.
The Ambitious Beginning of Tezos
Founded by Arthur and Kathleen Breitman, the Tezos project began development in 2014. Its initial coin offering (ICO) launched in July 2017 and quickly became one of the largest in history. Within just two weeks, the uncapped sale raised approximately $232 million worth of Bitcoin and Ethereum. This made it the second-largest public token sale at the time, trailing only behind Filecoin.
Governance Challenges and Internal Conflicts
Shortly after the ICO, serious disputes emerged regarding control over the Tezos project. These conflicts caused multiple delays in the network’s launch and led to legal challenges.
The Breitmans established a Swiss-based foundation to manage the ICO funds. However, tensions arose between the foundation’s president, Johann Gevers, and the founders. Allegations of self-dealing and conflicts of interest surfaced, leading to a prolonged internal struggle.
This conflict resulted in several class-action lawsuits from contributors who claimed Tezos had conducted an unregistered securities sale. The situation was eventually resolved in February 2018 when all three foundation board members were replaced. To restore trust, the foundation brought in PwC to conduct external audits of its operations.
After months of delays, Tezos launched its beta mainnet in June 2018, with the full mainnet following in the third quarter of that year.
Tezos' Technological Innovations
Tezos positions itself as an improvement over earlier blockchain platforms like Bitcoin and Ethereum through several key features.
Self-Amending Ledger
Unlike traditional blockchains that require hard forks for protocol upgrades, Tezos enables seamless evolution through its self-amending capability. This approach aims to prevent community splits that often accompany contentious hard forks.
On-Chain Governance
XTZ holders can participate in governing the protocol through a built-in voting mechanism. This system allows stakeholders to approve or reject proposed protocol upgrades. Developers can submit upgrade proposals that include compensation requests for their work, creating an incentive structure for ongoing development.
This governance model resembles Dash's system but with enhanced capabilities for formal verification and smart contract functionality.
Smart Contracts and Formal Verification
Tezos supports smart contracts through its Michelson programming language. Unlike Ethereum's Solidity, Michelson is a functional language designed specifically for Tezos that facilitates formal verification.
Formal verification allows developers to mathematically prove the correctness of their smart contract code, helping to ensure certain properties will be maintained. While not guaranteeing 100% error-free code, this approach significantly enhances security and reliability.
Delegated Proof-of-Stake Consensus
Tezos uses a Delegated Proof-of-Stake (DPoS) consensus mechanism. Token holders can "bake" (similar to staking) by depositing XTZ to participate in block validation. Those who don't wish to participate directly can delegate their voting rights to other users called "bakers."
This system aims to achieve network security while maintaining decentralization and energy efficiency compared to proof-of-work systems.
Competitive Landscape and Challenges
Tezos enters a crowded field of smart contract platforms, competing with established players like Ethereum and newer projects like Cardano and EOS. While all these platforms aim to improve upon earlier blockchain technology, Ethereum maintains a significant lead in adoption and real-world usage.
The Tezos team faces the challenge of demonstrating that their technology can actually solve the scalability and governance issues that plague existing platforms. As of its launch, the project had yet to prove it could deliver on its ambitious promises at scale.
Market Performance and Token Distribution
ICO contributors waited approximately one year to receive their XTZ tokens, creating significant pent-up selling pressure when tokens finally became available. This led to substantial price volatility immediately after listing on exchanges.
Some exchanges offered XTZ IOUs (I Owe You) during the development phase, allowing speculative trading before the actual token launch. These IOUs reached nearly $12 in December 2017 but declined significantly before the mainnet launch.

Lessons from the Tezos Journey
The Tezos story offers several important lessons for cryptocurrency investors and enthusiasts:
- Market sentiment often outweighs fundamentals - The project raised substantial funds based largely on hype rather than demonstrated technology
- Due diligence is crucial - Many investors failed to properly evaluate Tezos' core value proposition and differentiation
- Governance structures matter - Even well-designed systems can face implementation challenges
- Execution is everything - Promises and whitepapers mean little without successful implementation
The project demonstrates that innovative technology alone cannot guarantee success. Effective execution, community trust, and responsive governance are equally important factors in blockchain project development.
Frequently Asked Questions
What makes Tezos different from Ethereum?
Tezos uses a self-amending ledger that enables protocol upgrades without hard forks. It also features formal verification for smart contracts and an on-chain governance system that allows token holders to vote on proposed changes.
How does Tezos governance work?
XTZ holders can vote on protocol upgrade proposals submitted by developers. This includes decisions about technical improvements and compensation for development work. Users can either vote directly or delegate their voting rights to others.
What is Tezos baking?
Baking is Tezos' equivalent of staking. Users can lock up XTZ tokens to participate in block validation and earn rewards. Those who don't want to run their own infrastructure can delegate tokens to professional bakers.
Is Tezos a good investment?
Like all cryptocurrencies, Tezos carries significant risk. While the technology is innovative, the project faces strong competition and must still prove its value proposition at scale. Investors should conduct thorough research before committing funds.
What was the main cause of Tezos' delays?
Internal conflicts between the foundation board and project creators caused most delays. Disputes over fund control and governance stalled development for several months before being resolved.
How does formal verification improve smart contract security?
Formal verification allows developers to mathematically prove that their code behaves as intended. This helps prevent common vulnerabilities and ensures certain properties are maintained, though it doesn't eliminate all possible bugs.
Conclusion
Tezos represents an ambitious attempt to create a self-improving blockchain platform with sophisticated governance mechanisms. While the technology shows promise, the project has faced significant challenges in implementation and community trust-building.
The crypto space continues to evolve rapidly, with multiple platforms competing for developer mindshare and user adoption. Tezos must demonstrate tangible advantages over established competitors to succeed long-term. As with any emerging technology, actual implementation and adoption will ultimately determine success more than technological promises alone.
The journey of Tezos highlights the importance of both technological innovation and effective project governance in the blockchain space.
