Tezos

Tezos is a self-amending blockchain platform that upgrades itself through on-chain governance, eliminating the need for hard forks that have historically split crypto communities. Founded by Arthur and Kathleen Breitman and launched in 2018 after one of the largest ICOs in history (raising $232 million in 2017), Tezos was designed to address the governance challenges that plagued earlier blockchains. The platform's key innovation is its ability to formally propose, vote on, and implement protocol upgrades entirely on-chain — a process that has successfully executed over a dozen major upgrades without any contentious forks.

Tezos uses Liquid Proof of Stake (LPoS), where token holders called 'bakers' validate transactions and produce blocks. Unlike traditional delegated Proof of Stake systems, Tezos allows any token holder to become a baker if they hold the minimum required stake (currently 6,000 XTZ), or they can delegate their tokens to existing bakers without transferring custody. This creates a flexible staking model that balances accessibility with decentralization. Bakers participate in governance by voting on protocol amendment proposals through a multi-phase process: proposal, exploration, testing, and promotion.

Tezos has distinguished itself through its emphasis on formal verification — a mathematical technique for proving the correctness of smart contract code. This makes Tezos particularly attractive for high-value applications in finance, real estate, and digital securities where contract bugs can have catastrophic consequences. The platform has found significant adoption in the art and culture space (powering major NFT platforms like fxhash and objkt), institutional tokenization, and has been adopted by multiple central banks for CBDC pilot programs. By 2026, Tezos has undergone numerous seamless protocol upgrades that have added features like smart rollups for scalability, timelocks for commit-reveal schemes, and data availability improvements — all without splitting the chain.
