Tezos is a self-amending blockchain — it can upgrade itself through on-chain governance without hard forks. This unique feature lets Tezos evolve continuously while avoiding the contentious splits that plagued Bitcoin and Ethereum.
History
Tezos was conceived by Arthur and Kathleen Breitman in 2014 with a deliberately different design philosophy: instead of relying on hard forks to evolve, the protocol would upgrade itself on-chain via governance. The 2017 ICO raised $232M in 14 days — at the time one of the largest crypto fundraises ever. A legal and operational dispute between the founders and the Tezos Foundation delayed mainnet, which finally launched in June 2018.
Since launch, Tezos has shipped 15+ self-amending upgrades on schedule (named after Greek cities — Athens, Babylon, Granada, Hangzhou, Jakarta, Kathmandu, Lima, Mumbai, Nairobi, Oxford, Paris). No other major L1 has matched this cadence of on-chain governance upgrades without a contentious fork.
How Tezos Works
- Liquid Proof-of-Stake (LPoS): Token holders either run a “baker” node (3,000+ XTZ required) or delegate their stake to one — delegation is free, non-custodial, and there is no lock-up
- On-chain governance: Bakers vote in five phases on every protocol amendment. Approved changes activate automatically with no fork — node operators simply upgrade or are left on the old chain
- Formal verification: Tezos’ Michelson smart-contract language is designed for mathematical proof-of-correctness, which is why institutions building tokenized securities have favored it
- Etherlink (L2): Tezos now has an EVM-compatible Optimistic Rollup layer-2 launched in 2024, bringing Ethereum tooling to Tezos settlement
Tokenomics
XTZ: No hard cap — inflationary at ~4.5%/year, paid as staking rewards. Adaptive issuance (Paris upgrade, 2024) now adjusts inflation between 0.25% and 10% based on staking participation, targeting roughly 50% of supply staked.
Utility:
- Staking (“baking”): ~5–6% APY for delegators, slightly higher for bakers
- Gas: Pay for transactions and smart-contract execution
- Governance: Bakers vote on protocol amendments proportional to stake

Use Cases
- RWA & security tokens: Société Générale issued euro stablecoin EURCV on Tezos; multiple regulated security-token issuers chose Tezos for its formal verification
- NFTs: Objkt and fxhash made Tezos a leading home for generative art (low fees, eco-friendly PoS narrative)
- CBDC pilots: Banque de France used Tezos in CBDC experiments
- Gaming: Ubisoft Quartz launched on Tezos; further pushes via Etherlink
Pros and Cons
- Pro: Proven on-chain governance — 15+ upgrades without a contentious fork
- Pro: Formal verification makes it appealing for regulated finance
- Pro: No lock-up staking, ~5–6% APY
- Pro: Etherlink brings EVM compatibility while keeping Tezos settlement
- Con: Smaller dev ecosystem than Ethereum, Solana, or Cosmos
- Con: Inflationary supply (no hard cap)
- Con: Mindshare has dropped since the 2021 NFT cycle
Frequently Asked Questions
What makes Tezos different from other Layer 1 blockchains?
Tezos’ core differentiator is self-amendment. Every other major L1 evolves via hard forks (sometimes contentious — see Bitcoin Cash, Ethereum Classic). Tezos votes on protocol changes on-chain and applies them automatically. That’s why it has shipped 15+ protocol upgrades without ever splitting the chain. The trade-off is slower iteration than monolithic chains where a core team can ship instantly.
Is XTZ a good investment?
XTZ is a long-cycle bet on formal-verification + on-chain governance being the right model for institutional and regulated use cases (security tokens, CBDCs, tokenized assets). It has missed retail narratives since 2021 and underperformed faster L1s on traders’ minds. The Etherlink L2 and adaptive issuance upgrade are the major recent catalysts. See altcoin guide for portfolio framing.
How do I stake Tezos?
Easiest path: hold XTZ in any wallet supporting Tezos (Temple, Kukai, Trust Wallet, Ledger) and delegate to a baker. Delegation is free, non-custodial, and there is no lock-up — your XTZ stays in your wallet. Rewards arrive every ~3 days. Expect 5–6% APY. See our staking guide.
What is Etherlink?
Etherlink is Tezos’ EVM-compatible Layer-2, launched in 2024. It lets Ethereum developers deploy unchanged Solidity contracts while settling to Tezos and paying gas in XTZ. The goal is to bridge Tezos’ settlement guarantees with Ethereum’s much larger developer ecosystem.
