What it is
Tezos is a self-amending proof-of-stake blockchain (2014, L.M. Goodman) designed so stakeholders can upgrade the protocol itself onchain without hard forks, and it supports Turing-complete smart contracts.
Technology & consensus
The network shell is protocol-agnostic while stakeholders amend the protocol through quarterly election cycles (proposal, exploration, testing, promotion votes requiring supermajority and dynamic quorum). Consensus is pure proof-of-stake: block producers and endorsers are randomly selected via a follow-the-coin procedure, post security bonds that are forfeited on double-signing, and earn rewards. It was implemented in OCaml for formal verification.
Token utility
XTZ (tez) pays transaction and storage fees, is bonded as collateral by bakers/validators to secure the network, and grants governance rights to vote on protocol amendments and delegate stake.
Key risks & notes
The 2014 whitepaper predates many amendments, so its specifics (rewards, cycles) are outdated. XTZ has staking-driven inflation that dilutes non-stakers. Competes with Ethereum L2s and newer L1s for developers and TVL, and onchain governance can concentrate among large bakers.
