Tezos is a self-amending blockchain network which incorporates a formal, on-chain mechanism for proposing, selecting, testing, and activating protocol upgrades without the need to hard fork. Operates under liquid PoS consensus.

Objects of governance & Used mechanics

Upgrades to the protocol through proposal & voting process. Uses min quorum adapted to the average participation and and 80% of supermajority support level to pass.

  • Developers independently submit proposals for protocol upgrades and request for compensation for their work.

  • The request for compensation makes sure that the developers have a strong economic incentive to contribute to the ecosystem

  • The proposal goes through a testing period wherein the community tests the protocol and criticizes it for possible improvements.

  • After repeated testing, the Tezos token holders can then vote on whether the proposal should be approved or not.

  • Once a legitimate upgrade is decided on, a “hot swap” occurs on the protocol, which initiates the new version of the protocol.
