Tezos’ Evolution: A Journey Through 18 Cities and Their Impact on Blockchain

Tezos has undergone a transformative journey across 18 cities, each contributing to its evolution into a fast, secure, and adaptable blockchain network. The tour, documented by Tezzard #1650, underscores the protocol upgrades that have shaped its dynamic governance and technical capabilities.

The journey began in Athens in May 2019, with an upgrade that raised the gas limit per block and reduced validator roll size, laying the groundwork for on-chain governance. Babylon followed in October 2019, introducing the Emmy+ consensus algorithm to streamline network operations and smart contract development.

Carthage arrived in March 2020, boosting gas limits and refining reward formulas for fairness. Delphi, in September 2020, optimized gas and storage costs, making transactions more economical. Edo's February 2021 upgrade brought privacy-preserving smart contracts and amendments to the governance process.

Florence, in May 2021, doubled the maximum operation size, further enhancing scalability. Each upgrade reflects Tezos' commitment to innovation, driven by a decentralized community of developers and validators.
