Cardano completed its long-awaited Shelley hard fork today, transitioning its blockchain from a federated network managed primarily by the Cardano Foundation to a community-run protocol. The new Shelley mainnet introduces Cardano’s proposed Proof-of-Stake (PoS) layer, which allows users to contribute to the transaction validation process either directly (by operating a stake pool) or indirectly (via delegation) in exchange for staking rewards. The first rewards distribution will occur on Aug. 18.
Shelley is just the second step in a series of upgrades first proposed by the project. The next phase, called Goguen, will introduce smart contract functionality. Lead Cardano developer IOHK anticipates launching Goguen before the end of the year. Subsequent upgrades Voltaire and Basho intend to unlock the project’s proposed on-chain governance system and Hydra scaling system, respectively.
