According to development update shared on 11th June 2021, the first smart contract on Cardano has been run successfully on Alonzo testnet.
As earlier reported by Herald Sheets, the official implementation of smart contracts functionality on Cardano is expected to play out by September, after Alonzo hard fork.
At the moment, Cardano’s team of developers is in the Alonzo Blue phase. In this phase, the team’s focus is centered on developing the command-line interface (CLI) for writing the “Hello World” style of smart contracts.
The development is expected to transition to Alonzo White once partners and pioneers are able to create basic scripts.
According to IOHK’s head of delivery and projects, Nigel Hemsley, partners and pioneers have to successfully prove that they can submit, validate, and execute on-chain. There will be an introduction of all Plutus components, such as the application backend in this stage.
Altlabs, Eleks, Mlabs, Obsidian, and other partners are currently working on such use cases as a token swap, liquidity and stake pools, non-fungible tokens (NFTs), and an exchange.
The testnet will go public during the “Alonzo Purple” phase when all stake pool operators and Plutus pioneers will be able to participate.
