In a tweet this Tuesday, Input Output Hong Kong (IOHK), a leading developer of Cardano blockchain, announced the launch of the long-awaited new version of blockchain nodes, Alonzo Blue 2.0. However, the latest version is only available on testnet, with the mainnet expected to launch in the coming weeks.

As the Cardano development team continues its journey to a fully executable smart contract platform, Alonzo Blue 2.0 marks the latest milestone in the road to full launch. Defining it as “an important milestone,” the Alonzo Blue 2.0 update includes an update of the Command Line Interface (CLI) – a crucial building block of the Cardano blockchain.
While the code is still in the test phase, it will provide users with a foundation to build smart contract properties on Cardano, which is expected to allow various smart contract applications such as decentralized finance (DeFi) applications.
Additionally, Alonzo Blue 2.0 will allow users to associate a transaction's meta-data on-chain and store executable contract data. With the update, stake pool operators, or SPOs, will be able to start testing and sending simple, smart contract transactions to the blockchain ledger, opening up a new smart contract era on Cardano.
At the announcement, SPOs were given 24 hours (only a few left) to complete updating their nodes to Alonzo Blue. This will allow them to run their first test scripts later today.
