Cardano plans to launch the Alonzo hard fork on the mainnet on September 12
IOHK marketing and communications director Tim Harrison announced that Cardano's goal is to launch the Alonzo hard fork on the mainnet on September 12. The upgrade will allow users to run smart contracts on this PoS blockchain.
Cardano delivery lead Nigel Hemsley claimed that the project’s engineering and testing teams are working “extremely hard” as they move quickly towards the hard fork combiner event. At the same time, a number of partners are developing decentralized applications written in the Plutus programming language. By the end of the "Purple phase," Cardano will have around 500 community members working on the network, Hemsley said.
NEAR Protocol and Filecoin jointly launched a $300,000 joint grant program to encourage funding applications for any project that supports the integration of Filecoin and NEAR, and all eligible projects will receive financial support for further development.
