From what I'm seeing, this is the first time that this is being done. A blockchain platform will allow public and private applications to interoperate. AVA may have the potential to become the global issuance platform for all digital assets, and this is possible only because of its unique architectural model. They're
releasing their codebase to the public and wanted to provide an advanced infrastructure for building decentralized finance (DeFi) applications, enabling anyone to launch their own blockchains with custom validators and issue assets under any required features and rulesets, including custom virtual machines and programmable legal compliance.
Can people use this effectively, and can companies benefit from this feature?
