blockchain-core frontend bundle

Source AsyncComponent

The blockchain-core frontend bundle is similar to the blockchain-core runtime and its build to handle several UI steps including blockchain-core instance without account interactions, blockchain-core instance including account id for profile interactions and blockchain-core instance to interact with business centers. It exposes the following Runtime parameters and several functions to create, handle and overwrite them:
