/**
|
|
* The idea here is that this will implement the IBlockchain interface.
|
|
* But, it will allow the dev to specify multiple child IBlockchain interfaces for configuration.
|
|
* So, if the network is not available, it can fallback to the local and sync later.
|
|
*
|
|
* @example
|
|
* ```ts
|
|
* // Actual interface will be more complex, but this is the rough idea.
|
|
* const blockchain = new Blockchain([
|
|
* new BlockchainLocal(...),
|
|
* new BlockchainElectrum(...)
|
|
* ])
|
|
* ```
