* Ensure we spawn the block import worker as an essential task This pr ensures that we spawn the block import worker as an essential task. This is quite important as we need to bring down the node when the block import is done. Besides that it adds some debug output to the block import worker. * Don't be stupid :D
Proof of work consensus for Substrate.
To use this engine, you can need to have a struct that implements
PowAlgorithm. After that, pass an instance of the struct, along
with other necessary client references to import_queue to setup
the queue. Use the start_mine function for basic CPU mining.
The auxiliary storage for PoW engine only stores the total difficulty.
For other storage requirements for particular PoW algorithm (such as
the actual difficulty for each particular blocks), you can take a client
reference in your PowAlgorithm implementation, and use a separate prefix
for the auxiliary storage. It is also possible to just use the runtime
as the storage, but it is not recommended as it won't work well with light
clients.
