Proof of work consensus for Tetcore.
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
A build of mining, containing the metadata and the block proposal.
Mining metadata. This is the information needed to start an actual mining loop.
Mining worker that exposes structs to query the current mining build and submit mined blocks.
Auxiliary storage data for PoW.
A block importer for PoW.
Intermediate value passed to block importer.
A verifier for PoW blocks.
Auxiliary storage prefix for PoW engine.
Intermediate key for PoW engine.
Algorithm used for proof of work.
Import queue for PoW engine.
Register the PoW inherent data provider, if not registered already.
Start the mining worker for PoW. This function provides the necessary helper functions that can be used to implement a miner. However, it does not do the CPU-intensive mining itself.
The PoW import queue type.
