Crate tc_consensus_pow[−][src]
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
clients.
Structs
MiningBuild | A build of mining, containing the metadata and the block proposal. |
MiningMetadata | Mining metadata. This is the information needed to start an actual mining loop. |
MiningWorker | Mining worker that exposes structs to query the current mining build and submit mined blocks. |
PowAux | Auxiliary storage data for PoW. |
PowBlockImport | A block importer for PoW. |
PowIntermediate | Intermediate value passed to block importer. |
PowVerifier | A verifier for PoW blocks. |
Enums
Error |
Constants
POW_AUX_PREFIX | Auxiliary storage prefix for PoW engine. |
Statics
INTERMEDIATE_KEY | Intermediate key for PoW engine. |
Traits
PowAlgorithm | Algorithm used for proof of work. |
Functions
import_queue | Import queue for PoW engine. |
register_pow_inherent_data_provider | Register the PoW inherent data provider, if not registered already. |
start_mining_worker | 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. |
Type Definitions
PowImportQueue | The PoW import queue type. |
