Member Function Documentation

checkBlock()

virtual bool interfaces::Mining::checkBlock ( const CBlock &  block, const node::BlockCheckOptions &  options, std::string &  reason, std::string &  debug  )

pure virtual

Checks if a given block is valid.

Parameters

[in]	block	the block to check
[in]	options	verification options: the proof-of-work check can be skipped in order to verify a template generated by external software.
[out]	reason	failure reason (BIP22)
[out]	debug	more detailed rejection reason

Returns

whether the block is valid

For signets the challenge verification is skipped when check_pow is false.

context()

virtual node::NodeContext * interfaces::Mining::context ( )

inlinevirtual

Get internal node context.

Useful for RPC and testing, but not accessible across processes.

Definition at line 159 of file mining.h.

createNewBlock()

virtual std::unique_ptr< BlockTemplate > interfaces::Mining::createNewBlock ( const node::BlockCreateOptions &  options = {}, bool  cooldown = true  )

pure virtual

Construct a new block template.

Parameters

[in]	options	options for creating the block
[in]	cooldown	wait for tip to be connected and IBD to complete. If the best header is ahead of the tip, wait for the tip to catch up. It's recommended to disable this on regtest and signets with only one miner, as these could stall.

Return values

BlockTemplate	a block template.
std::nullptr	if the node is shut down or interrupt() is called.

Here is the caller graph for this function:

getTip()

virtual std::optional< BlockRef > interfaces::Mining::getTip ( )

pure virtual

Returns the hash and height for the tip of this chain.

Here is the caller graph for this function:

interrupt()

virtual void interfaces::Mining::interrupt ( )

pure virtual

Interrupts createNewBlock and waitTipChanged.

isInitialBlockDownload()

virtual bool interfaces::Mining::isInitialBlockDownload ( )

pure virtual

Returns whether IBD is still in progress.

Here is the caller graph for this function:

isTestChain()

virtual bool interfaces::Mining::isTestChain ( )

pure virtual

If this chain is exclusively used for testing.

Here is the caller graph for this function:

waitTipChanged()

virtual std::optional< BlockRef > interfaces::Mining::waitTipChanged ( uint256  current_tip, MillisecondsDouble  timeout = MillisecondsDouble::max()  )

pure virtual

Waits for the connected tip to change.

During node initialization, this will wait until the tip is connected (regardless of timeout).

Parameters

[in]	current_tip	block hash of the current chain tip. Function waits for the chain tip to differ from this.
[in]	timeout	how long to wait for a new tip (default is forever)

Return values

BlockRef	hash and height of the current chain tip after this call.
std::nullopt	if the node is shut down or interrupt() is called.

Here is the caller graph for this function:
