CheckpointData()

const CCheckpointData& CheckpointData

(

const std::string &

chain

)

Definition at line 137 of file checkpoints.cpp.

Here is the caller graph for this function:

CreateChainParams()

std::unique_ptr<CChainParams> CreateChainParams

(

const std::string &

chain

)

Creates and returns a std::unique_ptr<CChainParams> of the chosen chain.

Returns

a CChainParams* of the chosen chain.

Exceptions

a	std::runtime_error if the chain is not supported.

Definition at line 499 of file chainparams.cpp.

Here is the caller graph for this function:

CreateGenesisBlock()

CBlock CreateGenesisBlock	(	uint32_t	nTime,
		uint32_t	nNonce,
		uint32_t	nBits,
		int32_t	nVersion,
		const Amount	genesisReward
	)

Build the genesis block.

Note that the output of its generation transaction cannot be spent since it did not originally exist in the database.
