Method Detail

allowEmptyPeerChain

public boolean allowEmptyPeerChain()

Description copied from class: NetworkParameters

If we are running in testnet-in-a-box mode, we allow connections to nodes with 0 non-genesis blocks.

Overrides:

allowEmptyPeerChain in class NetworkParameters

Returns:

true if allowed

get

public static RegTestParams get()

getGenesisBlock

public Block getGenesisBlock()

Description copied from class: NetworkParameters

Genesis block for this chain.

The first block in every chain is a well known constant shared between all Bitcoin implementations. For a block to be valid, it must be eventually possible to work backwards to the genesis block by following the prevBlockHash pointers in the block headers.

The genesis blocks for both test and main networks contain the timestamp of when they were created, and a message in the coinbase transaction. It says, "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks".

Specified by:

getGenesisBlock in class NetworkParameters

Returns:

genesis block
