Method Details

getPaymentProtocolId

public String getPaymentProtocolId()

Specified by:

getPaymentProtocolId in class NetworkParameters

Returns:

the payment protocol network id string

checkDifficultyTransitions

public void checkDifficultyTransitions(StoredBlock storedPrev,
 Block next,
 BlockStore blockStore)
                                throws VerificationException,
BlockStoreException

Description copied from class: NetworkParameters

Throws an exception if the block's difficulty is not correct.

Specified by:

checkDifficultyTransitions in class NetworkParameters

Parameters:

storedPrev - previous stored block

next - proposed block

blockStore - active BlockStore

Throws:

VerificationException - if the block's difficulty is not correct.

BlockStoreException - if an error occurred accessing the BlockStore

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

getMaxMoney

public Coin getMaxMoney()

Description copied from class: NetworkParameters

Returns the number of coins that will be produced in total, on this network. Where not applicable, a very large number of coins is returned instead (e.g. the main coin issue for Dogecoin).

Specified by:

getMaxMoney in class NetworkParameters

Returns:

maximum number of coins for this network

getMonetaryFormat

public MonetaryFormat getMonetaryFormat()

Description copied from class: NetworkParameters

The monetary object for this currency.

Specified by:

getMonetaryFormat in class NetworkParameters

Returns:

formatting utility object

getUriScheme

public String getUriScheme()

Description copied from class: NetworkParameters

Scheme part for URIs, for example "bitcoin".

Specified by:

getUriScheme in class NetworkParameters

Returns:

a string with the "scheme" part

hasMaxMoney

public boolean hasMaxMoney()

Description copied from class: NetworkParameters

Returns whether this network has a maximum number of coins (finite supply) or not. Always returns true for Bitcoin, but exists to be overridden for other networks.

Specified by:

hasMaxMoney in class NetworkParameters

Returns:

true if network has a fixed maximum number of coins

getSerializer

public BitcoinSerializer getSerializer()

Description copied from class: NetworkParameters

Construct and return a custom serializer.

Specified by:

getSerializer in class NetworkParameters

Returns:

the serializer
