Method Detail

isDifficultyTransitionPoint

protected boolean isDifficultyTransitionPoint(StoredBlock storedPrev)

Checks if we are at a difficulty transition point.

Parameters:

storedPrev - The previous stored block

Returns:

If this is a difficulty transition point

checkDifficultyTransitions

public void checkDifficultyTransitions(StoredBlock storedPrev,
                                       Block nextBlock,
                                       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

Throws:

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

BlockStoreException

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 (i.e. the main coin issue for Dogecoin).

Specified by:

getMaxMoney in class NetworkParameters

getMinNonDustOutput

public Coin getMinNonDustOutput()

Description copied from class: NetworkParameters

Any standard (ie pay-to-address) output smaller than this value will most likely be rejected by the network.

Specified by:

getMinNonDustOutput in class NetworkParameters

getMonetaryFormat

public MonetaryFormat getMonetaryFormat()

Description copied from class: NetworkParameters

The monetary object for this currency.

Specified by:

getMonetaryFormat in class NetworkParameters

getProtocolVersionNum

public int getProtocolVersionNum(NetworkParameters.ProtocolVersion version)

Specified by:

getProtocolVersionNum in class NetworkParameters

getSerializer

public BitcoinSerializer getSerializer(boolean parseRetain)

Description copied from class: NetworkParameters

Construct and return a custom serializer.

Specified by:

getSerializer in class NetworkParameters

getUriScheme

public String getUriScheme()

Description copied from class: NetworkParameters

Scheme part for URIs, for example "bitcoin".

Specified by:

getUriScheme in class NetworkParameters

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 overriden for other networks.

Specified by:

hasMaxMoney in class NetworkParameters
