Class KeyChainGroup.Builder

    • Method Detail

      • fromRandom

        public KeyChainGroup.Builder fromRandom​(ScriptType outputScriptType)

        Add chain from a random source.

        In the case of P2PKH, just a P2PKH chain is created and activated which is then the default chain for fresh addresses. It can be upgraded to P2WPKH later.

        In the case of P2WPKH, both a P2PKH and a P2WPKH chain are created and activated, the latter being the default chain. This behaviour will likely be changed in future such that only a P2WPKH chain is created and activated.

        Parameters:
        outputScriptType - type of addresses (aka output scripts) to generate for receiving
      • fromSeed

        public KeyChainGroup.Builder fromSeed​(DeterministicSeed seed,
                                              ScriptType outputScriptType)

        Add chain from a given seed.

        In the case of P2PKH, just a P2PKH chain is created and activated which is then the default chain for fresh addresses. It can be upgraded to P2WPKH later.

        In the case of P2WPKH, both a P2PKH and a P2WPKH chain are created and activated, the latter being the default chain. This behaviour will likely be changed in future such that only a P2WPKH chain is created and activated.

        Parameters:
        seed - deterministic seed to derive all keys from
        outputScriptType - type of addresses (aka output scripts) to generate for receiving
      • fromKey

        public KeyChainGroup.Builder fromKey​(DeterministicKey accountKey,
                                             ScriptType outputScriptType)

        Add chain from a given account key.

        In the case of P2PKH, just a P2PKH chain is created and activated which is then the default chain for fresh addresses. It can be upgraded to P2WPKH later.

        In the case of P2WPKH, both a P2PKH and a P2WPKH chain are created and activated, the latter being the default chain. This behaviour will likely be changed with bitcoinj 0.16 such that only a P2WPKH chain is created and activated.

        Parameters:
        accountKey - deterministic account key to derive all keys from
        outputScriptType - type of addresses (aka output scripts) to generate for receiving
      • lookaheadSize

        public KeyChainGroup.Builder lookaheadSize​(int lookaheadSize)
        Set a custom lookahead size for all deterministic chains
        Parameters:
        lookaheadSize - lookahead size
      • lookaheadThreshold

        public KeyChainGroup.Builder lookaheadThreshold​(int lookaheadThreshold)
        Set a custom lookahead threshold for all deterministic chains
        Parameters:
        lookaheadThreshold - lookahead threshold
