hasChainCode

public boolean hasChainCode()

required bytes chain_code = 1;

 Random data that allows us to extend a key. Without this, we can't figure out the next key in the chain and
 should just treat it as a regular ORIGINAL type key.
 

Specified by:

hasChainCode in interface Protos.DeterministicKeyOrBuilder

getChainCode

public com.google.protobuf.ByteString getChainCode()

required bytes chain_code = 1;

getPathList

public List<Integer> getPathList()

repeated uint32 path = 2;

 The path through the key tree. Each number is encoded in the standard form: high bit set for private derivation
 and high bit unset for public derivation.
 

Specified by:

getPathList in interface Protos.DeterministicKeyOrBuilder

getPathCount

public int getPathCount()

repeated uint32 path = 2;

 The path through the key tree. Each number is encoded in the standard form: high bit set for private derivation
 and high bit unset for public derivation.
 

Specified by:

getPathCount in interface Protos.DeterministicKeyOrBuilder

getPath

public int getPath(int index)

repeated uint32 path = 2;

 The path through the key tree. Each number is encoded in the standard form: high bit set for private derivation
 and high bit unset for public derivation.
 

Specified by:

getPath in interface Protos.DeterministicKeyOrBuilder

hasIssuedSubkeys

public boolean hasIssuedSubkeys()

optional uint32 issued_subkeys = 3;

 How many children of this key have been issued, that is, given to the user when they requested a fresh key?
 For the parents of keys being handed out, this is always less than the true number of children: the difference is
 called the lookahead zone. These keys are put into Bloom filters so we can spot transactions made by clones of
 this wallet - for instance when restoring from backup or if the seed was shared between devices.
 If this field is missing it means we're not issuing subkeys of this key to users.

hasIsFollowing

public boolean hasIsFollowing()

optional bool isFollowing = 5;

 Flag indicating that this key is a root of a following chain. This chain is following the next non-following chain.
 Following/followed chains concept is used for married keychains, where the set of keys combined together to produce
 a single P2SH multisignature address
 

Specified by:

hasSigsRequiredToSpend

public boolean hasSigsRequiredToSpend()

optional uint32 sigsRequiredToSpend = 6 [default = 1];

 Number of signatures required to spend. This field is needed only for married keychains to reconstruct KeyChain
 and represents the N value from N-of-M CHECKMULTISIG script. For regular single keychains it will always be 1.
 

Specified by:

hasSigsRequiredToSpend in interface Protos.DeterministicKeyOrBuilder

getSigsRequiredToSpend
