- trait AsyncExtSign extends AsyncAdaptorSign
A signing interface for ExtKey
- sealed abstract class BIP39Seed extends NetworkElement with MaskedToString
- sealed abstract class BaseTxSigComponent extends TxSigComponent
The TxSigComponent used to evaluate the the original Satoshi transaction digest algorithm.
The TxSigComponent used to evaluate the the original Satoshi transaction digest algorithm. Basically this is every spk that is not a WitnessScriptPubKey EXCEPT in the case of a P2SH(witness script) ScriptPubKey
- case class ChainCode(bytes: ByteVector) extends NetworkElement with Product with Serializable
- sealed abstract class ExtKey extends NetworkElement
Represents an extended key as defined by BIP32 https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki
- sealed abstract class ExtKeyPrivVersion extends ExtKeyVersion
- sealed abstract class ExtKeyPubVersion extends ExtKeyVersion
- sealed abstract class ExtKeyVersion extends NetworkElement
- sealed abstract class ExtPrivateKey extends ExtKey with ExtSign with MaskedToString
- case class ExtPrivateKeyHardened(version: ExtKeyPrivVersion, depth: UInt8, fingerprint: ByteVector, childNum: UInt32, chainCode: ChainCode, key: ECPrivateKey) extends ExtPrivateKey with Product with Serializable
- sealed abstract class ExtPublicKey extends ExtKey
- trait ExtSign extends AsyncExtSign with AdaptorSign
- sealed abstract class MnemonicCode extends SeqWrapper[String] with MaskedToString
A mnemonic code conforming to BIP39.
A mnemonic code conforming to BIP39. BIP39 mnemonic codes consist of a varying number of words (most often English, possible with other languages as well) that can be used to generate an ExtPrivateKey which again can be the root of a BIP32 HD wallet.
- sealed abstract class P2SHTxSigComponent extends BaseTxSigComponent
- sealed trait SignatureValidationError extends TransactionSignatureCheckerResult
Indicates that there was an error when evaluating the signature of a transaction
- case class TaprootSerializationOptions(tapLeafHashOpt: Option[Sha256Digest], annexHashOpt: Option[Sha256Digest], codeSeparatorPosOpt: Option[UInt32]) extends Product with Serializable
Options for the taproot signature serialization algorithm as defined in BIP341
- case class TaprootTxSigComponent(transaction: WitnessTransaction, inputIndex: UInt32, outputMap: PreviousOutputMap, flags: Seq[ScriptFlag]) extends TxSigComponent with WitnessTxSigComponent with Product with Serializable
Tx sig component that contains the differences between BIP143 (segwit v0) transaction signature serialization and BIP341.
Tx sig component that contains the differences between BIP143 (segwit v0) transaction signature serialization and BIP341.
The unique thing with BIP341 is the message commits to the scriptPubKeys of all outputs spent by the transaction, also
If the SIGHASH_ANYONECANPAY flag is not set, the message commits to the amounts of all transaction inputs.[18]
This means we need to bring ALL the outputs we are spending, even though this data structure is for checking the signature of a _single_ output.

- trait TransactionSignatureChecker extends AnyRef
Created by chris on 2/16/16.
Created by chris on 2/16/16. Responsible for checking digital signatures on inputs against their respective public keys
- sealed trait TransactionSignatureCheckerResult extends AnyRef
The result type returned by checking a signature
- sealed abstract class TransactionSignatureCreator extends AnyRef
Created by chris on 7/21/16.
- sealed abstract class TransactionSignatureSerializer extends AnyRef
Created by chris on 2/16/16.
Created by chris on 2/16/16. Wrapper that serializes like Transaction, but with the modifications required for the signature hash done https://github.com/bitcoin/bitcoin/blob/93c85d458ac3e2c496c1a053e1f5925f55e29100/src/script/interpreter.cpp#L1016-L1105 bitcoinj version of this https://github.com/bitcoinj/bitcoinj/blob/master/core/src/main/java/org/bitcoinj/core/Transaction.java#L924-L1008
- sealed abstract class TxSigComponent extends AnyRef
Created by chris on 4/6/16.
Created by chris on 4/6/16. Represents a transaction whose input is being checked against the spending conditions of a ScriptPubKey
- sealed trait WitnessTxSigComponent extends TxSigComponent
The TxSigComponent used to represent all the components necessarily for BIP143.
The TxSigComponent used to represent all the components necessarily for BIP143. Examples of these ScriptPubKey's are P2WPKHWitnessSPKV0, P2WSHWitnessSPKV0, and P2SH(witness script)
- sealed abstract class WitnessTxSigComponentP2SH extends P2SHTxSigComponent with WitnessTxSigComponent
This represents checking the WitnessTransaction against a P2SH(P2WSH) or P2SH(P2WPKH) scriptPubKey
- sealed abstract class WitnessTxSigComponentRaw extends TxSigComponent with WitnessTxSigComponent
This represents checking the WitnessTransaction against a P2WPKHWitnessSPKV0 or a P2WSHWitnessSPKV0
- sealed abstract class WitnessTxSigComponentRebuilt extends TxSigComponent
This represents a 'rebuilt' ScriptPubKey that was constructed from WitnessScriptPubKey After the ScriptPubKey is rebuilt, we need to use that rebuilt scriptpubkey to evaluate the ScriptSignature See BIP141 for more info on rebuilding P2WSH and P2WPKH scriptpubkeys
