coinlib 4.0.0

A straight-forward, modular library for Peercoin and other Satoshi-based UTXO blockchains

4.0.0

• The TaprootKeyInput will now write an empty witness stack element to represent a missing signature. These inputs without a signature will be recognised when matching an input or reading a transaction.
• TaprootSingleScriptSigInput.anyPrevOutAnyScript() has been removed. All TaprootSingleScriptSigInput inputs now require the Taproot and TapLeafChecksig.
• Fixes Windows build sometimes hanging

3.1.0

• Add .r and .s getters to SchnorrSignature with a new .fromRS constructor. The underlying bytes for a BIP340 signature can be obtained via .r.x and .s.data.
• Add .xhex convenience getter for ECPublicKey.

3.0.1

Fix SchnorrInputSignature not using SIGHASH_DEFAULT.

3.0.0

This release adds support for ANYPREVOUT and ANYPREVOUTANYSCRIPT. There have been numerous breaking changes.

• Refactored SigHashType to use OutputSigHashOption and InputSigHashOption. Adds ANYPREVOUT and ANYPREVOUTANYSCRIPT.
• Add TapLeafChecksig for single signature checksig tapscripts
• Add TaprootSingleScriptSigInput to sign tapscripts using TapLeafChecksig. Can sign using ANYPREVOUT and ANYPREVOUTANYSCRIPT.
• Replaced sign() with signLegacy(), signLegacyWitness(), signTaproot() and signTaprootSingleScriptSig().
• Added SignDetails with numerous subclasses for providing signing details for inputs. SignatureHasher subclasses and Input sign methods refactored accordingly.
• Taproot signatures are made using SIGHASH_DEFAULT by default.

2.2.0

Add ECCompressedPublicKey class that forces compressed public keys.

2.1.0

Final release for 2.1.0

2.1.0-rc.1

• Add diffieHellman method to ECPrivateKey to allow generation of ECDH shared keys between two EC keys.
• Update secp256k1 to 0.5.0

2.0.0

Final release for 2.0.0

2.0.0-rc.6

• P2WSHAddress.fromScript is now P2WSHAddress.fromRedeemScript and P2WSHAddress.fromScript is now P2WSHAddress.fromWitnessScript to remove ambiguity.
• P2WSH.fromRedeemScript is now P2WSH.fromWitnessScript in accordance with usual naming for P2WSH.
• Added MultisigProgram.sorted to allow multisig programs with ordered public keys.

Reduce output size of JavaScript by encoding WASM as base64

2.0.0-rc.4

Fixed issues with build scripts

2.0.0-rc.3

Move secp256k1 code to secp256k1 directory

2.0.0-rc.2

Adds CoinSelection class with coin selection algorithms.

2.0.0-rc.1

• Add Taproot support for key-path spends and script-path spends.
• Taproot keys and MAST trees are provided with the Taproot class.

• NUMSPublicKey allows key-path spending to be omitted.
• Signing logic has been moved to the inputs.
• InputSignature renamed to ECDSAInputSignature and some other name changes.

1.0.0

Final release for 1.0.0

1.0.0-rc.3

• Make static variables immutable as final or const.

1.0.0-rc.2
