v1.6.0 release

This release includes the followings:

New feature

A feature to create/parse Output Script Descriptor has been added. Please refer to the wiki for usage instructions.

The Bitcoin::Descriptor class has existed until now, but breaking changes have been made to the interface to comply with the BIP specifications for each descriptor. If you have been using it in an older version, please check the changes.

Other changes

v1.5.0 release

This release includes the followings:

New features

• Add implementation of the cryptographic parts of BIP-324 Version 2 P2P Encrypted Transport Protocol. Both ruby and libsepc256k1 implementation.

Other changes

• libsecp256k1.dylib for macOS used in unit tests has been removed. you want to test using libsecp256k1 in an environment other than Linux, please set the path of the libsecp256k1 library to the environment variable TEST_LIBSECP256K1_PATH.
• Now compatible with libsecp256k1 v0.4.0.
• Refactor test case to use shared_example.
• Update bip-schnorr gem from 0.5.0 to 0.7.0.
• Update ecdsa_ext gem from 0.5.0 to 0.5.1. Accordingly, the monkey patch for ECDSA::Point#to_hex has been removed.

Bug fix

• Fix a bug where valid signatures would fail to be verified in Bitcoin::MessageSign#verify_message. This bug only affects you if you use the Ruby implementation of this library instead of libsecp256k1.

Full Changelog: v1.4.0...v1.5.0

v1.4.0 release

This release includes the following changes:

New Feature

• Add Bitcoin::Script#p2pk? method to check whether script is P2PK or not.

Bug Fix

• Fixed a bug where a Key object with a compressed public key was returned even if TYPES[:uncompressed] was specified for key_type in the Bitcoin::Key#generate method.
• Fixed a bug where an error occurred in the Bitcoin::Script#multisig? method when the number of signatures was an invalid value.

Removed feature

We have deprecated support for the BIP-70 Payment Protocol, as it has also been removed from Bitcoin Core. Along with this, the dependency on activesupport is removed.

Full Changelog: v1.3.0...v1.4.0

v1.3.0 release

This release includes the following changes:

• Add Bitcoin::PSBT::Tx#to_h method to output each PSBT data in Hash format.
• Add decodepsbt option in bitcoinrb-cli to decode Base64-format PSBT into JSON format.
• Return address of Bitcoin::Script#to_h changed to return a single address.
• Add BIP-322 message signing.
• Elliptic curve operations changed to be performed in Jacobian coordinates using ecdsa_ext gem and bip-schnorr gem v 0.5.0.
• Add private key length check in Bitcoin::Key#new.
  An incorrect public key was derived if a private key was specified with dropped digits that were not exactly 32 bytes and libsecp256k1 was used. This check ensures that an exception is thrown in such cases. The following code, which could also cause such cases, has been corrected:
  • Bitcion::ExtPubkey#derive
  • Bitcion::Taproot#tweak_private_key

Full Changelog: v1.2.1...v1.3.0

v1.2.0 release

This release contains following changes:

• Add support for Taproot Fields for PSBT(BIP-371)
• Add Bitcoin::Script#to_p2tr which creates P2TR script pubkey using xonly public key
• Add Bitcoin::Key#to_addr which returns address correspond to key_type value and #to_p2tr which generates P2TR address
• Some refactorings

See below for a complete list of changes:

Full Changelog: v1.1.1...v1.2.0

v1.1.1 release

This release fixes the following issues that occur in Ruby 3.1

psych 4.0.0 is now bundled with Ruby 3.1. Psych.load has been incompatible since psych 4.0.0. Accordingly, YAML.load has also become incompatible.

In bitcoinrb, YAML.load is used to load network settings in Bitcoin::ChainParams. This results in an error in Bitcoin::ChainParams when using bitcoinrb with Ruby 3.1.

This release resolves the error by using YAML.unsafe_load instead of YAML.load in Ruby 3.1+.

Full Changelog: v1.1.0...v1.1.1

v1.1.0 release

The following change are included in this release:

• Compliant with the BIP-174 specification for PSBT:
  We have been providing PSBT feature for some time now, but several keys have since been added to BIP-174. This release supports the following keys that have been added:
  • PSBT_GLOBAL_PROPRIETARY
  • PSBT_IN_PROPRIETARY
  • PSBT_OUT_PROPRIETARY
  • PSBT_IN_RIPEMD160
  • PSBT_IN_SHA256
  • PSBT_IN_HASH160
  • PSBT_IN_HASH256
• Replace extension of Object#build_json and to_h by open class with refinement(e4d4968).

v1.0.0 release

The following change are included in this release:

Taproot-related flags are now standard

The following flags when processing scripts are now standard flags:

• SCRIPT_VERIFY_TAPROOT
• SCRIPT_VERIFY_DISCOURAGE_UPGRADABLE_TAPROOT_VERSION
• SCRIPT_VERIFY_DISCOURAGE_OP_SUCCESS
• SCRIPT_VERIFY_DISCOURAGE_UPGRADABLE_PUBKEYTYPE

In previous versions, these flags had to be explicitly set when evaluating Taproot-related scripts.

The following fixes and improvements are included in this release:

• Bitcoin::PSBT supports PSBT data read from file and write to file.
• Bitcoin::Taproot::SimpleBuilder change following:
  • The interface that receives script and leaf version has been changed to an interface that receives Bitcoin::Taproot::LeafNode.
  • Bitcoin::Taproot provides some utility methods to help spending P2TR.

For more detail about how to build and spend P2TR, see the Wiki page.
