v0.1.0-beta.3

Breaking changes

  • Single-use-seals blinding factor changed from 32-bit to 64-bit of entropy

  • Test cases for BP mod strict encoding

v0.1.0-beta.2

Features overview

  • Complete validation workflow with new Validator object
  • Virtual machines for RGB contracts (interface + embedded VM)
  • Consignment now has a version field, so in the future more space-saving variants can be created (like removing txid from anchors and using short universal bitcoin IDs when BP node adoption will increase)
  • Anchor contains txid field; so validation can be performed with just Bitcoin Core (no Electrum or BP node is required). This also speeded up validation performance significantly.

Breaking changes

  • Change of TransitionId hash tag value (previously-generated transition ids will be invalid)
  • Change of GenesisId hash tag value (previously-generated contract/assets ids will be invalid)
  • TransitionId type is replaced with NodeId
  • NodeId and ContractId are now equal by value; ContractId is NodeId wrapper
  • ancestors() method moved from Transition to Node trait; genesis returns an empty array
  • Consignment endpoints contain NodeId information
