Support Blockchain Reorganization

Open eukreign opened this issue 6 years ago • 3 comments

  • [ ] implement support for detecing reorganizations and recovering
    • [x] rewind the headers
    • [ ] undo any transactions
  • [x] unit tests for rewinding headers
  • [ ] unit tests for dropping transactions that happened on removed blocks
  • [x] integration tests using generate and invalidateblock commands

how do reorgs affect files you have on disk and claims you paid for?
