The Poseidon circuit gadget and out of circuit implementation needs to support the full duplex mode in order to create Poseidon based halo 2 transcripts.

The main tasks related to this are:

  • Implementing the full duplex mode in the out of circuit implementation
  • Implementing the full duplex mode in the circuit gadget
  • Verifying through appropriate tests that the behavior of the circuit gadget matches the out of circuit implementation
  • Verifying through appropriate tests that the behavior of both match the Poseidon specification
  • Adding tests for edge cases
  • Handling padding in a better way than requiring manual padding
  • Improving the generic quality of the code
  • Merging to an upstream where it is usable
