Work done so far

Orbis Labs has performed thousands of hours of research and development, resulting in hundreds of pages of research and tens of thousands of lines of code.

This research and development breaks down into three key areas: zk-SNARKs, the Orbis protocol, and compilers and emulators. Here is what has been done in each of these areas:

  • zk-SNARKS:
    • Developing a universal TinyRAM circuit for creating zk-SNARKs verifying the results of smart contract executions(about 80% done)
    • Defined a formal circuit specification language (OSL)
    • Defined a spec of the circuit for verifying Orbis rollups
    • Defined a process for compiling OSL specs into circuits
    • Developing a formally verified implementation of the process for compiling a circuit spec into a circuit(about 20% done)
    • Defining an approach to off-chain recursive proof composition
    • Defined an approach for on-chain proof verification and began implementing it(less than 20% done)
  • Protocol:
    • Designed the layer 1 protocol
    • Prototyping the layer 1 contract(more than 90% done)
    • Designing the centralized layer 2 protocol(more than 90% done)
    • Designing the decentralized layer 2 protocol(less than 10% done)
    • Implementing the prover node(about 10% done)
    • Began exploring approaches to smart contract composability
  • Compilers and emulators:
    • Developed an LLVM backend for TinyRAM
    • Developed a TinyRAM emulator in Haskell
    • Developed a formally verified TinyRAM emulator in Coq
    • Developing an Untyped Plutus Core (UPLC) to C compiler (in testing phase)

Note: the Orbis L1 contract and prover node are closed source for the time being. They will be open source at a later date.

Roadmap

Overall estimates of the state of completion of the design and implementation effort required to release Orbis V1, the ratio (effort expended / (effort expended + effort remaining)), broken down by area and expressed as percentages:

  • zk-SNARKS: 40%
  • Protocol: 33%
  • Compilers and emulators: 90%

The roadmap calls for releasing Orbis V1 in late 2022 or Q1 2023. The project is currently on track to release on this timeline.
