- The future of consensus in Indy Node (moving from RBFT to Aardvark?)
- Indy / Aries split
Timezone: US morning and Europe afternoon
We intend to record this call.
Linux Foundation meetings involve participation by industry competitors, and it is the intention of the Linux Foundation to conduct all of its activities in accordance with applicable antitrust and competition laws. It is therefore extremely important that attendees adhere to meeting agendas, and be aware of, and not participate in any activities that are prohibited under applicable US state, federal or foreign antitrust and competition laws.
Examples of types of actions that are prohibited at Linux Foundation meetings and in connection with Linux Foundation activities are described in the Linux Foundation Antitrust Policy available at http://www.linuxfoundation.org/antitrust-policy. If you have questions about these matters, please contact your company counsel, or if you are a member of the Linux Foundation, feel free to contact Andrew Updegrove of the firm of Gesmer Updegrove LLP, which provides legal counsel to the Linux Foundation.

- The future of consensus in Indy Node: proposal for moving from RBFT to Aardvark
- During the implementation of PBFT View Change, we tested PBFT selection of View Change and it seemed to be much better.
- Evaluating Aardvark versus fixing bugs with RBFT suggest that we should proceed to implement Aardvark.
- Evernym is considering doing this in 2019, but has not made a decision.
- Theoretical method growth in Ardvaark is n^2 instead of n^3 in RBFT.
- In theory, view change for RBFT is faster than in Aardvark / PBFT because the nodes have more information stored in the shadow masters.
- So there is a trade-off between faster view change versus faster throughput.
- Under attack, RBFT is expected to have more consistent throughput than regular PBFT and Aardvark.
- In practice, we would be using the same implementation of view change.
- How often does view change happen in practice?
- Under RBFT, view changes in the real world appear to be rare (days). It depends on the network conditions.
- We can select the Aardvark performance threshold to have regular view changes with the frequency we would prefer, under good network conditions.
- Update on Indy / Aries split
- foundation's POC on threading is currently on-hold.
- Adam has been looking at Rust parallelization / threading libraries. (See the Rocket framework for web servers for a good example.)
- Handlers vs Futures vs async/waits
- RFC for 37: Present Proof
- Describes a new object for presentation previews. Fills a gap in LibIndy; interim solution until we have full blown W3C VCs.
- Evernym thinks the next step is to move the Indy Wallet to Aries
- As an Indy / Aries community, do we always have to wait for consensus on the details before people can contribute code?
- Define pull request review process for Indy Node.
- Should define the process, including how we handle exceptions (emergency fixes shouldn't be blocked, but would require notification)
- What is important in a good review?
- If a review must be skipped, should note it in the Git commit message.
- Non-secrets in the Indy Wallet
- Cam is working on pluggable crypto. They wallet shouldn't decide what encryption you should be using.
- Use cases where we would want to move keys between wallets
- Moving the link secret / credential data from one device to another (synchronized storage).
- Debug use cases
- Richard's hit other uses cases that were better solved with DID Doc, pre-signing, signing API.
