🕐 Weekly meeting (Mondays - 13:00 UTC) call doc. 📞

📆 2018/09/03 📆

attendees: Jaynti, Sami, Esteban, Johba

Updates:

[Jaynti] updates on hydrated state op-code execution, see PR 9.
[Kosta] Only storage tests left. Written the implementation (not committed) but hit out of gas again. see PR 5.

Questions:

[Esteban] move meeting to 1 hours earlier ✅
[Johann/Jaynti] how can state be exited? => Johann will write design for exitable state object and share with others.

📆 2018/07/24 📆

attendees: Jaynti, Vaibhav,Sami, Alex, Johba

Updates:

[kosta / johann] update on off-chain executor, see PR.
[johann] hydrated state architecture
- tasks are independent, can be started on already
- Jaynti: will work on this till next week

Questions:

how likely can we use EIP726?
- needs to be implemented in all clients => like months/years away.
how to design contract exit games? Contract Shell Exit Proposal
- open problem: when should exits be possible?

📆 2018/07/16 📆

attendees: Matheus, Jaynti, Vaibhav, Ashish, Sami, Esteban, Alex, Kosta, Johba

Introductions:

Matheus ✋
- Voting projects, research into Plasma since 2017.
- Latest code: JS implementation for stealth addresses and ring signatures with Lotion.js as Plasma chain.
- Liveliness is a problem / looking at Swarm to fix availability problem.

Updates:

Jaynti => Digested Computation 💡
- Integrate VM state hashing into execution after each op-code.
- Commit merkle tree of all steps with block to root chain.
  => Allows to do direct challenges without binary search. 🎉
  => Downside of potentially big performance impact. 😅
Sami => Stack Proofs as Unbalanced Merkle Tree 🎉
- The stack proof can be an unbalanced merkle tree.
  => Popping and pushing super easy. 🎉
  => Probably max top 7 elements needed, rest in regular hash.
Johba => General Updates
- Posted 2 bounties to Gitcoin: 1, 2
- More research needed into optimized proofs (hydrated state architecture).
- UTXO model allows limited contract interaction.
