Thanks to the wonderful work of GetBlok.io I am experimenting with a plasma based staking setup. It would seem like the setup on chain will be significantly simplified, allowing everything to be contained in one box, rather than having multiple contracts and one stake box per staker. How much more efficient the different transaction types will be remains to be seen, but simplification of on chain code is a big win no matter what. It also opens up for storing snapshots of the stake state (in the form of an AVLTree) to open up for delayed rewards, similar to how staking rewards lag on cardano. My early work can be found here, nothing functional yet though: https://github.com/ergo-pad/paideia-contracts/tree/main/paideia_contracts/contracts/plasma_staking

KaChing!

buiding Web UI for configuring webhooks to users' service
Looking for design partners who want to create a payment processor on top of ka-ching. It can also track unconfirmed tx so the reaction can be almost instant. Once the user submits the transaction a chained tx can be generated. KaChing will handle the tx tracking, and you focus on your business logic.
The raffle bot is in production with a fixed bug https://github.com/zkastn/ergo-raffle-bot, open-sourced anyone can use.
the author of the raffle bot is about to start working on ErgoDex real-time order view on top of KaChing, with WebSockets and stuff, making ErgoDex alive and transparent for all.

dappstep

release the second part of the course
https://www.youtube.com/watch?v=742qiUg5pxY
added support for split change if there are two many boxes to the transaction builder.
added chained txs support
Isomorphic-wallet - same api as dapp connector, but on backend https://github.com/nirvanush/isomorphic-wallet, works great with ergoscript.js too.

CCheese Enthusiast @6directions Maybe this would help you with Ergonames?

6directions•7/27/22, 1:20 PM

Heh, yes. I've actually thought about this, but haven't implemented it

.

I think it would work well for lookup.

I have some unanswered questions/doubts about concurrency and updating the "lookup registry" though.

Sorry for the late reply, been super busy. But if you have some time next week, mind if consult a few things with you about implementation details? cc @Luivatra

Dexy USD contracts: adding a custom rate tracker to LP box

scalahub•7/27/22, 1:20 PM

Reviewed babel fees EIP. No issues found as such

scalahub•7/27/22, 1:22 PM

(custom rate tracker implies that we can add any percent, say 95% and the box will track when the oracle/LP rate last crossed it from above/below)

Node:

4.0.35 released
reviewing PRs for 4.0.36
back on finishing bootstrapping with UTXO set snapshot (will do EIP on that)

Dexy:

the paper has an alternative to burning described now

Other matters:

With the last Update Pool Box command implemented, we will have all the parts ready. Next is to test how it flies as a whole.

I'll get back to launching and running an oracle pool on testnet as a smoke test after I finish with current urgent sigma-rust issues (token burn, dist sigs, etc.). After that and a few housekeeping tasks, I believe we will be ready for an open public test.

kushti•7/27/22, 1:55 PM

@Cheese Enthusiast @Luivatra i think we can have plasma-or-rollup kind of design, where publisher is publishing state digests and update digests, and only in case of contestation publishing a rollup, against which it could be another contestation. So minimal plasma load in optimistic case, rollup in case of a dispute

Ccapt_nemo Wow, that's interesting 🤔
