One can check if the payment(box) is in the chain without access to a trusted node.

EDIT: I mean with access to untrusted nodes only.

GetBlok.io Updates:

SubPooling:

Working on ergopad emission contracts
Integrating new ProxyPlasmaMap to help deal with unexpected errors while creating transactions (and before they are broadcasted)
Created custom sync function to sync off-chain data with on-chain digest in case of db corruption

Plasma:

Now on Plasma 0.0.8 (Still need to post this one on github)
Added ProxyPlasmaMap, which essentially allows operations to be performed on temporary tree identical to one in persistent storage. Modifications are queued internally so that once ready, operations done on the temporary tree are written into persistent storage. This method feels a bit safer than using db rollbacks (which I found could sometimes cause db corruption).
Working on write up for new plasma pool contracts that exist on mainnet. These contracts use chained transactions and separate contracts for different operations, making it easy to sync up with the current on-chain digest
Thinking about more modifications and improvements in general. If you've used the Plasma library and found something you don't like, then let me know!

-Work on mutual release agreement smart contract is ongoing, first milestone may have been reached but more on-chain tests are required to ensure we are on the right track.

-Met with developer to scope out the stack and process flow for users / artists portal - they are presently learning their way around Ergo (they have developed solutions for ETH platforms before so its not entirely new stuff to them)

-Discussed options with developer and settled on parsing markdown data as JSON, to optimally interface with Mosaik

MrStahlfelge•7/27/22, 3:05 PM

it is not only android (which would mean deploying appkit as an aar built by an own process), but also desktop (windows x86, arm, macos x86, arm, linux x86, arm64, arm32), ios x86/arm (x86 needed for the simulator) - this is 13 different targets, additionally some kind of automated JNI layer generator which is some kind of science on its own etc etc.

MMGpai what does one need to be connected to, in order to verify this?

greenhatOP•7/27/22, 3:05 PM

Well, actually you don't need to be connected per se. You just ask a few random nodes some queries.

TimL•7/27/22, 3:06 PM

Rust mostly covers all of the desktop. We're not using any OS-native code to my knowledge. ios is swift-based, so it will span over x86 and arm automatically. JNI, I don't know anything about

in progress: exploring additional GUAP token use case with GuapSwap PAY and GuapSwap OASIS enabling a potential mechanism for adverting token price deflation via accepting service fees in GUAP and sending them back to the emission contract (i.e. somewhat analogously to how miner fees work)
working on integrating landing page ui into actual frontend
using docusaurus for landing page and docs website
