observations:
- alpha was party A for both others (and failed both)
- beta was party A for gamma (and failed gamma)
Is something wrong with party A attestation?
[Cantillon] worker.getRegistration returns very big number
see the test for the issue: https://github.com/encointer/polkawallet-flutter/blob/961bb097df0b00b2390ab54c7804ce27b87ba4cd/lib/js_service_encointer/src/service/worker.test.js#L45
This might be a more generic issue
test android app from scratch for new currency and one bootstrapping ceremony on Gesell Testnet
- install https://github.com/encointer/encointer-wallet-flutter/releases/download/v0.8.0/encointer-wallet-0.8.0.apk
on 3 phones. - Create bootstrapper accounts on phone
- register new currency
- perform meetup at one ceremony
- transfer freshly issued tokens from one account to another
improve user guidance during meetup procedure
currently, a QR code is shown with a button "done". This is misleading.
Every QR code should be clearly titled, like "claimA", "attestationA + claimB"
The button should name the next QR code to be scanned on the other device. More intuitive because we can assume that each user sees both screens
there should be a proper back-and-forth movement possible and it should always be clearly stated what the current step is.
The QR code scanner is now full of chinese symbols. Clean that up and replace with the title that should be scanned!
some refactoring of meetup function will be needed for this

could this be a reason for our bad js performance?
finish Cantillon support
- review worker api PR #16
- throughout code use
isEncointer,isEncointerCantillonisEncointerGesellflags to change behaviour and use worker api
replace account password with PIN code
good enough for banking apps, good enough for us I guess. Encointer is for everyday amounts anyway
- change keyboard to digits only. require 4 digits minimum
- remove password quality check
encointerBalances are displayed as zero even though we get non-zero values from js side.
enable offline meetups
Currently, we need to be online to start a meetup. The app should cache all Information when it goes online during assigning or attesting and should allow to start the meetup even without any connection to the chain
scenario:
- (online) user registers for next ceremony
- (online) during ASSIGNING phase, user starts the app to fetch meetup details

[Cantillon] worker.getMeetupIndexTimeAndLocation panics in worker
see the test for the issue: https://github.com/encointer/polkawallet-flutter/blob/961bb097df0b00b2390ab54c7804ce27b87ba4cd/lib/js_service_encointer/src/service/worker.test.js#L57
this has been tested with a call from the rust side, which works.
This might be a more generic issue with the getters

implement faucet in app
//Alice sends 0.001 ERT if balance < 0.0001
show tx history with correct fixpoint values and human readable cid&accountid
This will be done with the subscan api. Subscan does already support U64F64 so we will most-likely be able to use their service
Reference from assetsApi code that was used to get history of the native token. (Was removed in a cleanup: #520).

missing details
Registering
[ ] cid selector: display cid as base58, not hex
notify extrinsic result
currently, the app only confirms Broadcast but we get no feedback on DispatchResult. We should get that!
We may want to do #58 first as it might be done upstream?
fix register_attestations
no successful extrinsic so far.
nctr currency balances don't update correctly
In order for updated values to appear in the assets page. One needs to manually reload the listview or switch back and forth from the assets page.
This might be a bug with the caching.
Meetup Ceremony hangs
After scanning it fails to show 'AttestationA | claimB'. Then the screen returns to the initial meetup page and restarting the attestation procedure returns in the same result.
Probably the JS side either hangs on 'webApi.encointer.parseClaimOfAttendance(claimAhex)' or 'webApi.encointer.attestClaimOfAttendance(claimAhex, "pwd");'
upgrade to upstream polkawallet v1.0.1
polkawallet has several little issues with our base-version 0.7.6. We should benefit from their work of stabilizing polkawallet
create Attestation in js_service_encointer
a meetup participant will scan another one's clam as QR code, decode it and then
- verify contents of claim: are the following fields correct (equal to own claim)?
currency_identifier, ceremony_index, meetup_index, location, timestamp(this check does not necessarily need to be done in js, could be in dart too. ) - sign claim and generate
Attestation
This will in turn be encoded into a QR code for the claimant to be scanned
We therefore need a js function attestClaim consuming a SCALE encoded ClaimOfAttendance returning a SCALE encoded Attestaion in service/encointer.js
open questions:
- where do we verify? in js or in dart? Probably dart is easier for decent error handling than a hidden webview with js.
Unable to change between encointer networks
If the network is changed and the previous and the newly selected network is both from encointer, there is no connection initialized to the new network.
attestations feature unknown cid, leading to DispatchError when registering attestations

change pubkey for every ceremony by default for enhanced privacy
for Gesell, this is of minor impact because of the linkability risk due to ERT fee payments. At least, changing pubkeys may provide plausible deniability.
for Cantillon, incognito accounts are confidential anyway. Still, this countermeasure provides some forward secrecy in the event of STF state leakage due to SGX vulnerability
Theory to be elaborated further.....
erroneous meetup time
The displayed ceremony time in the assigning phase is wrong.
Setup: Gesell, currency: 39GtBdLnLPERXKJWCXaDBpjiiLv3Hbhthck1iNqArn9m:
Meetup 1:
The actual meeting time was 12:20 UTC.
The apps on the phones displayed: 2020-09-23T13:54
An app in the emulator displayed: 2020-09-23T14:10
Meetup 2:
The actual meeting time was 12:50 UTC.
Both, the phones and the emulator displayed: 2020-09-23T14:24
Remove hardcoded password in the meetup ceremony. ask once and cache it instead
For attesting the claim of attendance we need to enter the password.
This is currently hardcoded to 123qwe for dev/experience. Implying that we cannot perform the meetup with an account that has set a different password!
register_participant with ProofOfAttendance in js_service
Implement js_service_encointer functions to register a participant with a proof of attendance.
define a getProofOfAttendance function that returns a SCALE encoded Option<ProofOfAttendance> in js_service_encointer, probably in service/encointer.js. This function will be called from dart side in order to fill in this field
the js type definition is here
here's how encointer-client generates a proof of attendance
for our app, prover_public is equal to attendee_public because we don't change accounts between ceremonies yet.
to be tested against tesntet Gesell (or a --dev chain v0.2.1):
- register currency with well-known bootstrappers Alice, Bob, Charlie
- register as a non-bootstrapper (without proofOfAttnedance) with app and perform ceremony
- for the next ceremony, register with proof
- check reputation registry. If proof was accepted, querying
EncointerCeremonies ParticipantReputationfor the current cindex and cid should returnUnverifiedReputable
check bot script for how to automate this test.
Not sure yet how to test js_service_encointer standalone without dart app. There is a first standalone test script however
test all features on iOS and record video footage
implement meetup overview
- ask how many people are present
- show list of assigned participants with attestation status
https://tools.scs.ch/wiki/display/SCSBLOCKCHAIN/mobile+app+UX
implement the correct meetup time formula
currently, we're using a dummy timestamp in the app, causing #56.
This is no surprise when looking at the code:
encointer-wallet-flutter/lib/js_service_encointer/src/service/encointer.js
Lines 108 to 119 in 293e697
This should actually match the formula stated here:
https://github.com/encointer/encointer-worker/blob/2e77df9a7a5643720238314ecade392aaefa440c/stf/src/cli.rs#L617-L648
Add encoding from double to fixpoint
In order to transfer Encointer Community Currencies, we need to manually encode double values entered in the app to fixpoint.
create claimOfAttendance in js_service_encointer
in order to perfom a meetup, each participant has to generate a claim that will be signed by all other participants. Check how encointer-client generates this claim:
the n_participants vote will be supplied by the app user.
This claim will then be shown as a QR code to be scanned by others
implement registration view
- push notification if last ceremony has issued funds for our account
See UX design here: https://tools.scs.ch/wiki/display/SCSBLOCKCHAIN/mobile+app+UX
Show registering view when phase is registering
- unregistering is currently unsupported! Show it but inactive
Gesell Wallet functionality. Send community currency like ERT
- "asset" view should list (only) currencies where the balance is > 0
- these currencies can be sent to other accounts i.e. by scanning their QR code (as polkawallet asset view does it for our ERT token now)
- (optional) keep tx history like polkawallet does
Default setup should be Gesell when user installs and start the app
basic app rebranding and skeleton
started on https://github.com/encointer/polkawallet-flutter/tree/encointer
[x ] integrate encointer artwork and naming
[x] keep "assets" and "profile", add a tab for "Ceremonies"
[x] subscribe to CurrentPhase and display phase on "Ceremonies" tab
[x] dummy button to send register_participant extrinsic without proof of attendance
[x ] endpoint selection: Gesell and Cantillon
Quickstart
- install android studio & flutter
- set up AVD device (hit Ctrl-Shift-A and type AVD Manager)
- in WSL, run
cd lib/js_service_kusama/ yarn install yarn run build cd ../js_service_encointer yarn install yarn run build - set up AVD device
- "run"
implement bilateral attestation views
Query Cantillon worker's TrustedGetter from js_servcie_encointer (Balance, registrations, meetup info)
For the app to work with Cantillon, we'll need to implement the worker-api for the following Getters:
Assumptions:
- we use the same on-chain account also as our incognito account for offchain workers for simplicity (rust client can use different keypairs for on-chain and off-chain state)
Rust definitions for TrustedGetter:
https://github.com/encointer/encointer-worker/blob/35ae50a27b293971f2289d71ef3f81b604ae8d33/stf/src/lib.rs#L112-L117
rust client commands:
encointer-client-teeproxy trusted balance ....Rustencointer-client-teeproxy trusted get_registration ....Rustencointer-client-teeproxy trusted get_attestations ....Rust- get meetup assignment for claim generation: Rust
The TrustedGetter has to be wrapped multiple times:
- into a
TrustedGetterSigned(by signing it with our incognito account = polkawallet account) - into a
ClientRequestDefinition
then send request over websocket to : wss://substratee03.scs.ch
return value will be a hex::encode(SCALE::encode(value)). Can only be decoded if type is known:
- Balance is a
BalanceType - registration is
ParticipantIndexType - attestations is
Vec<Attestation> - meetup assignment is
(MeetupIndexType, Option<Location>, Option<Moment>)
We may want to query public stats too once they are available. See:

[Cantillon] WorkerApi: Some (maybe all) getters have some weird behaviour
implement proper state caching with dependencies and time-to-live
this is connected to #24, so think about that first!
The app is awfully slow now because we re-fetch all state with every change of phase or view. Moreover, the state can get inconsistent (register for a ceremony, wait for attesting, change selected currency -> registration status won't update)
We should have a proper caching which is aware when something is expected to change (because of offline considerations we may not want to work with subscriptions too much? check!)
Dependencies must be respected. Draw the dependency graph of all used onchain state for documentation purposes
Also consider that some state might be fetched from worker-api later (Cantillon)
[Cantillon] worker.getAttestations returns weird vector 1024 attestations
see the test for the method: https://github.com/encointer/polkawallet-flutter/blob/961bb097df0b00b2390ab54c7804ce27b87ba4cd/lib/js_service_encointer/src/service/worker.test.js#L69
This might be a more general issue with the getters.
[assets] show balance for selected encointer currency
nice to have: scan all currencies for a balance for current account
implement assignment view
show assignment status as soon as available when phase is: assigning
