Akyba update.
Web dApp + mobile App in progress:
On-chain ROSCA group creation
Mobile signing (non-custodial)
Deterministic transaction flow
Getting close.
Stay tuned
Final session of our Formal Verification in Lean 4 course today.
Over 8 weeks the cohort went from Lean basics to theorem proving, SMT solvers, and a full smart contract audit workflow.
This is how we make audits rigorous instead of best-effort.
Formal verification for blockchains is what we do at @nowitnesslabs . More coming soon
@rvcas After learning ADTs, do you start seeing something uncomfortable?
How many systems are built around runtime validation of impossible states instead of designing those states out entirely?
@sibyog13 Les usages existent déjà : tontines, WhatsApp, Mobile Money.
Le vrai manque aujourd’hui, c’est un système simple et peu coûteux pour gérer contributions, distributions et défauts de paiement.
C’est exactement ce qu’Akyba construit.
@astroboysoup@v_vukman@wada_org Still early, we’re focused first on getting the ROSCA/stablecoin flow operational end-to-end. But M-Pesa is probably the most obvious first corridor given existing mobile money density and user behavior.
@astroboysoup@v_vukman@wada_org Exactly. The protocol logic is solvable. The hard part is operational liquidity and recovery flows.
A ROSCA can’t behave like DeFi liquidation logic. Missed rounds need social + liquidity buffers, not just smart contract enforcement.
@astroboysoup@v_vukman@wada_org Ok. Demand already exists.
The real battle is rails:
mobile money <-> stablecoins <-> local agent networks.
Once that bridge is seamless, it stops being “crypto” and becomes financial infrastructure.
“Low purchasing power” does not mean “low opportunity” when the problem space is massive and structurally unsolved.
And dismissing an entire continent as “uneducated” is not analysis. It’s bias.
@astroboysoup@wada_org That African narrative leads us nowhere, and it's been pushed forward since 2022. Sure, Africa is an opportunity because they're unbanked, but their purchasing power is so low, and people are so uneducated that all that focus on Africa makes no fu... business sense.

The real question is not “how many projects?”
It’s:
How many MVPs shipped?
How many users onboarded?
How many teams still building after 6 months?
Africa doesn’t need more ecosystem reports.
It needs durable products and real adoption.
989,901 ADA to turn African hackathon projects into startups.
@wada_org is proposing a 12-month incubator after CATS 2026, taking 20+ projects across 10–12 hubs from hackathon ideas into MVPs, GitHub repos, pitch decks and Demo Day.
The upside: this targets the awkward gap after hackathons, where good ideas usually die.
The concern: reporting needs to be very concrete.
Does this create real Cardano builders and users, or more ecosystem activity reports?
*Not a paid promotion
Crypto rebuilt markets
It didn’t rebuild trust-based savings
ROSCA isn’t DeFi:
it needs fixed groups, cycles, enforcement
That’s why almost none exist on-chain
Akyba makes it deterministic:
no contribution -> no payout
