The digital job market is facing an unprecedented wave of highly sophisticated hiring scams. Protecting your personal data is no longer optional.
Introducing JobShield AI, engineered by Devxyn Studio. This platform combines a forensic AI scam detection engine with a secure blockchain registry to identify and flag fraudulent job listings, dead corporate domains, and spoofed recruitment networks in real-time. 📈🔐
We have just opened our live beta preview, and the engineering team is looking for community feedback.
If you are currently on the market, we invite you to use JobShield to test any active job posts or recruiter communications you find questionable. Your real-world data and insights will directly help us optimize our risk-scoring algorithms.

Stacks Shield
Private peer-to-peer payments on Stacks Blockchain a Bitcoin Layer 2 , powered by zero-knowledge proofs.
Stacks Shield is a privacy application that enables users to shield STX and SIP-10 assets such as sBTC and USDCx, transfer value privately, split and merge shielded notes, and withdraw funds to a transparent Stacks address.
The application addresses a simple problem: blockchain transactions are publicly visible, making it difficult for users to maintain financial privacy when sending or receiving assets.
Stacks Shield uses zkSNARKs to prove that private transactions are valid without exposing the underlying note ownership and transaction details.
WHAT USERS CAN DO
Shield STX, sBTC, or USDCx into a private pool
Scan for their encrypted shielded notes
Transfer assets privately to another shielded address
Split shielded notes
Merge shielded notes
Withdraw assets to a transparent Stacks address
The application has been tested end-to-end on Stacks Testnet with STX, sBTC, and USDCx.
HOW WE BUILT IT
The privacy protocol is powered by a stack of zero-knowledge infrastructure, including zkSNARK circuits, zkVerify, Stacks/Clarity smart contracts, an API, relayer, and a developer SDK.
For this challenge, we used Bubble to design and build the frontend application, creating the user interface and interaction experience that brings the underlying privacy infrastructure together into a usable product.
The goal was to make a technically complex ZK privacy system feel simple from the user's perspective: select an asset, choose an operation, and let the application handle the underlying cryptography and blockchain infrastructure.
WHY BUBBLE
One of the reasons we chose Bubble for the frontend was to focus on product experience rather than spending the challenge rebuilding UI infrastructure from scratch.
Bubble allowed us to rapidly design and build the application interface around an already-working blockchain privacy protocol and turn a complex ZK workflow into a user-facing application.
The result is a frontend where users interact with familiar payment flows while the underlying system handles shielded notes, proofs, verification, relaying, and Stacks transactions.
