Host: Olivia (PolyFlow)
In this episode of the PolyFlow PayFi Spotlight AMA, experts from identity verification, payment infrastructure, and privacy technology explored one of Web3's most pressing challenges: how to build compliant, seamless payment systems that bridge Web2 and Web3 while preserving privacy and user experience.
Host Olivia opened the discussion in New York, diving deep into reusable identity frameworks, zero-knowledge proofs, decentralized payment IDs, and the increasingly stringent compliance landscape in crypto.
Why PayFi?
Olivia began by highlighting PayFi’s mission: bringing seamless payments, compliance, and private identity into mainstream Web3.
The four guests shared their perspectives:
-
Joshua (ZKPass) positioned his company as a “private data oracle,” helping users verify Web2 account data on-chain without exposing personal information.
-
Ilya (Sumsub) introduced their latest reusable identity credential tool, enabling users to reuse KYC results across applications.
-
Shawn (Rozo Labs) discussed their privacy-focused, offline-capable Web3 eCash system currently in development.
-
Chuck (PolyFlow) unveiled PolyFlow’s newly launched Payment ID (PID), streamlining efficient and compliant identity verification.
The Rise of Reusable Identity
KYC has long been a pain point for users and platforms alike, with repeated document uploads and verifications degrading user experience. Sumsub’s Sumsub ID allows users to store verified credentials and reuse them across multiple platforms, significantly lowering entry barriers and friction.
Ilya stated: “We’re not just optimizing KYC—we’re making it legally valid and reusable.”
These credentials can also be used to issue on-chain proofs, easily integrated into dApps, wallets, or DeFi protocols, enhancing compliance flexibility.
ZKPass: Verifiable Private Data On-Chain
ZKPass demonstrated its solution using Zero-Knowledge Transport Layer Security (ZK-TLS), allowing users to prove certain attributes—such as credit score or deposit balance—without granting API access or signing data-sharing agreements.
Joshua gave an example: “Users can prove they have $10,000 in deposits or a 700+ credit score without revealing account details.”
This opens new use cases in DeFi and PayFi, such as credit lending and nationality verification, all while protecting user privacy.
PolyFlow PID: Your Web3 Identity Wallet
Chuck introduced PolyFlow’s Payment ID (PID), integrating identity credentials, transaction history, and reputation data into a single container—an “identity wallet for Web3.”
PID seamlessly integrates with Sumsub’s identity verification and ZKPass’s private proofs, empowering users to control their own data while increasing counterparty trust.
Additionally, PID includes a data monetization mechanism, allowing users to anonymously share select data for revenue. Chuck explained: “If merchants or advertisers serve ads based on your PID data, you earn a share of the revenue.”
Rozo Labs: The Value of Web3-Native eCash
Rozo Labs launched a Web3-native eCash system focused on privacy, instant settlement, and offline usability.
Shawn noted that while blockchain transparency is a strength, it also poses privacy risks. He illustrated: “Today, anyone can track all Vitalik.eth’s on-chain transactions—that’s a privacy crisis.”
Rozo Labs’ eCash will support network-independent payments, delivering an experience similar to NFC tap-to-pay, lowering adoption barriers.
Compliance: Centralized Pressure, Decentralized Future?
Divergent views emerged during the compliance discussion.
Ilya admitted: “Current regulatory frameworks largely outsource compliance to platforms, and that won’t change in the short term.”
Shawn envisioned a future where users complete a one-time KYC via government-backed ZK credentials and then autonomously authorize data access. While others agreed with the vision, they believe it may first emerge in emerging or lightly regulated markets.
Chuck added that major markets like the U.S. are tightening stablecoin compliance, while regions with high crypto adoption—like Latin America and Africa—may pioneer new compliance models.
Summary
This AMA highlighted three core trends:
-
Identity infrastructure is the foundation of PayFi, rapidly evolving through ZKP, reusable IDs, and decentralized data sovereignty.
-
Privacy and compliance can coexist, but require better tools and coordination.
-
Mass adoption hinges on user experience—smooth onboarding, intuitive wallets, and seamless payments are key to growth.
PolyFlow’s PID is emerging as a central hub in this ecosystem, serving both as a container for identity credentials and as a compliant gateway within decentralized payment networks.
