Dug in and broke down the privacy terms I'm increasingly seeing 👇 Multi-Party Computation (MPC) — Distributed computation that allows multiple groups to collectively compute something without revealing their own information. ➢ Think you and five friends want to find your average salary without revealing individual amounts. Each person splits their salary into six random shares and sends one to each person. Everyone performs math on the shares to compute the final average without learning individual salaries. Building with MPC: Fireblocks (institutional custody), Arcium (private AI processing), Renegade (onchain dark pools) Fully Homomorphic Encryption (FHE) — Allows data processing without decryption, meaning sensitive data remains encrypted when stored, transmitted, and analyzed. ➢ Like a locked safe with programmable gloves. You put private data inside, program instructions, send to someone else. They operate blindly following instructions without seeing what's inside, return correct results. Building with FHE: Zama (FHE tooling), Fhenix (real-world applications), PrivaSea (encrypted ML) Trusted Execution Environments (TEEs) — Secure hardware zones that store and process data in isolation, preventing the rest of the machine from accessing that data. ➢ Think iPhone biometrics. Face scans stored in secure chip zones, matching happens inside sealed hardware. Apps only get yes/no, never see actual biometric data. Building with TEEs: Space Computer (satellite nodes), Oasis Protocol (confidential smart contracts), Phala Network (decentralized cloud) zkTLS — Merges TLS with zero-knowledge proofs to keep information private yet verifiable, turning any Web2 platform data into a public API. ➢ Prove your bank balance for onchain loans without revealing exact amounts or transaction history. Generate ZKP of balance, submit to DeFi platforms for creditworthiness verification. Building with zkTLS: ZKP2P (on/off ramps), EarniFi (privacy-preserving loans), DaisyPay (influencer payouts) https://www.bankless.com/read/cryptos-privacy-tech-wave

Guide to using ZKP2P's V2 for a privacy-preserving, low-cost way to move funds on/offchain: Here’s what it solves and how it works. 👇 Crypto payments still face key friction points for onboarding: ➢ High Fees: Moonpay charges up to 4.5%, andTransak $1 + 3.5% ➢ Cumbersome KYC: Different levels, tied to user accounts ➢ Limited Asset Support: Only a subset of onchain assets ➢ Inconsistent Availability: Coinbase works smoothly, but not everywhere ZKP2P matches buyers (onramping) with sellers (offramping), fixing this. In V1, sellers locked $USDC in escrow. Buyers sent fiat via Venmo, generated a payment proof, and unlocked funds. | What’s New in V2 V2 keeps the buyer/seller core but now uses zkTLS — a method for moving data from Web2 to Web3 without exposing private details — to match offchain and onchain parties. Users can now on/off ramp any ERC20 across Base, Polygon, Ethereum, and Solana, with new payment proof types (API, receipt, email confirmation). It also adds "offchain relayers" that differ by service: the default ZKP2P relayer abstracts gas and wallet signing, while others may add KYC or specialize in certain regions or providers. The result: a more flexible, developer-ready protocol that builds on V1’s foundation. | If I must prove receipt, how private is ZKP2P? ZKP2P doesn’t hide payments — it proves they happened without exposing personal data. Instead of KYC, users generate cryptographic proofs locally showing that a payment occurred and that they own the account — including only what’s needed (transaction ID, date, amount, etc.). Nothing is stored; all data lives in the browser and disappears after. This works through PeerAuth, a browser extension that uses zkTLS to pull info from Web2 payment apps (Venmo, Wise) and generate proofs, revealing only what's necessary. Everything is open source, and network activity can be inspected to confirm no leaks. | How to Onramp via ZKP2P 1. Visit zkp2p (dot) xyz & Connect Wallet — Use “Log In” in the top-right corner, then go to the Buy tab. 2. Start Your Order — Choose currency and payment method, pick an offer, then start and sign the order. 3. Install PeerAuth — Prompted after starting your first order. Click “Add to Chrome.” (While installing an extension in crypto usually feels risky, the doxxed founders and Ethereum Foundation support for ZKP2P make me more comfortable doing so.) 4. Make Payment — Follow payment instructions (QR code or manual), then click “I have completed payment.” 5. Verify & Receive $USDC — Log into your payment app, PeerAuth fetches details, select the correct transaction, click Verify, wait ~30s, then complete the order and receive funds. Support is available via their docs and Telegram. If you want to sell on ZKP2P, follow their guide to get started. --- ZKP2P is faster and cheaper than most onramps. Fees stay low (sometimes zero for small amounts), though they can creep up with size — easily solved by splitting into smaller orders. I’ve had $5 transactions where I paid the exact rate, onboarding USD with Venmo for zero cost — genuinely impressive. Still, ZKP2P isn’t yet as cheap or convenient as Coinbase for Base users in supported areas. Even so, usage keeps climbing as the protocol moves toward delivering the kind of seamless, private crypto payments the space has promised for years.

USDhl's pretty wild. Quick TLDR 👇 Initiative from Felix & M0 for a HL native, treasury-backed stablecoin that recycles rewards back into ecosystem rather than going to a private company like Circle. In the case of USDhl, all Treasuries yield is redistributed as $HYPE rewards to holders on a weekly basis. Grown to $27M Market Cap in 2 weeks since release. Now, USDhl also powers the first tokenized version of HLP live via HyperLend & Loop Collective — a long-awaited, hyped project to come. Given Felix's diligence in risk assessment, this rehypothecation doesn't really raise too many concerns for me, though mixed with all the companies buying $HYPE may be a concern at some point. I'm still bullish though & that wouldn't change if this happens — I'm just noting it could. https://x.com/Looped_HYPE/status/1936173802163257771
