Plenty of teams ship one or two of these. Web0 ships all four — and they are **live on Solana mainnet today**. This page is the receipts. *** ## 1. The whole row, not one box The agent economy needs four things at once — verifiable **proofs**, a **payment rail**, **privacy**, and **agent identity**. Look at where the checkmarks land across the field: | Approach | ZK proofs | x402 payments | Privacy | Agents / Passport | | -------------------------- | :-------: | :-----------: | :-----: | :---------------: | | ZK-proof toolkits | ✅ | ❌ | ✅ | ❌ | | x402 payment platforms | ❌ | ✅ | ❌ | ⚠️ | | FHE / confidential-compute | ❌ | ⚠️ | ✅ | ⚠️ | | **Web0 / DNA x402** | **✅** | **✅** | **✅** | **✅** | Plenty of teams ship one or two of these. Categories, not call-outs — the point isn't any single project, it's the **shape** of the field. The point isn't that any single box is hard. It's that **the combination is the moat**: * A **ZK toolkit with no payment rail** can prove things — but it can't bill an agent. * A **payment rail with no privacy** is a permanent public ledger of everything your agent has ever done. * **Privacy with no identity** has no one to attach a reputation to. Web0 is the only one with the **full row** — and it's verifying on mainnet, not sitting on a slide. *** ## 2. Same rail as Coinbase — the opposite default Coinbase's x402 made machine-to-machine payments real, and it's a genuinely good open standard. We **use** it. But x402 on its own is **public by default**: who paid whom, how much, and when — recorded forever. For an AI agent making thousands of calls a day, that's a permanent surveillance trail with great UX. | | Coinbase x402 | Web0 (Dark NULL) | | ----------------- | ----------------- | ------------------------------ | | Standard | x402 | x402 — **same standard** | | Agent payments | ✅ | ✅ | | Who-paid-whom | public, permanent | **hidden** | | Balance / history | public | **hidden, provable on demand** | | Reputation | — | **private track-record proof** | **They make transparency the default. We make privacy the floor.** Dark NULL lets an agent pay, prove it's good for it, and reveal *nothing else*. *** ## 3. `.null` vs the domain incumbents A `.null` name isn't just a label. It's a **payable, private identity**. | | ENS | Unstoppable | Web0 `.null` | | ------------------------- | ------------------------------ | ---------------- | ----------------------------------------------------------------------------------- | | Resolution | on-chain | centralized API | on-chain (direct PDA read) | | Content hosting | IPFS (you must keep it pinned) | their infra | **Arweave — permanent, paid once** | | Built-in payment endpoint | ❌ | ❌ | **✅ x402** | | Agent Passport | ❌ | ❌ | **✅** | | Resale | open public bids | open public bids | **open-ascending (English) — anti-snipe, instant on-chain refunds, fee capped ≤5%** | When you resell a `.null` name it runs as an open-ascending (English) auction: bids rise in the open, **every outbid is refunded on-chain instantly**, and an **anti-snipe** window extends the clock so nobody steals it in the final second. The protocol's cut is **capped at 5% in the program** — it can be lowered freely but never raised past that, and any raise is **timelocked 48 h on-chain**. The privacy in Web0 isn't in the *bidding* — it's in the payment and identity layer (Dark NULL): you pay and prove your reputation without exposing your wallet's history. *** ## 4. The part nobody can fake: it's LIVE Anyone can draw a comparison table. Here's what you **can't** fake — deployed on Solana **mainnet-beta**, verifiable in any explorer right now: | Program | Address | What it does | | ------------------------- | ---------------------------------------------- | ------------------------------------- | | `dark_x402_access_gate` | `EepqzVBNuzCgD6XGiB19pDDhzFG3gUL4z1nabBYxpfjS` | Pay-to-access, privately | | `dark_nullifier_record` | `24tmjEd1DhPW2QuPV6BzkFFHrq2PtELoLqv5cuv2Xu65` | Double-spend / replay shield | | `dark_reputation_gate` | `9nN7UTTT5hgKnc2LZTqr3qaLLSt5PxWUrDbpUTGYHRxp` | Prove a track record, reveal nothing | | `receipt_commitment_tree` | `8jC8QGiDJRRxhbPXMX5wJnGUq89xJZ2LsHMdbn2urCas` | Merkle root of private receipts | | `receipt_anchor` | `6HSRGivdYR5D7yTDy1TFMCM8h3LzXxRtKU1RA3RnCMRN` | Anchor receipts on-chain | | `null_registrar` | `H4wbFJucY9shJt95N8Bra532Z4nnkKhGEfqWvLcYfuDm` | `.null` names — paid, fee-flippable | | `null-auction` | `7uxLhqLzkEzPpkvdmTwqgL3g66yq2aMBS5QgcjaZZEaw` | English `.null` auctions + capped fee | …and that's on top of the Agent Passport, semaphore, and token primitives already live — **a dozen programs on Solana mainnet.** **And the cherry:** a *real* private track-record proof, verified on Solana mainnet: > `4eJCm2G9bmJWCnHJsHuYTqMondXSTW6DkctGmxNkxxppaKTjBoxWGwDZ187EetWcgw8zEdoE6CEfUjEXng6UEd4t` In the same run, **replay, forged, and tampered proofs were all rejected** on mainnet. That's not a promise on a roadmap. It's a transaction you can open in an explorer. *** ## 5. Why the right people trust us We could slap "audited" and "trustless" on this page. We don't, because they wouldn't be true yet, and the privacy crowd has a BS detector: * **Public Beta** — non-custodial, capped, and **not yet audited**. We don't claim "audited," and we won't put a fake date on one. * The ZK verifying keys are **single-party** until our **trusted-setup ceremony** finalizes. We're running that ceremony in the open. * Every claim on this page points to an **address or a transaction**, not an adjective. That restraint *is* the pitch. The proof is the on-chain link. *** **TL;DR** — Everyone else has a piece. We shipped the whole stack: ZK proofs **+** an x402 payment rail **+** privacy **+** agent identity, all live on Solana mainnet, all verifiable, with the caveats stated up front. That combination is the moat, and you can't fake it overnight. --- # Agent Instructions This documentation is published with GitBook.
