MarginaliaZK

Fermat wrote it in the margin. We wrote it in the proof. $MGZK is live on Pons. CA: 0x7d8d7b6bcabfa1a617b8020395c5c8b49419a8ab On Robinhood Chain, every balance, every payroll, every counterparty sits on a public explorer. One transaction leaks your entire ledger. Marginalia closes the leak. A compliant zero-knowledge shielded pool. Deposits are inscribed into a depth-20 Poseidon Merkle tree, the Folio. Withdrawals are Groth16 zk-SNARKs, synthesized in your browser in ~3.6s. Nullifiers, the Wax Seal, make double-spends mathematically impossible. Payouts land at fresh addresses, unlinkable, relayed gaslessly by the Mersenne Courier. Not a mixer. Association Set Provider proofs let you prove your funds belong to a screened, non-sanctioned set without revealing which deposit is yours. Privacy for honest capital. Exclusion for the rest. $MGZK - Fair launch, bonding curve to Uniswap v4 - No presale, no team allocation - LP locked forever - 25% of creator fees → buyback & burn Every trade leaves a mark in the margin. Every mark burns. Honest engineering: testnet only, not yet audited. Mainnet is gated behind an external audit and a public Phase-2 MPC ceremony.

The time has come

Last step to mainnet with GROTH16 (first on rh) The proving key is only as honest as its most honest contributor. We're opening the Marginalia Phase-2 trusted setup ceremony, and we need you. Why it matters: Groth16 proofs need a proving key. If one party creates it alone, that party could forge proofs. So we don't create it alone. How it works: → Independent people each add secret randomness to the withdraw and ragequit proving keys → Each contributor discards their secret after contributing → If even ONE contributor is honest, nobody can ever forge a proof. Not us, not anyone → The final key is sealed with a public drand randomness beacon No ceremony, no mainnet. Our deploy pipeline refuses to push to Robinhood Chain mainnet (4663) without a completed ceremony transcript. Enforced by code, not by promise. The path: Recruiting → Contributions → Sealed → Mainnet We need at least 15 independent contributors per circuit. Every hash on the ceremony page can be checked yourself.

We are really close to Robinhood chain mainnet. Hold tight

2,000,000 $MGZK burned today. Right before mainnet. Burn tx: robinhoodchain.blockscout.co… Marginalia goes live on Robinhood Chain mainnet today. More burns follow after launch. What happens after mainnet: → The shielded pool runs on Robinhood Chain (4663) with real ETH → Deposit caps start low and rise as the anonymity set grows → Every withdrawal is checked against the Magistrate's screened set → Creator fees keep buying back and burning $MGZK What you can do, step by step: 1. Shield: deposit ETH into the pool. Your note is encrypted and stays in your browser. 2. Withdraw privately: generate a ZK proof in your browser and send funds to any fresh address. No link to your deposit. 3. Go gasless: use the Mersenne Courier. Your new wallet doesn't need ETH for gas. 4. Exit anytime: ragequit returns your deposit to your original address, no screening required. 5. Prove you're clean: generate a Letter of Disclosure for an auditor or exchange, without giving up spending rights. 6. Verify everything: check deposits, nullifiers, and roots on the Folio Explorer. Status: [audited by X / unaudited, guarded launch with deposit caps]. Only deposit what you can afford to lose.

Phase 02 complete. Hardening is live. Testnet Alpha is done: Robinhood Chain testnet, Next.js app, ragequit, encrypted vault. Now we harden. First up: relayer fee quoting. Gasless withdrawals have a hard constraint. The fee is a public input of the Groth16 proof, bound to recipient and relayer. Once the proof is built, nobody can change it. Not the user, not the Mersenne Courier. So the price has to be right before the proof exists. How we quote it: → Fee = p90 of real relay gas + 5% headroom + 10% margin → At relay time, the Courier runs estimateGas on the exact tx → If the fee doesn't cover the cost, it rejects before spending a single wei of gas Testnet results: 20 real relays. The fee covered the cost 18/18 times (the other 2 were E2E test runs). Still on the Hardening list: → Multisig Magistrate → IPFS-pinned label lists → Gas optimization Then: external audit and a public Phase-2 MPC ceremony. Testnet now, mainnet today.

What if your payroll stayed private on Robinhood Chain, and still passed compliance? Next for Marginalia: → Hardening → External audit → Public MPC ceremony → Guarded mainnet The margin was too small. The proof isn't.

19.83M $MGZK just burned before mainnet. mainnet tx/addresses will publish here on X soon. The margin was too small. Tx: robinhoodchain.blockscout.co…

Agreed, those are the two gates. Adoption starts with testnet users and builders on Robinhood Chain. The public MPC ceremony will be open to anyone, so the community helps secure the proving key. Mainnet launches with deposit caps that rise as the anonymity set grows. Updates soon.

Robinhood mainnet (really soon) What's next on Marginalia: the road to mainnet. What if your payroll could settle on Robinhood Chain without broadcasting every salary to a block explorer? What if a fund could rebalance tokenized equities without front-runners reading its intent? What if you could prove your funds are clean to a regulator, without showing them your entire history? What if privacy and compliance were never a trade-off, just two outputs of the same proof? That's what we're shipping to mainnet. The path, in order: 01 · Hardening Automated Magistrate screening, IPFS-pinned association sets, Safe 2-of-3 governance, Courier relayer health. Rolling out and soaking now. 02 · External audit Independent review of the Groth16 circuits and pool contracts. No shortcuts. 03 · Public Phase-2 MPC ceremony Anyone can contribute entropy. If one participant is honest, the proving key is sound. Our deploy script refuses mainnet without the transcript. 04 · Guarded mainnet Robinhood Chain (4663). Deposit caps that rise with time and anonymity set size. No dates until the audit is done. Math doesn't ship on vibes.
