A short guide to what this app does, what it protects, and the order to use it.
01. WHAT_THIS_IS
AntiQuantum is four tools on Robinhood Chain. They exist because the signature behind most wallets, called ECDSA, falls to a large enough quantum computer. Machines today hold a few thousand noisy qubits. A fault-tolerant machine of the size in the public estimates is still ahead. The Global Risk Institute and evolutionQ surveyed 26 experts in 2025 and published the range in March 2026: a 28% to 49% chance within 10 years, and 51% to 70% within 15. NIST deprecates ECDSA around 2030 and disallows it in 2035.
02. WHAT_IS_AT_RISK
Think of your address as a box number. The public key is the shape of the lock. The first transaction you send shows that shape to everyone, and it stays public. A large enough quantum computer could cut a key from the shape. An address that has sent nothing has shown nothing. Scan reads that count, called the nonce, on the network you are connected to. Robinhood Chain is the home network. The same check works on any EVM chain you connect.
03. WHAT_IT_PROTECTS
AntiQuantum protects assets you move into it. The bunker is a time lock: you deposit now, and a withdrawal waits out a delay before it pays. That withdrawal is still signed by your current wallet key. The hash-based account is a new address. Spending from it needs a hash-based signature checked on Robinhood Chain. The signature rests on keccak256, which keeps about 128 bits of work against a quantum attacker.
04. WHAT_IT_LEAVES_OUT
Bitcoin stays on its own rules. Ethereum's validators stay on theirs. The keys that run this chain's sequencer, bridge, and upgrades stay on ECDSA until those systems change. Inside the app, the delay governor's admin is an ECDSA key, the ML-DSA check stays off in this build, the 24-word phrase is the only backup, and each leaf signs once.
05. YOUR_PATH
Start with Scan, so you know whether this address has already revealed its public key. If it has, the bunker can hold funds behind a delay today. Then make a hash-based account: generate the phrase, write it down, fund it, and spend from it. Last, Attest records a public note from the old key to the new account.
06. WORDS_YOU_WILL_SEE
- [ NONCE ]
- How many transactions this address has sent.
- [ PUBLIC_KEY ]
- The shape of the lock. The first outgoing transaction publishes it.
- [ ECDSA ]
- The signature most wallets use today. A large enough quantum computer breaks it.
- [ HASH-BASED_SIGNATURE ]
- A signature whose strength rests on a hash function, checked by a contract here.
- [ LEAF ]
- One of 1,024 one-time keys in your phrase. Each leaf signs a single spend.
- [ COMMIT_AND_REVEAL ]
- You publish a hash first, wait, then show the destination, the amount, and the cover phrase that match it.
- [ COVER_PHRASE ]
- A private code for one bunker withdrawal. The chain stores a hash, so the destination stays hidden until you reveal.
- [ COUNTERFACTUAL_ADDRESS ]
- The account address, known before the account contract is deployed.
- [ BUNDLER ]
- A service that submits the signed spend. Without one, the app shows the signed operation for you to send.
This app sells nothing and asks you to buy nothing.
