QuipSwap Is Live: Post-Quantum Swaps Anywhere to Anywhere
Cross-chain bridges accounted for 69% of all cryptocurrency stolen in 2022, and the largest DeFi loss of 2026 so far was another bridge exploit worth $292 million.
Quantum Annealer Versus Classical Solver on Live Portfolio Optimization
At our Quantum.Tech World 2026 booth, 98 people built portfolio-optimizer agents and every rebalance raced a classical solver against a D-Wave quantum annealer. Here is the method, and all 1,930 head-to-head results.
Quip Network at Quantum.Tech World 2026 in Boston
Quip Network sponsored Quantum.Tech World 2026 in Boston. This recap covers everything we did at the event, including our booth trading competition, our CEO's talk, and the Rare Qubits reception.
What Is Quip Network? A Primer
This is a primer on Quip Network: what it is, how it works, and what you can do with it today.
A new look for Quip Network
An evolved identity for a bigger mission. The Quip Network brand is rolling out a new logo, design system, and visual language today, designed in collaboration with Relate Studio.
Quip Network Brings Post-Quantum Protection to Bitcoin
Quantum-resistant Bitcoin protection, deployed on Arch Network's Bitcoin-native smart contract layer, is shipping without a soft fork, community vote, or risk of frozen funds. Open source and trustless, the architecture lets every holder upgrade while keeping their existing custody.
Quip Network Testnet Is Live
The first distributed quantum compute network, combining quantum and classical hardware in a single trustless marketplace, is now open for public testing. Open source and open to everyone, hardware operators of all types can participate and earn rewards.

Store now, decrypt later: the attack that starts before the computer exists
Quantum threats are unique. Store now, decrypt later is a strategy where an attacker records encrypted data today, stores it, and waits for a quantum computer capable of breaking the encryption to exist. The interception happens years before the cryptography even breaks, which means for long-lived secrets, the attack has already started. The deadline to secure secrets arrives before the machine does, because an attacker can record encrypted traffic now and decrypt it once the hardware exists.
Which blockchains are quantum resistant? The chain-level answer
Almost no blockchains are quantum resistant. Every major blockchain in use today settles ownership with elliptic-curve signatures, which a large enough quantum computer breaks. The work to change that is real and it is public, so it can be checked chain by chain rather than argued about. The test Quantum resistance means one thing at the chain level: the signature scheme that authorizes a spend rests on math a quantum computer cannot break. NIST finalized signature replacement schemes in 2024
Is Ethereum quantum resistant? The current answer
No. Ethereum today is not quantum resistant, and the interesting part is what that specifically means, because most of what people fear is wrong and the real exposure is narrower and more actionable. What breaks and what does not Ethereum accounts are secured by ECDSA signatures over the secp256k1 curve. A sufficiently large, error-corrected quantum computer running Shor's algorithm derives a private key from an exposed public key, which forges transactions from that account. That machine doe
What is a post-quantum wallet?
A post-quantum wallet is a wallet whose ownership rests on cryptography no known quantum computer can break. That one sentence does a lot of work, so here is what it means in practice and how to tell a real one from a label. The problem it solves Ordinary crypto wallets, MetaMask accounts and hardware wallets alike, prove ownership with elliptic-curve signatures. Shor's algorithm on a large enough quantum computer breaks those, deriving your private key from a public key you have already expo
What does it actually cost to run a job on a quantum computer in 2026?
Quantum vendors quote most of their prices on request, and the ones they publish sit on pages almost nobody reads. We go through the three ways to buy quantum compute in 2026, what each one charges you for, and why paying for an answer differs from paying for the machine.
Can a quantum computer break Bitcoin?
Every few months a quantum computing headline sends this question around again, and the answers on offer run from "tomorrow, sell everything" to "never, ignore it." The accurate answer is more specific than either, and it turns on which part of Bitcoin you mean. The short version No quantum computer that exists today can break Bitcoin or Ethereum. The machine that could is being built in public, by teams at Google, IBM, IonQ and Quantinuum. What it threatens is narrower than most coverage sug
