About StarkWareQuantumBTC
StarkWare said it completed the first quantum-secure Bitcoin mainnet transaction experiment, moving 10K sats into storage with added protection. Future quantum computers could break Bitcoin's current signatures; this approach adds a hash-based backup lock for specific funds without changing the protocol. It does not make Bitcoin quantum-safe. Each use takes hours, costs ~$150-$200 and needs miner coordination. Can it become practical for wallets and custodians?

Bitcoin just took its first serious step toward quantum resistance.
StarkWare has successfully demonstrated what it calls the first quantum-resistant transaction on the Bitcoin mainnet.
The transaction used Quantum Safe Bitcoin (QSB), a method designed to protect BTC from future quantum attacks without changing Bitcoin’s current consensus rules.
Why does this matter?
Bitcoin currently relies on cryptography that a sufficiently powerful quantum computer could theoretically threaten in the future.
QSB uses hash-based cryptography instead, creating another possible security path.
But there is an important catch.
This is not a permanent Bitcoin upgrade.
The experimental transaction required direct submission to a miner because the format is not currently relayed by standard Bitcoin nodes. The computational cost is also far higher than a normal transaction. 1
So I wouldn't call this “Bitcoin is now quantum-proof.”
It's better described as a proof that quantum-resistant spending can work on the existing network.
And StarkWare isn't alone.
Blockstream researchers have also proposed SHRINCS, another hash-based approach designed to protect Bitcoin against future quantum threats.
This could become one of the most important blockchain security conversations of the next decade.
Because the question isn't whether quantum computers can break Bitcoin today.
They can't.
The question is whether Bitcoin can upgrade its security early enough before that technology becomes a real threat.

Would you trust Bitcoin more if it had a fully integrated post-quantum security layer?

LATEST: StarkWare completed a quantum-resistant Bitcoin transaction on mainnet using Avihu Levy’s QSB method, showing it can work under existing rules but requiring up to $200 in off-chain computing.

What actually convinced me to keep studying $BTC is how its security model stays independent of any central operator. Bitcoin combines decentralized validation, predictable monetary issuance, censorship resistance, and a settlement network that has operated globally for years. Most projects usually achieve only one or two of these properties#IranSanctionsAndTalks #BTC80KHoldOrFold #AIEarningsWatch
BITCOIN JUST TOOK AN IMPORTANT STEP TOWARD QUANTUM SAFETY.
StarkWare successfully moved $35 in BTC using a quantum-resistant signature. The test worked, but it cost several hundred dollars in compute.
For now, this isn’t supported by Bitcoin’s normal network rules. Regular nodes wouldn’t relay it, so the transaction had to be sent directly to a mining pool.
It also doesn’t protect the ~6.9M BTC already sitting in exposed addresses.
Still, this is a useful proof of concept and a positive step toward making Bitcoin safer against future quantum threats.
