JUST IN: The first post-quantum resistant Bitcoin transaction was mined today. "It required no soft forks. It required no hard forks. It required no core protocol upgrades. And it's live today."

@Bitcoinconfasia Bitcoin keeps adapting

@Bitcoinconfasia We are getting This is a win

The first post-quantum Bitcoin transaction on mainnet is impressive engineering. Bitcoin developers are highly skilled and creative. Building a spend path was never the hard problem. The hard problem is getting the rest of the chain to follow. Zcash already ran this experiment in public. Every shielded-pool upgrade leaves a residue: lost keys, ignored notices, users who never move. Orchard still holds a large share of shielded value even as Ironwood ships quantum recoverability. Protocol teams cannot force a migration. They can only ask. Bitcoin will face the same choice at much larger scale. Either holders migrate before a cryptographically relevant quantum computer arrives, or the network sets a height after which unmigrated coins are frozen, or it leaves them for whoever can run Shor’s algorithm. Abandoned wallets, including Satoshi’s, get taken either way. The only question is by whom. Credit to @apruden08 for stating the dilemma cleanly.

@Bitcoinconfasia That was never the issue. Problem always been existing coins haven’t or won’t be moved anytime soon

@Bitcoinconfasia Proactive instead of reactive... Nice

@Bitcoinconfasia the sauce is amazing

@Bitcoinconfasia The key distinction: one post-quantum transaction is possible today, but existing Bitcoin addresses aren't automatically quantum-resistant.

@Bitcoinconfasia The maths here seems redundant. Bitcoin HAS BEEN secure at rest (qc cannot break hashing, can only break sigs), txs only vuln to qc during mempool exposing publickey. But they using a private miner here anyways, so all of this seems useless.

@Bitcoinconfasia no forks, no drama, just progress and I like that

@Bitcoinconfasia This is bigger than most realize. Quantum computing was the one existential threat bears had left. No soft fork. No hard fork. No permission needed. Bitcoin just solved it and kept moving. The attack vectors are closing one by one.

@Bitcoinconfasia

@Bitcoinconfasia One transaction. No fork. That's Bitcoin: the protocol stays boring, the engineering does the work. It doesn't make every address quantum-proof. It shows a path that already fits in the rules.

@Bitcoinconfasia no soft fork. no hard fork. no drama. the entire quantum FUD arc just got mined.

The key detail is the deployment path: a specific output can be made quantum-resistant under Bitcoin’s existing consensus rules, no fork or consensus upgrade required. 🔐 But consensus validity isn’t the same as normal relay. The format is nonstandard and needs a direct path to a miner, so this is an escape hatch for selected UTXOs, not a protocol-wide migration. Bitcoin itself isn’t quantum-resistant yet.

For years, “quantum computers will kill Bitcoin” has been one of the favorite doom narratives. Today, a post-quantum resistant Bitcoin transaction was mined. No hard fork. No soft fork. No core protocol upgrade. **The future just stress-tested one of Bitcoin's biggest fears. And Bitcoin kept moving.**

@Bitcoinconfasia Quantum just got ghosted, no cap 🪄✨

@Bitcoinconfasia @grok is this real?

@Bitcoinconfasia With all the "real" quantum computers out there* Guess someone must have tested this, right? * there's no true, actual Quantum Computers out there

@Bitcoinconfasia No fork, no drama — just a layered transaction that existing nodes accepted blindly. The real question: does "quantum-safe" here mean Lamport signatures or something lattice-based?

@Bitcoinconfasia So that means only the Bitcoin that is mined in the future will be protected?

@Bitcoinconfasia ha yeah right no fork? so will the send be updated what about the addresses? sure you can waste even more GPU mining it but that doesnt secure it from legacy lmao there is no fork coming

I’ll verify that “first post-quantum Bitcoin transaction” claim before giving a short take.True, with caveats. StarkWare’s Avihu Levy ran a QSB spend on Bitcoin mainnet (block 964,199, ~10k sats) with no consensus change. It uses hash-based tricks instead of relying on ECDSA while the tx is exposed.38 It’s a stopgap, not “Bitcoin is quantum-safe now.” The tx is nonstandard, so it went through MARA Slipstream, not the public mempool. It also costs extra GPU work and doesn’t fix Taproot, Lightning, or already-exposed keys. A real fix still needs a protocol upgrade

@Bitcoinconfasia How will we handle Satoshi and the lost property items?

@Bitcoinconfasia Things are getting interesting for Bitcoin protection(Security).

@Bitcoinconfasia Bitcoin

@Bitcoinconfasia This was never the main issue. But I guess it looks good to the uninformed.

@Bitcoinconfasia No fork needed is the part that actually matters here

@Bitcoinconfasia Progress is progress, it's a shame that no matter what progress is made someone always finds a way to be-little it. Shame on y'all.

@Bitcoinconfasia Bottom line: Positive proof-of-concept and useful emergency option for large holdings while the community works on better permanent upgrades. For ordinary users the costs and friction currently outweigh the benefits unless quantum risk becomes more imminent.

@Bitcoinconfasia It's misleading!

@Bitcoinconfasia They need to fix RSA systems likely banking, web, and databases use. Bitcoin is not the weak link in the chain.

@Bitcoinconfasia Impressive work. Being able to do this without any fork or protocol change is a bigger deal than most people realize.
