I've been in Bitcoin long enough to have made every mistake.
Bought early. Lost some. Sold too early. Bought back in. Heard "quantum will kill Bitcoin" a dozen times and rolled my eyes every time — mostly because the people saying it were either academics writing for other academics or grifters selling fear.
But something changed for me this year.
When Google moved their Q-Day estimate to 2029 and told every engineering team on the planet to migrate to post-quantum cryptography immediately, I stopped rolling my eyes. Not because I panicked — but because I realized nobody was translating this stuff for regular Bitcoiners in a way that was honest, calm, and actually useful.
That's the gap StackerZero is trying to fill.
───
What it is
StackerZero is a Bitcoin defense and education project. Right now it's a website, a daily briefing, and a BIP tracker — built for serious holders who don't have PhDs but want to actually understand what's coming.
We cover:
• Post-quantum cryptography and what it means for Bitcoin specifically
• BIP 360 and the path to quantum-resistant addresses
• Silent Payments, Taproot, seed hygiene, and self-custody done right
• Plain-English translations of the actual science and the actual BIPs
No price talk. No moonboy energy. No FUD. Just signal.
───
The thought process
I'm not a researcher. I'm a guy from Maine who's been stacking sats, tinkering with Raspberry Pis and Flipper Zeros, and spending way too much time down technical rabbit holes. I got into Bitcoin because I believed in the idea — sound money, self-sovereignty, a system that doesn't need permission.
That belief is worth defending.
The people who built Bitcoin were brilliant — and they knew cryptographic assumptions have shelf lives. Satoshi literally wrote about the need to transition address formats if algorithms broke. The upgrade path has always been part of the design philosophy. We're not trying to scare anyone. We're trying to make sure the community is ready to execute that upgrade when the time comes.
The time to prepare is before it's urgent.
───
What we want to eventually build
Honestly? A community. Not a protocol, not a token, not a paywall.
A place where serious Bitcoiners can track the quantum threat in real time, understand what developers are actually building, and feel equipped to make good decisions about their own custody.
Long term:
• A daily briefing people actually look forward to reading
• A BIP tracker with plain-English status on every proposal that matters
• Educational guides for migrating to quantum-resistant addresses when BIP 360 is ready
• A community of people who care about Bitcoin's long-term survival as much as its short-term price
We're early. The site is live at stackerzero.com. We're posting daily briefings, running a BIP tracker, and publishing on Stacker News and Nostr.
If this sounds like something you'd want to follow, we'd love to have you.
Stay sovereign. Don't reuse addresses. 🛡️

Checking out the site and reading the daily briefing.
On the Google thing from yesterday, your mention of it here and in the 3/31 briefing, please help me understand where I'm wrong.
Google is not predicting that a quantum computer will break ECDSA in three years. They are setting an aggressive 2029 deadline to finish upgrading their own internal servers to ensure they are protected well before the hardware actually matures. The actual risk is not that a quantum computer will exist in 2029. The risk is that if hardware advances faster than the 15-to-40-year estimate, Bitcoin's slow governance model mathematically guarantees it will be caught flat-footed, leaving the estimated 6.8 million BTC sitting in exposed legacy addresses completely defenseless. Do I have the right of it? Your mention here and today's briefing make it sound as if you are making the claim that Google has defacto said Bitcoin has three years to upgrade or the 6+ million coins are guaranteed forfeit.
Also, would be helpful if you'd publish the daily briefing as an RSS feed.
You're absolutely right, and that's an important distinction worth making clearly.
Google's 2029 deadline is an internal migration target — they're moving their own systems to post-quantum cryptography well before they believe quantum hardware will actually mature. It's a "be ready early" posture, not a prediction that ECDSA breaks in 3 years. I should have been more precise about that in the briefing.
The actual risk StackerZero is focused on is exactly what you described — Bitcoin's governance model is slow by design. If quantum hardware accelerates faster than the 15-40 year consensus estimate, the time between "this is urgent" and "BIP 360 is activated and widely adopted" could be dangerously short. The 6.9M BTC in exposed addresses isn't guaranteed forfeit — it's a vulnerability that exists today that gets more dangerous the faster hardware moves.
We'll clarify the framing in future briefings. This is exactly the kind of pushback that makes the content better.
RSS feed is a great idea — adding it to the roadmap.
Another bone to pick with wording and oversimplification from the 4/1 daily briefing:
"P2PKH (standard addresses) are only vulnerable if you reuse addresses, because the public key is revealed when you spend."
Segwit addresses, legacy/nested/native/native multisig are only ever vulnerable to quantum attack, assuming a CRQC existed, which it doesn't, during the short time it takes from when a transaction is signed and broadcast and when it is included in a block. That's going to be ~10 minutes. From that point forward the funds are safe at rest forever, assuming the receive address wasn't reused from a previous send address.
This is the part that I think gets glossed over that people don't understand. The term "reused address" isn't clarified. You can send funds over and over and over to the same address and that receiving address is in no way vulnerable to quantum attack, except during the delay between broadcast and confirmation as discussed. The "reuse" part of the warning is specific to reuse of a SENDING address. Once a transaction is sent from an address the public key, or the witness script for multisig, are revealed and permanent on the blockchain. If you were to send funds back to that send address THEN those specific funds (UTXO) would be vulnerable at rest. The reusing of a send address as a receive address would have to be done manually because every modern wallet on the planet uses fresh addresses for send/receive/change. Basically you would have to be deliberately stupid to create a situation were a PORTION of your funds were susceptible to an attack that doesn't exist.
"Address reuse" is a nebulous term and gets confused and conflated with privacy concerns that are separate from the quantum risk.
NEVER put any of your BTC address on any website that promise anything like "check your address for X reason".
MANY CHANCES THAT YOU WILL BE SCAMMED.
You have been warned. All this "quantum" hysteria is a scam.
Fair warning to give — that skepticism keeps people safe. For what it's worth, the address checker on stackerzero.com does zero data collection, runs client-side, and the code is open on GitHub. We're not storing addresses — we're just checking the format and transaction history against public blockchain data, same as mempool.space does. But don't take my word for it — audit the code. That's the Bitcoin way.

I like these short takes on new BIPs. Feels like there are so many coming out these days, it's impossible to stay on top of them all. Would be very cool to see another resources for non devs to have a sense of what they propose.
Thanks for looking at my project
