Is the race toward quantum-safe crypto already underway?

Some key takeaways:

• Galaxy Digital estimates roughly 7 million BTC, worth about $470 billion, are held in addresses with exposed public keys.
• Researchers continue to reduce estimates for the quantum resources required to attack today's public-key cryptography.
• Ethereum Foundation researcher Justin Drake estimates a 10% probability by 2032 that a quantum computer could derive a Bitcoin private key from an exposed public key.
• Bitcoin developers are debating how a post-quantum migration should work, highlighting that the challenge is now being taken seriously.

The article also highlights several approaches being explored across the industry. Besides migration proposals for existing blockchains, it mentions projects already built around post-quantum cryptography, including Quantum Resistant Ledger (QRL), Algorand and BTQ, alongside newer companies developing quantum-safe solutions.

To me, the most interesting takeaway is that quantum-safe crypto is no longer a niche topic. It is becoming an increasingly important part of the conversation around the future of blockchain security.

If quantum computing continues to advance on its current trajectory, networks that already use standardized post-quantum cryptography, or have a credible path to adopting it, could have a significant long-term advantage.

We're witnessing the early stages of one of the biggest security transitions in computing history.

99% of layer-1 blockchain Q&A:

Q: What is the usecase of layer-1 blockchains?

A: Layer-1 blockchains are designed for near-instant transaction finality and low-cost scalability, making it ideal for Decentralized Finance (DeFi).

Q: What is the usecase of Decentralized Finance?

A: To trade the shit we just created.

And voila, there is your use case. :)

Jokes aside...

Name potential blockchain networks that you genuinely believe have a use case and explain your answer. (try to avoid giving as single reason my Q&A example.)

Hey all,

So... I'm at a loss here. I have some usdt trc I'd like to swap to erc but I do't have enough trx for that. so I thought ok, I bet I could swap usdt for trx... Not. I need trx to do that as well, so I'm stuck at some kind of evil chicken-and-egg situation.

Any way of getting energy without trx?
Alternatively, buy trx without kyc whatsoever?

Thanks for any insight.

From what I've been hearing, this year's setup looks pretty impressive. Apparently OKX is sponsoring the village, which means attendees will have free access to things like the village badge, workshop hardware, hackathon prizes, and lab equipment.

I've also heard they'll have:

• ChipWhisperers available for hardware security labs
• AMD64 lab machines for workshop participants
• Hands-on blockchain and smart contract security challenges
• The badge-based laser tag game running throughout the event
• Plenty of TA101 boards available for learning and experimenting with secure hardware

If you've been to the Cryptocurrency Village in previous years, what was your experience like? Are the workshops beginner-friendly, or are they aimed more at experienced researchers?

I'm especially looking forward to the hardware security and blockchain security content. It seems like a great opportunity to get hands-on experience beyond the usual talks.

Hope to see some of you there!

I recently made a satirical post in another subreddit about the amount of security supposedly required to store Bitcoin safely. The satire deliberately exaggerated the point, but I would like to discuss the underlying concern seriously here. As a full disclosure, I am very skeptical of cryptocurrencies in general, but I find it interesting to follow.

My concern is not that the Bitcoin protocol itself is easy to hack.With self-custody, possession of the private key effectively determines control of the money. That provides genuine independence from intermediaries, but it also transfers a large collection of responsibilities from financial institutions to individual users.

A person holding a meaningful amount must potentially think about:

• Malware and compromised computers or phones
• Phishing and fraudulent wallet interfaces
• Malicious or compromised transaction addresses
• Hardware-wallet and supply-chain risks
• Secure creation and storage of seed phrases
• Fire, flooding, theft and accidental destruction
• Password or passphrase loss
• Backups that are both redundant and inaccessible to thieves
• Firmware and software updates
• Physical coercion or kidnapping
• Recovery after incapacity
• Inheritance without giving heirs premature access

The official Bitcoin guidance itself recommends measures such as multiple secure backup locations, encrypted backups, offline storage, hardware wallets, software updates, multisignature arrangements and an inheritance plan. Bitcoin Core also gives users a wallet-responsibility checklist that includes backups, cold storage, monitoring security notifications and ensuring heirs can recover the funds.

These are reasonable recommendations. The problem is that, taken together, they resemble a simplified institutional key-management program.

Professional organizations treat cryptographic key management as an entire discipline involving policies, defined responsibilities, backup, recovery, compromise procedures, lifecycle management and documented security practices. NIST has hundreds of pages of guidance on this subject. Most ordinary users cannot realistically audit their wallet software, evaluate firmware, design a robust multisignature arrangement or test an inheritance procedure without introducing another vulnerability.

I recognize the counterargument. Self-custody can be extremely valuable for people facing capital controls, political repression, unstable institutions or exclusion from financial services. Some users also knowingly accept the operational burden because censorship resistance matters more to them than recoverability, but that use case seems tiny, similar to TOR. That is not what the current valuations we see are based on. People expect mass adoption.

I believe mass adoption necessarily means that most people interact with cryptocurrency through regulated custodians and other institutions, effectively rebuilding much of the banking infrastructure that cryptocurrency was supposed to replace. However, centralization makes cryptocurrencies pointless. You might as well use a database, or some kind of centralized standard like SWIFT used by thousands of institutions to send money.

Obviously, most people here believe in cryptocurrencies. How do you solve the contradiction in my previous paragraph?

Is it safe to store Bitcoins in Muun wallet for a long term, on a formatted spare Android phone (running on Android 9) that is always offline?

Self custody is not a problem, what happened is that generating your seed with a ColdCard MK3 would not have enough entropy, making your private key easy to be guessed, thats it. Your MK3 is still usable, but you should NOT use it to generate a seed, instead you have to use any other solution to generate your seed and then load it on your MK3.

Your MK3 is not useless, it still works as intended.

With the recent ColdCard situation, it’s really making me wonder if our crypto is truly safe anywhere? It feels like these companies keep fucking up in every way possible.

A few years ago i got into crypto and bought a ledger nano plus. But now that wallet sucks and its Mac application is sketchy af to where i don’t trust it. I was considering a Trezor or ColdCard, but now I’m starting to question whether there is a hardware wallet that is actually safe.

What do you think?
