🚨 Google’s New Quantum Computing Just Put a Countdown on Every Blockchain.
Crypto is at an Existential Threat.
If you hold $BTC and $ETH, this thread is for you.
Only a few blockchains are built for post-quantum era.
Here’s who’s ready… and who isn’t.
🧵👇
1/ What’s happening?
Google just unveiled its new Quantum Computing power that is 13,000x faster than the best supercomputer in the world.
Quantum computers aren’t science fiction anymore.
Google, IBM, and China’s CAS have already achieved quantum advantage.
The crypto would collapse on itself.
2/ Blockchain Security rely on mainly two cryptographic tools:
•SHA-256: A hashing algorithm that secures block data and mining processes (notably in Bitcoin).
•ECDSA: The elliptic-curve digital signature algorithm that authenticates wallet transactions across nearly all major networks.
3/ Shor’s Algorithm is the ultimate quantum decryption tool, capable of dismantling ECDSA, the cryptographic system protecting your private keys, in seconds if sufficient quantum power exists.
That’s the looming threat to every traditional blockchain. ⚛️💥
4/ In Bitcoin for example, any wallet that’s made a transaction = exposed.
Once you send funds, your public key is on-chain.
A quantum computer could derive your private key from it.
There are over 1.9 million BTC (~$130B) sitting in exposed addresses.
5/ Which Crypto are Post-Quantum Ready?
Since the SHA-256 and ECDSA will easily be hacked through quantum computing, the one of few cryptographic tools for Post Quantum era is:
Ed25519: The Quantum Computer’s Kryptonite.
6/ $XRP uses ECDSA but also supports Ed25519, which makes it flexible to adopt post quantum era.
$XLM Uses Ed25519 for all signatures, making it more modern and efficient.
$HBAR uses Ed25519 signatures and is actively researching quantum-resistant algorithms for future network upgrades.
7/ Bitcoin and Ethereum aren’t exactly agile.
To make them quantum-secure, they would need:
• A major fork (hard or soft)
• Consensus across the global developer base
• Mass wallet upgrades
That’s a monumental challenge for any decentralized network.
8/ The Ticking Clock!
Experts estimate we could reach that point in 5-10 years.
This isn’t a crypto issue. It’s a national security issue. 🇺🇸⚛️
Ripple and Stellar have been quietly partnering with central banks and ISO-20022 institutions, the very entities already preparing for post-quantum systems.
9/ The Future Of Crypto.
Why do you think major financial infrastructures (SWIFT, BIS, ECB) are testing DLT systems like RippleNet, Hedera & Stellar?
Because they know what happens when quantum hits.
The next financial reset won’t come from regulation, it’ll come from physics. ⚛️
10/ The Post-Quantum Alliance
When quantum computing rewrites cryptography, only adaptive systems survive.
@DNAOnChain’s envisioned ZK-proof infrastructure might become the translator between classical and quantum-secure networks👇
xdna.dnaprotocol.org
zkbridge.dnaprotocol.org
11/ Quantum computing will break some chains and bless others.
When the reset comes, only those prepared for it will hold real value.
The survivors are already building in silence and their ledgers glow XRP blue, HBAR black and Stellar silver. ⚛️
