Brothers,
Today’s news, you might not have taken it seriously:
**Blockstream researcher proposed a hash-based post-quantum signature scheme,
Used to protect Bitcoin in the quantum era.**
Many people see 'hash' and 'post-quantum' and directly skip it,
But I tell you:
**This is one of the most important foundational discussions about Bitcoin in the past decade.
Its level is higher than ETFs, whales, and halving.**
Because this is not about price.
This is survival.
**What exactly is a 'quantum threat'?
In a word:
Quantum computers can directly open Satoshi's wallet.**
Do you know, bro?
The old Bitcoin address (P2PK) has a fatal weakness:
Public key exposure = equivalent to having no private key in front of quantum computers.
Blockstream researchers have calculated:
→ BTC wallets created before 2012,
→ Most still use the old public key exposure format,
→ The total value is about $600 billion,
→ Including the $98 billion BTC in Satoshi's hands.
What does it mean?
Very simple:
**If quantum computers transition to 'large-scale effective operation',
Old wallets will be emptied within hours.**
This is not FUD.
This is mathematics.
And you thought quantum computers are still far away?
Wrong.
The current performance of quantum chips is exponentially improving.
No one dared to think about 100 qubit five years ago.
It has now broken through the 1,000 qubit prototype.
Google, IBM, and national laboratories are all in the race.
What is truly dangerous is:
**Quantum breakthroughs will not give you advance notice,
It will only happen suddenly one day.**
On that day, Bitcoin's price did not drop, but was:
👉 Direct panic collapse
👉 All old addresses have been emptied
👉 Global on-chain security will be rewritten
👉 Stablecoin panic
👉 All cryptographic products relying on private key security will be entirely reconstructed
This is why the core team of Bitcoin has started to lay out in advance.
**Two, why is Blockstream's solution so important?
Because it for the first time makes BTC possibly 'quantum invulnerable'.**
There are various routes for post-quantum cryptography:
Based on lattice
Based on hash
Based on coding
Based on the homogeneity hypothesis
Based on mathematical problems
But what can actually be realistically used and implemented in the Bitcoin system,
Basically only:
Based on hash-based signature schemes.
The reason is simple:
✔ Fast
✔ The concept is simple
✔ Compatible with Bitcoin's existing structure
✔ Easy to audit
✔ Security assumptions are consistent with Bitcoin itself
In other words:
**The future 'quantum immunity upgrade' of Bitcoin,
For the first time, there is a feasible path technically.**
It's like:
It turns out Bitcoin stands on the edge of a cliff,
For the first time, someone is telling you:
'Bro, actually, a bridge can be built here.'
Three, why does only Bitcoin need quantum immunity, while Ethereum does not?
This sentence is critical.
Because Bitcoin's 'immutability is stronger than functionality.'
The Bitcoin protocol is unwilling:
Change rules
Signature adjustment
Change algorithm
Go for soft forks
But Ethereum can:
EIP
Rollup
Account Abstraction
Easily upgradeable to a post-quantum structure
This is why the quantum threat poses a far greater danger to BTC than to ETH.
And the development principle of BTC is:
👉 'If it can be unchanged, it should be unchanged'
👉 'If it can be patched, don’t reconstruct'
👉 'Can soft fork, don’t hard fork'
So the difficulty of BTC's quantum upgrade = the highest in the entire industry.
That's why the solution proposed by Blockstream is so critical.
This is one of the most difficult and important technical discussions since BTC's inception.
**Four, you may not know, bro:
Once BTC truly enters the 'quantum immunity era', the crypto market will undergo significant changes**
I will show you the chain reaction of the future:
① BTC will welcome a massive 'institutional accumulation'
Because:
→ Quantum risk alleviation
→ Sovereign funds are more at ease
→ Pensions are more willing to invest
→ Large insurance institutions are more willing to hold
→ Long-term holdings are not afraid of address leaks
This is called risk discount removal.
BTC's 'security premium' will become that which ETH cannot compare.
② All old BTC wallets must migrate; there will be an 'epic capital movement day' on-chain.
Will happen:
Whale migration
OG migration
Early address migration
Institutional custody address migration
Bro, do you know what this means for the market?
→ The old BTC era is completely over
→ The new BTC on-chain structure will refresh
→ The on-chain UTXO age distribution will be rewritten
→ Transaction volume will refresh historical highs
→ Price fluctuations will be extreme
→ All old funds are revived
This wave of migration can bring far more on-chain heat than halving.
③ ETH, SOL, and L2 will all be pushed into the post-quantum track
Because once BTC starts:
→ The entire Web3 industry must have quantum immunity
→ Wallets must be upgraded
→ MPC must be upgraded
→ zk-rollup must be upgraded
→ Cross-chain bridges must be upgraded
→ Stablecoin custody must be upgraded
This will be a major upgrade cycle across the entire industry comparable to 2016-2020.
④ The post-quantum track may become a new narrative worth tens of billions
Similar tracks:
AI
RWA
DePIN
GameFi
L2
Post-quantum is the next major narrative.
Because it is not 'innovation,'
It is 'survival'.
**Five, the most concerning question for bros has arrived:
Is the quantum risk imminent now?**
I give you the most authentic assessment:
In the short term, it won't kill Bitcoin, but within 10-20 years, it will definitely become a decisive issue.
The conditions under which quantum computers can truly threaten BTC:
Stable high qubit quantity
Fault tolerance capability enhancement
Noise elimination
Scalable architecture
Commercial production
But once breakthroughs occur in several key technical bottlenecks, the growth rate will be:
→ Exponential
→ Continuity
→ Irreversible
Faster than the growth of the crypto industry.
So the current layout is the right direction.
Six, my summary in one sentence:
Bro, listen carefully.
The real enemies of Bitcoin are not Ethereum, not the Federal Reserve, but quantum computers.
Today Blockstream proposed a solution,
Not for the current price,
But for:
Protect the scarcity of 21M BTC
Protect old addresses from being pried open by quantum
Make BTC eligible to become the reserve asset of the 21st century
Let global institutions use BTC with peace of mind
Let the crypto industry enter the next civilization cycle
The reason this is important is because:
**If Bitcoin cannot survive in the quantum era, then it can never become the ultimate asset.
And now, for the first time, it has the potential to become the 'ultimate asset.'**

Brothers:
Do you think BTC will hard fork for the quantum era?
Will it still go for soft forks and account migration? $BTC
