Is Bitcoin ready for a quantum world? Or not yet?
A debate is quietly heating up around two proposals: BIP-360 and BIP-361.
They’re not part of Bitcoin’s roadmap. They’re not approved.
But they raise questions that are hard to ignore.
Let’s break it down simply:
- BIP-360
A proposal to introduce quantum-resistant outputs.
The idea: prepare Bitcoin for a future where quantum computers could break current cryptography.
But:
- It doesn’t choose a final algorithm yet
- Post-quantum signatures are significantly larger than today’s
- That could mean fewer transactions per block, higher fees, heavier infrastructure
In short: a step toward security… with real trade-offs.
- BIP-361
A much more controversial idea.
It suggests that BTC sitting on old (non-upgraded) addresses could eventually be frozen if not migrated within a certain timeframe.
That raises obvious questions:
- What happens to lost coins?
- What happens to immutability?
- Who decides what is “inactive” or “non-compliant”?
So what’s really being debated? Just tech? Nope.
- Security vs scalability
- Preparation vs overreaction
- Immutability vs adaptability
- Freedom vs coordination
And maybe most importantly: How does Bitcoin evolve… without becoming something else?
It’s worth remembering:
- These are early-stage proposals
- No consensus exists
- Bitcoin upgrades historically take years (when they happen at all)
But the topic itself is interesting.
Because it forces a bigger question: What do we expect from a system designed to last decades… in a world that keeps changing faster?
Curious to hear your take:
Had you come across these proposals?
Do you think preparing for quantum threats should already be a priority?
Or is this a problem for a later stage?
No right answers here.
Just a conversation worth having. 🧡
