Bitcoin has just received the most controversial proposal in its history.
BIP-361 wants to freeze all coins that do not migrate to quantum-resistant addresses.
Deadline: 5 years.
Those who do not move will lose access by consensus of the network.
Why this matters:
→ More than 34% of all BTC have publicly exposed keys on-chain.
This is ~6.8 million BTC. Over $500 billion.
Vulnerable to theft if a sufficiently powerful quantum computer emerges.
→ Google published a timeline in March to migrate all its infrastructure to post-quantum encryption by 2029. It called the threat "closer than it seems."
→ No previous Bitcoin update has ever invalidated existing transactions. This would be the first.
The debate is philosophical:
In favor: "If we do not protect the network, the first functional quantum computer will steal hundreds of billions and destroy trust in Bitcoin."
Against: "A protocol freeze is confiscation. Today it is quantum. Tomorrow it is compliance with sanctions."
Jameson Lopp, co-author of BIP-361, summed it up better than anyone:
"I do not like this proposal. I wrote it because I like the alternative even less."
Bitcoin was designed to be immutable. BIP-361 asks to give that up to survive.
It is the first time the community needs to choose between foundational philosophy and practical survival.
And the answer will define what Bitcoin really is.
