Cloudflare just announced: All platforms will complete #PQC upgrade by 2029.

This is not just empty talk. Google set the same deadline two weeks ago, and IBM plans to deliver the first fault-tolerant quantum computer Starling by 2029—three companies pushing toward the same goal, indicating this timeline is serious.
Why the urgency?
Because the barrier has collapsed.
In the past, everyone thought cracking elliptic curve encryption (ECDSA) required 9 million qubits, but the latest research drops that number to 10k—joint research by Google and Oratomic brought this figure down. 10k qubits is no longer science fiction.
What about 👀 Bitcoin?
Approximately 6.95 million BTC are stored in old wallets, with public keys exposed, including Satoshi’s. Last year, this was considered pretty far-fetched, but hearing about it in the past two months is no longer surprising—it's commonplace now.
Chaincode Labs estimates that BTC’s quantum-safe migration could take about 7 years—during the last Taproot upgrade, it took four years just from proposal to activation.
👀 Web2 giants: The 2029 deadline means full upgrade and free service for users.
BTC community: BIP-360 is still debating design principles, consensus is still far off.
Cloudflare, Google, IBM are accelerating, and $BTC ’s “quantum survival script” hasn’t even turned to page one yet.
