it's hard to decouple cryptography from derivatives & post-quantum purposes in a crypto cash system.. SHA2, SHA3, BLAKE2 are considered quantum-safe! So, the path to quantum resilience is fraught with challenges yet brimming with opportunity.

Suggested emergency plan in case 'SHA-256' is completely compromised!
Satoshi's sobering admonition serves as a stark reminder of the stakes at hand: the sanctity of Bitcoin's decentralized ethos hangs in the balance, poised on the precipice of 'quantum' oblivion…

"It may be possible to use bitcoin as a building-block in constructing an anonymous payment system; I'm skeptical, but what 'is' clear is the people currently advertising such systems haven't ever worked on traffic-analysis defeating protocols before. Any state-level adversary can link bitcoin back to the user's real-world identity or at least, real-world computer". ~Len Sassaman
"Bitcoin was the last thing on which I trusted blindly over the internet and If someday another Snowden will reveal that this really happens, I would just switch off my life from the Digital World." ~Aman Srivastava, #Bitcoin user of the Silk Road & other underground marketplaces.
Bitcoin would stay but Banks aren’t going anywhere…
Soon, AI will replace miners & deeply encrypt each hash calculation...

Quantum attacks on Bitcoin & how to protect against them.
Elliptic curve + Kyber… Apple has updated the iMessage protocol! Decidedly, a migration to quantum cryptography. 😌
56 days until the #Bitcoin halving!
When you suddenly start paying attention to bitcoin because the price has increased recently, don’t buy it; it’s about to CRASH💥 …. 😬

2 different phenomena with a messianic scope but little delayed according to the menu: One having fed 5,000 people with 5 loaves & 2 fish.
On the other hand, the contemporary has chosen to free over the world by offering a kit of 21M of tokens.
Not similar, but transfigured the game!
