Post-quantum encryption sounds like science fiction. It isn't. And if you use any messaging app today, you need to understand what's coming.
How does current encryption work?
Most encryption today including the kind used by Signal, WhatsApp, and iMessage is based on a simple mathematical principle:
Some calculations are easy to do, but nearly impossible to reverse. Multiplying two large prime numbers takes a second. Finding which two primes were multiplied to get a large number takes conventional computers thousands of years. That's the lock. Your private messages depend on it.
The quantum problem
Quantum computers don't work like conventional computers. They don't try every possibility one by one. They evaluate many possibilities simultaneously through a principle called superposition. In 1994, mathematician Peter Shor proved that a sufficiently powerful quantum computer could break the math behind today's most common encryption not in thousands of years, but in hours. That computer doesn't exist yet at scale. But it's being built.
Harvest now, decrypt later
Here's the part most people miss.
Governments and intelligence agencies don't need to break encryption today. They're collecting encrypted data now storing it waiting for quantum computing to mature.
Your messages sent in 2024. Your financial data from 2025. Everything encrypted today could become readable tomorrow. This strategy is called "harvest now, decrypt later." It's already happening.
The post-quantum response
Post-quantum cryptography is a new generation of algorithms designed to resist quantum attacks. In 2024, NIST, the US National Institute of Standards and Technology officially standardized the first post-quantum algorithms. One of them is CRYSTALS-Kyber, designed specifically for secure key exchange against quantum threats.
This isn't theoretical anymore. It's the new standard.
Liberdus as a solution
Most messaging apps are still running on encryption that quantum computers will eventually break. Signal, WhatsApp, Telegram. Their encryption is strong against today's threats. Against tomorrow's, it's a different conversation and none of them have shipped post-quantum protection yet. @liberdus combines CRYSTALS-Kyber for key exchange with AES-256 for symmetric encryption by default, for every message, today. Not on the roadmap. In the protocol.
The quantum threat isn't here yet.
But the data being collected today will still exist when it arrives. The time to switch to quantum-resistant communication isn't when the threat is real. It's before.

✍️Taking steps to protect the future of Bitcoin, they announced the establishment of the Bitcoin Quantum Readiness Initiative, allocating up to $5 million USD (approximately 170 million THB) in funding to developers to accelerate the development of technologies that will better protect the Bitcoin network from future threats from quantum computers.
While there are currently no quantum computers powerful enough to crack Bitcoin's encryption, many experts believe that preparing today is crucial, as upgrading the Bitcoin network will take several years, including development, testing, and gaining consensus from the global community.
The funding will focus on developing Post-Quantum Cryptography, a next-generation encryption system capable of withstanding quantum computer attacks, as well as creating tools for migrating coins to wallets that support the new standards and conducting thorough code security checks to ensure the safest possible transition.
Galaxy Digital states that the real challenge may not be the arrival of quantum computers, but rather whether the Bitcoin community can collaborate to upgrade the network in a timely manner. Since Bitcoin lacks a central organization capable of dictating system updates, every change requires approval from developers, miners, wallet providers, and users worldwide.
Another important factor is that NIST's post-quantum cryptography standards are beginning to be defined, leading the global technology and financial industries to plan for a transition to a new form of security. The crypto industry is also increasingly focusing on this issue.
For investors, this news is a positive long-term sign, reflecting that leading companies in the industry are investing in securing Bitcoin proactively, even if threats aren't imminent. Preparing in advance is better than waiting to fix damage after it has occurred.
Ultimately, Bitcoin's future strength may not depend solely on reaching new all-time highs, but also on the community's ability to develop and adapt to ever-changing technology. A successful upgrade to the post-quantum era will boost investor and institutional confidence worldwide in the long term.
