QoreChain has integrated a full stack of post-quantum cryptography based on NIST standards.
The Swiss blockchain network QoreChain has become one of the first public platforms to implement a full set of post-quantum cryptography algorithms approved by the U.S. National Institute of Standards and Technology (NIST) on its mainnet. This is a landmark event for the industry, as quantum threats are becoming increasingly tangible, and standardizing protection is a matter of time.
The key feature of the update is the implementation of three levels of protection at once: post-quantum digital signatures, key exchange protocols, and cryptographic hash functions. This comprehensive approach allows for the complete elimination of classical vulnerabilities associated with algorithms that could theoretically be broken by quantum computers.
On July 2, 2024, a test transfer of 1,000 QOR tokens was conducted on the network using the new stack. The transaction was successful, confirming the practical applicability of the solution. Developers emphasize that the main goal is protection against "harvest now, decrypt later" attacks, where attackers accumulate encrypted data hoping to decrypt it in the future using quantum computing.
This step is particularly important for long-term assets and confidential data that may remain relevant for decades. QoreChain, based in Switzerland, positions itself as a platform for corporate and government solutions where resistance to quantum threats is a critical factor.
Analytical commentary: Implementing a full stack of post-quantum cryptography on a public mainnet is not just a technical update but a strategic move. While most blockchains are still discussing the transition, QoreChain already provides a working solution. However, the main challenge remains—compatibility with existing protocols and the performance of such algorithms. If the network can maintain speed and low fees, this will become a significant competitive advantage in the enterprise blockchain market.
