Hedera Hashgraph is exploring the practical applications of post-quantum cryptography in the crypto ecosystem through a strategic partnership with SEALSQ. $HBAR, as the native token of the network, plays an important role in this collaboration. This cooperation demonstrates Hedera's forward-looking approach to addressing the threats of quantum computing — not only technological innovation but also a deep optimization of Web3 security infrastructure. Post-quantum security is gradually moving from theoretical to practical application, and such explorations set a benchmark for the entire industry.
