According to Adam Back, FIPS 205's SLH-DSA stands out as the strongest post-quantum secure digital signature candidate currently available, despite its relatively large signature size (source: Adam Back on Twitter, June 3, 2025). He recommends integrating SLH-DSA into new blockchain address formats alongside Schnorr taproot to address concerns over premature quantum threats. This move is particularly relevant for traders and blockchain developers seeking robust quantum-resistant security. Adam Back also highlighted the potential for future enhancements through signature aggregation using STARKs, suggesting further efficiency improvements for high-volume blockchain applications (source: Adam Back on Twitter, June 3, 2025). These developments may have a significant impact on cryptocurrency trading by increasing long-term asset security and supporting advanced blockchain scalability.
