Blockchain networks develop quantum-resistant security measures

Major blockchain networks are exploring technical pathways to defend against future quantum computing threats.

TRON is currently testing post-quantum signature options, specifically Falcon-512 and ML-DSA-44, on its Nile testnet. While these signatures offer enhanced security against quantum attacks, they require significantly more data than current ECDSA signatures. Capacity models suggest this increased data usage could reduce transaction throughput; for instance, full ML-DSA usage could lower capacity to approximately 173 transactions per second (TPS). Implementation on the mainnet remains subject to network governance approval.

Bitcoin is also developing a roadmap for quantum resistance. Researchers are examining proposals such as BIP-360’s Pay-to-Merkle-Root (P2MR), which aims to limit public-key exposure by committing funds to a Merkle root, and Blockstream Research’s SHRINCS, which targets quantum-resistant signatures. The primary challenge for Bitcoin involves migrating funds to secure addresses without disrupting the network, as quantum computers using Shor’s algorithm could potentially derive private keys from visible public keys.
