Randomized trial examines protocols for protecting personal data in blockchain, suggesting enhancements for quantum safety.

This research aims to address the security challenges posed by quantum computing to blockchain cryptosystems.
Examined classical cryptosystems (RSA, ECDSA) under quantum threat.
Proposed protocols for storing personal data in blockchain systems using smart contracts on Ethereum and Hyperledger Fabric.
Conducted comparative analysis of computational efficiency and overhead related to lattice cryptography.
Lattice cryptography provided high performance but resulted in a 50-fold increase in signature size.
Direct implementation of post-quantum cryptography in Layer 1 public networks is economically unfeasible.
Proposed a hybrid model and utilization of Layer 2 for enhancing quantum resistance.

Ishchukova et al. (2026) studied this question.
