One way to address the problem of data privacy in public blockchains is by using technologies such as zero-knowledge proofs, homomorphic encryption, and secure multi-party computation. These techniques allow for secure transactions and data sharing on public blockchains without revealing sensitive information to unauthorized parties. Additionally, implementing privacy-focused protocols like zk-SNARKs (zero-knowledge succinct non-interactive arguments of knowledge) can help enhance the privacy and confidentiality of data on public blockchains.
