Blockchain is specifically designed to secure decentralized applications. > In fact, it adds traceability. And data stored in it can never be deleted. Just to name a few issues. These aren't issues, these are part of the security model. Traceability is fine here because everything is pseudonymous, if you want to avoid that use a chain that has untraceable transactions with zero knowledge proofs (zero traceability). > And data stored in it can never be deleted. Just to name a few issues. Storing data on blockchain is extremely expensive. Only hashes are stored on chain, not the data itself. Hashes are much different from encryption because they're irreversible.
