Blockchain has been acknowledged as a way to solve fair information practices, a set of principles relating to privacy practices and concerns for users. [5] Blockchain transactions allow users to control their data through private and public keys, allowing them to own it. [5] Third-party intermediaries are not allowed to misuse and obtain data. [5]
Keybase is a key directory that maps social media identities to encryption keys (including, but not limited to PGP keys) in a publicly auditable manner. [2] Additionally it offers an end-to-end encrypted chat and cloud storage system, [3] [4] called Keybase Chat and the Keybase Filesystem respectively.
For example, the Whale Optimization Algorithm (WOA), uses a method of secure key generation to ensure that information is shared securely through the blockchain technique. [26] The need to improve blockchain methods is becoming increasingly relevant as the global level of development increases and becomes more electronically dependent.
Attribute-based encryption is a generalisation of public-key encryption which enables fine grained access control of encrypted data using authorisation policies.The secret key of a user and the ciphertext are dependent upon attributes (e.g. their email address, the country in which they live, or the kind of subscription they have).
Crypto-shredding or crypto erase (cryptographic erasure) is the practice of rendering encrypted data unusable by deliberately deleting or overwriting the encryption keys: assuming the key is not later recovered and the encryption is not broken, the data should become irrecoverable, effectively permanently deleted or "shredded". [1]
A cryptographic key is called ephemeral if it is generated for each execution of a key establishment process. [1] In some cases ephemeral keys are used more than once, within a single session (e.g., in broadcast applications) where the sender generates only one ephemeral key pair per message and the private key is combined separately with each recipient's public key.

The private keys are often stored in a cryptocurrency wallet like the hardware wallet in the image. The synergy between HSMs and blockchain is mentioned in several papers, emphasizing their role in securing private keys and verifying identity, e.g. in contexts such as blockchain-driven mobility solutions.
