Blockchain is a transparent and tamper-proof way of recording transactions, and it could potentially be used to record data about who has accessed certain information. However, it is important to note that blockchain is not a silver bullet solution, and there are some potential privacy concerns that need to be considered. For example, if data is stored on a public blockchain, then it may be possible for others to view the data and infer who has accessed it.

Q: Are blockchain users anonymous?

Q: Can everyone see transactions on blockchain?

Q: Is data on the blockchain private?
A: No, data on the blockchain is not private. All data on the blockchain is public and transparent.
Q: Who owns data in blockchain?
A: There is no one “owner” of data in a blockchain.
Instead, data in a blockchain is distributed across a network of computers, each of which stores a copy of the data.
This network is often referred to as a “peer-to-peer” or “P2P” network.
P2P networks are decentralized, meaning there is no central authority or server that controls the data.
Instead, the data is controlled by the network of computers that make up the blockchain.
