Privacy concerns with consensus-based blockchain transactions

IE Ibby EL-Serafy Public Seen by 306

There are potential privacy concerns in the use of a publicly accessible blockchain tied to individuals' identities. This may be a bigger concern if transactions are "consensus based" since this would require details of the transaction (as in, what was traded for what) be public - with other systems these details may be encrypted, or not even present.

Potential concerns:
1. Could reveal information the parties of the transaction would not like to publicly known (whatever the reason)
2. The use of the blockchain in a system of governance in a country where this is against the law

Would you define "blockchain" for me?

I am currently writing a short thing to explain it, and potentially making a video, but in short:

A blockchain is a decentralised method of book-keeping. It can keep records of transactions, ownership, marriage, etc, but without the need for a centralised organisation to verify the trust of these records.

I agree there could potentially be privacy concerns. People's location at a time could be made public, and there are many people who need to not be find-able.

But I don't think these concerns would be worse than with our current Facebook and rota system.
