I see blockchain to be like a search engine in the future, encoded though, which makes it unique. Just like in visuals, we have google giving almost any kind of information once you search through it. Soon, apart from the legal profession, some fields that desire some secrecy would start looking at blockchain, like the medical field etc.
What kind of secrecy you are talking here? Blockchain is mainly a distributed ledger technology which doesn't really hide things. Instead it make things transparent by keeping all data in a chronological manner. Every time you need to add some more data, a block is created and stored in the record. There's no secrecy? Do you mean security here?
