@satishluintel, I saw you asked about whether a blockchain could even be private. I would begin by asking you about your thoughts on IPFS. After that, I would ask you about your thoughts on Monero, Dash, Zcash, Verge, and BTCP. Generally, decentralization is mostly a goal. It might be more of a question of how decentralized a blockchain might be as opposed to something being absolutely centralized or not centralized. In other words, shades of gray. Perhaps, an allegedly private blockchain is simply able to make it harder to decode, to decrypt, to read, to see. I don't know enough to know if it is possible to have private blockchains. But we can at least try, right? Could Bit Torrent be private? If you are not downloading a file on Bit Torrent, perhaps that file is private to you in the sense that you cannot see it. Perhaps a blockchain could be like that. Perhaps, they could add features to block download from certain people. And if you can't download the data, then that might be a form of privacy. And on top of that, like I said earlier, perhaps nothing can be completely decentralized. Perhaps, your computer is a centralization of your brain. But that doesn't mean blockchains couldn't have some encryption. Perhaps, a blockchain could allow for peer to peer transactions. Perhaps, they could allow for encrypted data to go from my computer to your computer, through a blockchain. Perhaps, it could be like Proton Mail. Perhaps, a blockchain does not have to be completely distributed through decentralization where data is everywhere but instead something more like IPFS, like Bit Torrent.
