Zcash has the best underlying privacy technology (zk-snark) and has good corporate backing. I think it will be a leader in getting Crypto accepted and used in business-to-business transactions; Augur is for prediction markets, Golem is for distributed computing.
All the major alts now have serious use cases, even if we are still early in their deployment. So the breezy dismissals of them by some Bitcoiners are now badly out of date. This isn't 2014. Bitcoin may remain a flagship, though that remains to be seen. But it is the flagship of a large and growing fleet, not a single boat.
Haha, well thanks for the education! I will consider myself part of the Bitcoiner crowd offering "breezy dismissals". But I'll now offer the respect deserved.
If Z cash could be used for business to business transactions, are we talking intercompany purchasing or true business to business?
Well, we're just talking my opinion and off-the-cuff comment, so it's not worth much. But my understanding of ZCash is that the protocol provides a more elegant privacy solution, while simultaneously allowing for auditability in a secure and controlled way. In other words, businesses or individuals can have private transactions (no competitors seeing everything they do financially on a public blockchain) without using mixers or additional complications. But on the flip side they can open their books to 3rd party auditors, government investigators, other businesses looking into investing in them and so on, in a way that allows the auditor to be sure they are getting the full picture without compromising the Zcash users security. That strikes me as the right mix to overcome some practical obstacles that have been holding back businesses from getting significantly involved with crypto for internal operations and B-2-B transactions.
