Tok said cryptography 'wasn't a significant part' of cryptocurrencies. He didn't say they don't require them, so what was your point?
Can you (or Tok) point to a part of a cryptocurrency which
isn't cryptography?
the dev team, the website, any part of the wallet not doing a cryptographic function, the buyers, the masternode operators, the network transport, whatever isn't going into a cryptographic function.
...but i see what you mean. (I think) Tok was coming from a business point of view to try to rebalance the fact that on the XMR thread devs like Fluffy keep banging on about XMR is secure due to cryptographic proof and even sites examples like Tor and SSH - which forgets the other half of cryptocurrency security which is the implementation (heartbleed etc)
