Crypto is backed by the strength of the network and the algorithms that run the network.

As far as real-world value, all that's needed is for the value to be "bootstrapped" if you will. When ethereum was first released all it took was for someone to say "I'll buy your 1 Eth for X dollars" and boom the value of Eth is bootstrapped because we can attach the value of an Eth coin to a real world item.

After that bootstrapping, the value of today's Eth is governed by supply/demand and the value it had yesterday.
