I am currently planing to develop a decentralized web to fight against government censorship.

As bitcoin's address / wallet model is quite successful, I would follow that model.
As far as I know the sha algorithm may not be safe enough for an address generator when the Quantum computing will soon come into use.

Is there any Quantum-safe Cryptography algorithm tested to be safe for an address generator and for data transmission?

It would be very nice to have an official node.js implementation.
