Excuse me, What is the difference between the algorithms that generate the address between different currencies? I will be looking forward to your reply，thanks!

There are different parameters for each network that set the encoding of addresses and keys. You can see an example of those parameters in bitcoinsj-extensions.js.

The underlying mechanism is ECDSA.

Note that ethereum and ripple have slightly different mechanisms for their addresses. The code for this is in index.js L826-841. But again it's all ECDSA underneath.
