HD Wallet Seed #4

Open ShepTanner opened 9 years ago

ShepTanner commented 9 years ago

I'm developing a server using bitcoin. How can I generate the addresses for my Airbitz wallet?

Great wallet!!! Keep up the good work.

swansontec commented 9 years ago

Our wallet generates a new address for every transaction. The HD wallet seed is used to set up the random number generator that does this. You can get full details on the algorithm in bip 32.

There are plenty of libraries that implement bip 32, including Python and Javascript. If you would like to see a brief example of how we do it, check out airbitz-keygen.sh, which uses the SX command-line tools.

What is the key derivation function employed? (BIP32 key path)

swansontec commented 8 years ago

We follow the wallet structure given in the BIP. So, it's master seed (m), then wallet 0 (m0), then chain 0 (m00), and finally the address index (m00n). We use one master seed per wallet, and we don't generate change addresses differently from regular addresses, so the two middle branches are always zero.
