Hello everyone, I think this is my first email to this mailinglist so I will shortly introduce myself: I am Levin and the CEO of Coyno (www.coyno.com). Based in Berlin, mathematician. Bitcoiner since 2011. And now the reason for this email: Andreas (Schildbach) just released a new update of his wallet. It now provides an export functionality for the m/0' key in order to run read only copies on other devices. We already support the format on our website. Of course we would love for this to become standard. I also updated the Wiki article for Andreas' Wallet: https://en.bitcoin.it/wiki/Bitcoin_Wallet How do you like it? How does this format get standard? Shall I try to get a pull request to BIP32 passed? Cheers Levin
