[Bitcoin-development] Making the H in HD keychains useful

2014-03-01 Thread Eric Lombrozo
I've been trying to find ways to make HD keychain wallets (BIP0032) really usable from an application development perspective. I think we all know a number of solid use cases and possible applications for the D in HD, but nobody seems to have really found a way to make use of the H in a way

You can make the same argument against Bitcoin itself you know... A Bitmessage-like network would be trivial to front-run via a sybil attack. It's the fundemental problem with marketplaces - the data they're trying to publish has to be public. I don't see the Bitcoin analogy...

Another example use-case to back up devrandom's point is using a twitter handle as the merchant name. In that example, a 3rd party service hosts and signs the PaymentRequest, but when someone opens that PaymentRequest in their wallet, they should know that they are paying the specified twitter

[Bitcoin-development] Payment Protocol Hash Comments

2014-03-01 Thread Jeremy Spilman
From BIP70: If pki_type is x509+sha256, then the Payment message is hashed using the SHA256 algorithm to produce the message digest that is signed. If pki_type is x509+sha1, then the SHA1 algorithm is used. A couple minor comments; - I think it meant to say the field to be
