Building in Xcode requires you to build libtommath independently for both simulator, and device before you can test/build Breadcrumb.

At the moment we are doing private parent -> private child -> child pub key this requires us to keep the memory key stored to retrieve addresses, we should be using parent public key -> child public key derivation instead.

You can read about married wallets here - http://www.johba.de/married-wallets/

This will allow mobile wallets based on this library to be used in a way that they are resilient to phone loss. E.G. phone generates two keys, one to paper one for runtime and a third on a server. The server can then help the user recover and help them prevent their keys from being stolen in the case of a lost phone.

Hi,

The project below supports Pedersen commitments, borromean ring signatures, and ZK range proofs but compiles for x86_64 only.

https://github.com/ElementsProject/secp256k1-zkp.git

Whereas Breadcrumb supports all architectures including armv7,armv7s and arm64 but doesn't include support for Pedersen commitments, borromean ring signatures, and ZK range proofs. It would be great help if Breadcrumb can support this.

Also there is no autogen.sh or configure file present in Breadcrumb. Appreciate if you can help with this.

secp256k1_ecdh.h
improve ECDH header-doc

secp256k1_rangeproof.h
Pedersen commitments, borromean ring signatures, and ZK range proofs.

secp256k1_recovery.h
Comment copyediting.

secp256k1_schnorr.h
Change secp256k1_ec_pubkey_combine's count argument to size_t.

We should remove libbase58, and use our own implementation of base 58 encoding using libTomMath to reduce the number of dependencies.
