"Adding Support for Apple's Secure Enclave
We are extending our support for elliptic curve keys validation to include the secp256r1 curve. This is the standard created by NIST and used by Apple, Android, and many Smart Cards. Users will have the option to pick their curves (secp256k1, is used by Bitcoin and EOS by default) and can use both (r1 and k1) if they don't know which one to trust! The most important aspect of this is that it will give every cell phone user a hardware wallet with biometric 2nd factor validation.
Implementation is ongoing, but the design decision has been made and should make EOS.IO usable in far more environments."
