I am happy to give you an interview or provide you with a consultation.
I am very interested in innovative ways to secure property and personal interactions: all the way from cryptography to user interfaces. I am not interested in trading, mining or building exchanges.

CoreBitcoin, Bitcore and Bitcoin Core

In August 2013, 7 months ago, I have released my open source project CoreBitcoin. It is a Bitcoin framework designed with the excellent API and great documentation. Its name is chosen in line with Apple’s own frameworks: CoreFoundation, CoreGraphics, CoreAnimation. If Apple ever decides to integrate Bitcoin support right in their OS, they could simply take CoreBitcoin as is, since it matches their own high standards for framework API.

In January 2014, Bitpay released Node.js-based Bitcoin toolkit called “bitcore”.

In March 2014, developers of BitcoinQT (the “official” full node implementation) released version 0.9.0 and renamed the application in “Bitcoin Core”.

As of today, the amount of confusion around terms “core” and “bitcoin” was deliberately increased for no good reason.
