                "Pay To Identity" — a proposed use of OP_CHECKDATASIG
              
          

        

      

        

  

      

    
"Pay To Identity" — a proposed use of OP_CHECKDATASIG


Dr. Mark B. Lundeberg, 2018 September 6
bitcoincash:qqy9myvyt7qffgye5a2mn2vn8ry95qm6asy40ptgx2


A mechanism where a Bitcoin Cash payment is made to a personally identifying string (real name, email address, social media handle, etc.) instead of directly to a cryptographic key. The payment can only be claimed by the recipient if they generate a public key and get it certified by an identity verifier. This certification signature is confirmed in script via the new opcode OP_CHECKDATASIG.


Characteristics:


    

  • Pay anyone, right now -- recipient doesn't need to have any cryptographic keys nor do they even need a phone/computer. (They only need these to claim the funds later.)
    •

BLAKE2


    

  • 

    BLAKE2 is an improved version of the SHA-3 finalist BLAKE, and was designed by a team of experts in cryptanalysis, implementation, and cryptographic engineering; namely Jean-Philippe Aumasson, Samuel Neves, Zooko Wilcox-O'Hearn and Christian Winnerlein.
    

    • 

  • 

    BLAKE2s (the one checksum currently uses) computes a message digest that is 256 bits long, and represented as a 64-character hexadecimal number, e.g.   4264cb256d94533b6e152da59256638bc6adfda3efc5550d7607d4e6e45592fc.
    

    • 



Types


    

  • BLAKE2b (or just BLAKE2) is optimized for 64-bit platforms and produces digests of any size between 1 and 64 bytes.
    •

Distribution Detection


I am working on adding support for building and distributing (via PyPI) Python Wheels with C Extensions to the Python wheel and pip packages. The discussion on Distutils-SIG continues, but I believe it is fairly certain that some effort to correctly identify Linux distributions will need to be made. I've begun efforts to add this support to wheel.


How you can help


If you have a Linux distribution or version of a listed distribution not in this gist, or one of the ones I have not directly verified, I could use the following:


    

  • The contents of /etc/os-release, if it exists
    •
