</div>
James Vertisan (born James Browning in March 1970), is a software entrepreneur, architect, and coder. He is also a published author and life member of Mensa.
## Business Career
James' business career began when he started his first software company, AB Software Designs, in May 1989. He had been actively coding since December 1982, but the idea of a software company blossomed out of a high school extracurricular project at the end of his senior year. The project was overhauling and improving the software that ran the MSAD 71 public school system in 1989.

### Cryptographic Proof
There's no definitive need or desire to offer indisputable cryptographic proof of the Satoshi identity, because there is no bulletproof way to prove it 100.0%. Any validation methods are susceptible to a small percentage of edge cases where the validation could be disputed.
Regardless... following is a message signed with one of Satoshi's many PGP private keys:
###### OpenPGP public/private key pair - 0x64B1509ED4DFB4EF
