Is Know Your Developer a Supply Chain Solution?

The financial industry has a concept of “know your customer” to prevent financial fraud. The concept is that fraudsters do not want transactions linked back to their identity.

Hello World

It seems like every blog needs to start with an introduction, so here’s mine. I’m Brandon Mitchell, a currently semi-retired OSS developer.
