Chris Blask

In the early 1990s while trying to make it easier to get online, Chris Blask accidentally invented a firewall. When it turned out most folks couldn't use it without Network Address Translation, he fell into a mop closet and invented that with some colleagues, by carefully arranged random chance. More recently, while ranting about supply chain security in 2019 he tripped over a pile of digital chain, unintentionally placed there earlier for just that purpose, and found himself co-inventing Attestation Channels (Digital Bill of Materials) with Mehdi Entezari.
