Salus

The church houses the Salus Populi Romani, a Byzantine icon of the Virgin believed to have been made by St Luke the Evangelist and used by Jesuit orders all over the world.

Leicestershire-based Salus, the company which signed off the building, declined to comment.

The project's app - called Salus - is intended to work in real-time, using artificial intelligence to identify potential child sexual abuse material and stop users from seeing it.

“It’s a very odd transition, especially because I don’t know if the world was ready for the prominence of crypto,” Salus said.

Ben Salus, a Philly sports fan who has lost money in crypto, said he was uncomfortably surprised at the sudden increase of crypto-related signage around his favorite teams.
