Translucent Databases[1] is not the same thing at all. The approach they are using requires the person doing the querying to have the same encryption key that the data is encrypted with (eg, they recommend hashing data then querying with the hashed data[2]). This is a great technique that improves security. But is isn't the same as zero-knowledge techniques which are comparatively new. The maths for them first developed in the mid-to-late 1980s, but zkSNARK (which made it useful in computer science) wasn't developed until 2012[3] [1] https://www.wayner.org/node/15 https://www.wayner.org/node/15 [2] https://www.researchgate.net/publication/301174908_Translucent_Databases https://www.researchgate.net/publication/301174908_Transluce...
