 ## Probabilistic Read Permissions
 
-Bloom filters are bit arrays that encode keys `n` times. They are represented by a base64 encoded tag value with the `n` as the third element. 
+Probabilistic permissions use bloom filters that include a set of pubkeys. They are represented by a colon-separated value with: 
+1. the size of the bit array
+2. the number of hashing rounds used by the filter 
+3. the bit array in Base64.
 
 ```json
-["prp", "<bit size>:<rounds>:<base64>"]
+["prp", "<BitArray Size>:<Rounds>:<base64>"]
 ```
 
 Bloom filters MUST use `SHA-256` functions of the key + iterating index as the psedocode below:
