# Step 3: Setup Compute Layer

## Preliminary Compute

We then run compute on this data set to produce a set of **localized interactions** **(or attestations)** per profile, whether those attestations are following one another, having a post be recasted/mirrored by someone else, commenting on one another's post, and so on. These interactions between each user is placed into a matrix, then **we keep only the non-zero cells** in the matrix to then run the EigenTrust algorithm to see which relationship is stronger between one profile to another. The algorithm is now ready.
