1. Three-Layer Architecture

Andromeda Core separates data acquisition, intelligence processing, and cryptographic anchoring into independent, auditable layers.

2. The TrustScore Formula

The reputation score combines five weighted dimensions with a behavioural confidence factor.

T = ( Σ wd · Sd ) · Cbehaviour2
d ∈ {tech, gov, com, rel, innov}

Dimensions

  • Tech – code & audits
  • Gov – voting & proposals
  • Com – community & mentoring
  • Rel – deadlines & promises
  • Innov – novel ideas & adoption

Key Insight

We square Cbehaviour so that suspicious accounts are penalised super‑linearly: a drop from 0.9 to 0.8 reduces the score by ~20%, not ~10%.

3. Asymmetric Exponential Decay

Each event's weight decays exponentially with time. Negative events decay 3× faster, allowing redemption but not forgetting.

Time (days) Weight Positive (λ=0.001) Negative (λ=0.003)
Sd = Σ wi · epos·Δt (positive)
λpos = 0.001 day-1
Sd = Σ wi · eneg·Δt (negative)
λneg = 0.003 day-1

4. Behavioural Confidence Factor

Three orthogonal anomaly signals are combined via a sigmoid to produce Cbehaviour ∈ [0,1].

Cbehaviour = σ( w1·s1 + w2·s2 + w3·s3 )

Anomaly Signals

  • s1 Temporal entropy – human activity shows natural randomness
  • s2 Network topology – genuine builders have diverse connections
  • s3 Impact/volume ratio – real work gets reused

5. Peer Endorsements (Cold Start)

New builders can receive endorsements, but anti‑collusion rules prevent abuse.

6. Merkle Verification & Escape Hatch

Every TrustScore batch is anchored with a Merkle root on Rootstock. A static HTML tool lets anyone verify scores locally. If Andromeda's agent stops, any indexer can rebuild the pipeline.
