The five OPI submetrics
OPI.AP — Active participant breadth · 25%
Measures the breadth, diversity and retention of economically active participants while accounting for concentration and the limits of address-based identity.
OPI.SP — Security participation · 20%
Measures how broadly effective security participation is distributed. The evidence adapts to consensus architecture: stake and validator control for proof of stake, work and mining control for proof of work, or equivalent control structures for other architectures.
OPI.GP — Governance participation · 15%
Measures meaningful involvement in shared decision-making. Formal token voting is not required; the adapter measures the network's actual governance process and lowers confidence where authority cannot be observed clearly.
OPI.DP — Developer participation · 20%
Measures sustained productive development rather than raw commit counts, including active contributors, retention, reviewed changes, releases, maintenance and independent organisations.
OPI.DR — Distribution and retention · 20%
Measures whether participation persists through time and avoids excessive concentration among users, validators, delegates, developers or applications.
What a high OPI means
A high OPI indicates a network is actively used and maintained by a broad, persistent set of productive participants. It does not by itself establish security, liquidity quality, real-world adoption or resilience; those are measured by other Voxonomics parent indices.
Architecture-specific evidence, universal meaning
Voxonomics does not force every network into the same raw field. A proof-of-work chain and a proof-of-stake chain expose security participation differently. OPI keeps the economic meaning constant while chain-specific adapters obtain the relevant evidence.
Publication rule: a documented measurement is not automatically an official OPI score. Evidence coverage, confidence, adapter status and the Edition 3.1 publication rules still apply.
