PoSV

1 min read
Pronunciation
[pee-oh-ess-vee]
Analogy
PoSV is like a fitness tracker that scores you on both how much you invest and how often you exercise your investments.
Definition
An abbreviation for Proof-of-Stake Velocity, indicating the same consensus mechanism that factors both stake size and token activity.
Key Points Intro
PoSV maintains PoS properties plus:
Key Points

Dual metrics: Combines stake and activity.

Epoch-based recalculation: Scores update each epoch.

Sybil resistance: Requires both stake and transaction volume.

Economic balancing: Penalizes purely speculative holding.

Example
A blockchain wallet shows users their PoSV score, motivating them to both stake tokens and engage in network governance to maximize rewards.
Technical Deep Dive
Validators register stake deposits on-chain. A separate activity oracle tallies outgoing transactions per validator. At epoch boundaries, a smart contract computes new validator weights and updates the random beacon for block proposer selection.
Security Warning
Oracles tracking activity must be tamper‑proof; manipulated metrics can skew election fairness.
Caveat
Requires additional on-chain or off-chain infrastructure to measure velocity reliably.
