**Status.** derived

This node is assembled mechanically from the 2 claims that carry the concept tag `proof-of-strong-collaboration`. It is a roster of what the corpus says under this term. It is **not** an adjudicated definition: no single statement here has been ruled canonical, and no first-appearance call has been made. Read the claims and judge for yourself.

## Every claim under this term

2 claims across 2 works, 2018 to 2025.

**2018**

- [3125827-016](https://wulfkaal.github.io/claims/3125827-016) [mechanism/argued] -- SPoS prevents the long range attack without token locking, because a false chain cannot be manufactured with more total validation than the real chain: votes are transactions moving validators' sem tokens under their public keys, so upvotes cannot be forged from existing tokens.
  > SPoS naturally prevents this attack without such locking, since a false chain cannot be manufactured with more total validation than the real chain.

**2025**

- [5225296-024](https://wulfkaal.github.io/claims/5225296-024) [mechanism/argued] -- Proof of Strong Collaboration substitutes verifiable participation for raw computational power, which reduces energy demand and rewards cooperative validator behavior rather than competitive hashing.
  > By prioritizing verifiable participation over raw computational power, PSC reduces energy demands, promotes cooperative validator behavior, and aligns with SPoS's sustainability objectives
