1. What Is Plasma
Plasma is an early layer-2 scaling framework that moves computation and state off-chain into child chains, with periodic commitments posted to the main chain and fraud-proof-based exits.
2. How It Works
A Plasma chain runs its own consensus and periodically submits block commitments (Merkle roots) to the main chain. Users deposit assets into the Plasma chain and can exit by submitting proof of ownership during a challenge window; fraud proofs challenge invalid exits. Plasma's design was limited by data-availability problems — exits require data users may not have.
3. Why It Matters
Plasma was a foundational scaling research direction (proposed by Vitalik Buterin and Joseph Poon, 2017) that influenced rollups. Its insights about commitments, exits, and fraud proofs shaped modern optimistic rollups, though Plasma itself was largely superseded.
4. Key Facts
- Plasma Cash and Plasma MVP were key variants
- Exit games were complex and vulnerable without data availability
- Rollups solved Plasma's data problem by posting data on L1
- Plasma remains relevant to discussions of L2 security models
5. Related Concepts
