Four documents, the same five questions.
No throughput league table and no yield. The cells are what this library is willing to say about the text.
| Question | Plasma: Scalable Autonomous Smart Contracts |
|---|---|
| What the text proposes | A 2017 construction for trees of child chains whose state commitments are posted to a parent chain, with exits so a user can leave if the child operator misbehaves. It is an ancestor of later rollup and validium designs, not a synonym for them. |
| Who may write | Joseph Poon and Vitalik Buterin |
| What is settled | The parent chain stores commitments, not every child transaction. |
| Load-bearing assumption | Plasma is not an optimistic rollup and not a zk-rollup. Those publish different data and different proofs. |
| What this library says afterwards | An exit game that users do not watch is not a security mechanism. It is a brochure. |
