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 | Casper the Friendly Finality Gadget |
|---|---|
| What the text proposes | A finality overlay. Validators cast two rounds of votes so that a chain of checkpoints becomes justified and then final. Equivocation can be slashed. The gadget does not, by itself, propose blocks. |
| Who may write | Vitalik Buterin and Virgil Griffith |
| What is settled | A proposal mechanism underneath. The gadget only finalises checkpoints of that proposal. |
| Load-bearing assumption | The gadget assumes a validator set and a way to slash. It does not define issuance, or a client. |
| What this library says afterwards | Finality lags the head of the chain on purpose. The head can still reorg before the checkpoint. |
