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 | Hashcash: A Denial of Service Counter-Measure |
|---|---|
| What the text proposes | The client finds a partial hash collision. The server checks it cheaply. The stamp is the cost. |
| Who may write | Adam Back |
| What is settled | The puzzle is minted by the client, not by a miner race. |
| Load-bearing assumption | Hashcash is not Bitcoin. There is no longest chain in this note. |
| What this library says afterwards | A reading of the public paper. Not a copy, not a benchmark, and not a claim about any later network. |
