"And of his fullness have all we received, and grace for grace."— John 1:16
This relay bestows an overwhelming outpouring of gift wraps (NIP-59, kind 1059) upon any client that subscribes. Because a gift wrap cannot be identified as spam until after decryption — and decryption costs CPU time — a flood of gift wraps is a viable denial-of-service vector against Nostr clients. Grace exists to demonstrate this attack surface and measure how much grace a client can receive before it crashes or becomes unusable.
Each gift wrap is signed but contains random garbage inside — the outer seal is valid, the inner blessing is void. Your client must try to unwrap every single one.
This relay is a proof-of-concept for a NIP-59 spam attack. Subscribe with kinds: [1059]and the relay will flood your connection with gift wraps at ~100 events/sec. Clients cannot distinguish spam from legitimate DMs without decrypting each event. This is an unsolved problem in the Nostr protocol.
No souls have yet received Grace. The flock awaits.
