### Configure Pool Authentication (NIP-42)

**Description:**
|
||||
- Sets a pool-wide private key used to sign NIP-42 `AUTH` responses.
|
||||
- Enables/disables NIP-42 handling for all relays in the pool.
|
||||
- Propagates auth-enabled state to existing relay connections.

unsigned char privkey[32];

### Logging Integration (Consumer-Controlled)
|
||||
|
||||
`nostr_core_lib` now supports a callback logging API so host applications can route library logs into their own logger and destination.
|
||||
|
||||
- API is exposed via [`nostr_core/nostr_log.h`](nostr_core/nostr_log.h)
|
||||
- Included automatically from [`nostr_core/nostr_core.h`](nostr_core/nostr_core.h)
|
||||
|
||||
```c
|
||||
#include "nostr_core/nostr_core.h"
|
||||
|
||||
static void my_log_cb(int level, const char* component, const char* message, void* user_data) {
|
||||
(void)user_data;
|
||||
fprintf(stderr, "[nostr][%s][%d] %s\n", component ? component : "unknown", level, message ? message : "");
|
||||
}
|
||||
|
||||
int main(void) {
|
||||
if (nostr_init() != NOSTR_SUCCESS) return 1;
|

|
||||
nostr_set_log_callback(my_log_cb, NULL);

/* ... your code ... */
|
||||
|
||||
nostr_cleanup();
|
||||
return 0;
|
||||
}
|
||||
```
|
||||
|
||||
#### Migration Notes
|
||||
|
||||
- Direct file logging to `debug.log` has been removed from websocket and NIP-13 internals.
|
||||
- To receive logs, register a callback with [`nostr_set_log_callback()`](nostr_core/nostr_log.h:24).
|
||||
- Use [`nostr_set_log_level()`](nostr_core/nostr_log.h:25) to reduce verbosity in production.

# Logging Delegation Plan for `nostr_core_lib`
|
||||
|
||||
## Objective
|
||||
|
||||
Refactor `nostr_core_lib` so it does not own log destinations such as `debug.log`, and instead emits logs through a consumer-provided callback. This allows host applications such as [`didactyl`](../README.md) to route all library logs into their own logging system with consistent formatting, level control, and file policy.
|
||||
|
||||
## Current State and Problem
|
||||
|
||||
The library currently writes directly to `debug.log` in multiple places:
|
||||
|
||||
- [`nostr_core_lib/nostr_websocket/nostr_websocket_openssl.c`](../nostr_websocket/nostr_websocket_openssl.c:1008)
|
||||
- [`nostr_core_lib/nostr_core/nip013.c`](../nostr_core/nip013.c:178)
|
||||
- [`nostr_core_lib/nostr_core/nip013.c`](../nostr_core/nip013.c:242)
|
||||
- [`nostr_core_lib/nostr_core/nip013.c`](../nostr_core/nip013.c:270)
|
||||
|
||||
This creates collisions with consumer logs when the host app also uses `debug.log` such as [`didactyl/src/debug.c`](../../src/debug.c:18).
|
||||
|
||||
## Target Design
|
||||
|
||||
Adopt a callback-based logging API inside `nostr_core_lib`:
|
||||
|
||||
1. Library owns no file handle for logs.
|
||||
2. Library emits structured log events by level and source.
|
||||
3. Consumer registers a callback once during startup.
|
||||
4. If no callback is set, logs are dropped by default.
|
||||
|
||||
### High-Level Flow
|
||||
|
||||
```mermaid
|
||||
flowchart TD
|
||||
A[nostr_core_lib internal code] --> B[nostr_log_emit level source message]
|
||||

||||

C -->|No| E[drop log event]
|
||||
D --> F[didactyl debug_log routing]
|
||||
F --> G[didactyl log file or stdout]
|
||||
```
|
||||
|
||||
## API Additions
|
||||
|
||||
Add a small public logging API in [`nostr_core_lib/nostr_core/nostr_core.h`](../nostr_core/nostr_core.h):
|
||||
|
||||
- `nostr_log_level_t` enum with levels compatible with host systems
|
||||
- `nostr_log_callback_t` callback type
|
||||
- `void nostr_set_log_callback(nostr_log_callback_t cb, void* user_data);`
|
||||
- `void nostr_set_log_level(nostr_log_level_t min_level);`
|
||||
|
||||
Recommended callback shape:
|
||||
|
||||
```c
|
||||
typedef void (*nostr_log_callback_t)(
|
||||
int level,
|
||||
const char* component,
|
||||
const char* message,
|
||||
void* user_data
|
||||
);
|
||||
```
|
||||
|
||||
Notes:
|
||||
- Keep ABI simple by formatting message inside the library before callback invocation.
|
||||
- Include `component` values such as `websocket` and `nip013`.
|
||||
|
||||
## Internal Implementation Plan
|
||||
|
||||
## Phase 1: Logging Core
|
||||
|
||||
1. Create `nostr_core_lib/nostr_core/nostr_log.h` and `nostr_core_lib/nostr_core/nostr_log.c`.
|
||||
2. Add internal singleton state:
|
||||
- callback pointer
|
||||
- callback user data
|
||||
- minimum log level
|
||||
3. Add internal helpers:
|
||||
- `nostr_log_emitf level component fmt ...`
|
||||
- stack buffer formatting with truncation safety
|
||||
4. Default behavior when no callback set: no-op.
|
||||
|
||||
## Phase 2: Replace File Logging in WebSocket Layer
|
||||
|
||||
1. Remove file-specific static globals from [`nostr_websocket_openssl.c`](../nostr_websocket/nostr_websocket_openssl.c:27).
|
||||
2. Remove `debug_log_init` and `debug_log_message` path at [`nostr_websocket_openssl.c`](../nostr_websocket/nostr_websocket_openssl.c:1005).
|
||||
3. Replace call sites:
|
||||
- outgoing frame logging near [`nostr_websocket_openssl.c`](../nostr_websocket/nostr_websocket_openssl.c:871)
|
||||
- incoming frame logging near [`nostr_websocket_openssl.c`](../nostr_websocket/nostr_websocket_openssl.c:964)
|
||||
4. Emit through `nostr_log_emitf` with component `websocket`.
|
||||
|
||||
## Phase 3: Replace File Logging in NIP-13
|
||||
|
||||
1. Replace `fopen`/`fprintf` blocks in [`nip013.c`](../nostr_core/nip013.c:178), [`nip013.c`](../nostr_core/nip013.c:242), and [`nip013.c`](../nostr_core/nip013.c:270).
|
||||
2. Emit equivalent debug lines via `nostr_log_emitf` with component `nip013`.
|
||||
3. Preserve existing compile-time verbosity guards if needed, but route output through callback.
|
||||
|
||||
## Phase 4: Wire Public API
|
||||
|
||||
1. Export new functions in [`nostr_core.h`](../nostr_core/nostr_core.h:1).
|
||||
2. Ensure object file inclusion in `nostr_core_lib` build scripts and static archive.
|
||||
3. Document behavior in [`nostr_core_lib/README.md`](../README.md).
|
||||
|
||||
## Phase 5: Consumer Integration in Didactyl
|
||||
|
||||
1. In didactyl initialization path near [`src/nostr_handler.c`](../../src/nostr_handler.c:1519), register `nostr_set_log_callback`.
|
||||
2. Adapter callback maps library levels to didactyl levels from [`src/debug.h`](../../src/debug.h:7).
|
||||
3. Prefix messages with source namespace such as `[nostr:websocket]` and `[nostr:nip013]`.
|
||||
|
||||
## Backward Compatibility Strategy
|
||||
|
||||
- Keep existing compile guards but change behavior from file output to callback emission.
|
||||
- If callback not set, behavior remains safe and silent.
|
||||
- No breaking changes for consumers not using logging.
|
||||
|
||||
## Testing Plan
|
||||
|
||||
### Unit Tests in `nostr_core_lib`
|
||||
|
||||
1. Add tests for callback registration and null behavior.
|
||||
2. Add tests for level filtering.
|
||||
3. Add tests that message formatting truncates safely and remains null terminated.
|
||||
|
||||
### Integration Checks in Didactyl
|
||||
|
||||
1. Start didactyl with debug enabled and callback wired.
|
||||
2. Verify websocket SEND and RECV lines appear through didactyl logger format from [`src/debug.c`](../../src/debug.c:31).
|
||||
3. Verify no separate websocket-only banner line from old path near [`nostr_websocket_openssl.c`](../nostr_websocket/nostr_websocket_openssl.c:1010).
|
||||
4. Verify LLM request log lines and nostr logs coexist in one log destination.
|
||||
|
||||
## Rollout Steps
|
||||
|
||||
1. Implement callback infrastructure and migrate websocket logging first.
|
||||
2. Validate no direct file writes remain in websocket module.
|
||||
3. Migrate nip013 logging.
|
||||
4. Add documentation and examples.
|
||||
5. Update didactyl wiring.
|
||||
6. Remove obsolete references to `ENABLE_FILE_LOGGING` for websocket logging behavior if no longer needed.
|
||||
|
||||
## Risks and Mitigations
|
||||
|
||||
- Risk: excessive callback volume from websocket trace traffic.
|
||||
- Mitigation: implement minimum level filter in library and map websocket traffic to trace level.
|
||||
- Risk: callback reentrancy or thread concerns.
|
||||
- Mitigation: document callback must be fast and thread-safe, avoid heavy blocking in callback.
|
||||
- Risk: API drift across consumers.
|
||||
- Mitigation: keep callback signature minimal and stable.
|
||||
|
||||
## Definition of Done
|
||||
|
||||
- No direct `fopen("debug.log", ...)` remains in production logging paths in `nostr_core_lib`.
|
||||
- Consumer can set callback and receive websocket and nip013 logs.
|
||||
- Didactyl routes nostr_core_lib logs through its logger and single configured destination.
|
||||
- Documentation updated with migration and usage examples.

# NIP-42 Authentication Support for core_relay_pool.c
|
||||
|
||||
## Problem Statement
|
||||
|
||||
The relay pool ([`core_relay_pool.c`](nostr_core/core_relay_pool.c)) does not handle NIP-42 authentication. When a relay sends an `AUTH` challenge message, the pool silently ignores it, causing:
|
||||
|
||||
- Subscriptions to fail on auth-required relays (events never delivered)
|
||||
- Publishes to be rejected with `auth-required:` errors
|
||||
- No visibility into authentication state per relay
|
||||
|
||||
The synchronous relay functions in [`core_relays.c`](nostr_core/core_relays.c) already have full NIP-42 support (lines 58-63, 211-239, 595-624). The NIP-42 primitives in [`nip042.c`](nostr_core/nip042.c) / [`nip042.h`](nostr_core/nip042.h) are production-ready. This plan wires them into the pool.
|
||||
|
||||

||||

||||

Q -->|No| S[Ignore or log]
|
||||
```
|
||||
|
||||
## Detailed Changes
|
||||
|
||||
### 1. Add NIP-42 include to core_relay_pool.c
|
||||
|
||||
Add `#include "nip042.h"` alongside the existing includes at the top of [`core_relay_pool.c`](nostr_core/core_relay_pool.c:27).
|
||||
|
||||
### 2. Add auth fields to `relay_connection_t` struct
|
||||
|
||||
Modeled after [`core_relays.c:58-63`](nostr_core/core_relays.c:58), add to the [`relay_connection_t`](nostr_core/core_relay_pool.c:76) struct:
|
||||
|
||||
```c
|
||||
// NIP-42 Authentication fields
|
||||
nostr_auth_state_t auth_state;
|
||||
char auth_challenge[NOSTR_NIP42_MAX_CHALLENGE_LENGTH];
|
||||
time_t auth_challenge_time;
|
||||
int nip42_enabled;
|
||||
```
|
||||
|
||||
These go after the existing `last_connection_error_time` field (around line 106).
|
||||
|
||||
### 3. Add private key and NIP-42 config to `nostr_relay_pool` struct
|
||||
|
||||
Add to the [`nostr_relay_pool`](nostr_core/core_relay_pool.c:146) struct:
|
||||
|
||||
```c
|
||||
// NIP-42 Authentication configuration
|
||||
int nip42_enabled;
|
||||
unsigned char private_key[32];
|
||||
int has_private_key;
|
||||
```
|
||||
|
||||
### 4. Add public API: `nostr_relay_pool_set_auth()`
|
||||
|
||||
Add to [`nostr_core.h`](nostr_core/nostr_core.h) after the existing pool management functions (around line 252):
|
||||
|
||||
```c
|
||||
// NIP-42 Authentication configuration for relay pool
|
||||
int nostr_relay_pool_set_auth(nostr_relay_pool_t* pool,
|
||||
const unsigned char* private_key,
|
||||
int enable);
|
||||
```
|
||||
|
||||
Implement in [`core_relay_pool.c`](nostr_core/core_relay_pool.c):
|
||||
- Copies the 32-byte private key into the pool struct
|
||||
- Sets `nip42_enabled` flag
|
||||
- Propagates `nip42_enabled` to all existing relay connections
|
||||
|
||||
### 5. Handle AUTH in `process_relay_message()`
|
||||
|
||||
Add an `AUTH` handler in [`process_relay_message()`](nostr_core/core_relay_pool.c:912) between the existing `OK` and `PONG` handlers (around line 1097). The logic mirrors [`core_relays.c:211-239`](nostr_core/core_relays.c:211):
|
||||
|
||||
```c
|
||||
} else if (strcmp(msg_type, "AUTH") == 0) {
|
||||
// Handle AUTH challenge: ["AUTH", <challenge-string>]
|
||||
if (pool->nip42_enabled && pool->has_private_key &&
|
||||
cJSON_IsArray(parsed) && cJSON_GetArraySize(parsed) >= 2) {
|
||||
cJSON* challenge_json = cJSON_GetArrayItem(parsed, 1);
|
||||
if (cJSON_IsString(challenge_json)) {
|
||||
const char* challenge = cJSON_GetStringValue(challenge_json);
|
||||
|
||||
// Store challenge
|
||||
strncpy(relay->auth_challenge, challenge,
|
||||
sizeof(relay->auth_challenge) - 1);
|
||||
relay->auth_challenge[sizeof(relay->auth_challenge) - 1] = '\0';
|
||||
relay->auth_challenge_time = time(NULL);
|
||||
relay->auth_state = NOSTR_AUTH_STATE_CHALLENGE_RECEIVED;
|
||||
|
||||
// Create and send auth event
|
||||
cJSON* auth_event = nostr_nip42_create_auth_event(
|
||||
challenge, relay->url, pool->private_key, 0);
|
||||
if (auth_event) {
|
||||
char* auth_message = nostr_nip42_create_auth_message(auth_event);
|
||||
if (auth_message) {
|
||||
if (nostr_ws_send_text(relay->ws_client, auth_message) >= 0) {
|
||||
relay->auth_state = NOSTR_AUTH_STATE_AUTHENTICATING;
|
||||
}
|
||||
free(auth_message);
|
||||
}
|
||||
cJSON_Delete(auth_event);
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 6. Handle AUTH in `nostr_relay_pool_query_sync()` inline loop
|
||||
|
||||
The [`nostr_relay_pool_query_sync()`](nostr_core/core_relay_pool.c:1107) function has its own inline message parsing loop (lines 1178-1227) that bypasses `process_relay_message()`. Add AUTH handling there too, similar to the pattern above.
|
||||
|
||||
### 7. Handle NOTICE messages
|
||||
|
||||
Add a `NOTICE` handler in [`process_relay_message()`](nostr_core/core_relay_pool.c:912):
|
||||
|
||||
```c
|
||||
} else if (strcmp(msg_type, "NOTICE") == 0) {
|
||||
// Handle NOTICE: ["NOTICE", <message>]
|
||||
if (cJSON_IsArray(parsed) && cJSON_GetArraySize(parsed) >= 2) {
|
||||
cJSON* notice_msg = cJSON_GetArrayItem(parsed, 1);
|
||||
if (cJSON_IsString(notice_msg)) {
|
||||
const char* notice = cJSON_GetStringValue(notice_msg);
|
||||
// Detect auth-required notices
|
||||
if (strstr(notice, "auth-required") != NULL) {
|
||||
relay->auth_state = NOSTR_AUTH_STATE_NONE; // Reset for re-auth
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 8. Handle OK auth-required rejections
|
||||
|
||||
Enhance the existing [`OK` handler](nostr_core/core_relay_pool.c:1048) to detect `auth-required:` prefix in error messages. When detected:
|
||||
- If the pool has a private key and the relay hasn't been authenticated yet, trigger the auth flow
|
||||
- Surface the rejection through the publish callback with the auth-required message
|
||||
|
||||
### 9. Initialize auth fields in `nostr_relay_pool_add_relay()`
|
||||
|
||||
In [`nostr_relay_pool_add_relay()`](nostr_core/core_relay_pool.c:605), initialize the new auth fields:
|
||||
|
||||
```c
|
||||
// Initialize NIP-42 authentication fields
|
||||
relay->auth_state = NOSTR_AUTH_STATE_NONE;
|
||||
memset(relay->auth_challenge, 0, sizeof(relay->auth_challenge));
|
||||
relay->auth_challenge_time = 0;
|
||||
relay->nip42_enabled = pool->nip42_enabled;
|
||||
```
|
||||
|
||||
### 10. Secure cleanup in `nostr_relay_pool_destroy()`
|
||||
|
||||
In [`nostr_relay_pool_destroy()`](nostr_core/core_relay_pool.c:684), zero the private key before freeing:
|
||||
|
||||
```c
|
||||
// Securely zero private key
|
||||
if (pool->has_private_key) {
|
||||
memset(pool->private_key, 0, sizeof(pool->private_key));
|
||||
pool->has_private_key = 0;
|
||||
}
|
||||
```
|
||||
|
||||
### 11. Test file
|
||||
|
||||
Create `tests/nip42_pool_test.c` that:
|
||||
- Creates a pool with auth configured
|
||||
- Verifies `nostr_relay_pool_set_auth()` stores the key
|
||||
- Simulates AUTH challenge parsing logic (unit-level, no live relay needed)
|
||||
- Verifies auth event creation with the pool's private key
|
||||
|
||||
### 12. Documentation updates
|
||||
|
||||
- Update [`POOL_API.md`](POOL_API.md) with `nostr_relay_pool_set_auth()` documentation
|
||||
- Update [`README.md`](README.md) with a relay pool NIP-42 usage example
|
||||

| [`nostr_core/nostr_core.h`](nostr_core/nostr_core.h) | Modified | Add `nostr_relay_pool_set_auth()` declaration |
|

|
||||
|
||||
## Key Design Decisions
|
||||
|
||||
1. **Private key stored in pool, not per-relay**: A single identity authenticates to all relays in the pool. This matches the common use case and mirrors how `core_relays.c` accepts a single `private_key` parameter.
|
||||
|
||||
2. **Auth state tracked per-relay**: Each relay connection tracks its own `nostr_auth_state_t` since different relays may challenge at different times.
|
||||
|
||||
3. **Automatic re-auth on reconnect**: When a relay reconnects (via the existing reconnection logic), the auth state resets to `NOSTR_AUTH_STATE_NONE`, allowing the relay to re-challenge.
|
||||
|
||||
4. **No blocking on auth**: The AUTH response is sent asynchronously. If a relay requires auth before accepting subscriptions, the relay will re-send events after authentication succeeds. The pool does not block waiting for auth confirmation.
|
||||
|
||||
5. **Reuse existing NIP-42 primitives**: All crypto and message formatting uses [`nostr_nip42_create_auth_event()`](nostr_core/nip042.c:26) and [`nostr_nip42_create_auth_message()`](nostr_core/nip042.c:84) — no new crypto code needed.

# NIP-46 Remote Signing — Implementation Plan
|
||||
|
||||
## Overview
|
||||
|
||||
NIP-46 defines a protocol for **Nostr Remote Signing**, enabling 2-way communication between a client application and a remote signer (bunker) over Nostr relays. The remote signer holds the user's private keys and performs cryptographic operations on behalf of the client, reducing the attack surface by keeping keys off the client device.
|
||||
|
||||
This plan covers implementing **both sides** of the protocol:
|
||||
- **Client-side**: sends requests to a remote signer and processes responses
|
||||
- **Remote-signer-side**: receives requests and produces responses (for building bunker applications)
|
||||
|
||||
## Architecture
|
||||
|
||||
### Protocol Flow

|
||||
|
||||
## Implementation Details
|
||||
|
||||
### URL Parsing Strategy
|
||||
|
||||
The `bunker://` and `nostrconnect://` URLs use standard URI format with query parameters. Implementation will:
|
||||
1. Validate the scheme prefix
|
||||
2. Extract the pubkey from the authority section
|
||||
3. Parse query parameters using simple string splitting — no external URL parsing library needed
|
||||
4. URL-decode relay values since they contain `://` characters
|
||||
|
||||
### NIP-44 Encryption Integration
|
||||
|
||||
All kind:24133 event content is NIP-44 encrypted. The implementation will use the existing `nostr_nip44_encrypt()` and `nostr_nip44_decrypt()` functions from `nip044.h`. The flow:
|
||||
1. Build JSON-RPC payload as a string
|
||||
2. Encrypt with `nostr_nip44_encrypt(client_privkey, remote_signer_pubkey, payload, ...)`
|
||||
3. Set as event content
|
||||
4. On receive: `nostr_nip44_decrypt(my_privkey, sender_pubkey, content, ...)`
|
||||
5. Parse decrypted JSON-RPC payload
|
||||
|
||||
### Relay Communication
|
||||
|
||||
For the initial implementation, the NIP-46 module will provide **event construction and parsing only** — it will not manage relay connections directly. Users will use the existing relay pool API to:
|
||||
1. Subscribe to kind:24133 events p-tagged to their pubkey
|
||||
2. Publish kind:24133 request/response events
|
||||
|
||||
This keeps the module focused and composable, matching the pattern used by NIP-59 and NIP-17.
|
||||
|
||||
A higher-level convenience layer could be added later that wraps the relay pool for a fully managed NIP-46 session.
|
||||
|
||||
### Auth Challenge Handling
|
||||
|
||||
When a response has `result: "auth_url"`, the error field contains a URL. The client-side API will return a specific error code `NOSTR_ERROR_NIP46_AUTH_CHALLENGE` and provide the URL in the response struct's error field, allowing the application to handle it appropriately.
|
||||
|
||||
## Test Plan
|
||||
|
||||
The test suite will cover:
|
||||
|
||||
1. **URL Parsing Tests**
|
||||
- Parse valid bunker:// URLs with single and multiple relays
|
||||
- Parse valid nostrconnect:// URLs with all optional fields
|
||||
- Reject malformed URLs
|
||||
- Handle URL-encoded relay values
|
||||
|
||||
2. **URL Generation Tests**
|
||||
- Generate bunker:// URLs and verify round-trip parsing
|
||||
- Generate nostrconnect:// URLs and verify round-trip parsing
|
||||
|
||||
3. **JSON-RPC Message Tests**
|
||||
- Create and parse each method type request
|
||||
- Create and parse success responses
|
||||
- Create and parse error responses
|
||||
- Verify request ID matching
|
||||
|
||||
4. **Event Construction Tests**
|
||||
- Create kind:24133 request events with proper encryption
|
||||
- Create kind:24133 response events with proper encryption
|
||||
- Decrypt events and verify content matches
|
||||
|
||||
5. **Method Enum Conversion Tests**
|
||||
- Round-trip all method enum values through string conversion
|
||||
|
||||
6. **Signer Request Handling Tests**
|
||||
- Handle connect request and produce ack response
|
||||
- Handle sign_event request and produce signed event response
|
||||
- Handle ping request and produce pong response
|
||||
- Handle get_public_key and return correct pubkey
|
||||
- Handle NIP-04/NIP-44 encrypt/decrypt requests
|
||||
|
||||
7. **End-to-End Flow Tests**
|
||||
- Client creates connect request → Signer handles → Client processes response
|
||||
- Client creates sign_event request → Signer signs → Client gets signed event
|
||||
- Full bunker:// connection flow
|
||||
- Secret validation on connect
|
||||
|
||||

# NIP-60 Cashu Wallet & NIP-61 Nutzaps — Implementation Plan
|
||||
|
||||
## Overview
|
||||
|
||||
**NIP-60** defines a protocol for storing Cashu wallet state on Nostr relays, enabling cross-application wallet portability. The wallet stores unspent proofs as encrypted events, tracks spending history, and manages mint relationships.
|
||||
|
||||
**NIP-61** defines "Nutzaps" — P2PK-locked Cashu tokens sent as zaps between Nostr users, where the payment itself serves as the receipt.
|
||||
|
||||
This implementation covers:
|
||||
- **NIP-60**: Wallet event creation/parsing (kind:17375), token events (kind:7375), spending history (kind:7376), quote events (kind:7374)
|
||||
- **NIP-61**: Nutzap info events (kind:10019), nutzap events (kind:9321), nutzap redemption
|
||||
- **Cashu Mint HTTP Client**: Mint info, token swap, melt, and mint operations via curl

|

|
||||
## Build System Changes
|
||||
|
||||
### build.sh Updates
|
||||
|
||||
1. Add `060` and `061` to the NIP detection patterns
|
||||
2. Add `cashu_mint.c` as a source when NIP-60 or NIP-61 is detected
|
||||
3. Add NIP descriptions: `NIP-060(Cashu-Wallet)`, `NIP-061(Nutzaps)`
|
||||
4. Update the `--nips=all` list to include `060` and `061`
|
||||
5. Update the help text with new NIP descriptions
|
||||
|
||||
### nostr_core.h Updates
|
||||
|
||||
Add includes:
|
||||
```c
|
||||
#include "nip060.h" // Cashu Wallet
|
||||
#include "nip061.h" // Nutzaps
|
||||
#include "cashu_mint.h" // Cashu Mint HTTP Client
|
||||
```
|
||||
|
||||
Add NIP-60/61 functions to the quick reference comment block.
|
||||
|
||||
## Implementation Order
|
||||
|
||||
The implementation should proceed in this order due to dependencies:
|
||||
|
||||
1. **Error codes** in `nostr_common.h` — no dependencies
|
||||
2. **Cashu proof types** — shared between NIP-60 and NIP-61
|
||||
3. **`cashu_mint.h/c`** — Cashu mint HTTP client (depends on curl, cJSON)
|
||||
4. **`nip060.h/c`** — NIP-60 wallet events (depends on NIP-44, NIP-01, cashu types)
|
||||
5. **`nip061.h/c`** — NIP-61 nutzaps (depends on NIP-60 types, cashu types)
|
||||
6. **Build system** — update `build.sh` and `nostr_core.h`
|
||||
7. **Tests** — `nip60_test.c`, `nip61_test.c`, `cashu_mint_test.c`
|
||||
8. **Example** — `cashu_wallet.c`
|
||||
|
||||
## Key Design Decisions
|
||||
|
||||
### 1. Self-encryption for NIP-44
|
||||
NIP-60 encrypts content to the user's own key (sender = recipient). The NIP-44 encrypt/decrypt functions take sender_private_key and recipient_public_key. For self-encryption, we derive the user's public key from their private key and use that as the recipient.
|
||||
|
||||
### 2. Cashu Crypto (Blinding)
|
||||
The Cashu protocol requires elliptic curve blinding operations (hash-to-curve, blind/unblind). These use secp256k1 which is already a dependency. The blinding math is:
|
||||
- `B_ = Y + r*G` where Y = hash_to_curve(secret), r = random blinding factor
|
||||
- `C_ = k*B_` (mint signs)
|
||||
- `C = C_ - r*K` where K = mint's public key (unblind)
|
||||
|
||||
### 3. P2PK Secrets
|
||||
For NIP-61 nutzaps, proof secrets use the P2PK format:
|
||||
```json
|
||||
["P2PK", {"nonce": "<random>", "data": "02<pubkey>"}]
|
||||
```
|
||||
The `02` prefix is required for nostr-cashu compatibility.
|
||||
|
||||
### 4. Curl Usage
|
||||
Following the same pattern as `nip005.c` — direct curl usage with write callbacks. No abstraction layer needed since curl is already a project dependency.
|
||||
|
||||
## Test Strategy
|
||||
|
||||
### NIP-60 Tests
|
||||
- Create and parse wallet events (round-trip encryption)
|
||||
- Create and parse token events with multiple proofs
|
||||
- Token deletion event creation
|
||||
- Rollover token creation with del references
|
||||
- History event creation and parsing
|
||||
- Quote event creation and parsing
|
||||
- Proof sum calculation
|
||||
- Filter creation helpers
|
||||
|
||||
### NIP-61 Tests
|
||||
- Create and parse nutzap info events
|
||||
- Create and parse nutzap events
|
||||
- Nutzap verification against kind:10019
|
||||
- Redemption history event creation
|
||||
- Filter creation helpers
|
||||
|
||||
### Cashu Mint Tests
|
||||
- Mint info parsing from JSON
|
||||
- Keyset parsing
|
||||
- Blinded message creation
|
||||
- Signature unblinding
|
||||
- P2PK secret generation
|
||||
- Proof state checking (mock or live mint)
|
||||
|
||||
