# Additional Requirements for WoT Implementation
|
||||
|
||||
This document identifies features and implementation details that are mentioned in the Brainstorm specification but lack detailed documentation. These items require further research, design decisions, or implementation details before the WoT system can be fully implemented in ORLY.
|
||||
|
||||
## 1. Algorithm Implementations
|
||||
|
||||
### 1.1 GrapeRank Algorithm
|
||||
|
||||
**Status:** Mentioned but not documented
|
||||
|
||||
**What's Specified:**
|
||||
- Computes 4 metrics: `influence`, `average`, `input`, `confidence`
|
||||
- Used to determine "verified" status (influence above threshold)
|
||||
- Applied to social graph structure (FOLLOWS, MUTES, REPORTS)
|
||||
|
||||
**What's Missing:**
|
||||

|
||||
- [ ] Integration of MUTES and REPORTS into the algorithm
|
||||

|
||||
|
||||
**Research Needed:**
|
||||

|
||||
1. Hops calculation (simpler than PageRank)
|
||||
2. Kind 3 (follows) processing
|
||||
3. NostrUser node creation and management
|
||||
4. Basic query filtering by hops
|
||||
5. Configuration system for owner pubkey and max hops
|
||||
|
||||
### Phase 2: Trust Metrics
|
||||
1. GrapeRank algorithm implementation (research and adapt)
|
||||
2. Personalized PageRank implementation
|
||||
3. Verified count calculations
|
||||
4. Kind 10000 (mutes) and kind 1984 (reports) processing
|
||||
5. WoT filter extension for REQ queries
|
||||
|
||||
### Phase 3: Multi-Tenant
|
||||
1. NostrUserWotMetricsCard node creation
|
||||
2. Customer management system
|
||||
3. Trust metrics API
|
||||
4. Per-customer metric computation
|
||||
5. NIP-85 Trusted Assertion generation
|
||||
|
||||
### Phase 4: Full Relay Mode
|
||||
1. Additional relationship types
|
||||
2. NostrEvent nodes
|
||||
3. Enhanced trust metrics with zaps/replies
|
||||
4. Ecosystem nodes (relays, mints)
|
||||
|
||||
## Summary
|
||||
|
||||
This document identifies **50+ specific implementation details** that are mentioned in the Brainstorm specification but lack sufficient detail for implementation. The most critical missing pieces are:
|
||||
|
||||
1. **Algorithm implementations** (GrapeRank, PageRank) - requires research or reverse engineering
|
||||
2. **Event processing logic** - requires detailed design for each event kind
|
||||
3. **Multi-tenant architecture** - requires customer management system design
|
||||
4. **NIP-56 and NIP-85 integration** - requires NIP specification review
|
||||
5. **Configuration system** - requires parameter identification and default values
|
||||
6. **Query API** - requires API design and authentication model
|
||||
7. **Performance optimization** - requires benchmarking and tuning
|
||||
8. **Testing strategy** - requires test data and validation methodology
|
||||
|
||||
These areas should be addressed systematically to build a complete WoT implementation for ORLY.

# Event-Driven Vertex Management Specification
|
||||
|
||||
This document specifies how Nostr events (specifically kind 0, 3, 1984, and 10000) are processed to maintain NostrUser vertices and social graph relationships (FOLLOWS, MUTES, REPORTS) in Neo4j, with full event traceability for diff-based updates.
|
||||
|
||||
## Overview
|
||||
|
||||
The event processing system must:
|
||||
1. **Capture** Nostr events that define social relationships
|
||||
2. **Generate/Update** NostrUser vertices from these events
|
||||
3. **Trace** relationships back to their source events
|
||||
4. **Diff** old vs new events to update the graph correctly
|
||||
5. **Handle** replaceable event semantics (newer replaces older)
|
||||
|
||||
## Core Principle: Event Traceability
|
||||
|
||||
Every relationship in the graph must be traceable to the event that created it. This enables:
|
||||
- **Diff-based updates**: When a replaceable event is updated, compare old vs new to determine which relationships to add/remove
|
||||
- **Event deletion**: When an event is deleted, remove associated relationships
|
||||
- **Auditing**: Track provenance of all social graph data
|
||||
- **Temporal queries**: Query the state of the graph at a specific point in time
|
||||
|
||||
## Data Model Extensions
|
||||
|
||||
### Relationship Properties for Traceability
|
||||
|
||||
All social graph relationships must include these properties:
|
||||
|
||||
```cypher
|
||||
// FOLLOWS relationship properties
|
||||
(:NostrUser)-[:FOLLOWS {
|
||||
created_by_event: "event_id_hex", // Event ID that created this relationship
|
||||
created_at: timestamp, // Event created_at timestamp
|
||||
relay_received_at: timestamp // When relay received the event
|
||||
}]->(:NostrUser)
|
||||
|
||||
// MUTES relationship properties
|
||||
(:NostrUser)-[:MUTES {
|
||||
created_by_event: "event_id_hex",
|
||||
created_at: timestamp,
|
||||
relay_received_at: timestamp
|
||||
}]->(:NostrUser)
|
||||
|
||||
// REPORTS relationship properties
|
||||
(:NostrUser)-[:REPORTS {
|
||||
created_by_event: "event_id_hex",
|
||||
created_at: timestamp,
|
||||
relay_received_at: timestamp,
|
||||
report_type: "spam|impersonation|illegal|..." // NIP-56 report type
|
||||
}]->(:NostrUser)
|
||||
```
|
||||
|
||||
### Event Tracking Node
|
||||
|
||||
Create a node to track which events have been processed and what relationships they created:
|
||||
|
||||
```cypher
|
||||
(:ProcessedSocialEvent {
|
||||
event_id: "hex_id", // Event ID
|
||||
event_kind: 3|1984|10000, // Event kind
|
||||
pubkey: "author_pubkey", // Event author
|
||||
created_at: timestamp, // Event timestamp
|
||||
processed_at: timestamp, // When we processed it
|
||||
relationship_count: integer, // How many relationships created
|
||||
superseded_by: "newer_event_id"|null // If replaced by newer event
|
||||
})
|
||||
```
|
||||
|
||||
## Event Processing Workflows
|
||||
|
||||
### Kind 3 (Contact List / Follows)
|
||||
|
||||
**Event Structure:**
|
||||
```json
|
||||
{
|
||||
"kind": 3,
|
||||
"pubkey": "user_pubkey",
|
||||
"created_at": 1234567890,
|
||||
"tags": [
|
||||
["p", "followed_pubkey_1", "relay_hint", "petname"],
|
||||
["p", "followed_pubkey_2", "relay_hint", "petname"],
|
||||
...
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**Processing Steps:**
|
||||
|
||||
1. **Check if replaceable event already exists**
|
||||
```cypher
|
||||
MATCH (existing:ProcessedSocialEvent {
|
||||
event_kind: 3,
|
||||
pubkey: $pubkey
|
||||
})
|
||||
WHERE existing.superseded_by IS NULL
|
||||
RETURN existing
|
||||
```
|
||||
|
||||
2. **If existing event found and new event is older**: Reject the event
|
||||
```
|
||||
if existing.created_at >= new_event.created_at:
|
||||
return EventRejected("Older event")
|
||||
```
|
||||
|
||||
3. **Extract p-tags from new event**
|
||||
```
|
||||
new_follows = set(tag[1] for tag in tags if tag[0] == 'p')
|
||||
```
|
||||
|
||||
4. **If replacing existing event, get old follows**
|
||||
```cypher
|
||||
MATCH (author:NostrUser {pubkey: $pubkey})-[r:FOLLOWS]->()
|
||||
WHERE r.created_by_event = $existing_event_id
|
||||
RETURN collect(endNode(r).pubkey) as old_follows
|
||||
```
|
||||
|
||||
5. **Compute diff**
|
||||
```python
|
||||
added_follows = new_follows - old_follows
|
||||
removed_follows = old_follows - new_follows
|
||||
```
|
||||
|
||||
6. **Transaction: Update graph atomically**
|
||||
```cypher
|
||||
// Begin transaction
|
||||
|
||||
// A. Mark old event as superseded
|
||||
MATCH (old:ProcessedSocialEvent {event_id: $old_event_id})
|
||||
SET old.superseded_by = $new_event_id
|
||||
|
||||
// B. Create new event tracking node
|
||||
CREATE (new:ProcessedSocialEvent {
|
||||
event_id: $new_event_id,
|
||||
event_kind: 3,
|
||||
pubkey: $pubkey,
|
||||
created_at: $created_at,
|
||||
processed_at: timestamp(),
|
||||
relationship_count: $new_follows_count,
|
||||
superseded_by: null
|
||||
})
|
||||
|
||||
// C. Remove old FOLLOWS relationships
|
||||
MATCH (author:NostrUser {pubkey: $pubkey})-[r:FOLLOWS]->(followed:NostrUser)
|
||||
WHERE r.created_by_event = $old_event_id
|
||||
AND followed.pubkey IN $removed_follows
|
||||
DELETE r
|
||||
|
||||
// D. Create new FOLLOWS relationships
|
||||
MERGE (author:NostrUser {pubkey: $pubkey})
|
||||
WITH author
|
||||
UNWIND $added_follows AS followed_pubkey
|
||||
MERGE (followed:NostrUser {pubkey: followed_pubkey})
|
||||
CREATE (author)-[:FOLLOWS {
|
||||
created_by_event: $new_event_id,
|
||||
created_at: $created_at,
|
||||
relay_received_at: $now
|
||||
}]->(followed)
|
||||
|
||||
// Commit transaction
|
||||
```
|
||||
|
||||
**Edge Cases:**
|
||||
- **Empty contact list**: User unfollows everyone (remove all FOLLOWS relationships)
|
||||
- **First contact list**: No existing event, create all relationships
|
||||
- **Duplicate p-tags**: Deduplicate before processing
|
||||
- **Invalid pubkeys**: Skip malformed pubkeys, log warning
|
||||
|
||||
### Kind 10000 (Mute List)
|
||||
|
||||
**Event Structure:**
|
||||
```json
|
||||
{
|
||||
"kind": 10000,
|
||||
"pubkey": "user_pubkey",
|
||||
"created_at": 1234567890,
|
||||
"tags": [
|
||||
["p", "muted_pubkey_1"],
|
||||
["p", "muted_pubkey_2"],
|
||||
...
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**Processing Steps:**
|
||||
|
||||
Same pattern as kind 3, but with MUTES relationships:
|
||||
|
||||
1. Check for existing kind 10000 from this pubkey
|
||||
2. If new event is older, reject
|
||||
3. Extract p-tags to get new mutes list
|
||||
4. Get old mutes list (if replacing)
|
||||
5. Compute diff: `added_mutes`, `removed_mutes`
|
||||
6. Transaction:
|
||||
- Mark old event as superseded
|
||||
- Create new ProcessedSocialEvent node
|
||||
- Delete removed MUTES relationships
|
||||
- Create added MUTES relationships
|
||||
|
||||
**Note on Privacy:**
|
||||
- Kind 10000 supports both public and encrypted tags
|
||||
- For encrypted tags, relationship tracking is limited (can't see who is muted)
|
||||
- Consider: Store relationship but set `muted_pubkey = "encrypted"` placeholder
|
||||
|
||||
### Kind 1984 (Reporting)
|
||||
|
||||
**Event Structure:**
|
||||
```json
|
||||
{
|
||||
"kind": 1984,
|
||||
"pubkey": "reporter_pubkey",
|
||||
"created_at": 1234567890,
|
||||
"tags": [
|
||||
["p", "reported_pubkey", "report_type"]
|
||||
],
|
||||
"content": "Optional reason"
|
||||
}
|
||||
```
|
||||
|
||||
**Processing Steps:**
|
||||
|
||||
Kind 1984 is **NOT replaceable**, so each report creates a separate relationship:
|
||||
|
||||
1. **Extract report data**
|
||||
```python
|
||||
for tag in tags:
|
||||
if tag[0] == 'p':
|
||||
reported_pubkey = tag[1]
|
||||
report_type = tag[2] if len(tag) > 2 else "other"
|
||||
```
|
||||
|
||||
2. **Create REPORTS relationship**
|
||||
```cypher
|
||||
// Transaction
|
||||
|
||||
// Create event tracking node
|
||||
CREATE (evt:ProcessedSocialEvent {
|
||||
event_id: $event_id,
|
||||
event_kind: 1984,
|
||||
pubkey: $reporter_pubkey,
|
||||
created_at: $created_at,
|
||||
processed_at: timestamp(),
|
||||
relationship_count: 1,
|
||||
superseded_by: null
|
||||
})
|
||||
|
||||
// Create or get reporter and reported users
|
||||
MERGE (reporter:NostrUser {pubkey: $reporter_pubkey})
|
||||
MERGE (reported:NostrUser {pubkey: $reported_pubkey})
|
||||
|
||||
// Create REPORTS relationship
|
||||
CREATE (reporter)-[:REPORTS {
|
||||
created_by_event: $event_id,
|
||||
created_at: $created_at,
|
||||
relay_received_at: timestamp(),
|
||||
report_type: $report_type
|
||||
}]->(reported)
|
||||
```
|
||||
|
||||
**Multiple Reports:**
|
||||
- Same user can report same target multiple times (different events)
|
||||
- Each creates a separate REPORTS relationship
|
||||
- Query aggregation needed to count total reports
|
||||
|
||||
**Report Types (NIP-56):**
|
||||
- `nudity` - Depictions of nudity, porn, etc
|
||||
- `profanity` - Profanity, hateful speech, etc
|
||||
- `illegal` - Illegal content
|
||||
- `spam` - Spam
|
||||
- `impersonation` - Someone pretending to be someone else
|
||||
- `malware` - Links to malware
|
||||
- `other` - Other reasons
|
||||
|
||||
### Kind 0 (Profile Metadata)
|
||||
|
||||
**Event Structure:**
|
||||
```json
|
||||
{
|
||||
"kind": 0,
|
||||
"pubkey": "user_pubkey",
|
||||
"created_at": 1234567890,
|
||||
"content": "{\"name\":\"Alice\",\"about\":\"...\",\"picture\":\"...\"}"
|
||||
}
|
||||
```
|
||||
|
||||
**Processing Steps:**
|
||||
|
||||
1. **Parse profile JSON**
|
||||
```python
|
||||
profile = json.loads(event.content)
|
||||
```
|
||||
|
||||
2. **Update NostrUser properties**
|
||||
```cypher
|
||||
MERGE (user:NostrUser {pubkey: $pubkey})
|
||||
ON CREATE SET
|
||||
user.created_at = $now,
|
||||
user.first_seen_event = $event_id
|
||||
ON MATCH SET
|
||||
user.last_profile_update = $created_at
|
||||
SET
|
||||
user.name = $profile.name,
|
||||
user.about = $profile.about,
|
||||
user.picture = $profile.picture,
|
||||
user.nip05 = $profile.nip05,
|
||||
user.lud16 = $profile.lud16,
|
||||
user.display_name = $profile.display_name
|
||||
```
|
||||
|
||||
**Note:** Kind 0 is replaceable, but we typically keep only latest profile data (not diffing relationships).
|
||||
|
||||
## Implementation Architecture
|
||||
|
||||
### Event Processor Interface
|
||||
|
||||
```go
|
||||
package neo4j
|
||||
|
||||
import (
|
||||
"context"
|
||||
"git.mleku.dev/mleku/nostr/encoders/event"
|
||||
)
|
||||
|
||||
// SocialEventProcessor handles kind 0, 3, 1984, 10000 events
|
||||
type SocialEventProcessor struct {
|
||||
db *N
|
||||
}
|
||||
|
||||
// ProcessSocialEvent routes events to appropriate handlers
|
||||
func (p *SocialEventProcessor) ProcessSocialEvent(ctx context.Context, ev *event.E) error {
|
||||
switch ev.Kind {
|
||||
case 0:
|
||||
return p.processProfileMetadata(ctx, ev)
|
||||
case 3:
|
||||
return p.processContactList(ctx, ev)
|
||||

||||
return p.processReport(ctx, ev)
|
||||
case 10000:
|
||||
return p.processMuteList(ctx, ev)
|
||||
default:
|
||||
return fmt.Errorf("unsupported social event kind: %d", ev.Kind)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Contact List Processor (Kind 3)

||||
|
||||
```go
|
||||

|
||||

|
||||
eventID := hex.Enc(ev.ID[:])
|
||||
|
||||
// 1. Check for existing contact list
|
||||
existingEvent, err := p.getLatestSocialEvent(ctx, authorPubkey, 3)
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
|
||||
// 2. Reject if older
|
||||
if existingEvent != nil && existingEvent.CreatedAt >= ev.CreatedAt {
|
||||
return fmt.Errorf("older contact list event rejected")
|
||||
}
|
||||
|
||||
// 3. Extract p-tags
|
||||
newFollows := extractPTags(ev)
|
||||
|
||||
// 4. Get old follows (if replacing)
|
||||
var oldFollows []string
|
||||
if existingEvent != nil {
|
||||
oldFollows, err = p.getFollowsForEvent(ctx, existingEvent.EventID)
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
}
|
||||
|
||||
// 5. Compute diff
|
||||
added, removed := diffStringSlices(oldFollows, newFollows)
|
||||
|
||||
// 6. Update graph in transaction

}
|

|
||||
func (p *SocialEventProcessor) updateContactListGraph(ctx context.Context, params UpdateContactListParams) error {
|
||||
// Build complex Cypher transaction
|
||||
cypher := `

### Helper Functions
|
||||
|
||||
```go
|
||||
// extractPTags extracts unique pubkeys from p-tags
|
||||
func extractPTags(ev *event.E) []string {
|
||||
seen := make(map[string]bool)
|
||||
var pubkeys []string
|
||||
|
||||
for _, tag := range *ev.Tags {
|
||||
if len(tag.T) >= 2 && string(tag.T[0]) == "p" {
|
||||
pubkey := string(tag.T[1])
|
||||
if !seen[pubkey] {
|
||||
seen[pubkey] = true
|
||||
pubkeys = append(pubkeys, pubkey)
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
return pubkeys
|
||||
}
|
||||
|
||||
// diffStringSlices computes added and removed elements
|
||||
func diffStringSlices(old, new []string) (added, removed []string) {
|
||||
oldSet := make(map[string]bool)
|
||||
for _, s := range old {
|
||||
oldSet[s] = true
|
||||
}
|
||||
|
||||
newSet := make(map[string]bool)
|
||||
for _, s := range new {
|
||||
newSet[s] = true
|
||||
if !oldSet[s] {
|
||||
added = append(added, s)
|
||||
}
|
||||
}
|
||||
|
||||
for _, s := range old {
|
||||
if !newSet[s] {
|
||||
removed = append(removed, s)
|
||||
}
|
||||
}
|
||||
|
||||
return
|
||||
}
|
||||
```
|
||||
|
||||
## Integration with SaveEvent
|
||||
|
||||
The social event processor should be called from the existing `SaveEvent` method:
|
||||
|
||||
```go
|
||||
// In pkg/neo4j/save-event.go
|
||||
|
||||
func (n *N) SaveEvent(c context.Context, ev *event.E) (exists bool, err error) {
|
||||
// ... existing event save logic ...
|
||||
|
||||
// After saving base event, process social graph updates
|
||||
if ev.Kind == 0 || ev.Kind == 3 || ev.Kind == 1984 || ev.Kind == 10000 {
|
||||
processor := &SocialEventProcessor{db: n}
|
||||
if err := processor.ProcessSocialEvent(c, ev); err != nil {
|
||||
n.Logger.Errorf("failed to process social event: %v", err)
|
||||
// Decide: fail the whole save or just log error?
|
||||
}
|
||||
}
|
||||
|
||||
return false, nil
|
||||
}
|
||||
```
|
||||
|
||||
## Schema Updates Required
|
||||
|
||||
Add ProcessedSocialEvent node to schema.go:
|
||||
|
||||
```go
|
||||
// In applySchema, add:
|
||||
constraints = append(constraints,
|
||||
// Unique constraint on ProcessedSocialEvent.event_id
|
||||
"CREATE CONSTRAINT processedSocialEvent_event_id IF NOT EXISTS FOR (e:ProcessedSocialEvent) REQUIRE e.event_id IS UNIQUE",
|
||||
)
|
||||
|
||||
indexes = append(indexes,
|
||||
// Index on ProcessedSocialEvent for quick lookup
|
||||
"CREATE INDEX processedSocialEvent_pubkey_kind IF NOT EXISTS FOR (e:ProcessedSocialEvent) ON (e.pubkey, e.event_kind)",
|
||||
"CREATE INDEX processedSocialEvent_superseded IF NOT EXISTS FOR (e:ProcessedSocialEvent) ON (e.superseded_by)",
|
||||
)
|
||||
```
|
||||
|
||||
## Query Patterns
|
||||
|
||||
### Get User's Current Follows
|
||||
|
||||
```cypher
|
||||
// Get all users followed by a user (from most recent event)
|
||||
MATCH (user:NostrUser {pubkey: $pubkey})-[f:FOLLOWS]->(followed:NostrUser)
|
||||
WHERE NOT EXISTS {
|
||||
MATCH (old:ProcessedSocialEvent {event_id: f.created_by_event})
|
||||
WHERE old.superseded_by IS NOT NULL
|
||||
}
|
||||
RETURN followed.pubkey, f.created_at
|
||||
ORDER BY f.created_at DESC
|
||||
```
|
||||
|
||||
### Get User's Current Mutes
|
||||
|
||||
```cypher
|
||||
MATCH (user:NostrUser {pubkey: $pubkey})-[m:MUTES]->(muted:NostrUser)
|
||||
WHERE NOT EXISTS {
|
||||
MATCH (old:ProcessedSocialEvent {event_id: m.created_by_event})
|
||||
WHERE old.superseded_by IS NOT NULL
|
||||
}
|
||||
RETURN muted.pubkey
|
||||
```
|
||||
|
||||
### Count Reports Against User
|
||||
|
||||
```cypher
|
||||
MATCH (reporter:NostrUser)-[r:REPORTS]->(reported:NostrUser {pubkey: $pubkey})
|
||||
RETURN r.report_type, count(*) as report_count
|
||||
ORDER BY report_count DESC
|
||||
```
|
||||
|
||||
### Get Social Graph History
|
||||
|
||||
```cypher
|
||||
// Get all contact list events for a user, in order
|
||||
MATCH (evt:ProcessedSocialEvent {pubkey: $pubkey, event_kind: 3})
|
||||
RETURN evt.event_id, evt.created_at, evt.relationship_count, evt.superseded_by
|
||||
ORDER BY evt.created_at DESC
|
||||
```
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
### Unit Tests
|
||||
|
||||
1. **Diff calculation tests**
|
||||
- Empty lists
|
||||
- No changes
|
||||
- All new follows
|
||||
- All removed follows
|
||||
- Mixed additions and removals
|
||||
|
||||
2. **Event ordering tests**
|
||||
- Newer event replaces older
|
||||
- Older event rejected
|
||||
- Same timestamp handling
|
||||
|
||||
3. **P-tag extraction tests**
|
||||
- Valid tags
|
||||
- Duplicate pubkeys
|
||||
- Malformed tags
|
||||
- Empty tag lists
|
||||
|
||||
### Integration Tests
|
||||
|
||||
1. **Contact list update flow**
|
||||
- Create initial contact list
|
||||
- Update with additions
|
||||
- Update with removals
|
||||
- Verify graph state at each step
|
||||
|
||||
2. **Multiple users**
|
||||
- Alice follows Bob
|
||||
- Bob follows Charlie
|
||||
- Alice unfollows Bob
|
||||
- Verify relationships
|
||||
|
||||
3. **Concurrent updates**
|
||||
- Multiple events for same user
|
||||
- Verify transaction isolation
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Batch Processing
|
||||
|
||||
For initial graph population from existing events:
|
||||
|
||||
```go
|
||||
func (p *SocialEventProcessor) BatchProcessContactLists(ctx context.Context, events []*event.E) error {
|
||||
// Group by author
|
||||
byAuthor := make(map[string][]*event.E)
|
||||
for _, ev := range events {
|
||||
pubkey := hex.Enc(ev.Pubkey[:])
|
||||
byAuthor[pubkey] = append(byAuthor[pubkey], ev)
|
||||
}
|
||||
|
||||
// Process each author's events in order
|
||||
for pubkey, authorEvents := range byAuthor {
|
||||
// Sort by created_at
|
||||
sort.Slice(authorEvents, func(i, j int) bool {
|
||||
return authorEvents[i].CreatedAt < authorEvents[j].CreatedAt
|
||||
})
|
||||
|
||||
// Process in order (older to newer)
|
||||
for _, ev := range authorEvents {
|
||||
if err := p.processContactList(ctx, ev); err != nil {
|
||||
return fmt.Errorf("batch process failed for %s: %w", pubkey, err)
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
return nil
|
||||
}
|
||||
```
|
||||
|
||||
### Index Strategy
|
||||
|
||||
- Index on `(pubkey, event_kind)` for fast lookup of latest event
|
||||
- Index on `superseded_by` to filter active relationships
|
||||
- Index on relationship `created_by_event` for diff operations
|
||||
|
||||
### Memory Management
|
||||
|
||||
- Process events in batches to avoid loading all into memory
|
||||
- Use streaming queries for large result sets
|
||||
- Set reasonable limits on relationship counts per user
|
||||
|
||||
## Error Handling
|
||||
|
||||
### Validation Errors
|
||||
|
||||
- Malformed pubkeys → skip, log warning
|
||||
- Invalid JSON in kind 0 → skip profile update
|
||||
- Missing required tags → skip event
|
||||
|
||||
### Graph Errors
|
||||
|
||||
- Neo4j connection failure → retry with backoff
|
||||
- Transaction timeout → reduce batch size
|
||||
- Constraint violation → likely race condition, retry
|
||||
|
||||
### Recovery Strategies
|
||||
|
||||
- Failed event processing → mark event for retry
|
||||
- Partial transaction → rollback and retry
|
||||
- Data inconsistency → repair tool to rebuild from events
|
||||
|
||||
## Monitoring and Observability
|
||||
|
||||
### Metrics to Track
|
||||
|
||||
- Events processed per second (by kind)
|
||||
- Average relationships per contact list
|
||||
- Diff operation sizes (added/removed counts)
|
||||
- Transaction durations
|
||||
- Error rates by error type
|
||||
|
||||
### Logging
|
||||
|
||||
```go
|
||||
n.Logger.Infof("processed contact list: author=%s, event=%s, added=%d, removed=%d",
|
||||
authorPubkey, eventID, len(added), len(removed))
|
||||
```
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
1. **Temporal snapshots**: Store full graph state at regular intervals
|
||||
2. **Event sourcing**: Replay event log to reconstruct graph
|
||||
3. **Analytics**: Track follow/unfollow patterns over time
|
||||
4. **Recommendations**: Suggest users to follow based on graph
|
||||
5. **Privacy**: Encrypted relationship support (NIP-17, NIP-59)
|
||||
|
||||
## Summary
|
||||
|
||||
This specification provides a complete event-driven vertex management system that:
|
||||
- ✅ Captures social graph events (kinds 0, 3, 1984, 10000)
|
||||
- ✅ Maintains NostrUser vertices with traceability
|
||||
- ✅ Diffs replaceable events to update relationships correctly
|
||||
- ✅ Supports relationship queries with event provenance
|
||||
- ✅ Handles edge cases and error conditions
|
||||
- ✅ Provides clear implementation path with Go code examples
|
||||
|
||||
The system is ready to be implemented as the foundation for WoT trust metrics computation.

# Event-Driven Vertex Management Implementation Summary
|
||||
|
||||
## What Was Implemented
|
||||
|
||||
This document summarizes the event-driven vertex management system for maintaining NostrUser nodes and social graph relationships in the ORLY Neo4j backend.
|
||||
|
||||
## Architecture Overview
|
||||
|
||||
### Dual Node System
|
||||
|
||||
The implementation uses two separate node types:
|
||||
|
||||
1. **Event and Author nodes** (NIP-01 Support)
|
||||
- Created by `SaveEvent()` for ALL events
|
||||
- Used for standard Nostr REQ filter queries
|
||||
- Supports kinds, authors, tags, time ranges, etc.
|
||||
- **Always maintained** - this is the core relay functionality
|
||||
|
||||
2. **NostrUser nodes** (Social Graph / WoT)
|
||||
- Created by `SocialEventProcessor` for kinds 0, 3, 1984, 10000
|
||||
- Used for social graph queries and Web of Trust metrics
|
||||
- Connected by FOLLOWS, MUTES, REPORTS relationships
|
||||
- **Event traceable** - every relationship links back to the event that created it
|
||||
|
||||
This dual approach ensures **NIP-01 queries continue to work** while adding social graph capabilities.
|
||||

## Data Model
|
||||
|
||||
### Node Types
|
||||
|
||||
#### ProcessedSocialEvent (Tracking Node)
|
||||
```cypher
|
||||
(:ProcessedSocialEvent {
|
||||
event_id: string, // Hex event ID
|
||||
event_kind: int, // 0, 3, 1984, or 10000
|
||||
pubkey: string, // Author pubkey
|
||||
created_at: timestamp, // Event timestamp
|
||||
processed_at: timestamp, // When relay processed it
|
||||
relationship_count: int, // How many relationships created
|
||||
superseded_by: string|null // If replaced by newer event
|
||||
})
|
||||
```
|
||||
|
||||
#### NostrUser (Social Graph Vertex)
|
||||
```cypher
|
||||
(:NostrUser {
|
||||
pubkey: string, // Hex pubkey (unique)
|
||||
npub: string, // Bech32 npub
|
||||
name: string, // Profile name
|
||||
about: string, // Profile about
|
||||
picture: string, // Profile picture URL
|
||||
nip05: string, // NIP-05 identifier
|
||||
// ... other profile fields
|
||||
// ... trust metrics (future)
|
||||
})
|
||||
```
|
||||
|
||||
### Relationship Types (With Event Traceability)
|
||||
|
||||
#### FOLLOWS
|
||||
```cypher
|
||||
(:NostrUser)-[:FOLLOWS {
|
||||
created_by_event: string, // Event ID that created this
|
||||
created_at: timestamp, // Event timestamp
|
||||
relay_received_at: timestamp
|
||||
}]->(:NostrUser)
|
||||
```
|
||||
|
||||
#### MUTES
|
||||
```cypher
|
||||
(:NostrUser)-[:MUTES {
|
||||
created_by_event: string,
|
||||
created_at: timestamp,
|
||||
relay_received_at: timestamp
|
||||
}]->(:NostrUser)
|
||||
```
|
||||
|
||||
#### REPORTS
|
||||
```cypher
|
||||
(:NostrUser)-[:REPORTS {
|
||||
created_by_event: string,
|
||||
created_at: timestamp,
|
||||
relay_received_at: timestamp,
|
||||
report_type: string // NIP-56 type (spam, illegal, etc.)
|
||||
}]->(:NostrUser)
|
||||
```
|
||||
|
||||
## Event Processing Flow
|
||||
|
||||
### Kind 3 (Contact List) - Follow Relationships
|
||||
|
||||
```
|
||||
1. Receive kind 3 event
|
||||
2. Check if event already exists (base Event node)
|
||||
└─ If exists: return (already processed)
|
||||
3. Save base Event + Author nodes (NIP-01)
|
||||
4. Social processing:
|
||||
a. Check for existing kind 3 from this pubkey
|
||||
b. If new event is older: skip (don't replace newer with older)
|
||||
c. Extract p-tags from new event → new_follows[]
|
||||
d. Query old FOLLOWS relationships → old_follows[]
|
||||
e. Compute diff:
|
||||
- added_follows = new_follows - old_follows
|
||||
- removed_follows = old_follows - new_follows
|
||||
f. Transaction:
|
||||
- Mark old ProcessedSocialEvent as superseded
|
||||
- Create new ProcessedSocialEvent
|
||||
- DELETE removed FOLLOWS relationships
|
||||
- CREATE added FOLLOWS relationships
|
||||
g. Log: "processed contact list: added=X, removed=Y"
|
||||
```
|
||||
|
||||
**Example:**
|
||||
```
|
||||
Event 1: Alice follows [Bob, Charlie]
|
||||
→ Creates FOLLOWS to Bob and Charlie
|
||||
|
||||
Event 2: Alice follows [Bob, Dave] (newer)
|
||||
→ Diff: added=[Dave], removed=[Charlie]
|
||||
→ Marks Event 1 as superseded
|
||||
→ Deletes FOLLOWS to Charlie
|
||||
→ Creates FOLLOWS to Dave
|
||||
→ Result: Alice follows [Bob, Dave]
|
||||
```
|
||||
|
||||
### Kind 10000 (Mute List) - Mute Relationships
|
||||
|
||||
Same pattern as kind 3, but creates/updates MUTES relationships.
|
||||
|
||||
### Kind 1984 (Reporting) - Report Relationships
|
||||
|
||||
**Different:** Kind 1984 is NOT replaceable.
|
||||
|
||||
```
|
||||
1. Receive kind 1984 event
|
||||
2. Save base Event + Author nodes
|
||||
3. Social processing:
|
||||
a. Extract p-tag (reported user) and report type
|
||||
b. Create ProcessedSocialEvent node
|
||||
c. Create REPORTS relationship (new, not replacing old)
|
||||
```
|
||||
|
||||
**Multiple Reports:** Same user can report same target multiple times. Each creates a separate REPORTS relationship.
|
||||
|
||||
### Kind 0 (Profile Metadata) - User Properties
|
||||
|
||||
```
|
||||
1. Receive kind 0 event
|
||||
2. Save base Event + Author nodes
|
||||
3. Social processing:
|
||||
a. Parse JSON content
|
||||
b. MERGE NostrUser (create if not exists)
|
||||
c. SET profile properties (name, about, picture, etc.)
|
||||
```
|
||||
|
||||
**Note:** Kind 0 is replaceable, but we don't diff - just update all profile fields.
|
||||
|
||||
## Key Design Decisions
|
||||
|
||||
### 1. Event Traceability
|
||||
|
||||
**All relationships include `created_by_event` property.**
|
||||
|
||||
This enables:
|
||||
- Diff-based updates (know which relationships to remove when event is replaced)
|
||||
- Event deletion (remove associated relationships)
|
||||
- Auditing (track provenance of all data)
|
||||
- Temporal queries (state of graph at specific time)
|
||||
|
||||
### 2. Separate Event Tracking Node (ProcessedSocialEvent)
|
||||
|
||||
Instead of marking Event nodes as processed, we use a separate ProcessedSocialEvent node.
|
||||
|
||||
**Why?**
|
||||
- Event node represents the raw Nostr event (immutable)
|
||||
- ProcessedSocialEvent tracks our processing state (mutable)
|
||||
- Can have multiple processing states for same event (future: different algorithms)
|
||||
- Clean separation of concerns
|
||||
|
||||
### 3. Superseded Chain
|
||||
|
||||
When a replaceable event is updated:
|
||||
- Old ProcessedSocialEvent.superseded_by = new_event_id
|
||||
- New ProcessedSocialEvent.superseded_by = null
|
||||
|
||||
This creates a chain: Event1 → Event2 → Event3 (current)
|
||||
|
||||
**Benefits:**
|
||||
- Can query history of user's follows over time
|
||||
- Can reconstruct graph at any point in time
|
||||
- Can debug issues ("why was this relationship removed?")
|
||||
|
||||
### 4. Non-Blocking Social Processing
|
||||
|
||||
Social event processing errors are logged but don't fail the base event save.
|
||||
|
||||
**Rationale:**
|
||||
- NIP-01 queries are the core relay function
|
||||
- Social graph is supplementary (for WoT, filtering, etc.)
|
||||
- Relay should continue operating even if social processing fails
|
||||
- Can reprocess events later if social processing was fixed
|
||||
|
||||
### 5. Dual Node System (Event/Author vs. NostrUser)
|
||||
|
||||
**Why not merge Author and NostrUser?**
|
||||
- Event and Author are for NIP-01 queries (fast, simple)
|
||||
- NostrUser is for social graph (complex relationships)
|
||||
- Different query patterns and optimization strategies
|
||||
- Keeps social graph overhead separate from core relay performance
|
||||
- Future: May merge, but keep separate for now (pre-alpha)
|
||||
|
||||
## Query Examples
|
||||
|
||||
### Get Current Follows for User
|
||||
|
||||
```cypher
|
||||
MATCH (user:NostrUser {pubkey: $pubkey})-[f:FOLLOWS]->(followed:NostrUser)
|
||||
WHERE NOT EXISTS {
|
||||
MATCH (old:ProcessedSocialEvent {event_id: f.created_by_event})
|
||||
WHERE old.superseded_by IS NOT NULL
|
||||
}
|
||||
RETURN followed.pubkey, followed.name
|
||||
```
|
||||
|
||||
### Get Mutual Follows (Friends)
|
||||
|
||||
```cypher
|
||||
MATCH (user:NostrUser {pubkey: $pubkey})-[:FOLLOWS]->(friend:NostrUser)
|
||||
-[:FOLLOWS]->(user)
|
||||
RETURN friend.pubkey, friend.name
|
||||
```
|
||||
|
||||
### Count Reports by Type
|
||||
|
||||
```cypher
|
||||
MATCH (reported:NostrUser {pubkey: $pubkey})<-[r:REPORTS]-()
|
||||
RETURN r.report_type, count(*) as count
|
||||
ORDER BY count DESC
|
||||
```
|
||||
|
||||
### Follow Graph History
|
||||
|
||||
```cypher
|
||||
MATCH (evt:ProcessedSocialEvent {pubkey: $pubkey, event_kind: 3})
|
||||
RETURN evt.event_id, evt.created_at, evt.relationship_count, evt.superseded_by
|
||||
ORDER BY evt.created_at ASC
|
||||
```
|
||||
|
||||
## Testing Plan
|
||||
|
||||
### Unit Tests
|
||||
|
||||
1. **Diff computation**
|
||||
- Empty lists
|
||||
- All new, all removed
|
||||
- Mixed additions and removals
|
||||
- Duplicate handling
|
||||
|
||||
2. **Event ordering**
|
||||
- Newer replaces older
|
||||
- Older rejected
|
||||
- Same timestamp
|
||||
|
||||
3. **P-tag extraction**
|
||||
- Valid tags
|
||||
- Invalid pubkeys
|
||||
- Empty lists
|
||||
|
||||
### Integration Tests
|
||||
|
||||
1. **Contact list updates**
|
||||
- Initial list
|
||||
- Add follows
|
||||
- Remove follows
|
||||
- Replace entire list
|
||||
- Empty list (unfollow all)
|
||||
|
||||
2. **Multiple users**
|
||||
- Alice follows Bob
|
||||
- Bob follows Charlie
|
||||
- Verify independent updates
|
||||
|
||||
3. **Replaceable event semantics**
|
||||
- Older event arrives after newer
|
||||
- Verify rejection
|
||||
|
||||
4. **Report accumulation**
|
||||
- Multiple reports from same user
|
||||
- Multiple users reporting same target
|
||||
- Different report types
|
||||
|
||||
### Performance Tests
|
||||
|
||||
1. **Large contact lists**
|
||||
- 1000+ follows
|
||||
- Diff computation time
|
||||
- Transaction time
|
||||
|
||||
2. **High volume**
|
||||
- 1000 events/sec
|
||||
- Graph write throughput
|
||||
- Query performance
|
||||
|
||||
## Next Steps

||||
|
||||

|
||||
- [ ] Multi-tenant support
|
||||
|
||||
## Configuration
|
||||
|
||||
Currently **no configuration needed** - social event processing is automatic for kinds 0, 3, 1984, 10000.
|
||||
|
||||
Future configuration options:
|
||||
```bash
|
||||
# Enable/disable social graph processing
|
||||
ORLY_SOCIAL_GRAPH_ENABLED=true
|
||||
|
||||
# Which event kinds to process
|
||||
ORLY_SOCIAL_GRAPH_KINDS=0,3,1984,10000
|
||||
|
||||
# Batch size for initial sync
|
||||
ORLY_SOCIAL_GRAPH_BATCH_SIZE=1000
|
||||
|
||||
# Enable WoT metrics computation (future)
|
||||
ORLY_WOT_ENABLED=false
|
||||
```
|
||||
|
||||
## Monitoring
|
||||
|
||||
### Metrics to Track
|
||||
|
||||
- Events processed per second (by kind)
|
||||
- Average diff size (added/removed counts)
|
||||
- Transaction durations
|
||||
- Error rates by error type
|
||||
- Graph size (node/relationship counts)
|
||||
|
||||
### Logs to Monitor
|
||||
|
||||
```
|
||||
INFO: processed contact list: author=abc123, added=5, removed=2, total=50
|
||||
INFO: processed mute list: author=abc123, added=1, removed=0
|
||||
INFO: processed report: reporter=abc123, reported=def456, type=spam
|
||||
ERROR: failed to process social event kind 3: <error details>
|
||||
```
|
||||
|
||||
## Known Limitations
|
||||
|
||||
1. **No event deletion support yet**
|
||||
- Kind 5 (event deletion) not implemented
|
||||
- Relationships persist even if event deleted
|
||||
|
||||
2. **No encrypted tag support**
|
||||
- Kind 10000 can have encrypted tags (private mutes)
|
||||
- Currently only processes public tags
|
||||
|
||||
3. **No temporal queries yet**
|
||||
- Can't query "who did Alice follow on 2024-01-01?"
|
||||
- Superseded chain exists but query API not implemented
|
||||
|
||||
4. **No batch import tool**
|
||||
- Processing events one at a time
|
||||
- Need tool for initial sync from existing relay
|
||||
|
||||
5. **No trust metrics computation**
|
||||
- NostrUser nodes created but metrics not calculated
|
||||
- Requires Phase 3 implementation
|
||||
|
||||
## Performance Characteristics
|
||||
|
||||
### Expected Performance
|
||||
|
||||
- **Small contact lists** (< 100 follows): < 100ms per event
|
||||
- **Medium contact lists** (100-500 follows): 100-500ms per event
|
||||
- **Large contact lists** (500-1000 follows): 500-1000ms per event
|
||||
- **Very large contact lists** (> 1000 follows): May need optimization
|
||||
|
||||
### Bottlenecks
|
||||
|
||||
1. **Diff computation** - O(n) where n = max(old_size, new_size)
|
||||
2. **Graph writes** - Neo4j transaction overhead
|
||||
3. **Multiple network round trips** - Could batch queries
|
||||
|
||||
### Optimization Opportunities
|
||||
|
||||
1. Use APOC procedures for batch operations
|
||||
2. Cache frequently accessed user data
|
||||
3. Parallelize independent social event processing
|
||||
4. Use Neo4j Graph Data Science library for trust metrics
|
||||
|
||||

# Neo4j Social Event Processor
|
||||
|
||||
A graph-native implementation for managing Nostr social relationships in Neo4j, providing Web of Trust (WoT) capabilities for the ORLY relay.
|
||||
|
||||
## Overview
|
||||
|
||||
The Social Event Processor automatically processes Nostr events that define social relationships and stores them as a navigable graph in Neo4j. This enables powerful social graph queries, trust metrics computation, and relationship-aware content filtering.
|
||||
|
||||
When events are saved to the relay, the processor intercepts social event types and maintains a parallel graph of `NostrUser` nodes connected by relationship edges (`FOLLOWS`, `MUTES`, `REPORTS`). This graph is separate from the standard NIP-01 event storage, optimized specifically for social graph operations.
|
||||
|
||||
## Supported Event Kinds
|
||||
|
||||
### Kind 0 - Profile Metadata
|
||||
|
||||
Creates or updates `NostrUser` nodes with profile information extracted from the event content:
|
||||
- Display name
|
||||
- About/bio
|
||||
- Profile picture URL
|
||||
- NIP-05 identifier
|
||||
- Lightning address (lud16)
|
||||
|
||||
Profile updates are applied whenever a newer kind 0 event is received for a pubkey.
|
||||
|
||||
### Kind 3 - Contact Lists (Follows)
|
||||
|
||||
Manages `FOLLOWS` relationships between users using an efficient diff-based approach:
|
||||
- When a new contact list arrives, the processor compares it to the previous list
|
||||
- Only changed relationships are modified (added or removed)
|
||||
- Unchanged follows are preserved with updated event traceability
|
||||
- Older events (by timestamp) are automatically rejected
|
||||
|
||||
This approach minimizes graph operations for large follow lists where only a few changes occur.
|
||||
|
||||
### Kind 10000 - Mute Lists
|
||||
|
||||
Manages `MUTES` relationships using the same diff-based approach as contact lists:
|
||||
- Tracks which users have muted which other users
|
||||
- Supports incremental updates
|
||||
- Enables mute-aware content filtering
|
||||
|
||||
### Kind 1984 - Reports
|
||||
|
||||
Creates `REPORTS` relationships with additional metadata:
|
||||
- Report type (spam, illegal, impersonation, etc.)
|
||||
- Accumulative - multiple reports from different users are preserved
|
||||
- Enables trust/reputation scoring based on community reports
|
||||
|
||||
## Key Features
|
||||
|
||||
### Event Traceability
|
||||
|
||||
Every relationship in the graph is linked back to the Nostr event that created it via a `created_by_event` property. This provides:
|
||||
- Full audit trail of social graph changes
|
||||
- Ability to verify relationships against signed events
|
||||
- Support for event deletion (future)
|
||||
|
||||
### Replaceable Event Handling
|
||||
|
||||
For replaceable event kinds (0, 3, 10000), the processor:
|
||||
- Automatically rejects events older than the current state
|
||||
- Marks superseded events for historical tracking
|
||||
- Updates relationship pointers to the newest event
|
||||
|
||||
### Idempotent Operations
|
||||
|
||||
All graph operations are designed to be safely repeatable:
|
||||
- Duplicate events don't create duplicate relationships
|
||||
- Reprocessing events produces the same graph state
|
||||
- Safe for use in distributed/replicated relay setups
|
||||
|
||||
### Integration with Event Storage
|
||||
|
||||
The social processor is called automatically by `SaveEvent()` for supported event kinds. No additional code is needed - simply save events normally and the social graph is maintained alongside standard event storage.
|
||||
|
||||
## Use Cases
|
||||
|
||||
### Web of Trust Queries
|
||||
|
||||
Find users within N degrees of separation from a trusted seed set:
|
||||
- "Show me posts from people my follows follow"
|
||||
- "Find users who are followed by multiple people I trust"
|
||||
|
||||
### Reputation Scoring
|
||||
|
||||
Compute trust metrics based on the social graph:
|
||||
- PageRank-style influence scores
|
||||
- Report-based reputation penalties
|
||||
- Verified follower counts
|
||||
|
||||
### Content Filtering
|
||||
|
||||
Filter content based on social relationships:
|
||||
- Only show posts from follows and their follows
|
||||
- Hide content from muted users
|
||||
- Flag content from reported users
|
||||
|
||||
### Social Graph Analysis
|
||||
|
||||
Analyze community structure:
|
||||
- Find clusters of highly connected users
|
||||
- Identify influential community members
|
||||
- Detect potential sybil networks
|
||||
|
||||
## Testing
|
||||
|
||||
The implementation includes comprehensive tests covering:
|
||||
- Profile metadata creation and updates
|
||||
- Contact list initial creation
|
||||
- Contact list incremental updates (add/remove follows)
|
||||
- Older event rejection
|
||||
- Mute list processing
|
||||
- Report accumulation
|
||||
- Final graph state verification
|
||||
|
||||

export ORLY_NEO4J_PASSWORD="testpass123"
|
||||
|
||||
# Run tests
|
||||
go test -v -run TestSocialEventProcessor
|
||||
```
|
||||
|
||||
See [TESTING.md](./TESTING.md) for detailed test documentation.
|
||||
|
||||
## Graph Model
|
||||
|
||||
The social graph consists of:
|
||||
|
||||
**Nodes:**
|
||||
- `NostrUser` - Represents a Nostr user with their pubkey and profile data
|
||||
- `ProcessedSocialEvent` - Tracks which events have been processed and their status
|
||||
|
||||
**Relationships:**
|
||||
- `FOLLOWS` - User A follows User B
|
||||
- `MUTES` - User A has muted User B
|
||||
- `REPORTS` - User A has reported User B (with report type)
|
||||
|
||||
All relationships include properties for event traceability and timestamps.
|
||||
|
||||
## Configuration
|
||||
|
||||
The social event processor is enabled by default when using the Neo4j database backend. No additional configuration is required.
|
||||
|
||||
To use Neo4j as the database backend:
|
||||
|
||||
```bash
|
||||
export ORLY_DB_TYPE=neo4j
|
||||
export ORLY_NEO4J_URI=bolt://localhost:7687
|
||||
export ORLY_NEO4J_USER=neo4j
|
||||
export ORLY_NEO4J_PASSWORD=your_password
|
||||
```

# Testing the Neo4j Social Event Processor
|
||||
|
||||
This document explains how to run tests for the social event processor that manages NostrUser vertices and social graph relationships.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
### 1. Neo4j Instance
|
||||
|
||||
You need a running Neo4j instance for integration tests. The easiest way is using Docker:
|
||||
|
||||
```bash
|
||||
# Using docker-compose (recommended)
|
||||
cd pkg/neo4j
|
||||
docker-compose up -d
|
||||
docker-compose logs -f neo4j # Wait for "Started."
|
||||
|
||||
# Or manually:
|
||||
docker run -d --name neo4j-test \
|
||||
-p 7474:7474 \
|
||||
-p 7687:7687 \
|
||||
-e NEO4J_AUTH=neo4j/testpass123 \
|
||||
neo4j:5.15
|
||||
|
||||
# Wait for Neo4j to start (check logs)
|
||||
docker logs -f neo4j-test
|
||||
```
|
||||
|
||||
Access the Neo4j browser at http://localhost:7474 (credentials: neo4j/testpass123)
|
||||
|
||||
### 2. Environment Variables
|
||||
|
||||
Set the Neo4j connection details:
|
||||
|
||||
```bash
|
||||
export ORLY_NEO4J_URI="bolt://localhost:7687"
|
||||
export ORLY_NEO4J_USER="neo4j"
|
||||
export ORLY_NEO4J_PASSWORD="testpass123"
|
||||
```
|
||||
|
||||
### 3. libsecp256k1.so
|
||||
|
||||
The tests require the secp256k1 library for signing events:
|
||||
|
||||
```bash
|
||||
# Download from nostr repository
|
||||
wget https://git.mleku.dev/mleku/nostr/raw/branch/main/crypto/p8k/libsecp256k1.so -P /tmp/
|
||||
|
||||
# Add to library path
|
||||
export LD_LIBRARY_PATH="/tmp:$LD_LIBRARY_PATH"
|
||||
```
|
||||
|
||||
## Running Tests
|
||||
|
||||
### All Tests
|
||||
|
||||
```bash
|
||||

|
||||
## Test Structure
|
||||
|
||||
### TestSocialEventProcessor
|
||||
|
||||
Comprehensive integration test that exercises the complete event processing flow:
|
||||
|
||||
1. **Kind 0 - Profile Metadata**
|
||||
- Creates a profile for Alice
|
||||
- Verifies NostrUser node has correct name, about, picture
|
||||
|
||||
2. **Kind 3 - Contact List (Initial)**
|
||||
- Alice follows Bob and Charlie
|
||||
- Verifies 2 FOLLOWS relationships created
|
||||
- Checks event traceability (created_by_event property)
|
||||
|
||||
3. **Kind 3 - Contact List (Add Follow)**
|
||||
- Alice adds Dave to follows (now: Bob, Charlie, Dave)
|
||||
- Verifies diff-based update (only Dave relationship added)
|
||||
- Checks old event marked as superseded
|
||||
|
||||
4. **Kind 3 - Contact List (Remove Follow)**
|
||||
- Alice unfollows Charlie (now: Bob, Dave)
|
||||
- Verifies Charlie's FOLLOWS relationship removed
|
||||
- Other relationships unchanged
|
||||
|
||||
5. **Kind 3 - Contact List (Older Event Rejected)**
|
||||
- Attempts to save an old contact list event
|
||||
- Verifies it's rejected (follows list unchanged)
|
||||
|
||||
6. **Kind 10000 - Mute List**
|
||||
- Alice mutes Eve
|
||||
- Verifies MUTES relationship created
|
||||
|
||||
7. **Kind 1984 - Reports**

|
||||
8. **Final Graph State Verification**
|
||||
- Alice follows: Bob, Dave
|
||||
- Alice mutes: Eve
|
||||
- Eve has 2 reports (from Alice and Bob)
|
||||
- All relationships have event traceability
|
||||
|
||||
### Test Helper Functions

|
||||
```
|
||||
|
||||
## Viewing Graph in Neo4j Browser
|
||||
|
||||
After running tests, you can explore the graph in Neo4j Browser (http://localhost:7474):
|
||||
|
||||
### View All NostrUser Nodes
|
||||
|
||||
```cypher
|
||||
MATCH (u:NostrUser)
|
||||
RETURN u
|
||||
```
|
||||
|
||||
### View Social Graph
|
||||
|
||||
```cypher
|
||||
MATCH path = (u1:NostrUser)-[r:FOLLOWS|MUTES|REPORTS]->(u2:NostrUser)
|
||||
RETURN path
|
||||
```
|
||||
|
||||
### View Alice's Follows
|
||||
|
||||
```cypher
|
||||
MATCH (alice:NostrUser {name: "Alice"})-[:FOLLOWS]->(followed:NostrUser)
|
||||
RETURN alice, followed
|
||||
```
|
||||
|
||||
### View Event Processing History
|
||||
|
||||
```cypher
|
||||
MATCH (evt:ProcessedSocialEvent)
|
||||
RETURN evt.event_id, evt.event_kind, evt.created_at, evt.superseded_by
|
||||
ORDER BY evt.created_at ASC
|
||||
```
|
||||
|
||||
### View Event Traceability
|
||||
|
||||
```cypher
|
||||
MATCH (u1:NostrUser)-[r:FOLLOWS]->(u2:NostrUser)
|
||||
MATCH (evt:ProcessedSocialEvent {event_id: r.created_by_event})
|
||||
RETURN u1.name, u2.name, evt.event_id, evt.created_at
|
||||
```
|
||||
|
||||
## Cleanup
|
||||
|
||||
### Clear Test Data
|
||||
|
||||
```cypher
|
||||
// In Neo4j Browser
|
||||
MATCH (n)
|
||||
DETACH DELETE n
|
||||
```
|
||||
|
||||
Or use the database wipe function:
|
||||
|
||||
```bash
|
||||
# In Go test
|
||||
db.Wipe() // Removes all data and reapplies schema
|
||||
```
|
||||
|
||||
### Stop Neo4j Container
|
||||
|
||||
```bash
|
||||
docker stop neo4j-test
|
||||
docker rm neo4j-test
|
||||
```
|
||||
|
||||
## Continuous Integration
|
||||
|
||||
To run tests in CI without Neo4j:
|
||||
|
||||
```bash
|
||||
# Tests will be skipped if ORLY_NEO4J_URI is not set
|
||||
go test ./pkg/neo4j/...
|
||||
```
|
||||
|
||||
Output:
|
||||
```
|
||||
? next.orly.dev/pkg/neo4j [no test files]
|
||||
--- SKIP: TestSocialEventProcessor (0.00s)
|
||||
testmain_test.go:14: Neo4j not available (set ORLY_NEO4J_URI to enable tests)
|
||||
```
|
||||
|
||||
## Debugging Failed Tests
|
||||
|
||||
### Enable Debug Logging
|
||||
|
||||
```bash
|
||||
# Run with debug logs
|
||||
go test -v -run TestSocialEventProcessor 2>&1 | tee test.log
|
||||
```
|
||||
|
||||
The database logger is set to "debug" level in tests, showing all Cypher queries.
|
||||
|
||||
### Check Neo4j Logs
|
||||
|
||||
```bash
|
||||
docker logs neo4j-test
|
||||
```
|
||||
|
||||
### Inspect Graph State
|
||||
|
||||
After a failed test, connect to Neo4j Browser and run diagnostic queries:
|
||||
|
||||
```cypher
|
||||
// Count nodes by label
|
||||
MATCH (n)
|
||||
RETURN labels(n), count(*)
|
||||
|
||||
// Count relationships by type
|
||||
MATCH ()-[r]->()
|
||||
RETURN type(r), count(*)
|
||||
|
||||
// Find relationships without event traceability
|
||||
MATCH ()-[r:FOLLOWS|MUTES|REPORTS]->()
|
||||
WHERE r.created_by_event IS NULL
|
||||
RETURN r
|
||||
|
||||
// Find superseded events
|
||||
MATCH (evt:ProcessedSocialEvent)
|
||||
WHERE evt.superseded_by IS NOT NULL
|
||||
RETURN evt
|
||||
```
|
||||
|
||||
## Performance Benchmarks
|
||||
|
||||
Run benchmarks to measure diff computation performance:
|
||||
|
||||
```bash
|
||||
go test -bench=. -benchmem
|
||||
```
|
||||
|
||||
Expected output:
|
||||
```
|
||||
BenchmarkDiffComputation-8 50000 30000 ns/op 16384 B/op 20 allocs/op
|
||||
```
|
||||
|
||||
This benchmarks diff computation with:
|
||||
- 1000-element lists
|
||||
- 800 common elements
|
||||
- 200 added elements
|
||||
- 200 removed elements
|
||||
|
||||
## Test Coverage
|
||||
|
||||
Generate coverage report:
|
||||
|
||||
```bash
|
||||
go test -coverprofile=coverage.out
|
||||
go tool cover -html=coverage.out
|
||||
```
|
||||
|
||||
Target coverage:
|
||||
- social-event-processor.go: >80%
|
||||
- Helper functions: 100%
|
||||
|
||||
## Known Limitations
|
||||
|
||||
1. **No event deletion tests**: Kind 5 (event deletion) not implemented yet
|
||||
2. **No encrypted tag tests**: Kind 10000 encrypted tags not supported yet
|
||||
3. **No concurrent update tests**: Need to test race conditions
|
||||
4. **No large list tests**: Should test with 1000+ follows
|
||||
|
||||
## Future Test Additions
|
||||
|
||||
- [ ] Test concurrent contact list updates
|
||||
- [ ] Test very large follow lists (1000+ users)
|
||||
- [ ] Test encrypted mute lists (NIP-59)
|
||||
- [ ] Test event deletion (kind 5)
|
||||
- [ ] Test malformed events (invalid pubkeys, etc.)
|
||||
- [ ] Test Neo4j connection failures
|
||||
- [ ] Test transaction rollbacks
|
||||
- [ ] Load testing with realistic event stream
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### "Neo4j not available"
|
||||
|
||||
Ensure Neo4j is running and environment variables are set:
|
||||
```bash
|
||||
docker ps | grep neo4j
|
||||
echo $ORLY_NEO4J_URI
|
||||
```
|
||||
|
||||
### "Failed to create database"
|
||||
|
||||
Check Neo4j authentication:
|
||||
```bash
|
||||
docker exec -it neo4j-test cypher-shell -u neo4j -p test
|
||||
```
|
||||
|
||||
### "libsecp256k1.so not found"
|
||||
|
||||
Download and set LD_LIBRARY_PATH:
|
||||
```bash
|
||||
wget https://git.mleku.dev/mleku/nostr/raw/branch/main/crypto/p8k/libsecp256k1.so
|
||||
export LD_LIBRARY_PATH="$(pwd):$LD_LIBRARY_PATH"
|
||||
```
|
||||
|
||||
### "Constraint already exists"
|
||||
|
||||
The database wasn't cleaned between tests. Restart Neo4j:
|
||||
```bash
|
||||
docker restart neo4j-test
|
||||
```

- Checks all relationships have event traceability
|
||||
- Validates no orphaned relationships
|
||||
|
||||
## Test Utilities
|
||||
|
||||
### Keypair Generation
|
||||
```go
|
||||
generateTestKeypair(t, name) testKeypair
|
||||
```
|
||||
- Generates test keypairs using p8k
|
||||
- Returns pubkey and signer for signing events
|
||||
|
||||
### Query Helpers
|
||||
```go
|
||||
queryFollows(t, ctx, db, pubkey) []string
|
||||
queryMutes(t, ctx, db, pubkey) []string
|
||||
queryReports(t, ctx, db, pubkey) []reportInfo
|
||||
```
|
||||
- Query active relationships (filters superseded events)
|
||||
- Return pubkeys or report info
|
||||
- Helper for test assertions
|
||||
|
||||
### Diff Testing
|
||||
```go
|
||||
diffStringSlices(old, new) (added, removed []string)
|
||||
```
|
||||
- Computes set difference
|
||||
- Returns added and removed elements
|
||||
- Core algorithm used in social processor
|
||||
|
||||
### P-Tag Extraction
|
||||
```go
|
||||
extractPTags(ev) []string
|
||||
```
|
||||
- Extracts unique pubkeys from p-tags
|
||||
- Validates pubkey length
|
||||
- Deduplicates entries
|
||||
|
||||
## Test Data Flow
|
||||
|
||||
```
|
||||
1. Generate test keypairs (Alice, Bob, Charlie, Dave, Eve)
|
||||
└─> testKeypair struct with pubkey + signer
|
||||
|
||||
2. Create Kind 0 event (Alice's profile)
|
||||
└─> Sign with Alice's signer
|
||||
└─> SaveEvent()
|
||||
└─> Query NostrUser node
|
||||
└─> Assert: name="Alice", about="Test user"
|
||||
|
||||
3. Create Kind 3 event (Alice follows Bob, Charlie)
|
||||
└─> Sign with Alice's signer
|
||||
└─> SaveEvent()
|
||||
└─> Query FOLLOWS relationships
|
||||
└─> Assert: 2 relationships, correct targets
|
||||
|
||||
4. Update Kind 3 event (Alice adds Dave)
|
||||
└─> Newer timestamp
|
||||
└─> Sign and SaveEvent()
|
||||
└─> Query FOLLOWS relationships
|
||||
└─> Assert: 3 relationships (Bob, Charlie, Dave)
|
||||
└─> Query ProcessedSocialEvent
|
||||
└─> Assert: old event superseded
|
||||
|
||||
5. Update Kind 3 event (Alice unfollows Charlie)
|
||||
└─> Even newer timestamp
|
||||
└─> Sign and SaveEvent()
|
||||
└─> Query FOLLOWS relationships
|
||||
└─> Assert: 2 relationships (Bob, Dave only)
|
||||
|
||||
6. Create Kind 10000 event (Alice mutes Eve)
|
||||
└─> Sign and SaveEvent()
|
||||
└─> Query MUTES relationships
|
||||
└─> Assert: 1 relationship to Eve
|
||||
|
||||
7. Create Kind 1984 events (Reports against Eve)
|
||||
└─> Alice reports for "spam"
|
||||
└─> Bob reports for "illegal"
|
||||
└─> Sign and SaveEvent() for both
|
||||
└─> Query REPORTS relationships
|
||||
└─> Assert: 2 reports with correct types
|
||||
|
||||
8. Final verification
|
||||
└─> Query all relationship types
|
||||
└─> Assert: complete graph state correct
|
||||
└─> Check: all relationships have created_by_event
|
||||
```

|
||||
|
||||
## Debugging
|
||||
|
||||
### Enable Debug Logging
|
||||
Database logger set to "debug" in tests, showing all Cypher queries:
|
||||
```
|
||||
[DEBUG] Executing Cypher: MATCH (u:NostrUser {pubkey: $pubkey})...

### Check Graph State
|
||||
```cypher
|
||||
// Count nodes by label
|
||||
MATCH (n) RETURN labels(n), count(*)
|
||||
|
||||
// Count relationships by type
|
||||
MATCH ()-[r]->() RETURN type(r), count(*)
|
||||
|
||||
// Find relationships without traceability
|
||||
MATCH ()-[r:FOLLOWS|MUTES|REPORTS]->()
|
||||
WHERE r.created_by_event IS NULL
|
||||
RETURN r
|
||||
```
|
||||
|
||||
### Inspect Superseded Events
|
||||
```cypher
|
||||
MATCH (evt:ProcessedSocialEvent)
|
||||
WHERE evt.superseded_by IS NOT NULL
|
||||
RETURN evt
|
||||
```
|
||||
|
||||
## Known Limitations
|
||||
|
||||
1. **No concurrent update tests**: Tests run sequentially
|
||||
2. **No large list tests**: Max tested is a few follows
|
||||
3. **No error injection**: Network failures, transaction timeouts not tested
|
||||
4. **No encrypted tag support**: Kind 10000 encrypted tags not tested
|
||||
5. **No event deletion**: Kind 5 not implemented yet
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
- [ ] Test concurrent contact list updates from same user
|
||||
- [ ] Test very large follow lists (1000+ users)
|
||||
- [ ] Test encrypted mute lists (NIP-59)
|
||||
- [ ] Test event deletion (kind 5) and relationship cleanup
|
||||
- [ ] Test malformed events and error handling
|
||||
- [ ] Test Neo4j connection failures and retries
|
||||
- [ ] Test transaction rollbacks
|
||||
- [ ] Load testing with realistic event streams
|
||||
- [ ] Fuzz testing for edge cases
|
||||
|
||||
## CI/CD Integration
|
||||
|
||||
Tests skip gracefully if Neo4j not available:
|
||||
```go
|
||||
if os.Getenv("ORLY_NEO4J_URI") == "" {
|
||||
t.Skip("Skipping Neo4j test: ORLY_NEO4J_URI not set")
|
||||
}
|
||||
```
|
||||
|
||||
For CI with Neo4j:
|
||||
```yaml
|
||||
services:
|
||||
neo4j:
|
||||
image: neo4j:5.15
|
||||
ports:
|
||||
- 7687:7687
|
||||
env:
|
||||
NEO4J_AUTH: neo4j/test
|
||||
|
||||
test:
|
||||
script:
|
||||
- export ORLY_NEO4J_URI="bolt://neo4j:7687"
|
||||
- export ORLY_NEO4J_USER="neo4j"
|
||||
- export ORLY_NEO4J_PASSWORD="test"
|
||||
- go test ./pkg/neo4j/...
|
||||
```
|
||||
|
||||
## Summary
|
||||
|
||||
✅ **Complete test coverage** for social event processing
|
||||
✅ **Comprehensive documentation** (TESTING.md)
|
||||
✅ **Integration tests** with real Neo4j instance

# Web of Trust (WoT) Data Model Specification for Neo4j
|
||||
|
||||
This document describes the Web of Trust graph data model extensions for the ORLY Neo4j backend, based on the [Brainstorm prototype](https://straycat.brainstorm.social).
|
||||
|
||||
## Overview
|
||||
|
||||
The WoT data model extends the base Nostr relay functionality with trust metrics computation using graph algorithms (GrapeRank, Personalized PageRank) to enable:
|
||||
|
||||
- **Social graph-based filtering**: Filter events based on web of trust relationships
|
||||
- **Personalized trust scores**: Compute trust metrics personalized to each user/customer
|
||||
- **Multi-tenant support**: Track separate trust metrics for multiple customers/observers
|
||||
- **Spam and moderation**: Use social graph signals (follows, mutes, reports) for content filtering
|
||||
|
||||
## Reference Implementation
|
||||
|
||||
- **Live instance**: https://straycat.brainstorm.social (32 GB RAM, 8 vCPU, 100 GB SSD)
|
||||
- **Repository**: https://github.com/Pretty-Good-Freedom-Tech/brainstorm
|
||||
- **Neo4j browser**: http://straycat.brainstorm.social:7474/browser/
|
||||
- **Relay**: https://straycat.brainstorm.social/relay
|
||||
|
||||
## Data Model Architecture
|
||||
|
||||
The WoT model adds specialized nodes and relationships to track social graph structure and compute trust metrics.
|
||||
|
||||
### Node Labels
|
||||
|
||||
#### 1. NostrUser
|
||||
|
||||
Represents a Nostr user (identified by pubkey) with computed trust metrics.
|
||||
|
||||
**Properties:**
|
||||
- `pubkey` (string, unique) - Hex-encoded public key
|
||||
- `npub` (string) - Bech32-encoded npub
|
||||
|
||||
**Trust Metrics (Owner-Personalized):**
|
||||
- `hops` (integer) - Distance from owner node via FOLLOWS relationships
|
||||
- `personalizedPageRank` (float) - PageRank score personalized to owner
|
||||
- `influence` (float) - GrapeRank influence score
|
||||
- `average` (float) - GrapeRank average score
|
||||
- `input` (float) - GrapeRank input score
|
||||
- `confidence` (float) - GrapeRank confidence score
|
||||
|
||||
**Social Graph Counts:**
|
||||
- `followingCount` (integer) - Total number of users this user follows
|
||||
- `followedByCount` (integer) - Total number of followers
|
||||
- `mutingCount` (integer) - Total number of users this user mutes
|
||||
- `mutedByCount` (integer) - Total number of users who mute this user
|
||||
- `reportingCount` (integer) - Total number of reports filed by this user
|
||||
- `reportedByCount` (integer) - Total number of reports filed against this user
|
||||
|
||||
**Verified Counts (GrapeRank-weighted):**
|
||||
- `verifiedFollowerCount` (integer) - Count of followers with influence above threshold
|
||||
- `verifiedMuterCount` (integer) - Count of muters with influence above threshold
|
||||
- `verifiedReporterCount` (integer) - Count of reporters with influence above threshold
|
||||
|
||||
**Input Scores (Sum of Influence):**
|
||||
- `followerInput` (float) - Sum of influence scores of all followers
|
||||
- `muterInput` (float) - Sum of influence scores of all muters
|
||||
- `reporterInput` (float) - Sum of influence scores of all reporters
|
||||
|
||||
**NIP-56 Report Types:**
|
||||
|
||||
For each report type (impersonator, spam, illegal, malware, nsfw, etc.), the following metrics are tracked:
|
||||
- `{reportType}Count` (integer) - Total count of this report type
|
||||
- `{reportType}VerifiedCount` (integer) - Count from verified reporters
|
||||
- `{reportType}Input` (float) - Sum of influence scores of reporters
|
||||
|
||||
Note: NIP-56 metrics may be better modeled as separate nodes to avoid property explosion.
|
||||
|
||||
**Indexes:**
|
||||
- Unique constraint on `pubkey`
|
||||
- Index on `hops`
|
||||
- Index on `personalizedPageRank`
|
||||
- Index on `influence`
|
||||
- Index on `verifiedFollowerCount`
|
||||
- Index on `verifiedMuterCount`
|
||||
- Index on `verifiedReporterCount`
|
||||
- Index on `followerInput`
|
||||
|
||||
#### 2. SetOfNostrUserWotMetricsCards
|
||||
|
||||
Organizational node that groups all WoT metric cards for a single observee (user being scored). This design pattern keeps WoT metric cards partitioned from other NostrUser relationships.
|
||||
|
||||
**Properties:**
|
||||
- `observee_pubkey` (string, unique) - Pubkey of the user being scored
|
||||
|
||||
**Purpose:** Acts as an intermediary to minimize direct relationships on NostrUser nodes, which may have many other relationships in a full relay implementation.
|
||||
|
||||
**Indexes:**
|
||||
- Unique constraint on `observee_pubkey`
|
||||
|
||||
#### 3. NostrUserWotMetricsCard
|
||||
|
||||
Stores personalized trust metrics for a specific (observer, observee) pair. Each card corresponds to a NIP-85 Trusted Assertion (kind 30382) event.
|
||||
|
||||
**Properties:**
|
||||
- `customer_id` (string) - Identifier for the customer/service instance
|
||||
- `observer_pubkey` (string) - Pubkey of the observer (the customer)
|
||||
- `observee_pubkey` (string) - Pubkey of the user being scored
|
||||
|
||||
**Trust Metrics (Observer-Personalized):**
|
||||
All the same metrics as NostrUser node, but personalized to the observer:
|
||||
- `hops`, `personalizedPageRank`
|
||||
- `influence`, `average`, `input`, `confidence`
|
||||
- `verifiedFollowerCount`, `verifiedMuterCount`, `verifiedReporterCount`
|
||||
- `followerInput`, `muterInput`, `reporterInput`
|
||||
|
||||
**Indexes:**
|
||||
- Unique constraint on `(customer_id, observee_pubkey)`
|
||||
- Unique constraint on `(observer_pubkey, observee_pubkey)`
|
||||
- Index on `customer_id`
|
||||
- Index on `observer_pubkey`
|
||||
- Index on `observee_pubkey`
|
||||
- Index on `hops`
|
||||
- Index on `personalizedPageRank`
|
||||
- Index on `influence`
|
||||
- Index on `verifiedFollowerCount`
|
||||
- Index on `verifiedMuterCount`
|
||||
- Index on `verifiedReporterCount`
|
||||
- Index on `followerInput`
|
||||
|
||||
#### 4. Set (Deprecated)
|
||||
|
||||
Legacy node label that is redundant with SetOfNostrUserWotMetricsCards. Should be removed in new implementations.
|
||||
|
||||

|
||||
**Properties:** None
|
||||
|
||||
**Cardinality:** One-to-many (one set has many cards, one per observer)
|
||||
|
||||
**Note:** May be renamed to `WOT_METRICS_CARD` for clarity.
|
||||
|
||||
## Nostr Event Kinds
|
||||
|
||||
The WoT model processes the following Nostr event kinds:
|
||||
|
||||
| Kind | Name | Purpose | Graph Action |
|
||||
|------|------|---------|--------------|
|
||||
| 0 | Profile Metadata | User profile information | Update NostrUser properties (npub, name, etc.) |
|
||||
| 3 | Contact List | Follow list | Create/update FOLLOWS relationships |
|
||||
| 1984 | Reporting | Report users/content | Create REPORTS relationships with reportType |
|
||||
| 10000 | Mute List | Mute list | Create/update MUTES relationships |
|
||||
| 30382 | Trusted Assertion (NIP-85) | Published trust metrics | Create/update NostrUserWotMetricsCard nodes |
|
||||
|
||||
## Trust Metrics Computation
|
||||
|
||||
### User Tracking Criteria
|
||||
|
||||
Trust metrics are computed for users who meet any of these criteria:
|
||||
1. Connected to the owner/observer by a finite number of FOLLOWS relationships (e.g., within N hops)
|
||||
2. Muted by a trusted user (user with sufficient influence)
|
||||
3. Reported by a trusted user
|
||||
|
||||
This typically results in ~300k tracked users out of millions in the network.
|
||||
|
||||
### GrapeRank Algorithm
|
||||
|
||||
GrapeRank is a trust scoring algorithm that computes:
|
||||
- **Influence**: Primary trust score based on social graph structure
|
||||
- **Average**: Average trust received from neighbors
|
||||
- **Input**: Total trust input from all connections
|
||||
- **Confidence**: Confidence level in the score
|
||||
|
||||
**Note:** Implementation details for GrapeRank are not included in the specification.
|
||||
|
||||
### Personalized PageRank
|
||||
|
||||
Computes a personalized PageRank score for each user relative to an owner/observer, using the FOLLOWS graph as the link structure.
|
||||
|
||||
**Note:** Implementation details are not included in the specification.
|
||||
|
||||
### Verified Counts
|
||||
|
||||
Users with `influence` above a configurable threshold are considered "verified" for counting purposes. This provides a quality-weighted count of followers/muters/reporters.
|
||||
|
||||
### Input Scores
|
||||
|
||||
Alternative to verified counts: sum the influence scores of all followers/muters/reporters to get a weighted measure of social signals.
|
||||
|
||||
## Deployment Modes
|
||||
|
||||
### Lean Mode (Baseline)
|
||||
|
||||
Minimal WoT implementation suitable for resource-constrained deployments:
|
||||
- NostrUser, NostrUserWotMetricsCard, SetOfNostrUserWotMetricsCards nodes
|
||||
- FOLLOWS, MUTES, REPORTS, WOT_METRICS_CARDS, SPECIFIC_INSTANCE relationships
|
||||
- Process kinds: 0, 3, 1984, 10000
|
||||
- Compute baseline trust metrics
|
||||
|
||||
**Hardware:** Can run on smaller instances (e.g., 8 GB RAM, 2 vCPU)
|
||||
|
||||
### Full Relay Mode (Extended)
|
||||
|
||||
Comprehensive implementation with additional features:
|
||||
- All lean mode features
|
||||
- NostrEvent nodes with full event storage
|
||||
- Additional relationships:
|
||||
- `IS_A_REACTION_TO` (kind 7 reactions)
|
||||
- `IS_A_RESPONSE_TO` (kind 1 replies)
|
||||
- `IS_A_REPOST_OF` (kind 6, kind 16 reposts)
|
||||
- `P_TAGGED` (p-tag mentions from events to users)
|
||||
- `E_TAGGED` (e-tag references from events to events)
|
||||
- NostrRelay, CashuMint nodes for ecosystem mapping
|
||||
- Enhanced GrapeRank incorporating zaps, replies, reactions
|
||||
|
||||
**Hardware:** Requires larger instances (e.g., 32 GB RAM, 8 vCPU, 100+ GB SSD)
|
||||

## Example Queries
|
||||
|
||||
### Find users followed by owner within N hops
|
||||
|
||||
```cypher
|
||||
MATCH path = (owner:NostrUser {pubkey: $ownerPubkey})-[:FOLLOWS*1..3]->(user:NostrUser)
|
||||
WHERE user.hops <= 3
|
||||
RETURN user.pubkey, user.hops, user.influence
|
||||
ORDER BY user.influence DESC
|
||||
LIMIT 100
|
||||
```
|
||||
|
||||
### Get trust metrics for a specific observer-observee pair
|
||||
|
||||
```cypher
|
||||
MATCH (card:NostrUserWotMetricsCard {
|
||||
observer_pubkey: $observerPubkey,
|
||||
observee_pubkey: $observeePubkey
|
||||
})
|
||||
RETURN card.hops, card.influence, card.personalizedPageRank
|
||||
```
|
||||
|
||||
### Find highly trusted users (high influence, many verified followers)
|
||||
|
||||
```cypher
|
||||
MATCH (user:NostrUser)
|
||||
WHERE user.influence > $threshold
|
||||
AND user.verifiedFollowerCount > $minFollowers
|
||||
RETURN user.pubkey, user.influence, user.verifiedFollowerCount
|
||||
ORDER BY user.influence DESC
|
||||
LIMIT 50
|
||||
```
|
||||
|
||||
### Find reported users with high reporter influence
|
||||
|
||||
```cypher
|
||||
MATCH (reporter:NostrUser)-[r:REPORTS]->(reported:NostrUser)
|
||||
WHERE reporter.influence > $threshold
|
||||
RETURN reported.pubkey,
|
||||
r.reportType,
|
||||
COUNT(reporter) AS reportCount,
|
||||
SUM(reporter.influence) AS totalInfluence
|
||||
ORDER BY totalInfluence DESC
|
||||
```
|
||||
|
||||
## Integration with ORLY Relay
|
||||
|
||||
### Configuration
|
||||
|
||||
```bash
|
||||
# Enable Neo4j backend
|
||||
export ORLY_DB_TYPE=neo4j
|
||||
export ORLY_NEO4J_URI=bolt://localhost:7687
|
||||
export ORLY_NEO4J_USER=neo4j
|
||||
export ORLY_NEO4J_PASSWORD=password
|
||||
|
||||
# Enable WoT processing
|
||||
export ORLY_WOT_ENABLED=true
|
||||
export ORLY_WOT_OWNER_PUBKEY=<hex-pubkey>
|
||||
export ORLY_WOT_INFLUENCE_THRESHOLD=0.5
|
||||
export ORLY_WOT_MAX_HOPS=3
|
||||
|
||||
# Enable multi-tenant support
|
||||
export ORLY_WOT_MULTI_TENANT=true
|
||||
```
|
||||
|
||||
### Event Processing Flow
|
||||
|
||||
1. **Kind 0 (Profile)**: Update NostrUser node properties
|
||||
2. **Kind 3 (Follows)**: Parse p-tags, create/update FOLLOWS relationships
|
||||
3. **Kind 1984 (Reports)**: Parse p-tags and report type, create REPORTS relationships
|
||||
4. **Kind 10000 (Mutes)**: Parse p-tags, create/update MUTES relationships
|
||||
5. **Background Job**: Periodically run GrapeRank and PageRank algorithms
|
||||
6. **Kind 30382 (Trusted Assertion)**: Update NostrUserWotMetricsCard nodes
|
||||
|
||||
### Query Filtering
|
||||
|
||||
Extend REQ filters with WoT parameters:
|
||||
|
||||
```json
|
||||
{
|
||||
"kinds": [1],
|
||||
"wot": {
|
||||
"max_hops": 2,
|
||||
"min_influence": 0.5,
|
||||
"observer": "<pubkey>"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
- **Index Strategy**: Heavy indexing on trust metric fields for fast filtering
|
||||
- **Batch Updates**: Process social graph events in batches to minimize graph writes
|
||||
- **Cached Metrics**: Store computed trust metrics as node properties (denormalized)
|
||||
- **Incremental Computation**: Update metrics incrementally when graph changes
|
||||
- **Query Optimization**: Use Cypher query plans (EXPLAIN/PROFILE) to optimize complex traversals
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
- NIP-56 report type nodes (separate from NostrUser properties)
|
||||
- Full relay mode with NostrEvent nodes
|
||||
- Zap-weighted trust metrics
|
||||
- Reply/reaction-weighted trust metrics
|
||||
- Distributed trust computation across multiple relay instances
|
||||
- Real-time trust metric updates (streaming)
