Add Blossom bandwidth limiting and tune rate limiters (v0.49.0)
...
Go / build-and-release (push) Has been cancelled
- Add token-bucket bandwidth rate limiting for Blossom uploads
- ORLY_BLOSSOM_RATE_LIMIT enables limiting (default: false)
- ORLY_BLOSSOM_DAILY_LIMIT_MB sets daily limit (default: 10MB)
- ORLY_BLOSSOM_BURST_LIMIT_MB sets burst cap (default: 50MB)
- Followed users, admins, owners are exempt (unlimited)
- Change emergency mode throttling from exponential to linear scaling
- Old: 16x multiplier at emergency threshold entry
- New: 1x at threshold, +1x per 20% excess pressure
- Reduce follows ACL throttle increment from 200ms to 25ms per event
- Update dependencies
Files modified:
- app/blossom.go: Pass rate limit config to blossom server
- app/config/config.go: Add Blossom rate limit config options
- pkg/blossom/ratelimit.go: New bandwidth limiter implementation
- pkg/blossom/server.go: Add rate limiter integration
- pkg/blossom/handlers.go: Check rate limits on upload/mirror/media
- pkg/ratelimit/limiter.go: Linear emergency throttling
- pkg/acl/follows.go: Reduce default throttle increment

Add Cashu blind signature access tokens (NIP-XX draft)
...
Implements privacy-preserving bearer tokens for relay access control using
Cashu-style blind signatures. Tokens prove whitelist membership without
linking issuance to usage.
Features:
- BDHKE crypto primitives (HashToCurve, Blind, Sign, Unblind, Verify)
- Keyset management with weekly rotation
- Token format with kind permissions and scope isolation
- Generic issuer/verifier with pluggable authorization
- HTTP endpoints: POST /cashu/mint, GET /cashu/keysets, GET /cashu/info
- ACL adapter bridging ORLY's access control to Cashu AuthzChecker
- Stateless revocation via ACL re-check on each token use
- Two-token rotation for seamless renewal (max 2 weeks after blacklist)
Configuration:
- ORLY_CASHU_ENABLED: Enable Cashu tokens
- ORLY_CASHU_TOKEN_TTL: Token validity (default: 1 week)
- ORLY_CASHU_SCOPES: Allowed scopes (relay, nip46, blossom, api)
- ORLY_CASHU_REAUTHORIZE: Re-check ACL on each verification
Files:
- pkg/cashu/bdhke/: Core blind signature cryptography
- pkg/cashu/keyset/: Keyset management and rotation
- pkg/cashu/token/: Token format with kind permissions
- pkg/cashu/issuer/: Token issuance with authorization
- pkg/cashu/verifier/: Token verification with middleware
- pkg/interfaces/cashu/: AuthzChecker, KeysetStore interfaces
- pkg/bunker/acl_adapter.go: ORLY ACL integration
- app/handle-cashu.go: HTTP endpoints
- docs/NIP-XX-CASHU-ACCESS-TOKENS.md: Full specification
