1. Start Interval:
"Focus Time" (25min) ──► [Interval ID: abc123]
2. Encrypt Data:
"secret" + abc123 ──► [Timelock ID: xyz789]
3. Attempt Decrypt:
- Before interval ends: "Not yet decryptable"
- After interval ends: "secret"Security Features

└─────────────┘ └─────────────┘Architecture
The server consists of four main components:
1. TimeFuzz: Provides timing attack protection through:
- Random duration fuzzing
- Constant-time comparisons
- Jittered timestamps
- Random operation delays
2. TimeKeeper: Manages intervals with:
- Creation/pause/resume operations
- Progress tracking
- Automatic cleanup
- Fuzzing integration
3. TimeLock: Handles encryption with:
- drand network integration
- Interval-based decryption
- Automatic cleanup
- Secure random number generation
4. TimeVault: Provides persistent storage and analytics:
- DuckDB WASM-based storage
- Historical tracking of encrypted data
- Analytics and statistics
- Query capabilities with filtering
TimeVault Commands
Query historical data and statistics about encrypted timevaults:
# List vault history with filtering
list_vault_history --interval_id=abc123 --decrypted_only=true --limit=10
# Get vault statistics
get_vault_stats
Example output:
Total vaults: 150
Decrypted vaults: 75
Average decryption time: 45 secondsStorage Schema
The TimeVault uses DuckDB WASM for persistent storage with the following schema:
CREATE TABLE timevaults (
id VARCHAR PRIMARY KEY,
encrypted_data TEXT NOT NULL,
round_number BIGINT NOT NULL,
created_at TIMESTAMP NOT NULL,
decrypted_at TIMESTAMP,
interval_id VARCHAR NOT NULL,
metadata JSON
);
-- Indexes for efficient querying
CREATE INDEX idx_interval_id ON timevaults(interval_id);
CREATE INDEX idx_created_at ON timevaults(created_at);Contributing
