While NextGraph is evolving

While NextGraph is Evolving...

We can follow this outline with detailed technical explanations, including what, why, and how, to begin exploring how to move forward...

1. Leverage NextGraph’s Core Protocol and Local-First Repositories

Key Action 1: Set up local repositories for structured data (RDF/JSON-LD) and rich-text documents

What: NextGraph uses Conflict-Free Replicated Data Types (CRDTs) to manage data synchronization across peers. Local repositories act as decentralized databases that persist data offline and merge changes automatically.
Why: CRDTs ensure eventual consistency without centralized coordination, critical for P2P apps where users may edit data offline. Structured RDF/JSON-LD enables semantic interoperability, while rich-text CRDTs support collaborative editing.
How:
- Structure data using RDF triples (subject-predicate-object) or JSON-LD (linked data with @context). For example:
```
{
  "@context": "https://schema.org",
  "@id": "user:123",
  "name": "Alice",
  "owns": {"@id": "document:456"}
}
```
- Use SPARQL to query semantic data (e.g., SELECT ?doc WHERE { user:123 owns ?doc }).
- For rich-text, use operational transforms (OT) or CRDT-based editors like Yjs to track changes.

Key Action 2: Implement CRDT operations for conflict resolution

What: CRDTs resolve merge conflicts by design, ensuring all peers eventually converge to the same state.
Why: Traditional databases require manual conflict handling, but CRDTs automate this, reducing developer overhead in P2P networks.
How:
- Use automerge-style CRDTs for JSON data or Yjs for text.
- Define merge strategies for custom data types (e.g., last-write-wins for timestamps).
- Test edge cases (e.g., concurrent deletions/updates) using NextGraph’s CLI to simulate peer divergence.

Key Action 3: Encrypt data at rest in local storage

What: NextGraph encrypts local repositories using AES-256-GCM, with keys derived from a user-provided secret.
Why: Prevents unauthorized access if a device is compromised.
How:
- Data is encrypted before being written to ~/.local/share/org.nextgraph.app (Linux) or platform-specific secure storage.
- Use libsodium for key derivation (Argon2id) and encryption.
- Store recovery kits (encrypted backups of keys) in case of device loss.

2. Utilize Background Services for Encryption and Persistence

Key Action 1: Integrate background services for automated persistence

What: NextGraph runs a daemon/service (e.g., nextgraphd) to manage storage, encryption, and network sync in the background.
Why: Offloads resource-intensive tasks (e.g., CRDT merging) from the app’s main thread, ensuring smooth UX.
How:
- Use gRPC or REST APIs to communicate with the background service. Example API call to persist data:
```
curl -X POST http://localhost:8080/repo/update \
  -H "Content-Type: application/json" \
  -d '{"id": "doc1", "ops": [{"type": "insert", "text": "Hello"}]}'
```
- Configure permissions via manifest.xml (Android) or Info.plist (iOS) to allow background sync.

Key Action 2: Enforce PIN-based unlock for encryption keys

What: Keys are stored in platform-specific secure enclaves (e.g., Android Keystore, iOS Secure Enclave) and require a PIN to decrypt after inactivity.
Why: Balances security and usability—PINs are easier to remember than passwords but still protect against casual breaches.
How:
- Use BiometricPrompt (Android) or LAContext (iOS) for PIN/biometric integration.
- Derive encryption keys using a PIN-stretched key via PBKDF2 with 100,000 iterations.

Key Action 3: Avoid cloud backups for mobile data

What: NextGraph replicates data via broker nodes instead of relying on iCloud/Google Drive.
Why: Cloud backups create centralized points of failure and may violate data residency laws.
How:
- Disable Android’s allowBackup and iOS’s com.apple.developer.icloud-container-identifiers in app manifests.
- Use broker nodes (configured in nextgraph.conf) to handle data replication between trusted peers.

3. Adopt the App Protocol and Smart Contracts

Key Action 1: Define capability-based access controls

What: Users grant fine-grained permissions (e.g., read/write/delete) using cryptographically signed tokens.
Why: Prevents unauthorized mutations in a trustless P2P environment.
How:
- Issue UCAN (User Controlled Authorization Network) tokens for delegated access.
- Example token payload:
```
{
  "issuer": "user:123",
  "audience": "app:456",
  "capabilities": ["doc:789:read"],
  "expiry": 1735689600
}
```
- Verify tokens using Ed25519 signatures during CRDT merge operations.

Key Action 2: Implement smart contracts as WASM modules

What: Smart contracts are finite state machines compiled to WebAssembly (WASM) for cross-platform execution.
Why: WASM is sandboxed, fast, and language-agnostic, enabling complex logic (e.g., payment escrow) without trusting peers.
How:
- Write contracts in Rust/C++ using NextGraph’s SDK, then compile to WASM.
- Deploy contracts to the network via nextgraph contract deploy --file=escrow.wasm.
- Use threshold signatures (e.g., FROST) to enforce Byzantine fault-tolerant consensus on state transitions.

4. Start with Available Tools and Track Upcoming Features

Key Action 1: Use the CLI and Headless API for programmatic testing

What: The CLI (nextgraph-cli) and headless API allow scripting interactions with repositories.
Why: Critical for automating tests and debugging data flows during alpha.
How:
- Initialize a repo: nextgraph repo create --type=jsonld --encrypt.
- Simulate peer sync: nextgraph net simulate --peers=5 --ops=100.
- Export data to debug: nextgraph repo export --format=turtle > data.ttl.

Key Action 2: Experiment with JSON-LD and triple editors

What: NextGraph provides GUI tools to visualize RDF triples and edit JSON-LD documents.
Why: Simplifies designing schemas without writing raw SPARQL.
How:
- Launch the triple editor: nextgraph editor --triples.
- Define custom @context files to map JSON keys to RDF predicates.
- Use SHACL shapes to enforce schema constraints during edits.

Key Action 3: Monitor the 2025 roadmap for SDK/IDE releases (no elaboration needed).

Key Considerations

1. Data Formats: Prioritize RDF/SPARQL and JSON-LD

What: RDF enables semantic queries; JSON-LD adds context to JSON data.
Why: Ensures interoperability with future tools and federated querying across apps.
How:
- Use schema.org vocabularies for common entities (e.g., Person, Document).
- Convert CSV/JSON to JSON-LD using framing:
```
{
  "@context": "https://schema.org",
  "@type": "Person",
  "name": "Alice"
}
```

2. Security: End-to-End Encryption and Recovery Kits

What: Libp2p’s NOISE protocol encrypts peer traffic; recovery kits backup keys.
Why: Prevents MITM attacks and data loss.
How:
- Enable libp2p.noise in the network config.
- Generate recovery kits: nextgraph auth generate-recovery --out=kit.txt.
- Use post-compromise recovery to rotate keys if a device is breached.

3. Future-Proofing: Align with Homomorphic Encryption and UPnP

What: Homomorphic encryption (HE) allows querying encrypted data; UPnP automates NAT traversal.
Why: HE preserves privacy in federated queries; UPnP simplifies P2P networking.
How:
- Test HE prototypes using Microsoft SEAL or OpenFHE for WHERE clause filtering.
- Enable UPnP in nextgraph.conf with net.upnp=true to bypass manual port forwarding.
