75% of data today is created at the edge.
Why send it to the cloud when we can leverage it where it already is?
Edge-first data
must be
Edge Native
On-device computation reacts to data as it's produced or received, without waiting on the cloud. Reduce latency, slash bandwidth costs, and make decisions in real-time, even if connectivity is unreliable.
Real-Time Data Hooks
Event-driven listeners on the device that trigger processing pipelines the moment new data is created or received, no cloud round-trip needed.
Incremental State Management
Local state stores that diff incoming changes incrementally, keeping memory and CPU footprints minimal while preparing data for efficient sync.
Offline-First Processing
Background workflows that queue, process, and checkpoint data mutations during disconnection, then seamlessly reconcile when connectivity returns.
Proximity-Optimized Analytics
Edge-tuned operators (aggregations, filters, transforms) that reduce data before any sync, slashing bandwidth and speeding up insights.
Peer-to-Peer
Data moves through direct or relay-based zero-trust peer nodes, bypassing centralized servers. This eliminates single points of failure and high-visibility attack targets.
Network Topology
Fully decentralized network using powerful peer-to-peer frameworks and node identities derived from asymmetric keypairs
Data Structure
Single evolving Merkle DAG per document with static Document IDs, maintaining consistency across mutations
State Propagation

Automated packaging tools that detect the target environment and produce optimized bundles with minimal developer overhead.
Secure
Data you can't protect, you can't trust. Encrypt end-to-end, both in transit and at rest. Protect keys so only authorized devices and parties can access them.
Threshold Secret Rings
Collaborative Key Generation (CKG) produces aggregated public keys and requires a quorum of individual keyshares to decrypt or sign.
Proxy Re-Encryption Streams
Re-encryption keys enable ciphertext migration between public keys without ever exposing plaintext.
Zero-Knowledge KMS
User-friendly key management combining zero-knowledge proofs with public-key operations, offering both simplicity for end users and full control for advanced stakeholders.
Automatic End-to-End Encryption
Seamless on-device encryption/decryption pipelines for data at rest and in transit, with hardware-backed isolation where available.
Private
Data-level permissions travel with the data as it syncs, ensuring it's only accessed and processed as authorized.
Policy-Driven Access Control
A decentralized policy engine built on DIDs to enforce permissions consistently across all devices and data flows.
Signed Permission Receipts
Each record carries a cryptographically signed access receipt that any node can verify before allowing operations.
Multi-Model Authorization Support
Built-in frameworks for RBAC, ABAC, ReBAC, and DAC enable granular, context-aware permissioning.
Partitioned Policy Enforcement
Policies are sharded and processed in parallel across devices, ensuring real-time, scalable enforcement even when disconnected.
Embedded Compliance Controls
Governance rules for consent, data residency, and minimization are baked into the data layer, guaranteeing regulatory adherence at the edge.
Verifiable
Each record contains cryptographic proof (signatures, hashes, Merkle trees) for end-to-end verifiability. Power multi-device collaboration over a shared source of truth, while supporting compliance and forensic audits.
Content-Addressed Event Chains
Every mutation is stored as a Merkle DAG node referencing its predecessor, ensuring tamper-evident, content-addressable history.
Causal Merkle Clocks
Directed acyclic graphs enforce forward-only event ordering, eliminating circular dependencies and preserving causal consistency.
Embedded δ-State CRDTs
State-based and operation-based CRDT payloads live inside each Merkle node, combining convergent and commutative replication semantics.
Recursive ZK Verification
Recursive zero-knowledge proofs enable high-performance snapshotting and integrity checks without traversing long DAGs.
Decentralized Identity Management
Self-sovereign identities via the DID protocol, enabling secure, cloud-independent authentication for users and services.
Tamper-Evident Auditing
Append-only provenance logs with cryptographic proofs, providing full traceability, accountability, and regulatory compliance.

Why Developers Should Build On Source
Dwight Merriman
Co-Founder of MongoDB
"Modernization of the data layer in our systems is overdue. In a semi-centralized data center scenario, there are new databases, with new data models (often document-oriented), that work better for the use cases of today, which involve new data shapes, evolving schemas, polymorphism, and iterative development."
