What is Lattice DA?
Lattice DA is a standalone data availability (DA) layer designed to store large and sensitive datasets directly on-chain with verifiable integrity and long-term historical protection.
It is built for scenarios where data correctness, availability, and auditability matter more than execution, including:
Medical or compliance data
GPS and telemetry logs
Documents and records
Bridge, rollup, and cross-chain data
Analytics and audit trails
The problem it solves
Traditional blockchains are not designed for large-scale data storage:
High costs per byte
Limited throughput
Weak guarantees around long-term historical integrity
Off-chain storage systems, on the other hand, lack cryptographic guarantees and require complex trust assumptions.
Teams are forced to choose between cost, security, or availability — rarely all three.
How Lattice DA works
Lattice DA is purpose-built for data:
Hybrid DAG-based data ordering for high throughput
Merkle root verification for cryptographic integrity
PQ keys on genesis and nodes to protect historical data from future threats
Designed for low-cost, large-volume on-chain data storage
Every data batch stored in Lattice DA is:
Verifiable
Auditable
Permanently available
Cryptographically linked to chain history
This makes Lattice DA suitable as a foundational data layer for Layer 1s, Layer 2s, enterprises, or regulated environments.
Why it matters
Lattice DA enables teams to:
Store sensitive or high-volume data on-chain
Prove data authenticity at any point in time
Reduce infrastructure complexity and cost
Prepare data systems for long-term historical security
It is not an execution layer.
It does one thing extremely well: secure, scalable, verifiable data availability.
