SQL on a post-quantum blockchain
The web3 backend for SQL-based applications. 99% of websites that matter run on SQL. Seal gives them decentralization, privacy, and post-quantum security — without changing how they work.
# Deploy your app seal app deploy --name myapp.seal --schema schema.sql # Query from anywhere seal sql "SELECT * FROM myapp.users" --node http://node:8545 # Your schema.sql is just PostgreSQL CREATE TABLE users ( id BIGINT PRIMARY KEY, email TEXT NOT NULL, balance BIGINT DEFAULT 0 );
Post-Quantum Crypto
ML-DSA-65, ML-KEM-768, SHA3-256. NIST-standardized. Future-proof against quantum computers. No classical crypto on-chain.
PostgreSQL-Compatible SQL
CREATE TABLE, INSERT, SELECT, JOIN, WHERE. Row-level security with CREATE POLICY. Your existing SQL skills work here.
Three Privacy Levels
Public tables, RLS-protected tables, and private tables encrypted at rest. MPC aggregates and ZK proofs for private data access.
Namespace Sharding
Each app gets its own shard. Nodes choose which namespaces to serve. Scales horizontally as the network grows.
Verifiable Queries
Every query result is backed by a Merkle proof against the state root. ZK proofs via RISC Zero / SP1 for privacy-preserving verification.
On-Chain DEX
Built-in limit order book. Create custom tokens, trading pairs, and place orders. All signed with ML-DSA-65.
What Seal adds to SQL websites
| Today | With Seal |
|---|---|
| You manage your own database servers | The network manages replication for you |
| You build auth from scratch | Cryptographic identity built-in (ML-DSA) |
| You trust your hosting provider with your data | Data encrypted at rest, verified by math |
| You hope your backups work | Replication across multiple nodes by default |
| Users trust you not to tamper with data | Merkle proofs and ZK proofs verify everything |
| Vulnerable to quantum computers (eventually) | Post-quantum from day one (ML-DSA, ML-KEM, SHA3) |
| Locked to a cloud vendor | Decentralized, no single point of failure |
