Why GeoChain?
GeoChain is a professional marketplace built for trusted geospatial commerce. Every listing carries on‑chain provenance and integrity checks; payments settle fast with escrow safeguards; delivery is encrypted end‑to‑end so sellers keep control and buyers get confidence. Designed for researchers, enterprises, and builders.
Built on the XRPL EVM Sidechain
Uniting EVM smart contracts with XRPL performance. GeoChain inherits the XRP Ledger's speed, low-cost transactions, and reliability, while remaining fully compatible with the EVM toolchain and wallets.
High Throughput, Low Fees
Fast finality and minimal costs suitable for frequent data transactions.
EVM Compatibility
Use familiar tooling, libraries, and wallets with Solidity smart contracts.
XRPL-Grade Reliability
Benefit from the XRPL's mature, proven infrastructure and security.
Interoperability
Designed to integrate with XRPL ecosystems and broader Web3 data standards.
Key Advantages
Exclusive Ownership & Encryption
Sellers retain exclusive ownership; the marketplace cannot access your data. Encrypted delivery uses client‑specific content keys (SSE‑C) protected by KMS/Vault, ensuring zero marketplace visibility.
Fast, Low-Cost Settlement
Near-instant payments on XRPL with minimal fees, suitable for high-frequency transactions.
Transparent Provenance
Onchain records for listings, payments, and integrity checks—easy to audit and verify.
Tamper-Proof Integrity
Every dataset can be verified by comparing stored hashes with fresh hashes at purchase time.
Programmable Licensing
Smart-contract workflows for escrow and licensing to support commercial and research use cases.
Fair & Transparent Pricing
Fair, transparent fee model (5% total; Seller 3%, Buyer 2%) — enabling secure escrow and encrypted delivery.
Security & Privacy
Encrypted Delivery (SSE‑C)
Each buyer receives a unique content key. Keys are protected via KMS/Vault with secure local fallback.
Integrity Verification (SHA‑256)
Server‑side hashing validates delivered files against stored references, ensuring tamper‑proof delivery.
Signed URLs & Short TTL
Access links expire quickly and cannot be reused, minimizing unauthorized sharing.
Hardened API & Rate Limits
Helmet, CORS, and rate limiting protect the marketplace from common web threats.
