# About

**TransferChain S4** (Secure Simple Storage Service) is a Dockerized, S3-compatible secure object storage backend built on TransferChain’s patented privacy and security protocol. It ensures **end-to-end encryption**, **client-side data splitting**, and **blockchain-based audit logging** — providing unmatched confidentiality and compliance for enterprises and developers alike.

TransferChain S4 is storage-agnostic and integrates seamlessly with your existing infrastructure while enabling full control over **data residency**, **encryption keys**, and **transfer authorization**.

This documentation helps open-source developers get started with S4, explaining how to install, initialize, store and retrieve data, and manage transfer and blockchain components securely.
