ChainLocker

ChainLocker is Piprate’s commercial, enterprise-ready extension of MetaLocker - built for organisations that need secure data exchange at scale, with production integrations, deployment flexibility, and operational controls. It provides a core data sharing service with an API for data storage, sharing, and retrieval, designed to support trusted collaboration across parties without giving up custody of sensitive data.

MetaLocker gives you the open framework. ChainLocker delivers the enterprise platform.

Built for corporate reality: trust, governance, and scale

When data must move between business units, partners, brokers, carriers, vendors, or regulators, traditional sharing creates risk: uncontrolled copies, unclear permissions, and poor auditability.

ChainLocker is designed to replace those brittle workflows with an architecture where:

Custody stays with the owner - clients maintain control over where data is stored and never have to surrender it to participate.
Sharing is accountable - terms and conditions of sharing can be immutably recorded on a ledger, and access can be revoked.
Provenance is continuous - updates, augmentation, and changes are folded into an immutable provenance chain for future reuse and defensibility.

What ChainLocker enables

Secure corporate data storage (Vaults)

ChainLocker Vaults act as the main storage layer for stored/shared data, supporting on-prem or cloud patterns. Data is protected with AES-256 end-to-end encryption, and only participants in the transaction can decrypt it. Vaults can be implemented using file systems, cloud storage, IPFS, or web services that serve data.

Instant, bidirectional data exchange

Data artefacts are made available through lockers - permanent, bidirectional communication channels between one or more participants - enabling fast, controlled sharing while keeping visibility and verification limited to transaction participants.

Evidence-ready audit trails

Need to prove a transaction occurred? Piprate’s platform can provide cryptographic evidence to third parties such as regulators or legal counsel.

Enterprise integrations and deployment flexibility

ChainLocker is designed for enterprise environments where integration and infrastructure choices matter:

Hyperledger Fabric connector (enterprise-grade permissioned ledger integration)
AWS integration, including cloud-native deployment patterns
Backend-agnostic architecture - designed to run on multiple backends, including Hyperledger Fabric, Flow, and even AWS S3 storage or a relational database depending on the deployment model.
Integration-friendly tooling - flexible APIs and command-line tools built with enterprise deployment in mind.

How it works in practice

Your systems connect securely via cryptographically secure APIs to a ChainLocker node.
Data is stored encrypted in vaults you control; metadata and transaction state are handled through the platform’s modular architecture.
Sharing events are recorded for transparency and accountability, with the ability to revoke access when needed.
Provenance accumulates over time, making downstream analysis, compliance, and reuse dramatically easier.

Is ChainLocker for you?

ChainLocker is a fit for organisations that need to exchange data across boundaries with confidence - especially where security, privacy, auditability, and long-term data value are non-negotiable. Piprate’s architecture principles emphasise minimising access, reducing data movement and copies, and keeping custody with primary owners/beneficiaries.
