Piprate
Piprate is a Dublin-based company building trusted infrastructure for private data exchange and shared intelligence in an AI-driven world. Its core products, MetaLocker and Sequel (with ChainLocker also offered), enable organisations and individuals to share sensitive data selectively while retaining ownership, provenance, and auditability. Piprate's origins are in solving data-sharing challenges for regulated industries such as insurance, and it now serves enterprise, ecosystem, and emerging personal data use cases.

Description
ChainLocker is Piprate's enterprise data sharing platform, built as a commercial extension of the open-source MetaLocker framework. It replaces brittle, uncontrolled data-sharing workflows with an architecture where custody stays with the data owner, sharing terms are immutably recorded, and provenance accumulates continuously for future reuse and defensibility. Core features include ChainLocker Vaults for AES-256 end-to-end encrypted storage (on-prem, cloud, IPFS, or web services), 'lockers' for permanent bidirectional data exchange channels between participants, and cryptographic audit trails that can serve as evidence for regulators or legal counsel. The platform is backend-agnostic, supporting integrations such as Hyperledger Fabric, Flow, AWS (including AWS S3), and relational databases, with flexible APIs and command-line tools designed for enterprise deployment. ChainLocker targets organisations - such as those in insurance and other regulated industries - that need to exchange data across organisational boundaries with strong requirements around security, privacy, auditability, and long-term data value.Category: Decentralized File Storage
Sequel

Description
Sequel is Piprate's next-generation social platform designed around user ownership and privacy rather than platform-controlled data. Built on top of MetaLocker's private, permanent, bi-directional communication channels ("lockers"), Sequel stores users' posts, photos, and replies in their own personal data wallets instead of a centralized database, giving users control over what they share and with whom, with no user tracking. The platform supports seamless multiple identities for different contexts (professional, personal, creative, or anonymous) and is Fediverse-ready via ActivityPub support, enabling interoperability with other decentralized social networks. Sequel's server software can be deployed as independent instances called "spaces" for communities, companies, or niche groups, which can run independently or synchronize through a shared distributed ledger for network-wide, auditable trust without a central gatekeeper. Sequel Nova, one of the Sequel Spaces, is live as a web experience, and the platform targets communities wanting to run their own platform, creators seeking ownership and provenance over distribution, and anyone wanting a portable, sovereign, AI-resistant digital life.Category: Social Platform
MetaLocker
Project Links
Description
MetaLocker provides an operational layer for publishing and exchanging data while keeping control with the source, offering secure data custody (data stored under the owner's control with strong encryption), selective sharing (granting access to specific parties and datasets rather than broad permissions), provenance and auditability (recording exchanges to prove what was shared, when, and under what terms), and revocable access (ability to update or withdraw permissions over time). It is designed as 'trust-by-design' infrastructure so that AI models and agents can work with high-quality, traceable data without organizations losing purpose limitation, consent, or accountability. MetaLocker underpins Piprate's broader product suite, including ChainLocker, a commercial enterprise-ready product built on MetaLocker's features, and is aimed at industries such as insurance, healthcare, and research that require secure, audit-ready data collaboration.Category: Data
