Pyrsia

Pyrsia is an open-source decentralized package and container delivery network (software supply chain security and artifact distribution) designed to provide verifiable, tamper-evident software artifacts for build and deployment pipelines.

  • Decentralized package and container distribution network (artifact delivery)
  • Uses distributed ledger and peer-to-peer technologies to record and share artifact metadata (software supply chain security)
  • Provides cryptographic verification of build provenance and artifact integrity (integrity and provenance assurance)
  • Integrates with existing build and Continuous Integration and Continuous Deployment (CI/CD) systems to publish and consume artifacts (DevOps and CI/CD tooling)
  • Aims to reduce dependency on single-vendor artifact repositories and centralized registries (resilience and vendor-neutral distribution)

More About Pyrsia

Pyrsia is an open-source project under the Continuous Delivery Foundation (governance and community) that focuses on securing the software supply chain through a decentralized network for distributing software packages and container images. The project addresses risks associated with centralized artifact repositories and opaque build processes by providing an alternative distribution mechanism with verifiable provenance and integrity for artifacts used in enterprise build and deployment pipelines.

At its core, Pyrsia implements a decentralized package and container delivery network (artifact distribution) built on peer-to-peer networking (distributed systems) and a distributed ledger (blockchain-style record-keeping) to track metadata about built artifacts. Nodes in the Pyrsia network participate in building, storing, and serving artifacts, while metadata about builds, signatures, and provenance is recorded in an append-only ledger. This design helps enterprises verify where an artifact came from, how it was built, and which party attested to its contents before using it in production pipelines.

Pyrsia integrates with existing CI/CD and build systems (DevOps tooling) so that teams can publish artifacts to the Pyrsia network as part of their standard pipelines. The project exposes interfaces compatible with common artifact workflows (artifact management), enabling build tools and deployment systems to pull artifacts from Pyrsia similarly to how they interact with conventional registries or package repositories. Enterprises can run their own Pyrsia nodes to participate in the network, cache artifacts locally, and maintain control over which artifacts and attestations they trust.

The project applies cryptographic signatures and verification (security and cryptography) to ensure that artifacts retrieved from the network match the content that was originally built and attested. Provenance information and metadata stored in the distributed ledger help organizations validate that artifacts were built from expected sources and processes, supporting Supply Chain Risk Management (SCRM) and compliance requirements. The decentralized model aims to limit single points of failure and reduce exposure to compromised central registries.

Within an enterprise environment, Pyrsia can be positioned as part of a broader software supply chain security stack (security and compliance) alongside existing CI/CD, artifact management, and policy enforcement tools. The project is developed under the Continuous Delivery Foundation umbrella (open-source foundation), aligning it with other projects focused on Continuous Integration (CI), delivery, and Release Automation (RA). For technical taxonomies, Pyrsia fits into categories such as decentralized artifact distribution networks, software supply chain security platforms, and verifiable package and container registries used to support secure continuous delivery practices.
