What is Pilier?
Pilier is an open-source Polkadot SDK blockchain designed to provide verifiable, sovereign infrastructure for real-world asset tracking and compliance automation.
Built with EU sovereignty in mind, Pilier enables organizations to create immutable audit trails, store verifiable documents, and automate compliance workflows—all while maintaining full control over their data and infrastructure.
Why Pilier Exists
Modern supply chains and regulatory frameworks demand verifiable proof of product lifecycle events, document authenticity, and compliance with evolving regulations like ESPR and CSRD.
Traditional systems are:
- ❌ Centralized and opaque
- ❌ Expensive to audit
- ❌ Prone to data manipulation
- ❌ Difficult to integrate across organizations
Pilier solves these problems by providing a neutral, open blockchain layer that anyone can use, verify, and build upon.
What Pilier Provides
1. Verifiable Document Storage
Store cryptographic hashes of documents on-chain with timestamps and metadata. Anyone can verify authenticity by:
- Downloading the document from its URL
- Calculating its hash
- Comparing with the on-chain record
Use cases:
- Certificates of origin
- Compliance reports
- Invoices and shipping documents
- Intellectual property timestamping
2. Digital Product Passports (DPP)
Structured, compliance-ready product passports that track lifecycle events from manufacturing to end-of-life.
Standards supported:
- ESPR (EU Ecodesign for Sustainable Products Regulation)
- CSRD (Corporate Sustainability Reporting Directive)
- Battery Passport (EU Battery Regulation)
- GS1 Digital Link / ISO 15459
3. Autonomous Agents
Programmable workflows that execute automatically based on triggers:
- IoT sensor readings
- Time-based events
- External API responses
- On-chain state changes
Example workflow:
Trigger: Temperature sensor reads > 25°C
Actions:
1. Update DPP with compliance flag
2. Send webhook to logistics provider
3. Record event on-chain
How Pilier Works
Business Logic Flow
Here's a typical product lifecycle using Pilier blockchain:
Key points:
- Backend API abstracts blockchain complexity - manufacturers don't need wallets or understand extrinsics
- Files stored off-chain (S3/IPFS) - only hashes go on-chain to keep costs low
- Anyone can verify - customers query blockchain directly via RPC (no API needed)
- Immutable audit trail - all state changes recorded with timestamps
Technical Architecture
Pilier runs on Polkadot SDK with Proof-of-Authority consensus:
Components:
- Validators: 3 authority nodes producing blocks via Aura consensus
- Finality: GRANDPA ensures irreversibility within ~12 seconds
- Pallets: Modular runtime components (core Polkadot SDK + custom Pilier logic)
- RPC: Public endpoint for querying state and submitting transactions
For detailed architecture, see Architecture Deep Dive. Pilier is built on [Polkadot SDK](https://Polkadot SDK.io/), the same framework used by Polkadot, giving it:
- ✅ Battle-tested consensus (Aura + GRANDPA)
- ✅ Forkless runtime upgrades
- ✅ Modular architecture (pallets)
- ✅ Cross-chain compatibility (future)

Key Features
EU Sovereignty
- GDPR-compliant by design
- Optional SecNumCloud hosting
- FranceConnect / eIDAS integration ready
- Open public verifier
Developer-Friendly
- Standard Polkadot SDK RPC
- Well-documented pallets
- Local devnet setup via Docker
- Comprehensive test suite
Extensible
While initially focused on DPP compliance, Pilier's modular architecture supports future use cases:
- Intellectual property timestamping
- Notarization services
- DAO governance
- Custom compliance frameworks
Reputation-Based Trust
Pilier introduces PIL Trust (tPIL), a reputation system that:
- Rewards long-term commitment with governance rights
- Enables secure P2P interactions through trust bonds
- Provides cross-platform trust scores for ecosystem builders
Unlike traditional blockchain voting (1 token = 1 vote), tPIL requires time commitment, ensuring governance by those with long-term alignment.
Who is Pilier For?
Validators
Run infrastructure, secure the network, and participate in governance.
Blockchain Developers
Build custom pallets, integrate with existing chains, or fork for specialized use cases.
Enterprise Integrators
Use Pilier's blockchain directly via RPC/REST APIs without relying on third-party SaaS.
Application Builders
Build on top of Pilier (like pilier.org) to create user-facing compliance tools.
→ DPP Services Example (coming soon)
Example: DPP Services
Pilier.org is the first commercial application built on Pilier.net. It provides:
- OAuth-based authentication (no crypto wallets for end users)
- Drag-and-drop document uploads
- Pre-configured DPP templates for common industries
- Backend that handles all blockchain interactions
This is just one example. Anyone can build similar applications using Pilier's open infrastructure.
