Chain Engine

Nowadays companies don't just pay for data storage. They pay a massive "Mutation Tax". Complex backup licenses. Enormous cloud clusters burned on heavy indexing. Constant resource-hungry updates to keep the state accurate. And entire armies of auditors are hired just to prove that the historical data hasn't been tampered with.

Chain Engine eliminates this complexity by embedding cryptographically secured immutability directly into the application data-layer. Providing the application with:

Event Sourcing as a Fortress:
The application state is derived from the immutable ledger and maintained in in-memory replicas. Even if an insider or hacker manages to touch the raw disk, it will be impossible to activate the unauthorized state changes, because the restart required for activation will not pass the rigorous integrity checks during the restart.

Auditability & Compliance by Design
Every event is encrypted, cryptographically sealed, and time-stamped. This results in a perfectly traceable, tamper-proof audit trail. Auditors and compliance officers gain immediate insight into what really happened, without expensive external systems or complex reconciliation processes.

Blazing Performance
Capable of pushing exceptional volumes of end-to-end task transactions per second out-of-the-box on standard, cost-effective hardware. Read requests run at pure RAM speed.

Fast Development
All business logic resides in a library outside the engine. Organizations can focus on the domain rules from day one.

Chain Engine brings the power of an immutable ledger into everyday business applications. It features a modular architecture compiled into a single binary, driven by three core components that make Chain Engine unique. Complemented with a shared type system that ensures the application speaks the same language from start to finish.

Compliance by design is at the core of Chain Engine. Every event is cryptographically secured and stored in an append-only ledger, with full historical traceability.

The engine maintains a human-readable audit.log that is encrypted at rest and hash-chained. The log supports periodic rotation for easy archiving and is automatically recovered on application restart.

To make audits easy and portable, Chain Engine ships with two standalone auditor binaries that generate Merkle inclusion and integrity proofs for any event in the ledger.

Auditors can verify events independently using the generated JSON proofs, without needing access to the live system.

Performance is highly dependent on business logic complexity. A workload involving heavy computations will exhibit different resource characteristics than lightweight state updates. While Chain Engine delivers exceptional throughput out of the box, we recommend to always benchmark under your specific transaction profiles to determine optimal scaling thresholds and monitoring baselines.

Chain Engine is designed to integrate smoothly into existing enterprise IT landscapes without requiring a rip-and-replace approach.

Thanks to a clean, trait-based extension architecture, the engine exposes well-defined extension points for key infrastructure concerns. Organisations can plug in their own implementations for Identity & RBAC, document storage, secrets management, logging, cryptographic providers, and more – while keeping the core engine untouched.

This makes it possible to reuse existing investments in IdP systems, observability stacks, and storage solutions. Runtime configuration further allows fine-tuning of slot timing, snapshot policies, audit log rotation, data compression, memory limits and queue management et al. – without recompiling the application.

Chain Engine is designed with data privacy principles at its core, particularly when handling personally identifiable information (PII) in enterprise applications.

It goes without saying that PII should only be stored on the ledger when operationally necessary. Multiple layers of safeguards are in place to support compliance with GDPR, CCPA and ISO 27001.

The engine comes with enterprise-grade safeguards that are either built-in (out-of-the-box) or prepared via extension-points:

Right to Erasure and Storage Limitation

Modern Agentic AI systems are only as good as the data they operate on. They require clean, consistent, trustworthy, and fully auditable data to make reliable decisions and take autonomous actions.

Traditional databases often fail here. Messy, mutable data leads to hallucinations, incorrect decisions, and costly mistakes. Organizations end up spending more time fixing data issues than actually leveraging AI – turning what should be a strategic advantage into an expensive disappointment.

Chain Engine fundamentally changes this paradigm. The immutable and event-driven data is clean and consistent by definition, creating an ideal foundation for agentic AI. The output of AI agents can therefore be trusted with confidence. This allows your teams to focus entirely on innovation and value creation, ensuring that your investment in agentic AI truly delivers results.

The Chain Engine is built with future-proof cryptography in mind. It currently uses industry-standard primitives (cryptographic hashing and authenticated encryption at rest using AEAD algorithms), but all cryptographic operations are implemented through clean, configurable provider interfaces.

This abstraction layer allows organisations to seamlessly switch to post-quantum cryptographic algorithms as soon as standards mature – without code changes or architectural rework.

By preparing for post-quantum cryptography today, Chain Engine helps protect sensitive enterprise data against emerging quantum computing threats while maintaining full compatibility with current standards.
