BLACK RABBITS LAB
Development of Intelligent Systems
We design and deploy intelligent systems built on AI models, equipping them with domain knowledge, specialized tools, and the ability to act. Each system is developed around the logic of its field—from medicine and ecology to logistics, energy, financial markets, and decentralized finance. Our systems are designed to protect your data and privacy. We build products that remain reliable, scalable, and sustainable in an unpredictable and unstable world.
Robust Systems
We create systems that preserve their purpose even when the conditions around them move beyond the range for which they were designed. By enforcing minimal dependencies and adaptable design, our systems dynamically adjust to changing environments.
Transparent Privacy
Transparency should apply to the system—not to the person. We design products whose logic, data flows, and security boundaries can be understood and audited, while personal information remains private and under the user’s control. Medical records, financial data, correspondence, and everyday personal context are isolated and protected, whether stored locally or processed within a secure environment.
UNCERTAIN WORLD: BLACK SWANS, DRAGON-KINGS & BLACK RABBITS
“In an environment where shocks can change direction so quickly, it would not be wise to anchor our decisions too firmly…”
“What we call here a Black Swan (and capitalize it) is an event with the following three attributes. Rarity, extreme impact, and retrospective—though not prospective—predictability.”
“Dragon-kings are defined as extreme events that do not belong to the same population as the other events, in a precise quantitative and mechanistic sense.”
“By analogy with this term, we have named Black Rabbits events that exhibit all the external characteristics of a Black Swan but are entirely determined by the state of the system itself.”
The first chart shows the dynamics of a simple discrete dynamical system in which each value is equal to the sum of the two preceding values. The construction follows the famous Fibonacci sequence, but instead of starting with two ones, we choose the initial values 1 and −0.618033.
At first, the system stabilizes and approaches zero. Then it enters a stable regime. Suddenly, it begins to exhibit explosive exponential growth.
The second chart shows the actual exchange rate of Zcash against the euro in August 2026.
The first example shows that even the simplest linear systems in a phase space of sufficiently high dimensionality—in this case, two—can exhibit unpredictable and unstable behavior. Figuratively speaking, the system was pregnant with a crisis from the very beginning.
The intelligent systems developed by our laboratory can identify and classify points that signal an approaching crisis. Because these systems are based on mathematical models, they can be applied not only to finance and financial markets, but also to medicine, ecology, energy, and many other domains.
In engineered systems, our algorithms can provide robust, non-invasive stabilization; in biological systems, they can help maintain or restore homeostasis; and in ecological systems, they can support ecosystem stability and resilience.
ZERO-KNOWLEDGE TECHNOLOGIES AND CRYPTOCURRENCY
Cryptocurrency tools and consulting, combined with applied Zero-Knowledge technologies for privacy, compliance, and secure digital systems.
PRODUCTS & TOOLS
Crypto Tracer
An interactive investigation platform designed for real-time on-chain analysis, transaction graph tracking, and cryptographic asset flow visualization across decentralized networks.
For a quick visualization, use the sample address below—or any other address you want to explore. Copy it, open Crypto Tracer, and paste it into the address field.
Crypto Tax Estimator — Portugal
A calculator for estimating Portuguese tax liability on crypto trading and investment gains. Client-side only: your data never leaves your browser. Informational output — not tax advice.
CONSULTING
ZK Protocol Design & Audit
We analyze, design, and verify zero-knowledge proof systems. Using frameworks like Circom, Noir, and Halo2, our mathematicians ensure your circuits are mathematically secure, optimized for speed, and free of vulnerabilities.
Enterprise Privacy & Scaling
We build scalable zk-Rollup structures and private value-transfer layers. This allows businesses to process bulk transactions off-chain and verify them on-chain with minimal gas fees and complete confidentiality.
Compliance & Identity (GDPR/eIDAS)
We construct privacy-preserving identity solutions that comply with European GDPR and eIDAS 2.0 frameworks. Prove user eligibility, compliance status, or solvency without exposing sensitive customer data.
Crypto Taxation in Portugal
Orientation in the Portuguese tax treatment of crypto trading and investment. Informational consulting — not a substitute for a licensed tax advisor.

PRODUCTS
OlgaGo
An executive mobile intelligent system designed to organize both work and everyday life. OlgaGo prepares daily briefings, analyzes correspondence, drafts and sends messages, manages schedules, assists with travel booking, and coordinates personal and professional logistics.
Dr. Standalone
A private desktop health companion that works with you as a personal home doctor. It records daily health measurements, maintains your medical history, and analyzes the photographs and documents you choose to provide. Your personal medical data remains on your own computer, while a secure server-side intelligence layer connects the application to advanced AI models and extensive medical knowledge bases. Dr. Standalone can support preliminary health assessment, identify emerging patterns, and provide personalized recommendations related to medical consultation, medication, physical activity, and everyday health management.
Sophia
An intelligent academic assistant that helps students navigate complex educational workflows. Sophia transforms unstructured assignments into clear plans, milestones, deadlines, and calendar events. It supports the full research and writing process—from organizing coursework and preparing essays to structuring, developing, and revising advanced academic work, including doctoral research.
