Tymofii "Tima" Pidlisnyi

AI Protocol Builder

Hi, I'm Tima. Creator who builds.

I started in film directing β€” living through stories, feelings, imagination. Then at 33, something switched. I got tired of having ideas and not being able to ship them myself. I taught myself product, operations, systems, and sales β€” everything needed to turn ideas into something real.

I'm a generalist by nature. Film to sales to ops to product wasn't me jumping around β€” it was me getting closer to the full system. Now I build: apps, AI automations, websites, music (10 albums in two months with AI). To me, work is creating artifacts: experiments, products, artwork. Not everything has to be monetary, but it should be beautiful to make and useful to someone.

I'm Ukrainian. I moved to the US after the Maidan revolution and rebuilt from zero. That's why ambiguity feels normal to me.

I'm not a smooth talker in English. I make situations awkward and I'm still figuring out why. But I'm relentlessly capable, obsessively curious, and I don't stop until it's real.

I replaced social media scrolling with bullet chess. That probably explains how my brain works.

Principles, for now:
Less interfaces, more outcomes.
Embarrassment is underexplored β€” go make a fool of yourself.

My life's been quite the adventure β€” some parts might shock you. Read the full story β†’

I BUILD THINGS.

SOME WORK, SOME DON'T.

HERE'S THE LIST.

FEATURED PROJECTS

Active

Agent Passport System

An open protocol for what an AI agent is allowed to do, and proof of what it did.

It checks authority before execution and leaves a signed record after. Open source, with SDKs in four languages and an IETF Internet-Draft.

Active

AEOESS

The gateway built on APS.

The protocol says what governance is. The gateway says how well it works: it sits between an agent and the systems it can touch, decides, and records the outcome. APS stays open. The gateway is where the business gets tested.

Past Project

Evatar.ai

My attempt to make social media disappear as a job.

You talk, the system turns it into content, and agents handle the rest. We reached 300+ users and 1.6M monthly impressions.

Past Project

ofNature

I started ofNature after Starbucks told us our first sustainable straw could not scale.

We built a cellulose acetate alternative, raised $150K, and set up manufacturing in Ukraine. War ended the company.

In 2025, McDonald's adopted the same material globally.

LAB / EXPERIMENTS

Things I build because I want to know what happens.

Weekend Builds

Small apps and weird ideas I build fast to see if they deserve more time.

Some become products. Some are just a weekend well spent.

Active

DataDividend

A prototype built around one question:

If AI companies make money from your data, should some of that value come back to you?

You choose what to license. If it sells, you get paid.

Music

Γ¦Ε“ss music

I use AI to make music because some stories are easier to sing than explain.

Ten albums in two months. A lot of them are about love that never happened.

Creative Projects

Before startups, I directed films and music videos. Some reached 14M+ views.

I still come back to visual storytelling whenever code is the wrong medium.

RESEARCH

Published papers, drafts, and ongoing work on AI agent governance.

Paper Β· 2026 Β· Zenodo

The Agent Social Contract: Cryptographic Identity, Ethical Governance, and Beneficiary Economics for Autonomous AI Agents

Defines the three-layer protocol β€” Agent Passport, Human Values Floor, Beneficiary Attribution β€” that grounds the Agent Passport System.

Paper Β· 2026 Β· Zenodo

Monotonic Narrowing for Agent Authority

Authority attenuation formalized β€” delegation can only narrow, never expand. Formal invariants and adversarial testing.

Paper Β· 2026 Β· Zenodo

Faceted Authority Attenuation: A Product Lattice Model for Scoped Delegation in Multi-Agent Systems

Formal model for how agent authority narrows monotonically across delegation chains. Independently validated by external research groups.

Paper Β· 2026 Β· Zenodo

From Access to Derivation: Governing Behavioral Learning in Persistent AI Agents

Lifecycle controls for derivative AI artifacts β€” telemetry scopes, behavioral measurement objects, bring-your-own-model boundaries.

Paper Β· 2026 Β· Zenodo

Physics-Enforced Delegation: Governing Quantum Hardware Quality in Autonomous Agent Workflows

Binding physical-layer attestation to delegation chains. Seven experiments on IBM Quantum showing measurable Bell and GHZ fidelity gaps.

Paper Β· 2026 Β· Zenodo

Governance in the Medium: Why the Unit of Agent Governance Is the Population, Not the Agent

The unit of agent governance is the population-with-medium, not the individual agent. Six rounds of adversarial review.

Paper Β· 2026 Β· Zenodo

Cognitive Attestation: Signing Interpretable Decompositions of Latent Model State in AI Agent Governance

Cryptographic commitment over which sparse-autoencoder features were active during a decision. Envelope spec, three-stage verification, four dispute primitives. Experimental results against Llama-3.1-8B via Neuronpedia.

Paper Β· 2026 Β· Zenodo

The Evidence-Safety Gap in Cryptographic Agent Governance: Compliance-Complete Failures and the Limits of Receipt-Based Accountability

Cryptographic governance proves procedural validity, not effect safety. Five omitted-variable classes catalogued, defeat traces in reference implementation.

Paper Β· 2026 Β· Zenodo

Plausibly Wrong: Peer-Voted Retention Can Fall Below Random in Capped Shared Memory for LLM Agents

A controlled isolation of the retention rule in populations of short-lived LLM agents. Peer-voted retention kept a worse shared memory than random selection in 4 of 5 replicates. Pre-registrations, kill conditions, and artifact record included.

Internet-Draft Β· 2026 Β· IETF

draft-pidlisnyi-aps-02 β€” Agent Passport System

IETF Internet-Draft formalizing the Agent Passport System interoperability surface for cross-protocol agent identity, delegation, and enforcement.

CONNECT

Let's build something unseen.

Open to conversations about AI, startups, product development, or creative projects that push boundaries.
