Deep dive
The full material behind the homepage: the problem, the architecture, security and governance, the notarial pilot, the product concept and the long-term vision.
The Problem
Our record of ourselves has never been so vast, nor so fragile. It lives on hardware that fails, in companies that close, in formats nobody will read in fifty years.
"We are creating more memories than ever before, yet we have no permanent infrastructure to preserve them."
Drives fail, accounts close, formats rot. A lifetime of images can vanish in a single silent corruption.
The services holding our memories today were not designed to outlive us — or even outlive a decade.
Stories scatter across a dozen apps and devices until nobody can assemble the whole life again.
Languages, rituals and archives disappear faster than institutions can digitise them.
Why now
Three curves intersect for the first time: the explosion of personal data, the maturity of AI, and the collapsing cost of cryptographic proof and long-term archival storage.
A family's entire life now sits in accounts, phones and platforms that nobody controls on a hundred-year horizon.
People, places and event recognition, plus natural-language search, are now available at reasonable cost.
Generative content makes provenance and file integrity a precondition for credibility.
The largest intergenerational transfer of assets and archives in history has already begun.
From conviction to capability
For three years, we have mapped, assessed and validated the technologies, partners and architectural choices required to make Bottle on the Sea real. Today, we have a defined execution path — from the first secure vault to century-scale DNA-on-silicon preservation.
This is not a startup with a vision. It is a concrete architecture, born of deep conviction, engineered so that human memory can outlive the systems that hold it.
What three years produced
From conviction to capability.
The Solution
Bottle on the Sea is a single, permanent home for what a person, a family or a civilization chooses to keep. Three technologies hold it together.
Memory, understood.
AI organises memories, recognises people and events, builds living timelines and lets you interact with your own history — asking questions instead of scrolling folders.
Blockchain-backed where useful, invisible where unnecessary.
An immutable record of authenticity, ownership and provenance. Every memory carries verifiable origin and a secure path of digital inheritance — without ever asking a family to think about a ledger.
Memory, for millennia.
Synthetic DNA encodes information at extraordinary density and stability. We already master DNA data storage on silicon plaques — ultra-long-term preservation far beyond any magnetic or solid-state medium, in technology we hold today.
Human control
Conversational access to an archive is powerful and sensitive. These commitments are part of the architecture, not a policy page written afterwards.
The First Vault
Before century-scale preservation, there is a product. This is the scope of the first version we are building.
Photos, videos, letters, documents and voice notes — brought into one encrypted vault instead of a dozen devices.
People, places and events are recognised and assembled into a private, chronological timeline you never had to build.
Ask "the summer we moved to Warsaw" instead of scrolling folders. Natural language across your entire archive.
Name trusted people and define what they can access, and when — from a specific date to a life event.
The first vault is built with proven technologies available today. The DNA-on-silicon storage layer it will adopt is already mastered by our team — it is not futuristic hardware.
How we sequence it
We are deliberate about what exists, what follows and what remains research. Nothing on this page is presented as further along than it is.
Signature experience
A programmed release is a date. A time capsule is an experience. Here, someone prepares a chapter of the future — voices, letters, photographs, context and instructions — composed as something intimate rather than delivered as a file.
Order, pacing and framing are authored by the person who leaves it.
Cryptographically locked until the chosen date, event or verified recipient.
The archive explains who, where and why — so the moment is understood, not only received.
For Julian, when he turns 25
A voice message from his father, photographs from his earliest years, a letter in his handwriting, and a short AI-built timeline explaining the family story behind them.
The Future
Preservation is the foundation, not the destination. The long-term goal is to turn archived memory into something you can enter, question and feel — an experience rather than a folder.
Speak with a curated model of a life — grounded strictly in the archive it was given.
A shared, permissioned vault that grows across generations rather than resetting each one.
Volumetric reconstruction of places, rooms and moments you can walk back into.
Institutions rebuild lost sites and traditions from fragmented archival evidence.
Digital Legacy
You decide what is released, to whom, and when. Digital inheritance becomes a designed act rather than a lost password: your digital estate is transmitted on your terms. The vault waits — patiently, for years or for decades — and then delivers.
Seal a message today; it opens on an eighteenth birthday.
A life story released on an anniversary, a wedding, a centenary.
Pass on digital assets and transfer custody of the vault under verified digital inheritance.
Donate historical archives to museums, universities and foundations.
"Your memories are not only for today. They are a gift to tomorrow."
Digital Legacy Portal
Most people leave behind an unusable digital life: scattered accounts, unreadable files, and instructions nobody ever found. The Legacy Portal turns that into something structured, verifiable and transmissible.
Memories, photographs, letters, voices — the human archive.
Testamentary documents, contracts, succession instructions.
Estate information, financial guidance, digital-asset access procedures.
Messages destined to one named person, and to no one else.
We will never store a recovery phrase in clear text, and we will never hold, in one place, everything needed to move someone's assets. Digital-asset succession is designed as cryptographic secret management, or it is not designed at all.
The Legacy Portal is a Next-horizon module. It is specified, not shipped: it opens after the first vault and its security architecture is externally reviewed.
Security
Cryptographic proof of origin and integrity for every stored artefact.
Content encrypted in transit and at rest, with keys under the owner's control.
Explicit, auditable custody — who holds a memory, and who may unseal it.
We research security approaches designed to remain resilient in the era of quantum computing.
Trust & Data Governance
A memory vault is only worth what its governance is worth. This is the model we are building against — and what we will publish in full before the first pilot.
European infrastructure, with data residency contractually stated for every pilot and institutional client.
Encrypted in transit and at rest, with a client-side encryption path for the most sensitive archives.
The account holder controls the keys. Recovery is designed around verified heirs, not around us.
Deletion is real deletion, propagated to backups within a published window.
Your archive leaves in open formats at any time. No lock-in on a lifetime of memory.
Digital inheritance is a first-class feature, aligned with GDPR and succession law in our entry market.
Bottle on the Sea is at pre-seed stage. The commitments above describe the architecture we are building and will be independently reviewed before general availability.
Cryptographic longevity
A vault built to hold memory for fifty, a hundred or two hundred years has to be designed today against the cryptography of tomorrow. We do not claim to be quantum-proof — nobody honestly can, over that horizon. We claim something harder and more useful: an architecture that can change its cryptography without losing the archive.
Built around the NIST post-quantum standards FIPS 203, 204 and 205 — ML-KEM, ML-DSA and SLH-DSA.
Cryptographic primitives are replaceable. Re-encryption and re-signing are planned operations, not emergencies.
Classical and post-quantum mechanisms combined during the migration period, as public guidance recommends.
Long-lived archives are exactly the target of that attack. Designing for it late is designing for it too late.
Preservation proofs are separated from confidentiality, so integrity survives a primitive being retired.
The cryptographic architecture is reviewed by a specialist before any security claim is published.
Built for cryptographic longevity — not "quantum-proof forever". We will publish the architecture before we advertise its strength.
Institutional pilot
Digital custody solves storage. Succession law solves transmission. Neither works alone. We are preparing a pilot programme with notarial practices to test the combination: verified identity, certified instructions, and an encrypted vault that executes them.
No notarial partnership is announced or signed at this stage. This is an open call for pilot participants, run under confidentiality.
Use Cases

From vision to platform
Bottle on the Sea has defined the technological and product architecture for a new category of digital heritage infrastructure. We are now seeking pre-seed funding and strategic partners to build the MVP, launch validated pilot programmes and establish the foundations of long-term digital preservation.
