Peer sharing · secured by ELAI

Idle storage is everywhere.
Your peers can use it.

A laptop has gigabytes idle. A mid-size IT department has terabytes. Daisy unlocks both — with cryptographic attestation on every contribution, every retrieval, every custody handoff. Built so individuals and corporate IT both come out ahead.

Contribute capacity

Install Daisy. Scan your drives. Pick what to contribute — file by file or whole categories. Every contributed byte earns cooperative storage credit, signed and posted to the ledger.

For: individual contributors (today) · corporate IT pilots (Q3 2026, contact us) · operators of always-on anchor nodes (rolling)

Install Daisy

Free for individuals. macOS today. Win + Linux soon.

Coming Q3 2026

Store with proof

Back up your data across the cooperative. Blind custody by mathematical construction — hosts can't see what they hold. Erasure-coded across fault-domain-diverse nodes. Every retrieval signed both ways.

For: regulated businesses needing audit trails · Tennessee orgs requiring data sovereignty · anyone tired of "trust me" cloud

See how it'll work

Phase 4 — peer protocol in development.

The question on your mind

"If my peers can use my drive,
can they see — or steal — my stuff?
"

Short answer

No. And it's not a promise — it's mathematically impossible by design.

Nobody ever holds your files. They hold encrypted ciphertext fragments. Even if they tried — even if AmericaFirst4Us were compelled by a court — the math prevents the lookup.

What actually happens when you store a file

Three operations, in order, all before any byte leaves your device.

1

Encrypted on your machine

Your file gets encrypted locally, with your own key, before anything goes anywhere. Custodians never see plaintext. AF4U never sees plaintext. Your ISP never sees plaintext.

2

Erasure-coded into shards

The ciphertext is split into N shards. One shard reveals nothing. Even all N shards reveal nothing without your decryption key. Each shard is just random-looking bytes.

3

Distributed to peers, blind

Shards go to fault-domain-diverse custodians. Each signs a receipt over the hash, not the contents. They prove they're storing something — they cannot know what.

Compare to what you're used to

Cloud providers always say "your data is encrypted." Read carefully — by whom, with whose keys?

Who can read your file? AWS / Google / iCloud BackupTN cooperative
The provider Yes — they hold the keys (or can compel KMS) No — operator has no path to plaintext
A court order to provider Provider can be compelled to decrypt Nothing to compel — operator literally cannot
A malicious employee Insider risk is real, mitigated by policy No insider; nothing to insider
Your peer who holds a shard N/A (single provider, no peers) No — they see ciphertext, signed-blind
A hacker breaching the operator Catastrophic — keys + data both present Negligible — no keys, no plaintext anywhere
You (with your key) Yes Yes — the only party who can

"Okay — but can a peer steal it? Or just refuse to give it back?"

Steal: nothing to steal

They hold one encrypted shard. Even all N shards don't decrypt without your key. AES + Ed25519 — same crypto your bank uses. Brute-force is computationally infeasible.

Refuse: erasure coding handles it

Files are reconstructable from K of N shards — lose a few peers, your data's still intact. The protocol re-replicates automatically to maintain target redundancy.

Lie: the receipts catch them

Custodians sign a receipt when they accept a shard. If retrieval fails, that signature is tamper-evidence on the public ledger — bad actors get revoked and lose all future cooperative storage credit.

Even if AF4U is hacked

We have nothing to steal. No keys on our servers, no plaintext anywhere on our infrastructure. The worst a breach could do is post a defacement — your data is safe by virtue of never being in our reach.

For business

Storage with receipts. Not promises.

Cloud providers ask you to trust them. Auditors won't accept that. Daisy generates Ed25519 receipts on every action — designed to support the audit trails your compliance program already needs.

A typical 200-person IT department
200 employee laptops 7 GB each 1.4 TB
12 file servers — free disk 2 TB avg 24 TB
3 SAN arrays — unallocated 8 TB avg 24 TB
Idle capacity, already paid for ~49 TB
📋

Audit-grade trail

Every storage transaction produces an Ed25519-signed receipt from both requester and custodian. The pair posts to a tamper-evident ledger. Designed to support HIPAA, SOX, CMMC, and PCI-DSS audit-trail requirements — bring the receipts to your assessor.

💸

Cost economics that invert

Most IT shops have more idle capacity than their backup needs. Contribute 50 TB, consume 5 TB — you're net positive in the cooperative. Storage stops being a cost line and becomes a balance-sheet asset.

🇺🇸

Sovereignty by design

Domestic-only custodian selection. Region, jurisdiction, and fault-domain filters at the protocol layer. Your contracts and regulators say where the data goes — the cooperative respects that at the math layer, not in a policy doc.

🚪

No vendor lock-in

Open protocol. Multi-custodian. Open-source daemon. Files are encrypted under your keys before they leave your machine. Migrate out at any time, take all your data — no export fees, no rebuild, no permission needed.

🌐

Resilience that compounds

Erasure-coded shards distributed across geographic, ISP, and power-grid fault domains. An AWS us-east-1 outage doesn't take you down — neither does a regional ISP failure, neither does any single cooperative member going dark.

♻️

Sustainability you can show

The cooperative doesn't build datacenters — it reclaims capacity already manufactured and powered. Lower marginal carbon per stored byte than any cloud provider's lifecycle analysis. ESG-reportable, with the same signed ledger as audit.

Cooperative economics

Positive-sum by construction.

Cloud storage is extractive — every new customer pays the provider's shareholders. The cooperative inverts that: every new participant makes the network cheaper, more durable, and more provable for everyone already in it.

+1

Each new contributor expands shared capacity

A SaaS adds a customer → provider extracts more rent. The cooperative adds a contributor → the shared pool grows and per-byte cost falls for everyone. Network effects flow to participants, not to a corporate parent.

×N

Each new fault domain multiplies durability

Erasure coding works better with diversity. A new contributor in a new region, on a new ISP, on a new power grid improves recovery odds for every file already stored, not just their own.

Each attestation strengthens the ledger

Every storage transaction posts a signed receipt. The ledger accumulates evidence of honest behavior — auditable, tamper-evident, public. The longer the network operates, the stronger the proof of reliability becomes.

0

Zero net new infrastructure built

The capacity already exists — on laptops, file servers, SANs. The cooperative is a coordination layer over hardware that's already manufactured, already powered, already paid for. No datacenter capex. No new carbon footprint.

How it works

Four steps. Under three minutes.

Same install pattern as enrolling a chip card on verifythecard.com — small local helper plus a browser extension.

1
Install

One-line curl install plus the Daisy Chrome extension. No sudo. Runs entirely in your user account.

2
Scan

Daisy walks Downloads, Trash, Caches — and reads partition tables for unallocated space. Read-only.

3
Choose

Per-file or per-category checkboxes. Running total updates live. Nothing happens until you click Claim.

4
Claim

Files move to Trash (recoverable). DDS sparse container created. Capacity attestation signed and posted to ledger.

The honest objection

"Why should I trust some internet site
telling me to curl | bash?"

You shouldn't — not on our word. Curl-pipe-bash from an unfamiliar domain is a legitimate red flag, and "trust me" isn't a security model. Here are the receipts you'd need to actually verify Daisy before running anything.

👁️

Read the source before you run it

curl https://backuptn.com/install/install.sh — no pipe to bash. Read it. Diff it. Grep it for anything that doesn't look right. Same for the daemon: tar -tzf dds-bridge-bundle.tar.gz lists contents without extracting, then read daemon/dds-daemon.py — plain Python, no obfuscation, ~1,000 lines, no eval, no exec.

🔏

Verify the corporate Ed25519 signature

Every release artifact ships with a detached signature from the AmericaFirst4Us corporate Ed25519 key, published at americafirst4us.com/keys/. Verify with openssl pkeyutl -verify or any Ed25519 tool. If the signature doesn't validate, don't install. Same key that signs every ELAI ledger entry.

🏛️

A real, traceable company

AmericaFirst4Us Inc. — Tennessee corporation, principal office in Franklin TN, registered agent in Memphis. Look us up in the TN Secretary of State business records. Not anonymous, not a shell. If anything goes wrong, there's a real entity to send the lawyer after.

🚫

No sudo. Lower blast radius.

The installer asks for zero admin privileges. Everything lives under ~/Library/ — your user account. Nothing in /usr/local, nothing in /Library/, no system-wide registration, no kernel extensions. If anything was malicious, the blast radius is your user account, not your machine.

🧪

Test in a sandbox first

Create a fresh macOS user account (System Settings → Users), log in as that user, run the install, watch what happens. Confirms zero system-wide impact, lets you inspect the file footprint, then you delete the user account when done. Or run it in a VM (UTM, Parallels) — same workflow.

↩️

Uninstall is one command

./uninstall-dds-mac.sh --wipe-storage reverses everything: LaunchAgent removed, daemon deleted, native messaging manifests pulled from all browsers, sparse containers ejected and erased. ~10 seconds, no residue. Test, then trust — or test, then walk away.

What we don't yet have, but will: Apple Developer Program notarization (eliminates the Gatekeeper warning on first run — slated for Q3 2026). Public Git repository mirror for read-before-install convenience (today the source is inspectable via direct curl from this domain). VirusTotal community scan history (file is too new to have meaningful signal). We'd rather be honest about what's missing than oversell where we are.
vs. traditional cloud

A different shape of trust.

Not better-faster-cheaper marketing. Different architecture, different incentive shape, different math.

Trust architecture

Provable by construction.

DDS is built on the ELAI signing infrastructure that already powers chip-card enrollment, document signing, and federal-fraud demos across the AmericaFirst4Us ecosystem.

Hash-pair relational session gate

Every storage transaction produces a signed pair: requester's signature over the blob hash, custodian's signature over the custody receipt. Both go to the ledger. Either side can prove the transaction independently. Patent pending.

Blind custody by construction

Custodians sign hash(blob), not the blob itself. You can prove you stored something without ever seeing what you stored. Mathematical separation, not a policy promise. Patent pending.

Fault-domain-aware placement

Erasure-coded shards distribute across nodes selected for geographic + ISP + power-grid diversity. Regional outages can't take down a stored file.

Open source, locally audited

The Daisy daemon is plain Python — read it before you run it. The Chrome extension is unminified. Native messaging only, no telemetry, no analytics.

The foundation

What is ELAI?
Entity-Local Autonomous Intelligence

A trust membrane protocol. It wraps any entity — a person, a laptop, a server, a company, a chip card — in a cryptographic identity that can attest, evaluate, and handshake with any other ELAI-wrapped entity. Same protocol scales from a single chip-card enrollment to a 200-person IT department contributing 49 TB of storage.

The whole protocol fits on one line
<entity₁> | ELAI | ELAI | <entity₂> = gate

Two entities, each wrapped in ELAI, evaluate each other. The "gate" opens (1) when both sides agree the trust relationship is valid. It stays closed (0) for anyone unknown, anyone revoked, anyone whose attestations don't check out.

Four concerns. Nothing more.

Most "trust frameworks" sprawl into dozens of layers. ELAI is deliberately minimal — the whole spec fits on a long single page.

Identity

A deterministic hash derived from credentials. No server assigns it. Same credentials, same hash — anywhere, forever. Your identity belongs to you, mathematically.

Attestation

A signed proof of claims. Tamper-evident. Portable. Verifiable offline. Tamper with any field — claims, timestamp, nonce — and the signature stops validating.

Trust

A local graph per entity. No central authority. No blockchain. No global consensus. Each ELAI keeps its own record of who it trusts. Revocation is append-only and permanent.

Vault

Encrypted state. The server holds a blob it cannot read. Blind custody by construction — the same primitive that powers DDS storage. Custodian sees a ciphertext, never the cleartext.

Why trust ELAI?

Because there's nothing novel to trust.

📐

Standard cryptography only

SHA-256 for hashing. HMAC-SHA256 and Ed25519 for signatures. Standard primitives that the entire internet relies on every second. Zero custom crypto invented.

📜

Public protocol specification

The complete spec ships inside the OuiAmi app at /elai/PROTOCOL.md. ~300 lines, no hidden behavior, no proprietary extensions. Read it, implement it yourself if you want.

🚀

In production, not on a slide

ELAI signs chip-card enrollments on verifythecard.com, PDFs on 4PDFs.com, identity credentials in the Trust Suite, and storage custody on BackupTN — today, not someday.

🧱

No central authority to corrupt

No "ELAI server" you have to trust. No central CA. Each entity holds its own keys, its own trust graph. If AmericaFirst4Us vanished tomorrow, the protocol and your data keep working.

🪞

Origin: real consumer use

ELAI wasn't designed for a defense pitch. It was built for OuiAmi — a peer-trust network where ordinary users vouch for each other. Battle-tested by everyday humans before it touched any enterprise use case.

🔍

Patent-track formalization

Core ELAI primitives (hash-pair gate, blind custody construction) are the subject of active patent prosecution. That's not a marketing flex — it means the architecture has been examined by a patent attorney and looks novel enough to defend.

Who we are

Trust isn't built once.
It's built across products.

BackupTN doesn't ask you to trust an anonymous startup. It's one product in a portfolio of cryptographic-attestation tools from a Tennessee company that has been building this trust layer for years.

The company behind Daisy

AmericaFirst4Us Inc.

Tennessee corporation, principal office in Franklin, TN. Founded by Jesse Loflin — 27 years of federal IT systems engineering, building the cryptographic attestation tooling that now powers every AF4U product. Public corporate records at the TN Secretary of State.

One Ed25519 corporate signing key sits underneath every product. One public ledger records every signed event. Verify trust once — it composes across the whole portfolio.
