The protocol

Making trust verifiable

Classical internet security protects the connection. ETIP answers the question that remains after that.

TLS/HTTPS protects the transport. SPF, DKIM and DMARC filter email. But none of these technologies answer the question that truly matters:

"Can this domain or link be cryptographically verified?"

ETIP solves that. The protocol links domains and links to publicly verifiable cryptographic proof - independent of DNS providers, email providers or browsers.

vDOMAIN

Domain authenticity via whitelist and external anchoring.

vURL

Integrity and origin of public links and documents.

µAPI

Machine verification: the same check via JSON for systems.

Anchors

Publicly verifiable integrity anchoring - optionally via blockchain.

Applications

What does ETIP solve?

ETIP is sector-neutral and focuses on four concrete problems that classical security leaves unsolved.

Phishing

When "it looks real" is no longer enough. ETIP makes forged communications technically visible - attacks do not lead to a trusted outcome.

Look-alike domains

Subdomain spoofing, fake domains and QR phishing are directly detectable. A domain without verification is a domain without proof.

Secure link sharing

Via email, SMS, WhatsApp, PDF or QR code - the vURL proves by itself who it comes from. The recipient does not need to trust anyone.

Verifiable documents

Certificates, reports, datasets and public documents are independently verifiable - even without direct contact with the issuer.

What ETIP does not claim

  • - Not "unhackable"
  • - Not an identity or login platform
  • - No guarantee that attacks never occur
  • - No control over the content of communications
Components

Three layers, one protocol

vDOMAIN, vURL and µAPI are the three pillars of ETIP. Together they cover domains, links and system integration.

vDOMAIN

Domain authenticity

Domains are not trusted because they look right. They are trusted when they are explicitly listed in the EsReal® whitelist and their hash is publicly externally anchored.

More about vDOMAIN
vURL

Link integrity

Links and documents become verifiable through a cryptographic signature and a deterministic hash. Any change results in a different verification outcome.

More about vURL
µAPI

Machine verification

The same verification is available for systems via JSON. Add &json=true to a vURL and receive a full verification response.

Technical documentation
Core principles

ETIP in one sentence

ETIP makes trust verifiable rather than assumable - by linking domains and links to cryptographic proof.

Verification > Assumption

Trust based on proof, not based on appearance or reputation.

Publicly verifiable

No black box. Anyone can reproduce the same result, independently of EsReal®.

Protocol independent

Works on top of HTTP, HTTPS, SMS, PDF and QR - not tied to a single channel or provider.

No user identity

No tracking, no login, no personal data of recipients. ETIP verifies information, not people.
