HOME / WHY ANONYMOUS AGE VERIFICATION

Not collecting personal data
is the strongest security.

The moment you adopt age verification, your company inherits the duty to collect, store, and destroy personal data. BBaton takes a different approach — it never receives personal data in the first place. Only an anonymous claim is passed on like a baton: nothing to leak, nothing to guard, nothing to be liable for.

00 · The Problem

Conventional verification is
a liability for your business.

Identity-based verification confirms the user — and makes every piece of their personal data your responsibility.

RISK 01 · Breach liability

Every record you collect can leak

The moment you store names, birthdates, and phone numbers, you owe encryption, access control, and destruction duties. One incident costs more than the entire verification system.

RISK 02 · Signup drop-off

Every KYC step loses users

Each demand for real names and phone verification narrows the funnel. On services where users expect anonymity, it is the top reason for abandoning signup.

RISK 03 · Recurring cost

Per-call fees keep stacking up

Conventional verification bills per call. As traffic grows, verification costs grow in lockstep.

RISK 04 · Compliance burden

Holding data is itself regulated

Privacy law, network law — the more data you hold, the wider the regulations and audit scope you must satisfy.

THE BBATON APPROACH
FLIP · Zero data

Receive nothing, lose nothing

BBaton delivers a single claim: adult status. No name, no birthdate, no phone number ever reaches your servers — the data that could leak simply does not exist.

FLIP · Still anonymous

Users pass verification anonymously

After a one-time identity check, users prove adult status anywhere while staying anonymous. Your KYC-free signup flow stays intact.

01–04 · Why BBaton

Four reasons
to adopt.

Anonymity, security, conversion, and cost — four tangible effects of a structurally different design.

01 · ANONYMITY

One thing is delivered: adult status.

BBaton stores only whether an anonymous user holds a verification, and passes it on like a baton. The response your service receives contains not a single piece of identifiable personal data.

  • Minimal privacy-policy burden — there is nothing to collect
  • Ideal where anonymity is expected — community, content, web3
  • Ruled compliant by MOGEF as a method that uses no resident registration numbers

02 · SECURITY

Data on the device,
records on the blockchain.

Personal data lives only on the user’s device; verification records are written anonymously to the Base (L2) public blockchain, where they cannot be forged. Everything is managed solely via secret key.

  • No central trove of personal data to hack
  • On-chain records — every verification is transparently auditable
  • Patented blockchain-based verification management · ISO 9001 certified
