Digital Stamps

We aim to protect you from spam & phishing using "digital stamps". These contain the sender's real identity and a potential fee, if the message is sent by someone you don't know.

  • You keep your existing email provider
  • You set your own fee for receiving unsolicited emails
  • You receive stamps with value from senders you don't know
  • You can sell your stamps for real money

A global $50bln annual problem

It is estimated that spam and phishing costs global economy $50bln every year and in excess of $20 billion in the USA alone. It costs society far more with the distress scams and lost money which causes individuals and families whose dreams and security can be wiped out through criminal activities.

YooPing let's you check incoming email's DIGITAL IDENTITY in order to PROTECT you from spam & phishing.


Earn money

If someone you don't know tries to send you an email, they have to create a digital stamp proving their identity.

You determine the cost of the stamp, so if it's too high, the sender may not send you the message. This stops spam, but people who value your time and marketing companies may decide to pay your fee.

You decide if you want to accept, reject or block future emails from the sender.

You can keep the stamps you receive, to reuse them, or you can sell them for real money.


Partners - we are proud to have some great partners.

At the heart of the YooPing service are 4 core components:


Digital Identity

Anyone who sends or receives digital communication needs to prove they own the email, telephone, social media etc account for which they are initiating or receiving digital communications. Through automated processes, our service can ensure the owner can link to accounts. In addition, through partnerships we aim to create a trust score and "digital passport" which allows recipients to check the senders credentials before trusting the communication they are sending. Since the communication is signed, once this is established, the communication cannot be tampered with.


The user registry

This is a decentralised user preference registry, where everyone can create (or use default) rules for their communication. The data is encrypted, and calling it never returns contact details. Instead, the API takes a signed sender address (e.g. email address or telephone number) and recipient address and returns a small, signed token whether the recipient will "accept", "reject" or "accept given a fee". This gives decentralised assurance that the sender "owns" the sender address, the "trust" that has been missing in digital communications.


The escrow service

This service holds the sender risk until the communication is delivered to a recipient. It allows the recipient to potentially refund their fee (minus partner/platform fees) to the sender. For example, by default all emails will be rejected unless a potentially refundable 25 cents commitment is made by the sender. If the recipient accepts and whitelists the email, most of the fee is refunded. If not, the recipient and the communication partner shares the fee. If the communication is not delivered, the fee is refunded after a period of time.


The API & protocol

The api calls the user registry and, based on the user defined (or default rules), always returns a small signed response token.
The response is either "accept", "reject" or "fee".

"Accept" - I accept your communication.
"Reject" - I reject your communication.
"Fee" - I accept your communication, if you are prepared to pay my fee.

The sender can now decide whether or not to proceed with the communication.

If a fee is required by the recipient, an API call is made to the escrow service which creates a smart contract committing the fee from the sender to that recipient.The sender's communications are sent, along with a signed token.

Blockchain & Communication

We "positively disrupt" digital communications, for the benefit of users and communication providers, using blockchain and smart contracts. Blockchain provides distributed trust through consensus. Smart contracts provide commitment (a small and potentially refundable financial risk) by the sender. Combined, they provide the communications industry with the assurance everyone benefits from.

Using a lightweight protocol and fast, secure API a sender checks on what terms a recipient allows digital communication. A signed token may be returned containing a financial obligation and the sender can decide if they want to proceed or not.

Smart contracts act as an escrow service ensuring the communications are established transferring or returning any financial risk.

Our service can be integrated by every communication provider... every mobile handset maker, social media provider, instant messaging service, email client developer, streaming video provider. By providing users with the tools to control their communications preferences, they earn a share of the value the user generates.
