Dear community,
dear colleagues!
Yury Morozov, CEO and Founder

Meet our new blockchain-based platform project.
Our company has been in telecom business for more than 20 years. Seventeen years ago we were among the first to create a platform for intelligent communication services, including fixed-mobile convergence.

For more than 18 years we have been successfully developing our own MVNO operator company with a client base of over 250,000 subscribers.
But as an MVNO operator offering its services only in limited areas, we are still unable to provide our clients with global roaming service despite many efforts.

Such a project would require us to sign contracts with about many hundreds global operators, pay a lot of money for technological convergence, check the quality of the services provided (voice, data, SMS, MMS, real-time billing, signaling, etc.) and also guarantee 300,000–500,000 commitments per year. Obviously, a project of such scale demands vast material and human resources.

To provide roaming services to our subscribers, we developed and brought into commercial operation a special OTA platform which makes it possible to remotely swap between mobile profiles of a SIM card, practically on the fly. It looks like you simply bought a new local SIM card and inserted it into your mobile phone.

We partnered with operators that currently provide services to their subscribers in more than 80 countries and who agreed to sell their mobile profiles, paying them deposits. In fact, we can already provide services to our clients at local rates without roaming in more than 80 countries. But there is a big inconvenience: buying profiles involves paying a deposit in each country, setting up online billing and, for many countries, completing a KYC form.

What we have today:

  • Operational platform that is able to upload mobile profiles on subscribers’ SIM cards;
  • Operational applet certified by one of the world’s largest SIM card manufacturers, Oberthur Technologies (OT) and Safran Identity & Security (Morpho), which determines whether the subscriber is in his home or guest network. Depending on the settings, it automatically swaps the home mobile profile for the one newly downloaded by our platform.
  • Beta version of the messenger with a playful name - Bubbletone - but serious technological capabilities. The Beta version is already available in the Google Play Market and the Apple App Store.

We chose a meaningful name: while the messenger is a full-featured working tool for users, it's as easy to use as blowing bubbles. We believe that this fun brand name will make our messenger more recognizable around the world.
The Bubbletone app contains more than 100 functions, each being in high demand by users. For our current project, the most important functions are:

  • Retaining your mobile number in the app during remote swapping of the SIM card profile. Subscribers will be able to receive incoming calls via an IP channel and also pay for local mobile service bundles in the visited country.
  • Using Bubbletone as the first client of a decentralized network based on blockchain technology (explained below), which we are developing.

Blockchain made it possible for us to radically change the rules of the game: we simply eliminated roaming.
Collaboration by mobile operators from different countries to make roaming possible involves huge expenditures on infrastructure support. In fact, the provision of services to a network subscriber in another network requires complex interactions between various equipment of the providers.

Our solution will let operators cast aside most of this infrastructure because many requirements, such as validity, integrity and indisputability, are covered by the technology itself. We're not daydreamers — we know exactly which minimum data are processed by operators during service provision and what the process looks like. In our system, the interaction between operators is encoded in a reliable and simple smart contract that contains everything necessary to provide roaming services.

Why should someone visiting another country pay 8–10 times more than a local? This is unreasonable. Plus, the poorer the country, the more expensive the roaming.

In our system we change the “push” paradigm, where operators “force” their subscribers into another operator’s network, for “pull”, where operators see the new clients themselves, securely identify them, and connect them to their own networks. Our smart contract is a separate incontestable agreement between two operators and the clients themselves that is enforced automatically.

In short, our code chooses a suitable operator for a client that will provide that client with roaming or any other communication service and creates a smart contract via a single transaction in which each party will “sign” for each action, attaching the necessary data to the contract every time (data will be securely encrypted so as to be accessible only by the parties.) Each “signature” is written into the blockchain and can be used as a reliable source of information on the status of the contract.

What are its benefits?

  • Transactions are incontestable. Operations conducted in blockchain are nearly impossible to fake or hide. This factor is important both for operators and their clients.
  • Data are safe. An entire blockchain is kept on many nodes within the network, in many copies, so the chance of data loss is extremely low.
  • The transaction error rate is minimized, as each action is controlled by a strict code on the operators’ nodes.
  • Less traffic is transmitted among operators — all interactions are now conducted via a decentralized p2p network.
  • Any additional code the system runs on is void of sensitive information that could be stolen. The only data requiring protection are the private keys of the participants.
  • Other benefits of a specific blockchain are given below.

We have analyzed many blockchain platforms and found them not entirely suitable for the telecommunications industry, as their transaction processing speed is rather low and we don't want to let our clients down.
Our platform of choice is Graphene, which underlies the decentralized exchange BitShares and such widely known projects as Steemit, Golos and EOS. Our developers promise us over 10,000 transactions per second, though, to tell the truth, 5,000 would be enough at the start. Also, the first prototype of the first node has been published on GitHub.

With our solution, operators will be able to publish their price quotes in the blockchain network and automatically get connected clients. The clients will receive all the data necessary for connection with just a couple of transactions and the operator will securely reserve the money to pay for the services. The amount of unnecessary traffic and hardware that will be freed up due to this solution is quite striking. This isn't magic or a trick, but a new class of algorithms with inherent ready-to-use functions for companies providing information services.

Consider the following benefits:

  1. When a SIM card is first sold, the home operator validates the client and sends encrypted digital proof of the client’s validity into a blockchain. As a result, when the client goes to another country, there’s no need to provide their ID to get another SIM card.
  2. Roaming operators will only need to promptly offer their services and price quotes, and the network will distribute this information and use it to bill clients itself.
  3. The offers will be regulated by the law of supply and demand, so technical and market share dominance will become less important than, for instance, the quality of service. Isn't this the cellular communication we always wanted?
  4. We are making communication services exponentially more affordable and are fighting inequality. The cost to use and support our system is significantly less than what you'll find with other operators today.
  5. Our system has many technological advantages (and some shortcomings, of course). For more information, see the project's white paper or simply ask us any questions you may have.

We developed a special economy for the telecom industry.
We have two tokens: One of them is stable and equals 1 SDR used in telecommunications. We named it SDR (SDR Token).
It's the unit of payment given to providers for their services, i.e., the price of services is measured in these units. Everyone needs SDR tokens, and their amount is unlimited, just like amount of services is unlimited.
The second token is UMT. It's necessary for creating smart contracts, and all service providers require it.
For more information on tokenomics, see our white paper.
While our blockchain platform is still under development, we have already received several requests from existing business projects to transfer their business processes to our blockchain. They need stable tokens and a quick blockchain platform, and, like ourselves, they got tired of the many intermediaries that sometimes earn more than those who actually provide services and conduct business. So, our project to kill roaming is only the beginning.

How it works

Telecom 2.0: Blockchain replaces old-fashioned and costly roaming technology totally by implementing smart contracts into mobile operators' interactions.

The Blockchain in Telecom is based on “Proof of Importance” consensus to process millions of smart-contracts between mobile operators around the world:

Visited operator
Visited operator
Any mobile operator
can publish its own tariff plans
as smart contracts ("Offers").
These Offers are visible to all
operators and their subscribers
Request for mobile
services abroad
Home operator
Smart-contract ("Request")
with Digital Identity hash
and Financial Transaction
It's enough to execute
the smart-contract
to receive money
and identify a visitor
Servicing the subscriber
directly by downloading
its own mobile profile onto
a SIM-card "over-the-air”
Blockchain Telecom part
Live demonstration of mobile carriers' interconnection via Blockchain.
New Offers and Requests are created and broadcasted in real-time mode, and a new mobile profile was downloaded onto SIM-card of a subscriber.
User’s Interface part
A brief demonstration how subscribers can be connected with local rates and LTE quality around the world.

The process of creating and executing of smart contracts is seamless for subscribers and takes about a minute. Direct connection to a local operator provides low rates and high LTE quality, with easy management using Bubbletone mobile app having 100+ useful functions.

Crypto-holders could setup own nodes to earn Universal Mobile Tokens (UMT) on smart contracts processing. Growing demand and limited offer of the tokens provide the great revenue stream for each participant:

Easy to Start
Millions of Smart Contracts

Which cryptocurrencies are accepted?

Payment options with our ICO include: Bitcoin, Ethereum, Litecoin, Bitcoin Cash, Dash

Which wallet should I use to receive tokens?

To receive UMT an ERC-20 compliant ETH wallet should be used, please note that ETH wallet should be your personal wallet as exchange wallets can’t be used. Please see the below link for available wallet options:

What is the goal of your project?

The goal of the Bubbletone Blockchain platform is to eliminate all long, complex and costly inter-operator roaming procedures and to create a new market for thousands of telecom carriers opening affordable mobile services for silent roamers. Our Blockchain in Telecom ecosystem provides direct interaction between mobile operators and service-providers via smart contracts.

Is your product already working? Do you have a prototype or a beta version?

We have a working beta version of our messenger application, it’s a fully operable modern messenger.

We also have our OTA platform for downloading third-party mobile profiles via SMS developed and running on a commercial basis with our partners in 80 countries globally.

We are currently finalizing on messenger’s convergence with blockchain to start launching smart contracts. Graphene blockchain platform is being currently developed as well, it’s 80% complete already.

Why do you have a blockchain in your project?

Blockchain made it possible for us to radically change the rules of the game in telecom: we simply eliminate roaming.

Blockchain is the basis of our solution, since the interaction between mobile operators is carried out through smart contracts. There is no need in expensive direct contracts and technical integration between network providers. This allows any cellular operator (including small ones) to quickly (within 24 hours) begin offering their services to subscribers of other operators and to provide subscribers with a global service at local rates.

How is your system going to expand?

The Bubbletone ecosystem will expand through 3 main agents:

  1. New mobile operators;
  2. New users of the BubbleTone messenger;
  3. New service providers (TV, music, cloud services, through bonus packages of mobile operators with several service providers in one package).
What are advantages for Node owners?

Node owners get income from smart contracts processing and also Node price increases itself with the quantity of smart contracts in our ecosystem.

Node is an asset. It’s like you buy house which increases in value and pays rent as well.

What are the advantages of BubbleTone messenger?
  1. For subscribers: make calls and use data during travel worldwide at great local rates with direct connection to local operators. No need to change your Sim or phone number. Access to unique offers from service providers all over the world and a variety of amazing features in BubbleTone messenger (audio/video/conference calls, crypto and fiat transfers within the system, etc.).
  2. For mobile operators: global status at extremely low cost and effort, bigger audience of potential subscribers due to visitors and tourists, more services for subscribers. Increase in revenue through distribution of value-added services
  3. For service providers: larger reach of potential clients, operations and marketing costs cut down.
How do I operate all these other Sims on my phone?

You don’t need any additional Sim cards, it works with just your current Sim. All you need is download BubbleTone messenger, and with its interface you will be able to choose offers from service providers and subscribe or cancel subscription for services at any moment.
