Two Token Model – A Cryptoeconomic Approach For High-yield, Yet Stable Transaction Networks

On December 6, 2017, game company and distributor Valve announced that its gaming platform Steam is no longer accepting Bitcoin as a payment method. The company explained that Bitcoin transaction fees have gone up to nearly $20 per transaction last week, “compared to roughly $0.20 when we initially enabled Bitcoin.” At the same time, CryptoKitties burned up 15% of Ethereum’s gas, causing a mid-level congestion and increasing in-game fees.

Since we have been working on some ICO projects with Datarella over the last months, focusing on cryptoeconomics and token design, and we have been discussing the stability of a token within the Building Blocks project we’ve launched with UN’s World Food Programme, we felt the need for a model that would allow a high-yield return for investors on the one hand, whilst guaranteeing the stability and a proper functioning of the specific application(s) at the same time.

Two Token Model TTM Thesis
Decentralized networks need a token model that

  1. guarantees a stable cryptoeconomic mechanism to exchange assets, services, time and money between peers, and, at the same time,
  2. allows investors to reap large economic benefits, and, therefore
  3. allows an overall story of combining a cooperative/post-capitalist model with a pure capitalist play by technically separating both aspects through the representation of two dedicated tokens.

Proposed Solution

A) Two-Token Model

The network features 2 different types of tokens:
a) a core token (CT) that is tradable at crypto-exchanges,
b) an application token (AT) (per application)

The only function of the CT is that of a currency. In all of the network’s potential applications, there is one overarching CT.

The AT is designed depending on the respective application’s requirements. It is the only token that allows the usage of the respective application. It is not listed at any exchange. Potential listings of ATs probably could not be prevented technically, but by regulation: The network defines the listing of AT’s as not allowed and will exclude applications that behave otherwise. Organizers of applications that already have a token will be offered to exchange their tokens for AT. Additionally, they can be awarded CT depending on their applications’ asset values.

B) Token Issuance Mechanism

Initially, there will be two events that happen at the same time:

  • SAFT of CT to (accredited) investors
  • One-time distribution of (free) AT to interested potential network application users (comparable to a basic income)

The Token Story

A (revenue-driven, high-yield) SAFT will finance the development of the network and serve as the initial AT supply of the network. Within the first applications running, AT holders can earn additional AT, and, directly derived from that, additional CT. The intensity of use and supply of AT represents the intrinsic value of a CT.

This model of a clear, technical separation into  – and combination of – a speculative and an application part should serve the initially conflicting interests of both categories of the network‘s stakeholders: the potentially application-interested majority of AT holders and the potentially solely commercially driven and high-yield-driven investors who hold and trade the CT.

Every app token holder (ATH) will receive CT’s additionally to their AT’s, if the intensity of use of the application reaches a certain threshold. As long as the intensity of use is above this threshold, the ATH will receive additional CT’s, scaling with their intensity of use. When the intensity of use sinks below the threshold, there will be no CT’s awarded further on.

Definition of Intensity of Use IoU Criteria

As mentioned, ATH are being rewarded CT depending on their intensities of use of the application(s). There are several aspects of defining an “intensity of use (IoU)” in a good way. First, an ATH could use a specific application very frequently. This could add to her IoU. Then, the ATH could move huge assets within an application. Again, this could add to her IoU. Further on, an ATH could use an application in a way that leads to a higher IoU of another application. This would lead to trans-application elements of the IoU’s algorithm. Then, there are further aspects, s.a. hoarding/inflation, etc..

Model Attractiveness

The definition of the IoU algorithm is one key aspect of this token model. On the one hand, it seemingly is the most complex problem to solve for the network. On the other hand it offers the opportunity to create one single algorithm that is completely variable in design and can be tweaked throughout the lifespan of the network without any need for changing the structure.

Due to the fact that the AT is not tradable, and the IoU algorithm prevents the ATH from hoarding and other unintended use, it can be regarded as stable.

The CT, in turn, is a tradable token that entails no other rights than being exchangeable with other currencies. The prize of the CT will be defined by market forces alone. This pure market-driven nature of the CT, combined with the value(s) of ATs, makes the network’s model highly attractive for application-focused users, as well as for investors.

We have intensely discussed the TTM within our professional and scientific network, and we have not found severe weaknesses that could prove to become showstoppers. However, we invite you to prove otherwise! Please provide us with your feedback on the Two Token Model – thank you!

UN’s World Food Programme WFP Appoints Baltic Data Science As Partner In Building Blocks Project

Our subsidiary Baltic Data Science (“BDS”) has formally been appointed by WFP to support them on the scale-up of the Building Blocks project.

We are very proud to announce that our close development partner and Polish subsidiary BDS has formally been appointed by the World Food Programme for the further roll-out the existing Building Blocks platform. At the beginning of the this year, we together with our partner BDS started to build a blockchain-based proof-of-concept for WFP and transformed it into a fully-functional blockchain-based transaction platform in Jordan. The inhabitants receive food vouchers that can be used in the village’s supermarket.

So what are the benefits compared to traditional transaction payments? Thanks to the blockchain technology, our innovative system provides higher transparency of aid accounts for beneficiaries and easy tracking of transaction which helps to lower the effort of bookkeeping for vendors and WFP. The biggest, however invisible, advantage is a minimized risk of fraud or data mismanagement.

We are excited to follow the next phase scale-up of the transaction platform and want to thank WFP for their trust and wish both partners a successful roll-out.

If you want to learn more about our services or specifically this project, please contact us at or BDS at

Building Blocks – How the World Food Programme is harnessing Blockchain technology to deliver humanitarian assistance

What started with a Proof-of-Concept in Pakistan in early January this year, has been transformed in a fully functional Blockchain pilot being rolled out in Jordan in May, 2017. The Building Blocks project not only demonstrates the power and the impact of blockchain technology and its potential to enhance the lives of millions  but it is proof of the technology’s potential for efficiency gains for a humanitarian agency, such as WFP.

Based on the early, however robust prototype field tested in Pakistan, the Building Blocks pilot in Jordan now serves thousands of households in a Jordanian refugee camp Tazweed village. The inhabitants receive food vouchers that can be used in the village’s supermarket. The seamless integration of the existing iris scan identification technology into Building Blocks system allows the  existing processes to stay in place without any need for changes for the beneficiaries,  the supermarket nor WFP personnel. The only visible differences are a higher transparency of aid accounts for beneficiaries and easier bookkeeping for supermarket managers. The biggest, however invisible, advantage is a minimized risk of fraud or data mismanagement.

The economic benefits of harnessing Blockchain technology can amount to several million US-Dollars for the Jordanien refugee camp population, alone. The goal of the Building Blocks pilot is to demonstrate a fully-functional Blockchain solution that can serve as a role model and architecture for similar humanitarian projects worldwide and a base to develop other use cases.

The Datarella team wants to thank the WFP team, the IrisGuard team and our partners over at Parity Technologies for the great cooperation: from the beginning, we felt being one big team with everybody helping the others out when they needed it. Other than with this collaborative effort a project like Building Blocks would not have succeeded: Blockchain technology still is in its infancy and basic conditions in the field have proven to be challenging. Again: thank you very much for the opportunity to demonstrate the power and the real impact of Blockchain.

If you are interested in the Building Blocks project you might consider visiting our Ethereum Meetup on May, 16 .Here we will present more details and especially share our experiences gained in Tazweed village, Jordan
