Kaula supplies Fusion Reference Implementation 1.0

Kaula Inc., a Distributed Ledger Technology company(HQ: Tokyo  Japan, CEO: Katsuji Okamoto) is pleased to announce Fusion Reference Implementation (“RI” hereafter) 1.0 which is a set of source codes and associated design materials of Ethereum smart contracts and dApps (distributed applications).

RI 1.0 has been constructed through Kaula’s application design and development experiences including BRVPS (an automotive blockchain system) which has EV Battery Charging Payment and EV Battery Trading applications. 

A sample of EV battery application

RI is a kind of sample smart contracts and dApp programs for real usage. Using it, you can only modify and/or add your application-specific programs in order to quickly develop your blockchain applications.

You can also apply the RI 1.0 to other fields than EV Battery or automotive applications, because RI is made up with the structure of core (common or application independent) and app-specific parts.  

Kaula will also extend and add other design patterns to the Reference Implementation.

For more detailed information on RI 1.0 available for potential customers who have experienced PoC of blockchain applications and need some development environment, please contact us from here .

Kaula develops DataWallet

Kaula develops DataWallet
to manage Blockchain dApps and eWallet

Tokyo, 2018.12.3.     Kaula Inc., a Distributed Ledger Technology company (HQ: Tokyo, Japan, CEO: Katsuji Okamoto) is pleased to announce its developing DataWallet.  Under a circumstance that Blockchain applications are almost ready to be used for industries, accessibility to an application as well as usability of application itself becomes important, that is how easy to access and start my applications and manage my private data. DataWallet is a dApp which invokes dApps of blockchain that an individual user holds, and which is self-sovereign governed by each user.

DataWallet has an ERC20 wallet in its center to manage operation and control of value transition between entities, that is one of the core natures of blockchain. It also holds a set of dApps information in the MyDapps Directory, including user private data that will be referred by the dApp, location (because dApp does not necessarily run on the same device) and config/init data of the dApp.  All data are symbolically stored and converted to the unique ID via a name services like ENS. As user authentication uPort is used as default.
It is planned that you can purchase dApps through Apps Store and relevant information is stored into the MyApps Directory.

Fig.1 DataWallet and its execution

DataWallet was originally considered for applications of ABCC (Automotive Blockchain Consortium) and was greatly upgraded to be a general model of DataWallet. It can be used for various situations including
(1) DataWallet on a Smart Phone for personal use
(2) DataWallet on PCs for enterprise application execution
(3) DataWallet on an edge computer in an automotive vehicle for IoT applications

A beta release of DataWallet will launch in early 2019, and its usability to be examined by several blockchain applications.
Further development is also planned to support Interoperability of blockchain applications even in limited environments.

Kaula develops “Document Eigen Framework” to make Self-sovereign Private data stores


Kaula have been developing and introducing Factom and its unique autonomous blockchain for record managemen of any documents and data. Factom is so powerful and easy to use to build applications and to add blockchain capability to existing applications. Kaula applied Factom to access record management of  Japanese Security number system in local govenments.

Through this business Kaula has been noticed that we need some secured private data store of such as healthcare, academia, etc. It should be self-sovereign, managed by himself (herself) but not by any third parties, could be modified (corrected) and deleted (forgotten if case data were not longer required).
The above capability is so widely needed. We call it “Passports” and its embodyment is Medical Passport (for healthcare segment), Academia Passport, Govenment Passport and so on.

Kaula’s “Document Eigen Framework” (EDF)

Kaula develops “Document Eigen Framework” to easily build such Passports. Plese see the figure below.
Any access footprints, including creat, update and erase, are kept in Blockchain ( such as Factom) and it is anti-tamperd, transparent and auditable. The private data themselves are stored in any place accoring to user requirements, sometimes in local store, sometimes in public store with encryption. Passport ID is given to the personal, and SSO is coordinated.
It is self-sovereign, poratble, completely managed by the personal, and GDPR-compliant.
It addition, EDF supports “Trustee model” as well.

Document Eigen Framework

“Document Eigen Framework” will be soon available for application builders.

Business alliance between Kaula and AZAPA

Business alliance between Kaula, Inc. and AZAPA Co., Ltd. aiming to build blockchain technology and service in the automotive market

Kaula, Inc. (HQ in Chiyoda-ku, Tokyo, CEO: Katsuji Okamoto, hereinafter referred to as “KAULA”), a blockchain technology company, and AZAPA Co., Ltd., (HQ in Nagoya, Aichi-ken, CEO & President: Yasuhiro Kondo, hereinafter referred to as “AZAPA”), a leading company in the automotive field, have concluded a business tie-up. We will work on development of practical application services that increase economic values of data derived from automobiles by adapting the blockchain technology.

Background of the Alliance
A paradigm shift of the automotive market is near at our hand, especially due to China’s EV shift. Regulations on CO2 emission is being required around the world to solve serious air pollution problems, shifting from gasoline cars to electric cars is going on and EV battery management attracts attention now.
Battery is the heart of EV. It is the most expensive, heaviest and dangerous. KAULA and AZAPA together will make a new sharing economy around the battery to maximize its value and manage its life cycle, acquiring battery residual value data, distributing battery usage forecast using AI and writing them into the blockchain to guarantee authenticity and non-tampering.

Overview of BRVPS
The Battery Residual Value Prediction System (BRVPS) acquires data from BMS (Battery Management System) such as temperature, humidity, pressure, voltage, current, etc. in the battery unit and information from OBD (On-Board Diagnostics) and then stores them in the battery residual value forecast engine. BRVPS steadily executes AI/ML and writes the results to blockchain which EV/battery owners and users can access via cloud services. This enables you to extract the maximum battery value through freely accessing the present and future SOH (State of Health), including charging efficiency, and usage forecasts based on the past battery usage tendency.

The Next Deployment
Through cooperation with EV and battery manufacturers, we aim to develop new markets centering battery data. Implementing each step of EV and battery supply and demand balance, energy consumption planning, reservation, use and settlement, we accelerate the spread of EV and create additional services so that EV and battery owners and users can switch from consumers to prosumers.
In addition to the rising of global environmental consciousness, automatic driving and other technologies, newly services have been born and growing rapidly. We will broadly provide highly value-added services through KAULA’s blockchain technology and AZAPA’s automotive technology and network to build a new business model together.

Establishing a Consortium
We will set up a consortium to form an ecosystem, ahead of mega platform formers, to establish “IoT-blockchain based technology” aiming at a practical service model which covers from sensing to data utilization.
The paradigm shift surrounding automotive industry is progressing and closely related to the deepening of IoT, and the economic value of data obtained from automobiles has already been widely acknowledged. The current telematics, however, the type and granularity of acquired data are not standardized and its service is so limited. We will together promote applications created by utilizing data and their standardization including blockchain and security as backplane technologies.
