TOKYO – April 25, 2018 – ​Today Tech Bureau, Corp., a fintech and cryptocurrency solutions company, announced that in March and April it participated in a Proof-of-Concept (POC) that made use of mijin blockchain technologies within a support application for side-business activities. What is more, in undertaking the aforementioned project, Tech Bureau recognizes its collaboration with the following entities: Nippon Information and Communication Corporation (President/CEO: Yujiro Hirose; hereinafter referred to as “NI+C”) and PERSOL CAREER CO., LTD. (President/CEO: Taro Mineo; hereinafter referred to as “PERSOL CAREER” and was previously known as “Intelligence Ltd.” ).

Project Background

Much attention is now being paid to the blockchain in that it represents the technological basis of both crypto currencies and initial coin offerings. What is more, in that it offers “tamper-resistant,” “zero downtime” *1​a​nd “smart contract”​*2 functionality, etc., the technology can be applied to a broad range of different services. On this occasion, as the three companies collaborated with one another, the focus of the POC itself was the technology. Specifically, with its involvement in systems integration, NI+C considered the issues so as to verify the possibility of services being realized, while Tech Bureau examined matters from the perspective of such services being developed based on the mijin blockchain technology itself. Meanwhile, the participation of PERSOL CAREER was based on its position of being a company that is involved in personnel services.

*1​“​Zero Downtime” refers to there being no interruption of the services, To achieve such goals, redundancy becomes a critical requirement at every level of system infrastructure.
*2​“​Smart Contracts” refers to a contract build on the blockchain that can’t be initiated and/or transactions can’t occur until all appointed cosigners agree to the contract.

 

POC Summary & Results

A support application for “side-business activities” was developed for the POC on this occasion in that expectation exists that such activities when undertaken by individuals represents a way in which to resolve the social issues of a declining workforce and insufficient innovation. From the corporate perspective, meanwhile, the systemization of side-business activities by companies will become a serious issue with respect to their management of labor affairs. Additionally, concerning the management of their own time, a significant burden shall be placed on the shoulders of company employees who choose to engage in side-business activities. Accordingly, on this occasion the POC collaborators utilized mijin blockchain technology to develop an application capable of managing work attendance data. They then took steps to confirm that the application could resolve the following issues.
*On this occasion, the POC testing made use of mijin, an versatile private blockchain technology developed by Tech Bureau.

 

Issues Confronting Companies POC Results
Original employers cannot establish the situation regarding an individual’s employment at other institutions, and thus it becomes very difficult to manage their working hours The working hours data for hours worked at both original employers and at the sites of side-business activities can be managed on a single blockchain. Accordingly, it was confirmed that affairs straddling different companies can be managed
As a result of incorrect and fraudulent reporting of working hours, there is a risk of double-duty being recorded Through exclusivity controls utilizing tokens*3, it was made impossible to record simultaneous clocking-on at multiple companies. Such functionality can be linked to preventing the claiming of double-duty
Issues Confronting Individuals POC Results
There is the burden of individuals having to manage and report their own work details Using the same tools, it is possible for companies to mutually manage work attendance between them
There is the risk of incorrect and fraudulent calculations of working hours being made on the part of original employers Through the use of multi-signatures*4, both employers and employees can retain data, thus excluding the risk of impropriety on the part of either party

 

*3​“​Tokens” are assets that can be kept as digital data. Multiple asset tokens can be issued, distributed and managed almost without restriction by mijin.
*4​“​Multi-Signatures” are a system whereby, in order for a single transaction to be completed, multiple approvals (e-signatures) are required. Such functionality has been incorporated into mijin as a basic feature. Moreover, the same functionality is also able to respond to complex workflows and user authority management.

 

It should be noted that “NI+C Accelerator 2017” was conducted by NI+C and Tech Bureau with the support of Crew Inc., and since that time open innovation activities that make use of mijin has been promoted. Thus, the POC carried out on this occasion was an extension of those activities.

 

Future Developments

In light of the results, with their aim being to provide society with even better services, going forward the three companies shall continue to conduct additional POC projects with a view to also realizing the creation of new services that make use of mijin blockchain technology.
