LABO Whitepaper Rev 1.4

Background

Very few, if at all had imagined what was taking place at the moment when Bitcoin was born in 2009. After 8 years, the market capitalization had gone from 0 to 70 billion dollars, which is accompanied by various projects launched around Blockchain technology. As of December 2017, The Cryptocurrency market as a whole has rapidly grown to 5,000 dollars. However there remains much room for further growth when compared to stocks, fiat, and gold, and the growth of the cryptocurrency market will likely continue.

Currently, Japanese investors account for much of the cryptocurrency market trade volume, which seems to indicate the beginning of assuming a role as the leader in the future of cryptocurrency. However, on the other hand, there are not many projects in Japan which utilize blockchain technology and distributed networks in the real sense.

Manipulation of information is rampant on the Internet today, and in mainstream media. Search results are naturally prone to manipulation by search engine companies, and crawlers, automations, and over-standardized methods have led to low quality articles placed in higher ranks in search results. You may have experienced, when you search, the top 10 search results were mass-produced low quality articles and you either give up the search, or move to the next page with very little expectation. This type of issue is a threat to the credibility of media.

LABO Whitepaper Rev 1.4

Information manipulation in media was an issue which stems from business models prior to so-called Web 2.0, and this may be solvable with the distribution of information resources. We have high expectations in Ethereum network Dapp and smart contract encompassed in it. Our goal is the Internet as an environment completely free from manipulation of information.

However, the current Internet is full of content from the Web 2.0 era which is comfortable at first glance, but consistently susceptible to information manipulation. We don’t seem to have free choice, but most are free of charge. Who would want to use a distributed network if it means such comfort will be compromised? We believe the question is reasonable. Many users currently have difficultly grasping this. That is why we will provide distributed network in the familiar form of messenger.

Cryptocurrencies increase in value, and the future of finance will shift from centralized to decentralized all over the globe. At the same time, blockchain technology will pioneer a brand new future. We think that many developers and users need to experience distributed network first-hand, operating with ease. We will hold an ICO to offer a solution for this. The “LABO project,” is the latest development in blockchain and distributed network technology.

LABO Whitepaper Rev 1.4

What is LABO

LABO is an open-source messaging platform from Japan as well as a social network utilizing the power of the Ethereum network. 10 years have gone by since the birth of Blockchain technology but one can hardly claim the technology has penetrated to the general public or adopted by the mainstream society.

LABO messenger is a user friendly mobile interface for typical smartphone users which provides a means to access Decentralized applications (Dapp) running on top of Ethereum network.

If we take “WhatsApp” messenger which is used by many people , we may be able to illustrate it better. In WhatsApp messenger, anyone can send and receive messages and “stamps” easily. Similarly, LABO uses distributed network technology on Ethereum network so that anyone can exchange messages, manage cryptocurrencies, send and receive cryptocurrencies, exchange with fiat, and make payments in a brick and mortar store.

Traditional SNS and messaging applications are run by operating companies, and services are provided largely for the purpose of growth and development of the operator. This means the purposes of the operating company and the users don’t necessarily align. The freedom enjoyed by users is restricted at the operator’s discretion. For example, the operator can view user information, such as the contents of messages sent and registration information, if they deem it necessary.

LABO Whitepaper -© 2018 LABO Corp. All Right Reserved. - -5

LABO Whitepaper Rev 1.4

We are here to question the status quo that is accepted by everyone, and offer a solution: the development of a decentralized platform.

The LABO token in LABO network is a modular utility token for increased activities in the LABO network. With LABO platform and token , users will have total freedom which was unattainable in Web2.0 era.

Such freedom translates into an array of things such as governance in LABO client, a curation function as social network, anonymous communication, and settlements. In other words, we would like to show user acquisition strategies for expansion of LABO network by introducing price-competing market which propose price two-way rather than solely by companies, such as Sticker market, and transfer capacity expansion function market for sake of user-friendliness.

To demonstrate our research results of user acquisition strategies we have devised for expansion of LABO network, at LABO project, LABO token is issued, and a subsequent token sale will be held. With this solution, centralized SNS and messaging applications can utilize distributed network technology to strive for a decentralized future.

We have the page, “Understanding LABO in 3 minutes”, which briefly summarize superiority of LABO, so we recommend you to read it. https://laboproj.io/wp-content/uploads/2017/12/LABO-in-3minute-1.pdf

Token Features

The LABO token in LABO network is a modular utility token for increased activities in the LABO network. With LABO token, users will have total freedom which was unattainable in Web2.0 era. The total freedom we mentioned in this case means an array of things such as governance in LABO client, curation function as social network, anonymous communication, and settlements.

Also we would like to demonstrate research results of user acquisition strategies for expansion of LABO network by introducing price-competing market which proposes two-way pricing rather than solely by companies, Sticker market, and transfer capacity expansion function market.The following is a list of LABO token feature (Including features implemented after approved ): ・Group chat ・Restricted participation to group chat ・Push notification ・Remittance in chat ・Remittance to address expressed in QR code ・High level encryption of communications ・Pre-approval of contacts

LABO Whitepaper -© 2018 LABO Corp. All Right Reserved. - -10

LABO Whitepaper Rev 1.4

Group chat feature will function with issuance of shared group chat ID.

All communications within group chat will be encrypted based on shared group chat ID, and a key specific to the group chat will be issued.

Even if an outsider eavesdropped into this chat log, decryption is not possible without the specific key owned solely by group administrator. Also, if group administrator had transferred the power to another member, this specific key will be changed.

Pre-approval of contact is expected to be used by celebrity figures of respective fields. If contact request was made by someone who you have not contacted in the past, the minimum LABO token required as deposit for new contacts can be set up. This is similar to follow request in modern SNS, and set amount of token will go to the recipient at the time of approval.

LABO Whitepaper Rev 1.4

What is Ethereum and ERC-20 Ethereum

An information exchange network requires a medium for it.

We considered the use of various distributed autonomous networks, and Ethereum was selected as the most appropriate after careful evaluation. This is because the Ethereum network is powered by self-executing functions of Smart Contract and has a track record of extensive Dapp developments, and our vision has a much higher possibility of being realized on it.

Smart Contract functions in Ethereum can be regarded as an automated execution of a contract on-line. In the real world, if creditor A wants to collect his credit from debtor B, the methods for execution available are either persuading debtor B to pay up, or get a hold of debtor B’s account information and resort to legal means of debt collection executed by the state. If, however, this contract was defined in Smart Contract which was registered on Ethereum network, this debt collection can be automated.

In the application, if the user wants to add push notification function offered company X, he/she can do so automatically without any contact with company X. Needless to mention, if company X’s fee doesn’t suit, company Y or Z can be selected. Actually, X, Y, and Z here represent nodes, not companies.

LABO Whitepaper -© 2018 LABO Corp. All Right Reserved. - -12

LABO Whitepaper Rev 1.4

The de facto standard is ERC20, which is for utilizing rich track records of DApp developments. The advantages of using ERC20 is largely that it’s already being used in various distributed network services using DApp and ERC20. Distributed storage service Swarm, Whisper which is for P2P communication, and TrustDavis for evaluation of reliability. Our LABO application utilizes these as well.

The reasons for utilizing de facto standard are such as it’s already being used for individual projects, and bugs and vulnerabilities are reported frequently and fixed in great numbers. We do not have the time for re-invention of wheels, as we are aiming to achieve release of product versions as quickly as we can.

LABO Whitepaper Rev 1.4

Governance

The major flaw in networks until Web 2.0 was ordinary users had no influence on the network as a whole. In order to use the service, he/she were required to accept the terms by the provider unconditionally as a matter of fact.

In the LABO network, although a user is required to accept our terms in the beginning, but after that he/she has direct influence over all decisions within the network, including method of software development. Tokens are used for decision making with regard to certain proposals, and as a result the direction of software development will be democratically determined. More specifically, LABO tokens are replicated every time certain decisions are made for creation of tokens pertaining to individual decisions.

At initial stage, said flow will be collaborative especially in software development, and LABO tokens are paid as rewards to anyone posting issues on public repository about LABO network on github specifically. At this stage, we have not been able to process all decisions regarding the software democratically, but in the future we will be paying attention to Dapp projects to automate all decisions about network.

LABO token smart contract on Ethereum network has been published on the github public repository in its entirety and can be confirmed by everyone. Included in it is token sale details written as code.

LABO Whitepaper Rev 1.4

LABO App images and features

In this chapter we take a closer look and introduce images and features of LABO application.

The above image represents messaging and wallet screen in LABO. In consideration of intuitive user operation, its UI is no different from traditional messaging apps. From the location of Ethereum icon within screen one can remit LABO token or ETH. The UI is currently wireframe stage and possibly subject to change after release of β version. Needless to say, after that, users will determine democratically based on Ethereum network with respect to the extent possible.

LABO Whitepaper -© 2018 LABO Corp. All Right Reserved. - -15

LABO Whitepaper Rev 1.4

LABO application also comes equipped with Ethereum wallet function. According to the development schedule, the wallet function will be ETH only until product version development, but including Bitcoin and other major coins will likely come as a result of user decisions.

Also in α version, only wallet managed on LABO application are implemented, but in the future, we would like to partner with companies with hardware wallet technology, and make use of hardware wallet that can be managed on smartphone if possible.

・Use case

Usually managed by walls on LABO app. (hot wallet), but by connecting hardware wallet to smartphone, another wallet tab will appear and can be managed in cold wallet.

LABO Whitepaper -© 2018 LABO Corp. All Right Reserved. - -16

LABO Whitepaper Rev 1.4

Security

Still, security is a big issue. We investigate vulnerabilities in each version of protocols and search closely for exploit, and writing modification program to absorb such behavior. In addition to these tasks, we need to consider security issues in development of our own application.

In LABO app. message encryption function is done using specific information provided by Ethereum network, but for content that require confidentiality, additional encryption are being evaluated currently. Taking ideas from Ethereum network’s plan to adopt PoS (proof of stake) in SERENITY, in LABO application also trusted third node is selected and given the role of Certificate Authority, which will make establishment of CA on blockchain possible. CA will still have the issue of trust (or why should we) theoretically, but PoS may improve it.

As for security, we will make careful observations as to which scheme is best for us to adopt by considering all of the following: direction of Ethereum itself and its development status, development status of Dapp like TrustDavis, and their stability and vulnerability, and how they affect operability. These decisions are also the part which will be decided by users in the future.
