SummaryEver since the introduction of Bitcoin as a crypto currency in early 2009, we have witnessed greatinterest in the usage of the technology. In a span of 8 years, we have seen an astronomical growthin the landscape, with close to a thousand different projects centering on the blockchain technology.
This rapid growth gave rise to the use of cryptocurrencies that are an alternate form of valuetransaction within the burgeoning blockchain community and which are fast spreading to
mainstream use.
In recent times, there have been many newly created projects in the blockchain space that arefocused on crypto-centric users, some of which are cutting edge and highly motivated to not only
succeed in the initial offerings, but scale as markets and economies transform over time. On thecontrary, most of the headlines by mainstream and legacy organizations/enterprises on the use ofblockchain solutions are no better than a simple proof of concept. The majority of these mainstream
initiatives even leverage on taglines such as “blockchain inspired” or “blockchain centered”
technologies, thus giving a new impetus and interest to their existing business.
The general notion is that cryptocurrencies are inherently volatile and this feature is here to stay. In
fact, volatility can sometimes be a strong selling point for cryptocurrencies, but that is also one of
the largest obstacles for real businesses to adopt them. And network fees always haunt us as wetry to implement public blockchains in legacy business practices such as trades, bookkeeping,guidelines, or compliance. The fees, per se, are not that they are expensive, but they become an
administrative nightmare as their users should not be bothered with having to deal with managing
their transaction fees.
As such, this rate of phenomenal growth has undoubtedly left many gaps that are yet to be fulfilled.
The existence of these gaps has resulted in a high barrier to entry for enterprises who have trouble
trying to bridge their islands of existence to the rest of the crypto and mainstream economies. We
are in a state of flux and solutions are needed to address these issues.
Tech Bureau Corp. is now carrying out a token sale exercise to crystalize an effort to offer a solution
to address the aforementioned problems.

COMSA Token Sale"COMSA" is derived from ”Computer” and 鎖 (Kusari/Sa): meaning "chain," combining to make"blockchain."
Before COMSA launches as a full-fledged service it will undergo an token sale exercise. The
cryptocurrency raised from the token sale will not only fund us to expand its reach in a rapidly
growing ICO market, but also to accelerate the growth of our existing core businesses, which are
the crypto exchange Zaif and the private blockchain product, Mijin. Both Zaif and Mijin are coreelements of the COMSA solution.
The token sale will be launched at 14:00 JST on October 2nd, 2017 and closes at 14:00 JST on

COMSA Whitepaper - © 2017 Tech Bureau Corp. All Rights Reserved. - 3 -​COMSA Whitepaper Rev1.3
November 6th, 2017. Below are the details of the token sale:
●

●

●

Token sale participants will receive 1 COMSA (Symbol: CMS) token per 1USD equivalent
contribution. No cap is set.
At the end of the token sale, based on the number of tokens issued for the participants, anequal number of CMS tokens will be issued and issuance will be locked. In other words,
100% more will be issued over the subscribed number.
Of this 100% more, 10% will be distributed as referral bonuses to token sale referrals.
40% will be distributed to the existing management team, stakeholders, developers,
employees, contractors, and COMSA ICO committee management. 50% will be retained byTech Bureau for future development, future distributions, marketing, partnerships,
compensations, and expansions.
As a result, 55% of the grand total will be distributed to the contributors.

Presale of CMS tokens with a 20% bonus will be available for participants who intend to contributeat least 100,000 USD equivalent of cryptocurrencies. Presale can be purchased with BTC, ETH or
XEM. Please contact COMSA management team at ​https://comsa.io/en/#contact
Also, following time bonus will be applied for token sale.
+14% Oct. 2nd. 14:00 – Oct. 4th. 14:00（JST）+10% Oct. 4th. 14:00 – Oct.11th. 14:00（JST）+5% Oct. 11th. 14:00 – Oct. 25th. 14:00（JST）

Token Functions and Benefits
COMSA is a platform gateway for the aforementioned variety of blockchains. . This platform canalso be used by companies that wish to carry out their ICOs. COMSA’s value proposition is its
infrastructure where it can offer these companies a complete ecosystem for their ICOs, which
includes the Zaif Exchange, multi-cryptocurrencies subscription, cross-platform integration and aready ICO asset creation through the use of the NEM and Ethereum public blockchains and mijin
private blockchain respectively.
As part of COMSA’s very own token sale, CMS holders who bought their CMS from COMSA’s token
sale exercise will get to enjoy a premium bonus of 5% for every CMS they use to participate in these
COMSA Whitepaper - © 2017 Tech Bureau Corp. All Rights Reserved. - 4 -​COMSA Whitepaper Rev1.3
future ICO campaigns on the COMSA platform. For example, if 100 CMS tokens are utilised topurchase a new ICO, the purchaser will be granted 105 of their chosen token, the 5 being a bonus
as opposed to a regular purchase without the CMS token.
As detailed later in this paper, we have managed to secure interests from a few successful
businesses to use the COMSA platform for their upcoming ICOs, which naturally, will create moredemand for the CMS tokens.

Community Vote
Although all ICO projects will be screened by Tech Bureau and the ICO Committee, there could still
be challenging projects that are potentially risky to token buyers. In such cases, COMSA will
escalate the projects to the community to vote.
CMS token holders will be eligible to vote for these ICO projects based on the number of tokens
they hold at a certain block height to determine whether it should go ICO with COMSA or not.
COMSA will create a contract on Ethereum blockchain to allow ETH:CMS holders to vote using
special voting tokens. Holders can send those tokens to specified addresses.
On the NEM blockchain, voting will be even easier. NEM’s open-source wallet software Nanowallet
now has an official voting module. We can allow NEM:CMS holders to vote directly from the wallet.

on the Zaif market from time to time. These revenues include:●●●

ICO consulting and service fees.
Conversion fees of COMSA CORE.
Mijin license fees and BaaS license fees.

Invitation-Only Pre-Sale of Future ICOs
As a privilege, CMS token holders will also be invited from time to time to invest in future ICO
projects which are only opened to invited participants and not for the public.

ICO Market and Industry
In June 2017, the total funds raised by ICOs exceeded the amount that blockchain startups hadraised from venture capital companies for the 12 months preceding it.
Since April 2017, the ICO market has been growing rapidly by more than 100% every month, and30 or more ICOs are being launched in July 2017.

COMSA Whitepaper - © 2017 Tech Bureau Corp. All Rights Reserved. - 6 -​COMSA Whitepaper Rev1.3

Source: ​https://www.coinschedule.com/stats.php

The total market cap of cryptocurrencies has risen close to 6 times in just 4 months from 20 billion
USD to 116 billion USD at its peak in June 2017. Contrast this with how it took the market 8 years
since the launch of Bitcoin to reach a market capitalization of 15 billion USD and it creates anincredibly positive outlook for the future of cryptocurrency.

COMSA Whitepaper - © 2017 Tech Bureau Corp. All Rights Reserved. - 7 -​COMSA Whitepaper Rev1.3

Source: ​http://coinmarketcap.com/charts/
We expect the total market cap to grow up to 1 trillion USD by the end of 2018, with the ICO market
growing to more than 5 billion USD by then.
COMSA’s goal is to target 100 million USD in 2018 with more than 20 ICO projects.

COMSA ICO Solution
COMSA is not just a cross-chain controller and router. It is also a conduit for future ICOs that want
to exist in the COMSA ecosystem. As part of the project, a COMSA team is now already in place toprovide companies with consultation, expertise and solutions to support their very own ICOs andimplement blockchain technology into their business practices, all at the same time, as a one stop
solution.

Given the pent up demand, the COMSA team is forging ahead to provide consultation to companies
wishing to go ICO while COMSA is building its platform. These early ICOs will be using the existing
infrastructure of COMSA, such as the Zaif exchange and its technical expertise to make use of theexisting independent blockchains of Ethereum, Bitcoin, and NEM to raise cryptocurrencies while
COMSA builds the integrated system for them to latch onto eventually. The initial services we will beoffering will include:
●
●
●
●
●
●
●

Business planning and service design utilizing blockchain technology, especially tokens.
Tokenizing mainstream assets into cyberspace assets.
Legal support for ICO and tokenization.
Creation of a multi-language whitepaper.
Token issuance and sale using a crowdsale platform
Providing a market on Zaif exchange.
Mijin private blockchain technology on the premises or on BaaS as internal ledgers.

COMSA Whitepaper - © 2017 Tech Bureau Corp. All Rights Reserved. - 8 -​COMSA Whitepaper Rev1.3●●●

Network fee delegation and fiat & crypto pegged tokens to allow existing business
transactions on NEM public blockchain in fiat currencies or major cryptocurrencies.
Smart signing contract development on the NEM blockchain.
Smart contract development on the Ethereum blockchain.

In the future, when the COMSA platform is completed, we will include the following offerings into
these ICO companies and new ICOs with the following value added services:●●

Integration with the COMSA CORE
Integration with the COMSA HUB to connect and peg between the mijin private blockchain
and public ones.

COMSA and Other Upcoming ICO Projects in 2017
Instead of future decentralized apps, COMSA focuses on existing mainstream businesses to launch
their ICOs. This method of ICO not only brings legitimacy to ICOs but also introduces mainstream
businesses to leverage on the cost-effective, safe, and secure blockchain technology to improvetheir businesses and position them to be more efficient.
Starting with COMSA itself as the first ICO, we will have the following ICOs scheduled immediately
after, later in the year.
1. Premium Water Holdings Inc (2588.T)
Few more ICO projects are to be announced in Oct. and Nov. 2017.
The above are successful businesses in the off-chain world from Japan, but the COMSA solution is
not limited to just Japanese businesses, we have also started inviting businesses globally for ICOs.
Details of each such ICO shall be revealed and disclosed as more ICO projects are to beannounced, but suffice it to say that the response so far has been great.
The above ICO projects will proceed ahead without our core platform offerings but will be integrated
when we are ready to include the COMSA platform solution.

What is COMSACOMSA aims to solve the problem of bridging enterprises and their existing businesses to publicblockchains. COMSA is proposing to bridge NEM, Ethereum and the Bitcoin public networks
together with the mijin private blockchains that enterprises will be using. The idea is to bridge theseenterprises and cryptocurrency owners so as to provide an avenue for cryptocurrency owners tospend while enterprises can have an immediate and extended market to sell their products andservices and continue to develop their blockchain solutions to cater for mainstream users.
Additionally, this symbiosis also allows both sides of the crypto and mainstream economies to cometogether on a common ground, promoting the proliferation of the crypto economy into themainstream, vice-versa, and therefore, help in the widespread acceptance of crypto currencies.

COMSA Whitepaper - © 2017 Tech Bureau Corp. All Rights Reserved. - 9 -​COMSA Whitepaper Rev1.3
COMSA, a project to be undertaken by Tech Bureau Corp, will carry out an ICO exercise and issue
ICO tokens. This project will enable centralized businesses the ability to utilize blockchain
technology and prepare them for the eventuality of being able to face a more decentralized world.

No matter what protocol one is using, whether it is Bitcoin, Ethereum or the NEM protocol,
enterprises can now choose the right technology to suit their requirements. Additionally, COMSA
enables organizations that have already previously embarked on any of the protocols to stillleverage additional services and to extend its reach to the other ecosystems offered by COMSA.
This powerful utility using the COMSA platform, in combination with Zaif Exchange makes thisoffering a holistic enterprise class solution never seen before.
COMSA allows enterprises to remodel and monetize their organization as a private token economy
on the blockchain using the strong NEM protocol, as well as the ability to utilize powerful smart
contracts of Ethereum to begin building decentralized applications. By leveraging on COMSA, thedeployment and implementation of a blockchain will be much easier and faster than ever before, as
well as giving more breadth to the enterprise.
The NEM protocol using the mijin engine not only helps enable the business of an organization thatuses it, but it also provides the bridging of existing monetary values used in trades (i.e. fiat
currencies, major cryptocurrencies, etc.) onto the NEM ecosystem and Ethereum decentralized
applications. By consolidating these processes, an organization can begin implementing a
blockchain along with existing compliances and guidelines without affecting or disrupting its current
business practices. Customers can now leverage on the blockchain in their preferred currency.
Tech Bureau’s powerful private blockchain solution, mijin, also becomes a hub between adecentralized and a centralized economy. By pegging tokens between internal private and external
public ledgers, businesses can build a high-throughput blockchain record of transactions. This not
only allows organizations to obtain compelling benefits from the blockchain but also leverages on
the resources and advantages from within these organizations.

In conjunction with the Zaif exchange, which serves as a centralized trust-cum-exchange, that shallbe approved by the regulators, FSA of Japan, COMSA offers an unparalleled service that allows acryptocurrency (e.g., Bitcoin) to flow into the various networks and transact as if it is a coin in that
network. What it essentially means is that a cryptocurrency from another blockchain can betransacted in the NEM blockchain as an asset, and with this asset being backed by Zaif as thetrust-exchange. It can also be traded in the Zaif exchange as if it is a NEM or Ethereum asset.
Additionally, the same cryptocurrency can flow into the private mijin network, into the enterpriseservices and get traded as if it is a cryptocurrency in that ecosystem. In other words, fiat-backed andcryptocurrency-backed tokens - from outside the native blockchain - can be traded, interchain,
between NEM and Ethereum. As an example, one can virtually swap Bitcoin and USD on the NEM
or Ethereum blockchains and can even forget about network fees in some cases as describedabove. COMSA brings cross fungibility of coins in the networks it serves.
This is all made possible by utilizing the new Japanese crypto exchange regulations enforced with astrong segregation fund clause – the mandatory “trust” requirement.
By pegging tokens among NEM, Ethereum, and mijin private blockchains, the COMSA solution
becomes a practical “catalyst” between centralized businesses and decentralized blockchains. In
addition, the offering helps contribute to the growth of the entire blockchain ecosystems in Bitcoin,
NEM, and Ethereum.
In summary, the COMSA solution provides the following:
1.
2.
3.
4.
5.
6.

Hybrid token issuance pegged between NEM and Ethereum blockchains.
ICO solution and support using the above.
Crypto pegged tokens on NEM and Ethereum (BTC, ETH, and XEM)
Fiat currency pegged tokens on NEM and Ethereum. (JPYZ, Tether, etc.)
High-throughput private blockchain mijin for the internal token ledger.
Crypto exchange Zaif to guarantee listings of tokens and to insure pegged tokens.

The COMSA current strategy is to emphasize on bringing centralized businesses together, enhancethese ecosystems with elements of decentralization, and then when the technology matures,
upgrade them into additional decentralized business models. Accordingly, our policy now is toensure that we are “as solid, as trustful, and as auditable as possible” before we emerge to be more
decentralized as technologies mature. Tech Bureau recognizes how the future will be in adecentralized environment and therefore is able to bring this wealth of experience to help shapemainstream businesses in adopting and embracing blockchain technology.
With this method of solution using both private and public blockchains, COMSA works as a core
controller, a hub, and a catalyst. We believe COMSA can contribute to the growth of the greater
blockchain ecosystem including Bitcoin, NEM, and Ethereum by bringing more assets frommainstream into the blockchain space.

COMSA CORE
We have mentioned the COMSA CORE and COMSA HUB in the description of our project. Here,
we shall define the COMSA CORE. COMSA CORE is the most essential part of our COMSA
platform. COMSA CORE pegs and controls tokens between the NEM, Bitcoin, and Ethereum

COMSA Whitepaper - © 2017 Tech Bureau Corp. All Rights Reserved. - 11 -​COMSA Whitepaper Rev1.3
blockchains as an independent service of Tech Bureau. It converts value among cryptocurrencies
into pegged tokens with the total volume controlled.
COMSA CORE monitors incoming transfers of cryptocurrencies or tokens into a COMSA masteraccount with the final destination details embedded in them. It then locks or burns that amount in the
COMSA master account. At the same time, it also unlocks or issues equivalent cryptocurrencies or
tokens on the corresponding blockchain and sends them to their final destination account.

COMSA CORE = Conversion Network
COMSA CORE consists of a controlling application, an oracle application and 2 mijin private
blockchain networks built on 9 cloud server machines, which are distributed globally to achievezero-downtime token conversion service.

COMSA CORE is a hidden and private network, except for one auditable API node. 9 nodes will betotally hidden from the public and work as a conversion network independent from publicblockchains.

COMSA Whitepaper - © 2017 Tech Bureau Corp. All Rights Reserved. - 12 -​COMSA Whitepaper Rev1.3

Zero-Downtime COMSA CORE
There will be 9 servers built in 9 regions operated by 4 cloud vendors to achieve zero-downtime
service. We are currently planning a 50 tx/s capacity (4.32 million tx/day) with 8GB of RAM and 8
core CPU on each node. So far we have built dozens of zero-downtime ledgers with our clientsusing mijin for the last 18 months and also expect no down time with the COMSA CORE. The
maximum throughput capacity stated above is for the internal ledgers only, with the performance of
token conversion among public blockchains dependent upon the limitation of each blockchain.

Oracle (Monitor)
Each server works as an oracle to observe Bitcoin, NEM and Ethereum nodes for incomingtransactions. The oracle analyzes the confidence level and number of confirmations for eachconversion for authorizing any outgoing transactions.

Multi-sig Authenticator
Each server operates as a multi-sig signatory to sign all outgoing cryptocurrency or token
transactions upon conversion. COMSA will reach consensus with X out of 9 nodes being used as
signatories.

COMSA CONTROLLER
The COMSA CONTROLLER consists of 9 nodes that will control the total volume of pegged tokens
among multiple blockchains. The function of the COMSA CONTROLLER includes:●●

Locking and unlocking of cryptocurrencies.
Issuance and burning of pegged tokens.

Auditable API
One of the mijin nodes will be duplicated and exposed as a publicly auditable API. This special
node will not have any significant impact on the security of the private blockchain network and has
no power to initiate, authorize or confirm transactions, thereby avoiding any unauthorized requests
or confirmations.
Periodic Block hashes of the mijin ledger will also be anchored to the NEM and/or Bitcoin blockchain
for proof of non-manipulation.
One of the main innovations of the blockchain is its auditability and as a direct result of that, a user’s
ability to trust the ledger’s history. The main criticism often pointed at permissioned chains is thatthey can be easily tampered with, changed, or edited making their ledger untrustable. By anchoring
the block headers of COMSA into the Bitcoin and NEM public chains, a full and transparent audit
can take place allowing users to know the COMSA ledger has not been compromised up to thepoint that an attacker would have had to unwind and undo both the NEM and Bitcoin public chains
to have had achieved their task.

Two-Layer Ledger
As mentioned above, the COMSA CORE shall be 9 servers running 2 mijin networks..

COMSA Whitepaper - © 2017 Tech Bureau Corp. All Rights Reserved. - 13 -​COMSA Whitepaper Rev1.3

The first ledger is dedicated for the conversion between native cryptocurrencies and pegged tokens.
And the second one is for the conversion among pegged tokens.
1. Native cryptocurrency ⇔ Pegged Token
2. Pegged Token ⇔ Pegged Token

The Advantages of Centralization
In the worst case scenario of a system failure, the total volume of pegged tokens might go offbalance. A two-layer ledger will minimize the risk of inconsistency as a result of the failure. For
conversions involving native cryptocurrencies, there is no way of rolling back the public blockchains.
But, we can halt the operation of the COMSA CORE as a circuit breaker. We can then do areconciliation of the discrepancy and adjust the balances accordingly.
In the event of a public blockchain facing a hard fork, as a centralized service, and like existing
crypto exchanges, COMSA can halt the conversion service and decide which fork to adopt as alegitimate chain. Depending on the business rules, we could also adopt and accept both forks as 2
separate blockchains.
Those incidents are technically hard for decentralized applications to handle. COMSA CORE, as acentralized and independent service, will prioritize the benefit and experience of both thebusinesses and users.

COMSA HUBCOMSA HUB is a software for licensed holders of mijin private blockchains to control token
balances between master public blockchain accounts and internal private ledgers.
COMSA HUB can be installed as a part of any mijin private blockchain network as an independent
service controlled by the business using it. Compared to COMSA CORE that handles pegging
among public blockchains as a service provided by Tech Bureau, COMSA HUB handles pegging
between the company’s assets on public blockchains and the internal ledger on the mijin private
blockchain inside the company’s network.

COMSA Whitepaper - © 2017 Tech Bureau Corp. All Rights Reserved. - 14 -​COMSA Whitepaper Rev1.3

COMSA HUB monitors incoming transfers of cryptocurrencies or tokens to the company’s publicmaster account with final destinations included in a message. It locks that amount in the company’s
public master account. Subsequently, it creates the equivalent private tokens inside the company’s
mijin private blockchain and sends it to the corresponding account. When it detects an outgoingtransaction by receiving an incoming transfer to the company’s private master account with the finaldestinations included in the message, COMSA HUB burns these tokens on the mijin private
blockchain and unlocks the cryptocurrency or tokens on the public blockchain and sends them tothe corresponding address.

Fiat Pegged Tokens
Fiat-pegged cryptocurrencies are set to emerge and grow rapidly in the crypto landscape. A case inpoint is Tether, a USD pegged cryptocurrency, which grew from a market cap of about $55m in April
to about $290m in July, representing a phenomenal growth of about 527%!
A couple of projects such as BitUSD or NuBits have attempted to peg the USD to their crypto
currency in a decentralized and trustless manner using their proprietary algorithms, but these havefailed miserably.
Tether’s approach is a centralized and privately owned service operated by a Taiwanese
corporation, and is a futures contract derivative, backed by the USD. This method of pegging to the
USD is a more effective way of ensuring that the peg is true to its value. More proof to it being aviable model is the that it is still being circulated, even after the halt of their USD account at theWells Fargo bank.

COMSA Whitepaper - © 2017 Tech Bureau Corp. All Rights Reserved. - 15 -

​COMSA Whitepaper Rev1.3

Source: ​http://coinmarketcap.com/assets/tether/

Tether(Symbol: USDT) is not only treated as if it is a standard USD pegged cryptocurrency atseveral major exchanges such as Bitfinex and Poloniex, it has also been proven that users prefer astable pegged currency even if it is totally centralized.
The Japanese Blockchain Collaborative Consortium - BCCC, which Tech Bureau sits on its board,
also has started a social experiment of a JPY pegged token, Zen (Symbol:JPYZ). JPYZ is currently
a private token issued on the private Ethereum network as an ERC-20 token, and can be traded
only among BCCC members. Participants were invited from BCCC’s 150+ corporate members, andafter 6 to 9 months of private tests, the token will be converted into a public ERC-20 token.
Using COMSA CORE, COMSA will issue pegged tokens for those major fiat pegged
cryptocurrencies, and allow people to trade or contract in fiat currency virtually on the NEM and
Ethereum blockchains.

Cryptocurrency Pegged Tokens
With the same logic as fiat pegged tokens, COMSA will also issue crypto pegged tokens on the
NEM and Ethereum blockchains such as NEM:BTC or ETH:BTC.

Business Transactions on Public Blockchains
In a combination of fiat pegged tokens and crypto pegged tokens, COMSA is now bringing practicalbusiness transactions onto public blockchains. People can use fiat or crypto equivalent values on
public blockchain for smart signing contracts on NEM or smart contracts on Ethereum.

One-time Use Multi-Party Smart Contracts
Mijin’s upcoming new Catapult engine has a unique feature called “aggregate transactions”. An“aggregate transaction” basically combines multiple transactions as a set, and allows them to

COMSA Whitepaper - © 2017 Tech Bureau Corp. All Rights Reserved. - 16 -

​COMSA Whitepaper Rev1.3
simultaneously transact upon the completion of a multi-sig sign-off from all the parties involved.
Note this is not accomplished via a multisig contract, it is an atomic swap, as long as the final
balances are valid. This can be thought of as a one-time use multiparty smart contract that is
natively supported by the Catapult Core. This new way of thinking about and executing contracts
works via API calls and takes away the burden and risk of having to write a complicated smart
contract designed for long term and repetitive use. Additionally, the one-time use contract will either
execute or not execute as designed depending available balances. This limits the losses in contrast
to longer term smart contracts that were written incorrectly and and are subject to repeatedly being
attacked.

Network Fee Delegation
For an example of an aggregate transaction, let’s say Alice wants to sell 1 NEM:BTC for 300,000
NEM:JPYZ, and Bob wants vice versa, but they do not have any XEM. Now, Alice can request Zaif
exchange for network transaction fee, by paying 0.00001 BTC. When all 3 parties sign the request,
Zaif exchange pays 1 XEM for the network fee and receive 0.00001 BTC for that service. At thesame time, Alice and Bob can swap those values without buying any XEM.

This new concept allows people to carry out most of the business transactions on the NEM publicblockchain without even realizing the need to use the XEM native currency for the network fee. We
believe this will popularize trustless transactions in native currencies as it eliminates the need fortrusted 3rd party such as escrow services.
This new feature will be introduced in the new Catapult version of the mijin private blockchain
solution first, and subsequently will be implemented in the NEM public blockchain in 2018.

Demand for Centralized Service
As mentioned above, even with the long term risk of liquidation, Tether is growing rapidly as themost popular fiat pegged cryptocurrency. At the same time, instant exchange services such as
Shapeshift and Changelly, also centralized services, are very popular and convenient among manyusers. The risk of using these services is minimum and limited to the time of a conversion and aconfirmation in the destination blockchain. An asset goes through a centralized service for that
instant of time, but once it is received at the destination, the asset is secured. While the blockchain

COMSA Whitepaper - © 2017 Tech Bureau Corp. All Rights Reserved. - 17 -​COMSA Whitepaper Rev1.3
was founded with the understanding that decentralization is a fundamental tenant, it is undeniable
that centralized services are and will continue to play very important roles for the crypto industry.
COMSA uses blockchain technology to provide for these services. With COMSA, except for the fiat
pegged tokens, people can minimize the risk of loss by disposing their assets instantly at the native
blockchain level. If some exchanges guarantee the disposal of those fiat pegged currencies, therisk will be limited to that time frame. With COMSA, depending on the risk capacity, one can turn
fiat currencies or cryptocurrencies into tokens first using the blockchain. We believe the benefits ofthese blockchains will override the risk of loss very easily, vis-à-vis the likes of Shapeshift or
Changelly.

Japanese Regulation
On April 1st, 2017, a new law was passed and enforced to regulate crypto exchanges in Japan.
Existing crypto exchanges have been given a 6-month window to register themselves with the FSA,
i.e., by Oct. 1st, 2017. Tech Bureau’s, Zaif, submitted its application to FSA for approval as one of
the largest crypto exchanges in Japan. Approval is expected to be given by Oct. 1st, 2017.
This new Japanese regulation will enforce the need to have a proper audit of all transactions as well
as requiring exchanges to have proper segregation of funds held in trust for both fiat currencies andcryptocurrencies. As a licensed and registered Japanese exchange, Zaif, will be able to utilize
these segregation requirements of the regulation to provide better credibility than exchanges inother places.
All the funds received at Zaif exchange on behalf of COMSA for crypto pegged tokens and fiat
pegged tokens, will be segregated as required by law.

NEM is one of the largest blockchain/cryptocurrency projects in the world. Instead of a programing
language based contract, NEM emphasizes on its Smart Asset Model and signature based “Smart
Signing Contracts” available out-of-the-box via APIs. Additionally, it can utilise an off-chain smart
contract to drive its transaction outcomes onto the blockchain.
The NEM blockchain solution allows the creation of uniquely defined token assets in a tree-likestructure, using Namespaces and Sub-Namespaces.
With the combination of both the On-chain Smart Asset Modeling, off-chain smart contracts, andSmart Signing Contracts, the powerful NEM protocol can substantially decrease the application
development time by 50%.
The native cryptocurrency of NEM is called “XEM”, and it has grown its market cap by more than
100,000% in 2 years to be one of the largest cryptocurrencies in the world.

COMSA FAQs
What does “COMSA” stand for?
We simply translated “Chain” of “Computer Chain” into Japanese kanji “鎖 (Kusari / Sa)” andcreated a new word “Com Sa”. It is also pronounced in the same way as French phrase “Commeça”, which means “like this” in English. We would like to lead the market to show how real world
businesses can utilize blockchain technology “like this”.

APPENDIX 1 - Use Cases
Use Case - Talent Trading Cards Let’s say some talent management business “A” is to issue trading cards for dozens of talents. “A”
issues token asset for each talent on the NEM blockchain and provides an app for users to make acollection of these cards.
COMSA first supports “A” to go ICO for “A token” as its central currency. “A” raises a certain
amount of funds to develop trading card services and apps.
“A” creates 10,000 trading cards per each talent as token assets on NEM blockchain. Users have toobtain “A token” first to buy any trading cards from “A” or in the exchange market. Trading cards get
added into the app as users collect them one by one. These cards can be swapped or transferred
directly among users, or traded at Zaif exchange.
Users send those cards to the game app to play it, and playing rules are written in public smart
contracts on Ethereum network. For token transfer between apps, COMSA CORE converts NEM
assets into Ethereum tokens. All the fees will be charged to users by “A” in “A token” to cover
network fees. The game app also allows users to win trading cards from other users which
automatically gets transferred into their app. These trading will be converted via COMSA CORE.

Instead of managing the inventory of trading cards using raw secret keys or some token devices, “A”
builds an inventory management system with the mijin private ledger. Any transfer of newly issued
tokens can be authorized only by a multi-sig sign-off between designated operators and the
management team.
Asset information will be disclosed openly, and developers can create their own apps or web
services to handle trading cards. “A” withholds all the copyrights of trading card images and canprotect them from unauthorized commercial usages.

Use Case - VR World CurrencyVirtual Reality is a novelty and is becoming a craze. At the same time, it is undergoing a paradigm
shift in its use and sophistication. New virtual reality games will need to have a dedicated currency
for each game in the virtual economy. The Linden dollar for second life is one such example.
A Blockchain solution, especially if it is running on a private network where there is more control andflexibility, is very suitable for VR games, vis-à-vis public chains that may have other issues runningit.
COMSA is a well suited solution where currency tokens in the public blockchain can be integrated
into the internal and private blockchain of the VR game using the mijin private blockchain. These
ledgers will be synchronized and balanced using the COMSA HUB.
This tightly coupled integration allows users to send and receive tokens from outside the VR realm
to a specific user in the VR realm that is powered by the mijin private blockchain. Further, thecurrency can be in any denomination such as ICO issuer’s token, Bitcoin, XEM, Ether, or even fiat
currency pegged tokens.
This method of VR balance management now uses the blockchain to manage balances instead of alegacy database. Essentially the blockchain solution makes this more secure and efficient. TheCOMSA offering also allows token transfers to be ubiquitous in a few more public blockchains, thus
covering a wide market.
A private blockchain enables a much higher throughput in excess of one thousand transactions per
second, hence enabling micro transactions in real-time in the VR environment. This allows for VR
games to be run on a blockchain, while at the same time, allows for public blockchain tokens to beuseable in the VR platform.
VR token balance cannot be changed and can easily be audited using the APIs in the mijin private
blockchain. Hence fraud, and manipulation of token balances is full-proof in the blockchain
environment.
This highly secure environment prevents a lot of fraud from happening and also allows for user
peace of mind that they can send money or cryptocurrencies into the VR environment and be surethat their token balances will not be changed or manipulated.

In the above example, COMSA bridges Alice’s NEM:USD (public blockchain) to Bob by way ofsending an equivalent pegged amount of mijin.001:USD to Bob in the VR private chain, all madepossible using the COMSA solution.

Use Case - IoT Authentication & Ledger In a IoT era, we have to manage millions of devices and million account balances for monetary
values exchanged among them.
Blockchain technology can be the best answer for IoT to manage them, and COMSA solution would
be most suitable.
Capacity problem always haunts us when talking about the public blockchain. There are several
developing technologies such as sidechain or lightning network but COMSA proposes a realistic
solution utilizing private blockchain networks instead of an add-on layer technology.
An address generated by a device can be used among multiple mijin networks with the same
address. COMSA HUB lets multiple mijin networks talk to each other to sync and peg tokens, whileat the same time its balance is kept consistent among these mjin networks and even on publicblockchains such as Bitcoin, NEM, or Ethereum.
Any device can be authenticated using a multi-sig request on a private blockchains, that can handle
high throughput transactions.
This allows devices to have their own monetary balances settled as micro transactions for theirmicro jobs they have done, and at a high throughput.
The ledger itself can reside inside or outside of devices. Without compromising the security, mijin
let these devices interact with multiple private blockchains on the Internet.

COMSA Whitepaper - © 2017 Tech Bureau Corp. All Rights Reserved. - 26 -​COMSA Whitepaper Rev1.3

With COMSA, now those devices can handle fiat pegged tokens or cryptocurrency pegged tokens
directly. The owner of devices can control who can transfer the balance in the devices and towhere, and can even deactivate them by removing its key from the device in case the device goesout of control. All these authentication and controls can be done using the native NEM protocol in a
public blockchain or mijin private blockchain.
These mijin networks not only can handle value or money transfers, but they can also encrypted t
messages embedded on transactions. For example, one can send an order to her car to update its
firmware via Over-the-air, that can be opened only by the car itself and authorized by a multi-sig. All
these messages or requests can be sent via the Internet instead of VPN.
Controlling IoT devices, and managing their ledgers are easier than ever with COMSA solution.
