1. Summary

A cryptocurrency is a digital asset designed to work as a medium of exchange that uses cryptography to secure its transactions, to control the creation of additional units, and to verify the transfer of assets.

Cryptocurrencies are a type of digital currencies, alternative currenciesand virtual currencies.

Cryptocurrencies use decentralized control as opposed to centralized electronicmoney and central banking systems.

The decentralized control of each cryptocurrency works through a blockchainwhich is a public transaction database, functioning as a distributed ledger. (Wikipedia)

The blockchain was first embodied in a 2008 paper by SatoshI Nakamoto and was implemented as a key technology for BITCOIN. It uses blockchain technology as a public transaction ledger for publicly recording virtual currencytransfer information between traders.

A blockchain is a system that collects data over a certain period of time, creates data values by blocking them, and compares and validates blocks with encryptedhash values to store them on a recorded distributed server.

The advantage of this technology is that it can be protected and maintained very securely by sharing and storing the same data in P2P fashion.

Security, which makes transactions safer through the process of sharing and checking the entire transaction books of all dealers, is now a key topic in thefourth industrial revolution.

As a core technology in the fourth industry and a high level of confidence insafety, users are exploding, and the concern is that the block chain will

become overburdened.

Now is the time when traditional block chain technology needs to be constantlyevolving and the concept and structure to expand its functional elements.

1. Summary

We're at the point where everyone can run their factory production lines athome with a click and sell their products to consumers around the world.

In this era when all ideas are connected to profits, the technology of the blockchain will lead the way in the fourth industrial revolution.

According to Jan Lansky, a cryptocurrency is a system that meets all of the

following six conditions:

• The system does not require a central authority, distributed achieve consensus on its state.

• The system keeps an overview of cryptocurrency units and their ownership.

• The system defines whether new cryptocurrency units can be created. If new cryptocurrency units can be created, the system defines the circumstances of their origin and how to determine the ownership of these new units.

• Ownership of cryptocurrency units can be proved exclusively cryptographically.

• The system allows transactions to be performed in which ownership of the cryptographic units is changed. A transaction statement can only be issued by an entity proving the current ownership of these units.

• If two different instructions for changing the ownership of the same cryptographic units are simultaneously entered, the system performs at most one of them.

But the definition should be updated along with the recent outputs from the developers and ventures who voluntarily devote and/or contribute to the advancement of the cryptocurrency industry.

We are now facing some but big problems to be solved for the expansion of the cryptocurrency Industry, such as, Instability of the Value, Waste of Energy & Resources and so on.

◆ It is Miner-less Cryptocurrency◆ It is Decentralized but Controlled Cryptocurrency◆ It is started with a community which has tens of thousands potential users

Cryptocurrency Now

Cryptocurrencies are used primarily outside existing banking and governmental institutions and are exchanged over the Internet. While these alternative, decentralized modes of exchange are in the early stages of development, they have the unique potential to challenge existing systems of currency and payments. As of December, 2017 total market capitalization of cryptocurrencies is bigger than 600 billion USD and record high daily volume is larger than 500 billion USD. (by Wikipedia)

As of February 2018, there were over 1,500 and growing digital currencies in existence.

2. Problem & Solution

Facing problems with current block chain

Among the pros & cons and criticism, the major issues would be as follows;• High fees and long transaction times• Price fluctuation and user’s distorted expectation• Waste of Energy and Money: Electricity and some specific machine or parts

When there is an incentive to spend incredible amounts of energy to send transactions (especially microtransactions), we may say it is an inefficient, unsustainable system that is difficult to fix. As well as;• Payment of illegal transactions, creation of slush funds, and tax evasion• The responsible location is unclear in case of problems• Not enough compared to actual transaction size that can be paid and

processed• Ensuring complete anonymity may be difficult and re-installed by association• There is usually no solution for personal key hacking or loss• Storing global data in one block makes it difficult to process in real time and

large capacity

Our solution• Providing diverse services to the civil society in the most efficient and

personalized way• Ensuring the openness and opportunity for joint innovation to prevent the

concentration of values and power in the minority• As other centralized systems are provided, distributed security systems

eliminate threats such as cyber terrorism• Vital system for more stable and high value realization in this era of the Fourth

Industrial Revolution

2. Problem & Solution

We believe the “Miner-less” and the “Self-Governance” are the keys.All the economic and environmental concerns are associated with mining activity for rewards. We, therefore, would like to mainly take advantage of “Minerless” feature in TUC.

Unlike conventional blockchains, some directed acyclic graph cryptocurrencies utilize a pay-it-forward system, whereby each account performs minimally heavy computations on two previous transactions to verify. Others utilize a block-lattice structure whereby each individual account has its own blockchain. With each account controlling its own transactions, no traditional proof-of-work mining is required, allowing for free, instantaneous transactions.

In order to send transactions over a network, the user must perform a certain level of computations on two previous transactions in the network. These computations take, on the order of, a few seconds to a few minutes, depending on the power of GPU (or something compatible) and your luck.

Once the one successfully perform the proof of work required, the one’s bundle of data gets broadcasted over the network, where it sits waiting to be confirmed by future transactions. This is a pay-it-forward kind of system. Once the transaction gets enough confirmations from other peoples’ transactions, the transaction will be deemed fully confirmed. In theory, the more transactions that occur over the network, the faster your transactions get confirmed.

There are various "miner-less" cryptocurrencies already undergoing active development, including us.

In addition, the TUC is going to be “Decentralized but Controlled” cryptocurrency. We will discuss about them in detail later in the related chapter.

3. TUC & its Vision

What is TUC?

TUC is a peer-to-peer Internet currency that enables instant, near-zero cost payments to anyone in the world. TUC is an open source, global payment network that is fully decentralized without any central authorities. Mathematics secures the network and empowers individuals to control their own finances. TUC will feature faster transaction confirmation times and improved storage efficiency than the leading math-based, mining cryptocurrencies.

Vision of TUC

TUC is created to serve the U-Mind Like-Minded Community for global everyday usage. The TUC Technology Group is introducing TUC in alliance with the U-Mind Like-Minded Community (U-Mind Space) of U-Mind Space, Inc - a U.S. OTC market listed corporation. U-Mind Space is a membership on-line/off-line marketplace & community based on their own artificial Intelligence and robust applications on both desktop and mobile environment.By the strategic alliance, TUC is a cryptocurrency actually backed up by a community which has a platform that makes it spendable in the marketplace and community. It means it has a ‘ready-to-use’ member group in the U-Mind Space community, so that, TUC will take a lot less time to be a major cryptocurrency. TUC will keep and further elaborate the Good’s as a cryptocurrency, such as, border-free, less cost & easy to transfer, high level of privacy. And, TUC will diminish or remove the Bad’s, as mentioned above.Our most prominent milestone has been the establishment of a global method of banking that is accessible around the world for users to have the capacity to spend & store cryptocurrencies.

7

With the benefits from the community, such as, reward mileages, affiliated local shops and much more to be introduced, the TUC use population will be expanded rapidly. TUC will satisfy common users, both seller & buyer, who are usually reluctant to use Crypto-currency in the everyday life, such as, shopping, traveling and so on.

Different from the other altcoins which fluctuate in value, TUC will provide more sustainability in everyday usage. By the community governance through the PORTEM protocol and platform, the value of the TUC will be getting stronger in a stable manner. The outstanding volume and price will be governed by the community council self-governance to maintain sound and reasonable status of the currency.

The higher the volume of transactions in the TUC platform, the higher the potential market value of the TUC itself. Remember TUC is backed up by U-Mind Like-Minded Community.

The TUC is the Community-Oriented-Cryptocurrency.

U-mind Stores (Affiliated Local Shops)

Our Integrated U-Mind Mobile application will let you know if there is any affiliated store around you. You can find the location of the shop, the business hours, and the description of business through the map view and search. With your participation to use the local shops, we can all be in Win-Win situation ,including the store, the finder, the member and the company.

If you press the payment button of the store shown in the integrated app and enter the used amount, the payment will be completed with the confirmation by the shop owner. The shop owner would offer 5% ~ 20% of the price for our member’s sake as Point-Rewards; 50% of the amount goes to buyer, 15% to the sponsor, 5% to the sponsor’s upline, 10% to the store finder, 20% to the company. It is a service to build U-Mind Community together by helping each other and growing together.

DEN

"DEN" is defined in the dictionary as following. A cave where wildlife live, a small room or place where you can personally concentrate, a room where you can relax, and a hideout.The reason we named the so-called cafe-like service as DEN is that we hope a DEN would be a virtual space where members can enjoy, rest and relax with the Like-Minded people of their own.Thanks to the U-Mind AI, a DEN will be continuously recommended potential members with Like-Mindedness to the DEN. DEN's leader (boss) can send an invitation to the member, AI recommended, and the member can join the DEN by accepting the invitation.

5. PORTEM

PORTEM is a TUC’s unique protocol suite designed and to be developed to simplify governance through infrastructure modules that defines basic rules for specific types of units. The protocol, along with the PORTEM platform, allows effective unit for all matters surrounding the voting activities. With PORTEM, the creation and usage of community governance structure can be facilitated by the tools provided. Through the protocol, complexities of legacy governance systems can be simplified and implemented on the blockchain. The protocol also incentivizesthe third party developers to build functional extensions for the base protocol.

The protocol encompasses the necessary building blocks and toolset to build and design decision-making structures onBlockchain. The PORTEM platform is both user and administrator-oriented, and is the core for all decision execution.

The PORTEM Protocol providesunits with an efficient set of tools for creating a concrete set of governance structures. By providing users with an array of modules--types of governance models created by developers on its open platform--units of any size are enabled to control how they are governed.

Putting governance on the blockchain, through an open standard is beneficial in avariety of ways. Having a collaborative and open protocol ensures a lower risk profile and tightened security of the code as open standards develop over time.

Along with more simple governance, thePORTEM Protocol makes flexibility and modularity of a unit easier. Units can choose to update various components offered by the platform.

PORTEM Platform The Platform is the main interface for units, voters, and leaders. The design is intended to be intuitive, exhaustive, and simple. We believe that executing decision-making and voting should be as convenient as sending a text. The Platform will be both administrator and user-oriented, allowing units to deploy preferred methods of governance for their members, and for members to easily interface withagenda and voting functions.

5. PORTEM

Units – CommunitiesThere are many like-minded communities in the U-Mind Space. Some of them are bigger than the others, some of them are more active than the others. All the unit participation will be rated and rewarded by holistic review mechanism.

Voters – CitizensVoters are the members of TUC ecosystem, citizens of the nation.Voters exercising their wills through PORTEM, either with their vote or through the delegation of their vote, interact with an easy-to-use system and UI that prompts and supports their decision-making. All the individual participation will be rated and rewarded by holistic review mechanism, also.

Leaders - OrganizersLeaders are the ones who create units and/or agenda. They are community builders by contributing to shape the TUC community. Leaders propose to set the agenda and their agenda will be conveniently presented to voters. If agenda are simply presented to the voters and they are prompted in an efficient way, then democratic“decentralized but controlled” decision making processes can be accomplished more dynamically, quickly, and effectively.

Community Council – “the decentralized but controlled cryptocurrency”Decentralized cryptocurrency is produced by the entire cryptocurrency system collectively, at a rate which is defined when the system is created and which is publicly known. In centralized banking and economic systems such as the FederalReserve System, corporate boards or governments control the supply of currency by printing units of fiat money or demanding additions to digital banking ledgers. By the community council activities through PORTEM platform, TUC will achieve the ideal status of the decentralized but controlled cryptocurrency.

5. PORTEM

PORTEM API In order for our protocol to be truly modularized, we have determined the need foran open

source library to allow developers an easy method of creating their own tools built on top of PORTEM. This means that we should facilitate others to build custom frontends for their communities. We believe that the easiest way to allow for this is to build a Javascript library that has fully decoupled frontend implementations. It would be available in 2019.PORTEM is an Open Source Software. The software is released in a transparent process that allows for independent verification of binaries and their corresponding source code.

Rewards DistributionAll users are required to participate in any kind of activity in the TUC community and the participation and contribution towards the network to be rated and rewarded. The policy and system will be developed as a part of the PORTEM platform.

16

6. Wallet Encryption

Wallet encryption allows users to secure their wallet, so that a user can view transactions and account balance, but are required to enter own password before spending TUC.

This provides protection from wallet-stealing viruses and trojans as well as a sanity check before sending payments.

7. Miner-less

In PORTEM, transactions get attached to the “ LV (Lignum Vitae = Tree of Life)”, our unique Blockchain structure, which is a kind of ‘directed-acyclic-graph (DAG)’ data structure. The details will be announced as it developed by PORTEM engineering team. In general, all that is needed is user’s cryptographic signature on their “send” and “receive” blocks. When the node syncs, it runs through the ledger to ensure that the signatures are authentic. There will be “UVA (UtrumqueValeat Arguer)” who will acts as the arbiter of which double spent block to go through and propagate through the system. In principle, this confirmation could be as quick as seconds when there is a sufficient flow of transactions across the network.

8. TUC Software Architecture

Connectivity (Network) LayerThis layer is networking infrastructure that enables open connectivity between the computing systems of the members of TUC community.

Blockchain layerThis layer represents our own ‘Miner-less’ Blockchain system – Lignum Vitae. Each member of the community maintains a copy of transactions ledger. Without Miners, each member still has a compute and storage capacity to create and validate new block and maintain their own copy of a blockchain.

Currency LayerThis layer has all core functions to create, monitor, and maintain TUC coins. It includes rule and protocols for currency management, currency supply management module, digital wallets module as well as user identity and access management functionality.

Applications LayerApplications layer consists of all user facing applications through which the users interact with the system. Users of the system include System Administrator and Users, depending upon their functions and access levels.

Wyoming Governor, Matt Mead, signing the cryptocurrency bills into law

U.S. State Of Wyoming Defines Cryptocurrency 'Utility Tokens' As New Asset Class

- Wyoming House Bill 70 Signed Into Law

Wyoming government officials believe that it is setting a strong example for the way in which the U.S. government will define cryptocurrencies with the passing of House Bill 70. Labeled the “Utility Token Bill,” Wyoming’s House Bill 70 was passed by the Wyoming State Senate on March 7th of last week. Governor Matt Mead just signed the bill into law this past weekend.

The Utility Token bill was designed to exempt specific cryptocurrencies from state money transmission laws and is the first of its kind to legally define the way in which specific types of crypto tokens are treated by regulatory bodies. The bill excludes “developers or sellers” of tokens from securities laws under the caveat that they meet certain conditions. In order to meet these requirements, the token must not be offered as an investment and must be a vehicle for exchange as a utility token.

13. Conclusion

With the technology that TUC have, we can do more in the future.Because of its high technology, it can predict its future in more and more fields. Based on revenues generated by industry and form classifications, they can be delivered. Instead of unifying the value of the currency with the exchange rate across the border as a whole, we can categorize the currency structure by industry category. We're going to create a new digital currency structure that's reliable and transparent. Companies can avoid the rich and the poor by preventing the monopoly of their business.We can expect a just society to be with us.

Blockchain technology has proven to be a disruptive revolution and innovation for many industries, particularly the finance industry. With its presence as one of the main 10 developing advances in 2017, its maturity has seen blue-chip companies recognize it as a potential disruptor. The Blockchain revolution, however, can only remain if it is embraced by every industry.

Leveraging on the over US$ 600 billion market capitalization of cryptocurrencies as of the end of May 2018, TUC Technology will bring ease of use to the world for utilizing digital assets, as customers can use TUC anywhere in the world. Customers will also have the capacity to enjoy all the products and services in the U-Mind Space Like-Minded Community with TUC.
