1. Overview

A decentralized economic zone that focuses on practicality, connecting Japanese companies and Web3 users

ZENKOKU ($CDB) is a next-generation token project based on transparency and practicality, built together with trusted companies both in Japan and abroad.
This token is built on the Solana blockchain and functions as a utility token that works with a substantive service under the symbol “CDB (Company Data Base).”

In addition to blockchain-based token utility, ZENKOKU aims to transform corporate information, real-time browsing activity, company news, press releases, advertising, and promotional functions within the National Company Database into new forms of value and business opportunity.

As part of this initiative, we are developing CDB LIVE, a real-time corporate marketing platform designed to visualize “current interest” in companies and connect that interest with corporate communication, promotion, and user acquisition.

CDB LIVE represents an evolution beyond the traditional role of a corporate database.

From a place where company information is simply listed, to a platform where companies can connect with users at the exact moment interest occurs.

ZENKOKU’s goal is to increase transparency and reliability in the cryptocurrency industry and create a sustainable ecosystem supported by a healthy layer of holders.

5. Marketing Policy

This project does not carry out any excessive purchase promotion or incitement marketing.
We have already established business relationships with trusted companies, and we plan to carefully and gradually expand our value and use cases.

The launch party is scheduled for next month on the 15th. Then start marketing in stages.

6. Community and Ethics

• ZENKOKU will remain integral to all investors and holders.

Pending SOLs will be used for $CDB Holder Reward, CommunityReward.

7.3 Payment for Press Release Distribution Services

Companies using our press release distribution service will receive special prices when using CDB tokens.
Traceability, fairness and blockchain-level transparency in corporate information transmission are guaranteed.

7.4 Startup Funding Function (Scheduled to be implemented in the future)

In the future, CDB will be utilized in startup fundraising platforms.
Startups can raise funds from token holders through CDB tokens, and investors can participate in early funding through a transparent mechanism. Furthermore, unlike previous fundraising platforms, fundraising can be borderlessly raised from investors from all over the world who find it attractive to you.
This function aims to democratize corporate investment while maintaining strict screening standards.

The startup fundraising function is a system in which small and medium-sized businesses and startups registered on the national corporate database can use ZENKOKU ($CDB) to raise funds in a decentralized manner. Investors and holders can directly support reliable businesses with $CDB tokens.

1. Company Registration and Review (KYC)
   • The startup pays the initial registration fee ($1,000 CDB), registers the business overview, and after passing the screening, it acquires the authority to “apply for funds.”
   • Escrow agreements prevent misuse of funds.
2. Recruitment in crowdfunding format by $CDB
   • Present your target amount, procurement period, and rewards (e.g. token distribution, service usage rights).
   • Procurement is carried out using $CDB or $SOL.
3. Community votes and evaluations
   • Before funding is put in, $CDB holders can “vote project trust” voting.
   • Voting rights vary depending on the amount and duration of holding.
4. Token Value Back (Buyback & Burn)
   • A portion of the amount raised (7%) was bought back $CDB from the market and burned.
   • Contributes to price support and control of circulating supply.

🟢 $CDB Holdings Program for Business

7.7 Holder x Influencer System (CDB Ambassador Program)

■ Summary (What is CDB Ambassador Program?)

To expand ZENKOKU’s ecosystem and maximize the influence of CDB holders, we will introduce the “CDB Ambassador Program.” This is a new system in which holders themselves act as trustworthy information providers, or “influencers,” and receive rewards based on the results.

By utilizing a variety of channels including social media, blogs, YouTube, and media articles, holders spread the value of companies and ZENKOKU within their own network, bringing benefits to both parties.

■ Activity Scope

The CDB holder can be promoted in the following ways:

• SNS posts (X/Instagram/TikTok/Facebook, etc.)
• Creating and streaming blog articles and YouTube videos
• Events and online study sessions
• Introduction activities within your own community and within DAO
• Introduction to products and services from specific companies
• Explanation of CDB token use cases and functions

■ Reward System

Depending on the holder’s activities, rewards will be paid based on transparent evaluation criteria. Remuneration is basically paid in Solana($SOL) and is calculated based on the following valuation criteria:

*A level system (Bronze/Silver/Gold/Elite) is established depending on the activity points, and rewards will be distributed at the end of the month.

■ Ambassador Registration System

Holders who wish to participate in the Ambassador Program will begin registration and activities using the following steps:

1. Application via the dedicated application form
2. After passing the screening, access the dedicated dashboard
3. Selecting promotional projects and starting activities
4. Monthly rewards are distributed on Solana($SOL)

■ The benefits of the program

● Benefits for holders

• You can earn Solana($SOL) as rewards through your own influence
• Increase your trust and status through activities
• Includes perks and awards as an early ambassador

● Benefits for businesses

• Promote with realistic voices from influencers who are already connected to CDB
• Transparency in advertising expenses (Payment traceability using CDB tokens)
• Direct reach of holders that have an impact on niche industries and regions

■ A New Model of Advertising Empowered by ZENKOKU

In today’s advertising industry, a large portion of marketing budgets is absorbed by intermediaries such as ad agencies and consulting firms. As a result, the actual value creators—individual influencers and end users—often receive only a fraction of what they deserve.Moreover, inflated metrics and opaque reporting are common, making it difficult for companies to measure real marketing performance and ROI.

ZENKOKU ($CDB) aims to eliminate this inefficient “middleman structure” and rebuild the advertising ecosystem from the ground up, driven by transparency, fairness, and direct value exchange.Through the CDB Ambassador Program, $CDB holders can act as influencers and connect directly with companies to promote their products or services. This enables a new kind of advertising model where:

• Companies gain access to cost-effective, high-impact promotional efforts with verifiable results
• Holders are fairly rewarded in proportion to the influence and engagement they generate

This creates a Win-Win-Win structure—for companies, for influencers, and for the broader community.

All promotional activities are recorded on the blockchain, allowing transparent tracking of:

• Who promoted
• When and where they promoted
• How much engagement or reach was achieved

This ensures that rewards are distributed transparently and fairly, without manual oversight or subjective interpretation.

ZENKOKU’s vision is to create a new, trust-based advertising ecosystem where influence is respected, value is redistributed properly, and growth is driven by community participation.

7.8 CDB LIVE — Real-Time Corporate Marketing and Promotion Platform

■ Overview — What is CDB LIVE?
CDB LIVE is a real-time marketing infrastructure that visualizes current user interest in companies listed on the National Company Database and connects that interest with corporate promotion, communication, and traffic acquisition.

By utilizing real-time browsing activity generated from search engines and within the National Company Database itself, CDB LIVE can visualize information such as:

• Which companies are being viewed right now
• Which companies are experiencing increasing attention
• Which companies are currently being Boosted
• How many impressions and clicks promotional exposure generates
• How effectively Boost campaigns convert exposure into company page visits

Unlike conventional corporate databases that primarily provide static company information, CDB LIVE is designed to utilize real-time interest in companies at the moment it occurs.

■ CDB LIVE Service Structure

7.8.1 CDB LIVE Viewers — Visualizing Real-Time Interest in Companies

Company pages within the National Company Database can display the number of users currently viewing that company in real time.

Example:

🔴 LIVE — 7 users are currently viewing this company

This allows users and companies to visually understand how much attention a company is receiving at that moment.

CDB LIVE Viewers is not simply a page-view counter. It serves as a foundational component for future real-time marketing functions such as CDB LIVE Ads, LIVE Boost, and LIVE Analytics.

7.8.2 CDB LIVE Boost — Bringing Companies to More Users

CDB LIVE Boost is a promotional function designed to increase a company’s visibility, attention score, and opportunities to be discovered within the National Company Database.

LIVE Boost is available not only to companies seeking greater exposure for themselves, but also to general users who want to support a particular company.

Users may Boost companies they want more people to discover.

Boosted companies may receive additional exposure through LIVE-related areas and discovery features across the platform.

■ Key LIVE Boost Functions

• Adds Boost points to a company’s platform visibility score
• Increases discovery opportunities within LIVE-related pages
• Provides exposure through LIVE tickers and other platform discovery areas
• Displays dedicated Boost indicators for actively Boosted companies
• Creates new paths directing users to company pages
• Displays the number of users who have Boosted a company
• Displays the amount of Boost gained during the past 24 hours
• Measures impressions and clicks generated through Boost exposure

Company pages may display information such as:

⚡ Someone Boosted this company
👥 Boosted by 3 users
🔥 +75 Boost in the past 24 hours

LIVE Boost does not artificially increase or falsify actual real-time viewer numbers.

Boost is used to increase platform visibility, discovery opportunities, promotional exposure, and ranking-related attention within the National Company Database.

7.8.3 A System Where Both Companies and Users Can Support Businesses

One of the defining characteristics of CDB LIVE Boost is that it is not limited to companies purchasing advertising for themselves.

Users visiting the National Company Database may also choose to Boost companies such as:

• Local businesses
• Favorite brands
• Startups they support
• Companies operating services they use
• Business partners
• Companies they are personally interested in

This creates a structure where both:

Corporate self-promotion

and

User-driven company support

can exist within the same platform.

In the future, we aim to develop this relationship beyond the traditional advertiser-and-viewer model and create a community-driven ecosystem in which users can directly support the visibility, recognition, and growth of companies they value.

7.8.4 CDB LIVE Analytics — Making Promotional Performance Visible

CDB LIVE is designed not only to provide promotional exposure, but also to measure its actual performance.

LIVE Boost currently provides analytical functions for metrics including:

• Boost revenue
• Number of Boost purchases
• Number of companies receiving Boosts
• Number of users supporting companies through Boost
• Boost increase during the past 24 hours
• Impressions
• Clicks
• CTR — Click-Through Rate
• Most popular Boost plans
• Ranking of companies receiving Boosts
• Performance by placement and distribution area

This makes it possible to measure:

How many times a company was displayed, how many users clicked, and how much interest was generated through promotional exposure.

In the future, we are also considering providing companies with dedicated dashboards through which they can directly monitor these performance metrics.

7.8.5 CDB LIVE Ads — Advertising to Users Who Are Viewing a Company Right Now

Planned Feature

As the next stage of CDB LIVE, we plan to develop CDB LIVE Ads.

Conventional search advertising primarily targets users based on keywords.

CDB LIVE Ads is designed around a different concept:

Real-time interest represented by the fact that a user is currently viewing a specific company.

For example, when seven users are currently viewing a company page, that company may be able to display promotional information to those users in real time, including:

• New products and services
• Recruitment information
• Whitepaper or document downloads
• Campaigns
• Exhibitions and events
• E-commerce products
• Inquiry and consultation opportunities
• New store or branch information

Search advertising targets keywords. CDB LIVE Ads aims to target real-time interest in companies.

All advertisements and promotional placements will be clearly identified as advertising or sponsored content so that users can easily distinguish promotional content from standard company information.

7.8.6 CDB News Pulse — Connecting Real-Time News Interest with Companies

Planned Feature

The National Company Database provides not only corporate information, but also press releases, company news, and other newly published business information.

CDB News Pulse is designed to utilize real-time interest in those articles and press releases.

Examples may include users currently viewing:

• Artificial intelligence-related company news
• Logistics-related press releases
• Food and restaurant industry articles
• Regional business news
• Startup-related announcements
• Technology and SaaS-related corporate information

Relevant companies, services, and advertisements may then be displayed in connection with the content currently being viewed.

Rather than relying exclusively on demographic targeting, CDB News Pulse aims to utilize:

What users are interested in at this exact moment

to create contextual and real-time corporate promotional opportunities.

7.8.7 The Corporate Marketing Model CDB LIVE Aims to Build

CDB LIVE is not intended to make the National Company Database simply another place where company information is listed.

Our objective is to connect the entire process from the moment interest in a company occurs:

Discovery → Viewing → Promotion → Traffic Acquisition → Performance Measurement

within a single platform.

■ CDB LIVE Ecosystem Flow

7.8.8 Future Integration with ZENKOKU ($CDB)

CDB LIVE is being developed as an active service within the National Company Database.

In the future, we will consider integrating ZENKOKU ($CDB) into corporate promotional services including:

• CDB LIVE Boost
• CDB LIVE Ads
• CDB News Pulse
• Corporate analytics functions
• Premium promotional functions
• Other advertising and discovery services

If $CDB payments are introduced into these services, they can become additional utility use cases for the ZENKOKU ecosystem.

A potential utility cycle would be:

Companies use CDB services

↓

Real demand for $CDB is generated

↓

Value circulates back into the ZENKOKU ecosystem

Any specific Burn, Buyback, reward, or ecosystem redistribution policies related to future $CDB payments for these services will be disclosed separately when each function is implemented and will follow the applicable policies stated in this WhitePaper.

7.9 Online Corporate Register Copy Acquisition Service

For those who want to easily and affordably obtain a certified copy of their corporate register online. This service allows you to obtain a certified copy of your corporate register online for just 450 yen per copy. Easily obtain essential business registration information, such as company research, business partner verification, credit management, and anti-social activity checks, anywhere in the country.

12. Conclusion — Revised Version

ZENKOKU is a utility-focused token project that prioritizes real-world use cases, sustainable ecosystem development, and long-term value creation rather than short-term price speculation.

The National Company Database continues to expand beyond traditional corporate information services.

In addition to company information, press releases, and corporate registration data, the platform is developing practical functions including real-time company viewing activity, CDB LIVE Boost, promotional performance measurement, and future real-time advertising capabilities through CDB LIVE.

ZENKOKU ($CDB) aims to gradually expand integration with these real-world services and build a new corporate economic ecosystem that combines:

Corporate Information × Real-Time Data × Web3

Our objective is to create an ecosystem in which companies, users, holders, and information creators can each contribute value and participate in a transparent and sustainable economic cycle.

By connecting practical corporate services with blockchain-based utility, ZENKOKU aims to become a real-world model for bridging Web3 technology with actual business activity.
