3. Project Background

ZENKOKU ($CDB) is developed by a Japanese company that operates the “National Enterprise Database (https://companydata.tsujigawa.com/).”

Building a “reliable economic zone” through the integration of corporate information and blockchain

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.
• We do not tolerate any acts that undermine the industry, such as rugs (fund-taking).
• We will thoroughly implement a careful development system that places importance on long-term trust and provide transparent information.

7. Use cases (uses)

7.1 Access to Advanced Enterprise Data

Using CDB tokens allows you to access advanced features and authenticated company information on the “Company Database” You can also directly interact between companies using the company dashboard within the national company database.

7.2 Business-to-business (B2B) payments and smart contracts

CDB enables secure payments and automatic settlements with smart contracts between trusted companies.
In payments using $CDB, including a national corporate database, 3% of the $CDB used is burned.
Additionally, 2% Japanese yen is converted to Solana ($SOL) and deposited into the SOL hold pool. (Addresses will be released soon)
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.

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.

7.7 Online Corporate Register Copy Acquisition Service

This service allows you to obtain a certified copy of your corporate register online for just 450 yen per copy.
