4. Solution: Viber Platform Architecture

---

4.1 Infrastructure Layer: Solana-based Token System

Technology Selection Rationale

Item	Solana	BSC	Ethereum
Average fee	$0.0001-0.001	$0.003	$5-15
Block finality	400ms	3 seconds	12 seconds
TPS	65,000+	160	15-30

Selection rationale: Fan participation relies on small, high-frequency transactions (voting, membership verification, reward claiming). Solana’s low-cost, high-speed processing is essential for UX.

Core Components

Component	Technology	Role
VIBER Token	SPL Token	Staking, voting, membership, payments
Staking Contract	Anchor Program	Reward distribution, tier calculation
Treasury	Squads Protocol	3/5 multisig, buyback execution
ZK Verification	Bonsol (RISC Zero)	Membership credential verification

Treasury Security Policy

Spending size	Approval requirement	Timelock
Under $10,000	2/5 signatures	Immediate
$10,000-$100,000	3/5 signatures	24 hours
Over $100,000	4/5 signatures	72 hours
Contract upgrade	5/5 signatures	7 days

4.2 Privacy Layer: ZK Membership Verification

Problem Recognition

Limitations of existing blockchain membership systems:

• Wallet balances are public, causing privacy violations

• VIP credential checks inevitably expose holdings

• This discourages participation by celebrities/high-value holders

Viber’s Approach

ZK-SNARK-based credentials: users prove only whether they meet “specific conditions,” without revealing actual holdings.

[Proof Process]

User wallet
    │
    ├─ Holdings: 50,000 VIBER (private)
    │
    ▼
Generate ZK Proof
    │
    ├─ Proof statement: "holdings ≥ 10,000" (true/false only)
    │
    ▼
On-chain verification
    │
    ├─ Verification cost: ~$0.001
    ├─ Verification result: "Eligible for Gold tier"
    └─ Exposed info: none

Technical Details

Item	Specification
Proof system	Groth16 (Bonsol/RISC Zero)
Verification cost	~200K CU (~$0.001)
Proof generation	Client-side (2-5 seconds)
Supported proof types	Balance threshold, staking duration, voting eligibility

Scope of Privacy Guarantees

Function	Public information	Private information
Membership verification	Whether tier-eligible	Actual holdings
Voting participation	Vote result aggregation	Individual voting records
Content access	Whether access is granted	Wallet address, balance
Event entry	Whether eligible to enter	Identity, holding history

4.3 Content Layer: Exclusive IP Pipeline

Viber’s Core Competitiveness

4.4 User Experience Scenarios

Scenario A: First participation by an overseas fan

Background: A Japan-based Korean film fan. Likes “The Man from Nowhere” but had no way to participate in the prequel production.

[Step 1: Discovery]
Access the Viber web app from Japan
→ Check the "Participation in the production of the 'The Man from Nowhere' prequel drama" banner
→ Buy VIBER with crypto without a Korean bank account

[Step 2: Staking]
Stake 10,000 VIBER (90 days)
→ Obtain Gold Tier
→ Secure casting voting rights + access to exclusive content

[Step 3: Participation]
Participate in the lead-actor casting vote
→ Vote via ZK proof (holdings not disclosed)
→ Vote result: the actor you supported is confirmed for casting

[Step 4: Content Consumption]
Watch exclusive production-process videos
→ On-set behind-the-scenes, actor interviews
→ Early release 2 weeks before public release

[Step 5: Rewards]
A drama OTT licensing deal is signed
→ Revenue generated → Buyback & Burn executed
→ Token supply decreases → staking reward value increases

Scenario B: Privacy protection for a VIP member

Background: A domestic celebrity. Holds a large amount of VIBER but does not want holdings exposed.

[Problems with the existing approach]
Connect wallet → balance disclosed → "○○○ holds 100,000 VIBER" becomes a news article
→ Investment information exposure, privacy infringement

[Viber ZK approach]
Connect wallet → generate ZK proof → only "Platinum-eligible" is verified
→ Holdings and wallet address are completely undisclosed
→ Eligible to visit the set and attend an actor meet-and-greet
→ No information is exposed externally

Scenario C: Global funding for a production company

Background: A new drama by United Pictures. Conducts global fan funding in addition to traditional investment.

[Existing approach]
Negotiate with investors → complex contracts → only domestic (Korean) capital can be raised
Overseas fans cannot participate

[Viber approach]
Announce VIBER token sale
→ Global fan participation (US, Japan, Southeast Asia, etc.)
→ KRW 3.0 billion-scale funding completed
→ All participants are automatically granted Gold Tier or higher
→ Drama revenue → buyback → participant rewards
