Comparative Study of Web3 Decentralized Solutions

HUMAN Protocol Deep Analysis

HUMAN Protocol is an early decentralized human labor protocol primarily used for data labeling [15].

Privacy Protection	None	ZK Proofs	PACT
Payment Protocol	ERC20 standard transfer	X402 gasless	PACT
Identity System	No unified identity	PactID (SBT NFT)	PACT
Compute Resources	None	PactCompute	PACT
Data Market	None	PactData	PACT

Braintrust Comparative Analysis

Braintrust is a Web3 freelancing platform primarily targeting high-skill professionals [16].

Architecture Comparison:

Braintrust:
- Target users: Software engineers, designers (high skill)
- Task types: Long-term projects (week/month level)
- Verification: Subjective evaluation + complaint mechanism
- Token utility: Governance voting, fee discounts
- Network effects: Single application, limited network effects

PACT Network:
- Target users: AI Agents + Human workers (multi-level)
- Task types: Physical + Digital, short-term + long-term
- Verification: ZK proofs + multi-layer verification network
- Token utility: Universal across 7 applications, strong network effects
- Network effects: Cross-application synergy, exponential growth

Utility Token Design Comparison

According to token economics theory [8], we compare three design patterns:

Dimension	Single-App Token (HUMAN)	Governance Token (Braintrust)	Multi-App Token (PACT)
Utility Scenarios	1	2-3	7
Network Effects	Linear	Sub-linear	Super-linear
Value Capture	Weak	Medium	Strong
Demand Rigidity	Weak (bypassable)	Medium	Strong (required)
Long-term Holding Motivation	Low	Medium	High

Mathematical modeling (based on multi-application utility theory in Section 1.5.3):

Single-app token value: V₁ = k·n^α
Multi-app token value: V₇ = k·n^α·(7 + β·21) (21 = C(7,2) is number of app pairs)

When β > 0.1 and n > critical mass: V₇ >> V₁
