Feature

1. On-Chain Reputation as a Core Primitive

Vitrum introduces reputation as a first-class on-chain primitive, allowing credibility to be transparently measured, verified, and enforced directly at the smart contract level. Reputation is no longer an informal social signal, but a protocol-native asset that can be programmatically consumed by decentralized applications.

2. Soulbound Identity NFT

Each user is represented by a non-transferable Soulbound Identity NFT that permanently binds reputation to a single on-chain identity. This design prevents:

• Reputation trading

• Identity resale

• Low-cost identity resets

By anchoring reputation to a soulbound identity, Vitrum ensures that credibility must be earned over time and cannot be transferred or discarded.

3. Dynamic On-Chain Reputation Scoring

Reputation scores are stored as dynamic on-chain properties, not static NFT metadata. This enables:

• Continuous reputation updates without re-minting NFTs

• Gas-efficient score changes

• Native composability with other smart contracts

Other protocols can read and enforce reputation scores directly on-chain without relying on off-chain indexing.

4. Automated Reputation Scoring with On-Chain Verification

Vitrum combines automated reputation scoring with cryptographic on-chain verification. Reputation is derived from behavioral and activity-based signals analyzed off-chain, then verified on-chain through signature-based validation.

This approach:

• Reduces subjective or manual judgment

• Preserves scalability

• Ensures that all reputation updates are verifiable and tamper-resistant

5. Reputation-Gated Participation

Vitrum enables reputation-gated interactions, where only identities that meet predefined credibility thresholds can participate in sensitive actions such as voting, signaling, or access control.

This mechanism:

• Raises the cost of Sybil attacks

• Filters low-quality or malicious participation

• Ensures that influence is earned, not fabricated

6. Bullish or Bearish Voting System

Vitrum provides a structured on-chain bullish and bearish voting mechanism to generate clear, community-driven credibility signals for influencers, public figures, or initiatives.

Votes are:

• Reputation-gated

• Identity-bound

• Immutable once cast

This ensures that social signals reflect credible conviction, not short-term hype or manipulation.

7. Cryptographic Identity Verification

All reputation-related actions in Vitrum are protected by signature-based cryptographic verification. This guarantees that:

• Reputation updates are authorized

• Identity ownership cannot be spoofed

• Unauthorized score manipulation is prevented

The verification model establishes a clear trust boundary between off-chain analysis and on-chain enforcement.

8. Slash and Enforcement Mechanism

Vitrum includes an on-chain slashing mechanism that allows reputation to be penalized or reset in cases of proven abuse, manipulation, or rule violations.

This feature introduces:

• Accountability

• Enforceable consequences

• Long-term deterrence against malicious behavior

Reputation is not only earned it can also be lost.

9. Composable Reputation Layer

Vitrum is designed as a composable reputation layer, enabling seamless integration across the Web3 ecosystem.

Protocols can leverage Vitrum reputation for:

• Governance voting

• Access control

• Risk assessment

• Sybil resistance

• Social signaling

Vitrum functions as shared social infrastructure, rather than a siloed application.
