Our Solution & Features
A Revolution in DeFi Trust and Security
COSINE adopts an innovative strategy, combining on-chain data and machine learning mechanisms to provide dynamic and secure credit scoring. Using a weighted voting system and real-time updates, COSINE assesses risk without requiring your personal information.
Cosine Similarity & Simplified Verifications:
COSINE
Our protocol calculates a normalized score for each wallet and applies cosine similarity to compare wallet reliability against confidence thresholds. This allows lending platforms and DAOs to quickly verify that a user meets security criteria without handling sensitive data.
Layer-2 Infrastructure & Efficient Processing
COSINE
Credit scoring and penalty calculations are processed on an optimized sidechain, ensuring speed and adaptability. Summary information is then stored on the main blockchain, ensuring transparency and integrity.
Evolving Credit Score Embeddings
COSINE
Each wallet is assigned a normalized credit score that automatically adapts to its activities. Through continuous updates and Kalman Filters, the score evolves without exposing any personal data.
VRF Validator Selection & Reputation-Based Governance:
COSINE
A verifiable random selection system (VRF) and reputation-based governance ensure reliable and impartial participation across the network.
Fraud Detection & Community Rehabilitation:
COSINE
Using random time windows and multi-hop analysis, the protocol quickly identifies fraudulent activities. Suspicious wallets see their scores drop, and associated addresses are partially penalized. However, the community can vote to rehabilitate a wallet if positive actions are observed over time.
Token Usage and Fee Structure
COSINE Token Principles
Total Supply: 1,000,000,000 tokens
Staking: Minimum 100,000 tokens to become validator
Validator Rewards: Distribution from reward pool for active participation
The token is also used to compensate validators for regular send and receive transactions
Prevent Spam and Preserve Value
Cost Accumulation: Credit score updates generate costs that accumulate in an internal ledger
Verification Fees: On-chain verification requests require payment in COSINE tokens for accumulated costs
Sustainability: Token burning during verifications offsets emission for rewards, stabilizing supply
COSINE TOKENS
60.00 CHF for 900 tokens
The token price is set at 15 cents CHF, which means a minimum purchase of 900 tokens costs 60 CHF.

FAQs
COSINE is a dynamic and decentralized Layer-2 protocol that generates a real-time credit score for each wallet. By combining reputation-weighted votes and self-adjusting mechanisms, COSINE helps assess user reliability without requesting personal data.
COSINE uses cosine similarity and an evolving score to measure wallet reliability. By integrating continuous updates and gradual penalties, the protocol digitalizes trust by offering both transparency and flexibility in the DeFi ecosystem.
In decentralized finance, privacy must be respected to limit abuse and strengthen user trust. COSINE doesn't require personal data and operates via globally accessible scores rather than nominative information. Thus, each score update preserves user security and anonymity.
COSINE combines multi-hop analysis, random time windows, and community voting to identify and penalize suspicious activities. Malicious wallets are quickly penalized, and those associated with them may also see a score decrease. This graduated mechanism protects the ecosystem while offering a path to rehabilitation for unfairly affected wallets.
For each relevant event (transaction, vote, fraud suspicion), the protocol calculates a score variation using Kalman Filters and penalty/reward factors. These successive updates make the system ultra-reactive and ensure that the rating reflects the most recent behaviors.
COSINE relies on sequential voting where each user's reputation influences their voice's weight. If a wallet is reported for fraud, the community can vote for real-time penalties, then rehabilitate the address when behaviors improve. Decisions are thus built collectively and evolutively.
