+# DMind-2: Edge-Deployed Web3 Investment Intelligence Model
+## Model Overview
+DMind-2 is a series of Web3 investment analysis language models specifically designed for edge deployment, dedicated to providing real-time, private, and professional Web3 investment consulting services for individual investors and professional institutions. Standing on the shoulders of numerous open-source pioneers, we have successfully launched three model variants through innovative post-training techniques, enabling users to access institutional-grade investment analysis capabilities on local devices without concerns about data privacy or network latency.

+## Technical Innovations
+### 1. Domain-Adaptive Supervised Fine-Tuning (SFT)
+In building DMind-2, we deeply understand the uniqueness of the Web3 investment domain—it requires not only profound blockchain technical understanding but also keen financial market insights, and most importantly, the ability to perform rigorous logical reasoning among complex on-chain data and market signals. Therefore, our domain-adaptive fine-tuning strategy fully considers these requirements from the very beginning of dataset construction. We carefully curated a total of 47.6K high-quality training samples, including 27.8K Web3 domain-specific data points covering comprehensive Web3 investment scenarios from DeFi protocol analysis and NFT valuation models to DAO governance decisions. These data points are not simple Q&A pairs but contain complete investment logic chains, encompassing the entire reasoning process from market observation, data analysis, and risk assessment to investment recommendations.
+To ensure the model maintains fundamental financial analysis capabilities while focusing on the Web3 domain, we specifically incorporated 11.2K high-quality general domain data points and 8.6K pan-financial domain data points. These datasets help the model establish a solid foundation in financial theory and market analysis frameworks, enabling it to creatively apply mature methodologies from traditional finance to the emerging Web3 sector. Through this multi-layered data fusion strategy, DMind-2 can act like a professional investment advisor who understands both technology and finance, providing users with comprehensive and in-depth investment analysis.
+### 2. 🔥 Core Innovation: Distribution-Preserving Chain-of-Thought Distillation (DPCD)
+DMind-2's greatest technical breakthrough lies in our innovative Distribution-Preserving Chain-of-Thought Distillation method. Traditional domain fine-tuning causes catastrophic forgetting in CoT models, where the model loses reasoning coherence while gaining domain knowledge. Our DPCD method solves this through a mathematically rigorous dual-stream architecture.
+#### Core Formulation
+The DPCD optimization objective combines domain adaptation with reasoning preservation through the following loss function:
+$\mathcal{L}_{\text{DPCD}} = \underbrace{\mathcal{L}_{\text{CE}}(\theta_s, \mathcal{D}_{\text{Web3}})}_{\text{Domain Learning}} + \underbrace{\lambda(t) \cdot \sum_{i=1}^{T} \alpha_i \cdot D_{\text{KL}}(P_{\theta_s}^{(i)} \| P_{\theta_t}^{(i)})}_{\text{Distribution Preservation}} + \underbrace{\beta \cdot \mathcal{L}_{\text{QS}}(\mathcal{C}_{\theta_s})}_{\text{Quality Score}}$
+Where:
+- $\theta_s$ and $\theta_t$ represent student (trainable) and teacher (frozen) model parameters
+- $P_{\theta}^{(i)}$ denotes the probability distribution at reasoning step $i$
+- $\lambda(t) = \lambda_0 \cdot (1 + \gamma \cdot \text{complexity}(x_t))$ is the dynamic weight function
+- $\alpha_i = \exp(-\delta \cdot i/T)$ implements exponential decay for later reasoning steps
+- $\mathcal{L}_{\text{QS}}$ is the quality scoring loss ensuring reasoning coherence
+#### Dynamic Weight Adjustment Mechanism
+The complexity-aware weight adjustment is formulated as:
+$\lambda(t) = \begin{cases}
+\lambda_{\text{high}} \cdot \left(1 + \tanh\left(\frac{\mathcal{H}(x_t) - \mu_{\mathcal{H}}}{\sigma_{\mathcal{H}}}\right)\right) & \text{if } \mathcal{T}(x_t) \in \{\text{DeFi Analysis, Risk Assessment}\} \\
+\lambda_{\text{base}} & \text{if } \mathcal{T}(x_t) \in \{\text{Market Data, Price Query}\} \\
+\lambda_{\text{base}} \cdot \left(1 + \frac{\mathcal{S}(c_t)}{|\mathcal{V}_{\text{Web3}}|}\right) & \text{otherwise}
+\end{cases}$
+Where $\mathcal{H}(x_t)$ measures reasoning complexity through chain length and branching factor, $\mathcal{S}(c_t)$ counts domain-specific terms, and $|\mathcal{V}_{\text{Web3}}|$ is the Web3 vocabulary size.
+This mathematical framework ensures that DMind-2 maintains Qwen3's powerful reasoning capabilities while acquiring deep Web3 domain expertise. The KL divergence constraint operates at each token generation step, preserving the original model's reasoning patterns. The quality scoring mechanism $\mathcal{L}_{\text{QS}}$ filters out low-quality reasoning chains, maintaining only those paths with coherence scores above threshold $\tau = 0.85$.
+Through extensive experimentation, we found optimal hyperparameters: $\lambda_{\text{base}} = 0.3$, $\lambda_{\text{high}} = 0.7$, $\beta = 0.2$, and $\delta = 0.1$. This configuration achieves a 94.1% reasoning chain completeness while improving domain-specific accuracy by 23.2% over baseline fine-tuning methods.
+### 3. Reinforcement Learning from Human Feedback (RLHF) Optimization
+After completing basic domain fine-tuning, we further optimize the model using the Group Relative Policy Optimization (GRPO) algorithm. GRPO offers better stability compared to traditional PPO algorithms, which is particularly important for financial domain models—we cannot tolerate dramatic performance fluctuations during optimization as this could lead to unpredictable investment advice. During the RLHF phase, we focused on addressing two key issues: professional output formatting and safety compliance.
+For professional output formatting, we constructed 4.2K carefully designed professional format data points. These data samples are sourced from real investment research reports, market analysis documents, and project due diligence reports, covering all aspects of investment analysis. Through RLHF training, the model learned how to organize a professional investment analysis report: starting with an executive summary that clearly articulates investment opportunities and risks; conducting in-depth technical analysis and market evaluation in the main body; and finally providing clear investment recommendations and risk warnings. This structured output not only improves information readability but more importantly helps investors establish systematic analytical frameworks, avoiding impulsive investment decisions due to disorganized information.
+Safety alignment is another aspect we particularly emphasize. The Web3 investment field is full of high-risk, high-reward opportunities, and the model must accurately identify and highlight potential risks. We use proprietary risk case datasets to conduct safety training on the model, ensuring it won't output overly optimistic investment advice or overlook obvious risk signals. For example, when analyzing an emerging DeFi protocol, the model automatically checks key risk indicators such as smart contract audit status, team background, and total value locked, explicitly marking risk levels in investment recommendations. This responsible output approach not only protects users' asset security but also reflects our commitment to financial compliance.
+## Application Scenarios
