Public Announcement on the Investment Strategy for Layout in the "Blockchain-Powered Electricity Subsidies" Track

Dear Investors,

To seize the core opportunities arising from the integration of energy digitalization and green finance, the manager of this FOF (Fund of Funds), based on in-depth research and judgment on global energy transition trends and the application prospects of blockchain technology, hereby formally announces the special investment strategy for布局 in the "blockchain-powered electricity subsidies" track. This strategy focuses on the innovative application of blockchain technology in power asset financing and people's livelihood protection, aiming to achieve the coordinated growth of commercial value and social value through the selection of high-quality underlying assets.

I. Investment Logic and Core Tracks

Through core mechanisms such as tokenized incentives, smart contract distribution, and distributed ledger management, blockchain technology is reshaping the electricity subsidy model, effectively connecting the key links of power asset financialization and people's livelihood protection, and becoming a core means to address financing barriers and insufficient inclusiveness in the energy industry. Key layout will be made in three major segmented directions:

1. Asset Tokenization Financing Field: Focus on platform-based projects that convert physical energy assets such as solar panels and microgrids into digital assets. By supporting crowdfunding and fractional ownership transactions, the threshold for initial investment in clean energy projects is reduced.

2. Peer-to-Peer (P2P) Energy Trading Field: Layout technology service providers that empower prosumers to directly trade surplus clean energy. Relying on low transaction fees and tokenized incentive mechanisms to achieve subsidy-like effects, reducing reliance on centralized power systems.

3. Decentralized Power Management Field: Pay attention to smart contract solutions adapted to microgrids and virtual power plant (VPP) scenarios. Through automated subsidy distribution and usage tracking, improve the operational efficiency and risk resistance capacity of power systems.

II. Selection Criteria for Underlying Assets

This FOF will adopt a "quantitative + qualitative" combined screening system to select high-quality underlying funds and project targets that meet the following criteria:

• Technology Maturity: Prioritize blockchain projects based on low-energy consensus mechanisms such as Proof of Stake (PoS), with core technologies verified by benchmark cases such as Power Ledger and SolarCoin.

• Financing Empowerment Capacity: Focus on evaluating the process optimization efficiency of projects invested in by underlying assets (targeting more than 50% simplification of financing processes), capital leveraging scale (prioritizing projects with single-project financing exceeding 1 billion US dollars), and asset implementation progress (prioritizing those with gigawatt-level clean energy project reserves already achieved).

• People's Livelihood Value and Compliance: Select targets that can substantially reduce energy costs in low-income or off-grid areas (targeting a reduction of more than 15%) and have clear regulatory compliance paths, to avoid risks arising from differences in cross-regional regulatory policies.

• Team and Operational Strength: Prioritize underlying funds whose investment and research teams have a composite background in the energy industry and blockchain technology, and whose previously managed projects have achieved dual results of "asset appreciation + people's livelihood protection".

III. Track Prospects and Expected Value

(I) Industry Fundamental Support

Currently, the global annual financing gap in the energy efficiency field reaches 231 billion euros, with more than 700 million people affected by energy poverty. Through transparent subsidy circulation and decentralized transactions, blockchain technology is becoming a key tool to fill the financing gap and alleviate energy poverty.

LSTM Core Formulas
The update formulas for the LSTM unit (simplified single-layer version) are as follows, a variant of RNN designed to handle sequential dependencies:
Forget Gate (determines how much old information to discard): ( f_t = \sigma(W_f \cdot [h_{t-1}, x_t] + b_f) ) where:
( \sigma ) is the sigmoid activation function: ( \sigma(z) = \frac{1}{1 + e^{-z}} ).
( h_{t-1} ) is the hidden state from the previous time step.
( x_t ) is the current input (here, the embedded vector of ( r_t )).
( W_f, b_f ) are trainable weights and biases.
Input Gate (determines how much new information to add): ( i_t = \sigma(W_i \cdot [h_{t-1}, x_t] + b_i) ) ( \tilde{C}t = \tanh(W_C \cdot [h{t-1}, x_t] + b_C) ) (candidate value)
Cell State Update: ( C_t = f_t \odot C_{t-1} + i_t \odot \tilde{C}_t ) (( \odot ) denotes element-wise multiplication)
Output Gate (determines how much information to output): ( o_t = \sigma(W_o \cdot [h_{t-1}, x_t] + b_o) ) ( h_t = o_t \odot \tanh(C_t) )
For the entire sequence, after ( T ) steps, the final hidden state ( h_T ) is passed through a fully connected layer to output the prediction: ( \hat{r}_{t+1} = W_h \cdot h_T + b_h )
Derivation Note: These formulas originate from Hochreiter and Schmidhuber’s LSTM paper (1997). The forget gate prevents vanishing gradients, while the input/output gates control information flow. We train the parameters ( W, b ) via backpropagation (using the Adam optimizer) to minimize the mean squared error loss: ( L = \frac{1}{N} \sum (\hat{r}{t+1} - r{t+1})^2 ), where ( N ) is the number of samples.

Model Assumptions and Data Input
Input Features: Assume we use the standardized return sequence of the past ( T ) time steps ( r_{t-T:t} = [r_{t-T}, r_{t-T+1}, \dots, r_t] ), where ( r_t = \frac{P_t - P_{t-1}}{P_{t-1}} ) (( P_t ) is the closing price at time ( t )).
Target: Predict the next period’s return ( \hat{r}_{t+1} ).
Why LSTM? It excels at capturing long-term dependencies in time series, suitable for the non-stationary nature of financial data.
