BEIJING, June 29, 2026 /PRNewswire/ — WiMi Hologram Cloud Inc. (NASDAQ: WiMi) (“WiMi” or the “Company”), a leading global Hologram Augmented Reality (“AR”) Technology provider, announced that they are researching the use of neural networks for machine learning to optimize parameters in the dual-field quantum key distribution (TF-QKD) system. This innovative approach aims to leverage the powerful fitting ability and generalization performance of neural networks to directly predict the optimal parameter configuration for the TF-QKD system, significantly reducing computation time and resource consumption.

In the study, WiMi trained and evaluated three different types of neural network models:

Backpropagation Neural Network (BPNN): Based on the error backpropagation algorithm, BPNN minimizes prediction errors by continuously adjusting the network weights and biases. Due to its flexibility and wide applicability, BPNN has become the preferred model in many fields.

Radial Basis Function Neural Network (RBFNN): Using radial basis functions as activation functions for the hidden layer neurons, RBFNN efficiently handles nonlinear problems and is particularly suitable for high-dimensional data and scenarios requiring high precision.

Generalized Regression Neural Network (GRNN): Based on probability density estimation, GRNN uses kernel function methods to achieve nonlinear regression, excelling in handling small sample data and uncertainty issues.

Through training and testing these three neural network models, WiMi found that all models could accurately predict the optimal parameters of the TF-QKD system to some extent. Among them, RBFNN and GRNN performed especially well in high-dimensional parameter spaces, showing higher prediction accuracy. Compared to LSA, the neural network-based prediction method achieved a significant reduction in computation time, cutting it by multiple orders of magnitude. BPNN, due to its relatively simple structure, had the fastest computation speed; whereas RBFNN and GRNN, though slightly more complex in terms of computational cost, still remained within acceptable limits, and their enhanced prediction accuracy often brought more practical application value.

Considering the varying optimization needs of different TF-QKD systems (such as real-time requirements and precision demands), WiMi also conducted a comprehensive comparison of prediction accuracy and time consumption. The results indicate that for scenarios requiring rapid response with lower precision demands, BPNN is the ideal choice. On the other hand, for applications that prioritize high accuracy and can tolerate certain computation time, RBFNN or GRNN is more suitable.

The main technical advantage of using neural networks for TF-QKD system parameter optimization lies in significantly reducing the computational complexity of parameter optimization, accelerating the key generation rate, and enhancing the system’s real-time responsiveness. Neural networks can automatically learn and adapt to changes in the quantum communication environment, providing the possibility for dynamic adjustment of system parameters. As quantum communication technology develops, neural network models can be further upgraded and optimized to accommodate more complex quantum key distribution protocols and higher security requirements.

In the future, WiMi will continue to deepen its research into neural networks for TF-QKD parameter optimization, exploring more advanced neural network architectures and training strategies, such as deep learning, reinforcement learning, etc., with the aim of achieving more efficient and intelligent quantum key distribution systems. At the same time, it will strengthen integration with quantum communication hardware platforms to promote the practical application and commercialization of quantum communication technologies, contributing to the development of secure and efficient quantum communication networks.

SDK.finance Launches a Real-Time General Ledger for Banks and FinTech Companies

Published

By

The event-driven, double-entry accounting layer converts financial product events into balanced, auditable journal entries without requiring businesses to replace their existing transaction platform.

VILNIUS, Lithuania, Sept. 4, 2026 /PRNewswire/ — SDK.finance, the software foundation for FinTech and payment products, today announced the launch of SDK.finance General Ledger, a standalone real-time accounting module built for banks, electronic money institutions (EMIs), payment service providers (PSPs), FinTech companies and other businesses operating complex financial products.

Financial platforms often distribute transaction data, balance logic and accounting processes across multiple systems. As products expand across payment rails, currencies and customer segments, this fragmentation can create delayed visibility, manual reconciliation work and inconsistencies between operational data and financial records.

SDK.finance General Ledger can be added as an extra accounting layer to existing payment or banking infrastructure without replacing or modifying the underlying product. It consumes business events from a core banking system, payment platform, digital wallet or other transaction engine and automatically converts them into balanced double-entry journal entries.

This gives financial businesses a consistent, real-time and auditable system of record while allowing them to retain their existing transaction infrastructure.

“Financial businesses need to know not only that money moved, but how every event affected every relevant account, immediately and with a complete audit trail,” said Alex Malyshev, CEO of SDK.finance. “We built SDK.finance General Ledger as a standalone accounting layer that can work with the infrastructure a company already has. It helps technical and finance teams work from the same financial truth while retaining control over their architecture, data and future development.”

From business events to auditable accounting records

SDK.finance General Ledger uses configurable accounting determinations and mapping rules to translate product-specific events into journal-entry legs. It validates that debits and credits are balanced, posts entries automatically when configured and updates account balances and turnovers in real time.

Once posted, journal entries remain immutable. Corrections are handled through reversing entries, preserving the original record and maintaining a clear history of every adjustment.

As a standalone module, SDK.finance General Ledger connects to existing financial infrastructure through Kafka or REST API. It receives business events, generates the corresponding accounting entries and returns confirmations to the originating system.

The integration does not require changes to the existing transaction-processing logic. This allows businesses to introduce a dedicated accounting layer without rebuilding or replacing their current platform.

Core capabilities include:

Automated conversion of business events into balanced debit and credit entriesReal-time account balances and turnover reportingConfigurable chart of accounts, accounting determinations and mapping rulesImmutable posted entries and reversal-based correctionsSupport for fiat currencies and digital assets, with precision of up to 18 decimal placesRole-based access control and a traceable audit historyIntegration through Kafka and REST APIsStandalone deployment alongside an existing core banking system, payment platform or transaction engineSource code access for organisations that require greater control and customisation

Built for financial products that move money

SDK.finance General Ledger is designed for organisations that need to account for high volumes of financial events accurately across multiple products, currencies or systems.

Typical applications include:

Banks and EMIs adding real-time accounting capabilities to existing core infrastructurePSPs managing fees, settlements and transactions across multiple payment railsDigital wallets and neobanks maintaining real-time customer and operational balancesRemittance and payout platforms handling cross-border and foreign-exchange flowsEmbedded finance providers adding auditable financial functionality to non-financial productsMarketplaces recording split payments, commissions and merchant liabilitiesDigital asset businesses accounting for fiat and crypto-related events within a consistent framework

SDK.finance General Ledger can be deployed as a standalone module alongside an existing core banking or payment platform. It can also be combined with the SDK.finance Transaction Platform as part of a broader financial technology stack.

This deployment flexibility allows financial businesses to add a specialised accounting capability while preserving their existing customer journeys, payment logic and operational infrastructure.

About SDK.finance

SDK.finance is the software foundation for FinTech and payment products. With more than 15 years of industry experience, the company provides a modular software suite that helps banks, FinTech companies, EMIs, PSPs and enterprises build, modernise and scale digital financial services.

SDK.finance combines pre-developed transaction and accounting capabilities, flexible deployment options and source code access. This approach enables businesses to customise their financial infrastructure, maintain control over their product development and reduce long-term vendor dependency.
