Lumino Secure Multi-Party Computing: A New Generation Of Data Security Sharing Solution
The Dilemma Of Digital Economy
The most critical and cardinal element of the digital economy is data. Data is the “oil” of digital economy. Hence, utilizing the “data oil” safely and efficiently is the focal point of global economic digital transformation. On the one hand, the digital economy has entered a high-speed development age. The global digital economy has reached 36.2% of global GDP. It is necessary to open up the “data island” among enterprises and establish an open and shared digital resource environment. On the other hand, the public is paying more and more attention to personal privacy and data security, and regulators have introduced a series of regulations to ensure information security. For example, car companies buy parts back and assemble them into cars, the ownership belongs to the car companies, while parts manufacturers also make it clear that once the parts are sold to factories, the factories have ownership. But the data level is more sensitive. Personal data include the face, voice, name, height and other sensitive personal privacy specifics. How to define the ownership of the data between these parties? At present, there are no clear legal provisions, nor the industry has clear answers. In foreign practice, the EU has made very strict data protection regulations, but the entire EU data information technology industry lags behind China and the United States.
Because data protection is too strict, data from different sources do not interact, data is not open and can not interact to generate value and to improve the efficiency of the economy as a whole. The EU is not a good example, because it does not balance the relationship between data privacy protection and the development of the data industry.
Privacy protection and data security need multi-party promotion
Facing the dilemma of data security and sharing, the “available and invisible” secure multi-party computing provides us with an innovative solution.
Secure multi-party computing is a calculation process performed by multiple participants. Multi-party computing technology includes inadvertent transmission, secret sharing and confusing circuit. Multi-party computing has the advantage of high confidentiality and maneuverability, and each party has absolute control over the data it owns. Secure multi-party computing can be applied to networks where participants are not trusted. Participants can know the agreed results of collaborative computation, but they can’t get or deduce the original contents of the data. The flow of data and the collaborative analysis are of great value in all industries, and have brought about a lot of application demands. There are two main scenarios in the market:
1) Data security query
In the big data age, the data that the enterprise holds itself often cannot satisfy the demand of business analysis, many enterprises will purchase the external data to expand the data source. When an enterprise uses an external database to query, it faces the risk of divulging the query condition information. MPC technology helps enterprises to set up a secure query to obtain more external data under the condition of ensuring their own data security, thereby deepening the digital transformation and making better use of big data technology to optimize business.
2) Data joint analysis
Joint analysis often faces two headwinds. On one hand, it is illegal to trade personal privacy information. On the other hand, data sharing makes data-holding companies lose their competitive edge. MPC technology, through inadvertently querying, makes the data not public, the query object not exposed, and the results can be correctly given feedback for, which has an important application in the financial risk control business.
Lumino: new ideas for secure multi-party computing
Lumino is a large-scale activity that uses secure multi-party computing protocols to generate zero knowledge proof system public reference string (CRS) in a de-trust manner, and it is a prerequisite and an important step for deploying and using privacy-related applications in a decentralized ecosystem. The activity now focuses on the PLONK algorithm. As a practical and efficient zk-SNARK algorithm, PLONK is often used in blockchain projects and communities, which is characterized by only one-time initialization process, i. e. running once, it can be used to support a variety of underlying circuit logic and multi-class application deployment.
Lumino’s vision, from the start, was to link the world’s cryptographic geeks to become co-creators and witnesses of privacy computing infrastructure, not just an event but a ritual. We changed the method of centralizing system parameters into a distributed one. For a truly community-based and open-source blockchain ecosystem, each of which is the most critical link, and each participant who joins makes the bottom one safer, which would be a ceremonial collective wisdom.
Lumino is the cornerstone of subsequent de-centering privacy protection applications based on zero-knowledge proof, and the subsequent de-centralization applications will be safer only if the activity is safely completed.

Optimize Your QuickBooks File and Boost Accounting Performance
Kingston, 27th November 2025, ZEX PR WIRE, As businesses grow and transaction volumes increase, QuickBooks company files can become large and unwieldy, which often leads to slower performance and potential data issues. Optimizing your QuickBooks file is crucial to maintaining fast, reliable, and error-free accounting software that supports your day-to-day financial operations effectively.
A primary reason for slow QuickBooks performance is the increasing size of the company file. Over time, as more transactions accumulate, the file can become fragmented and bulky, making routine processes like opening reports, saving data, or running backups take longer than necessary. This can disrupt workflow and even increase the risk of data corruption. Therefore, regular maintenance and optimization are essential to prevent these issues and keep QuickBooks running smoothly.
One of the fundamental steps in file optimization is verifying and rebuilding the company file. QuickBooks includes built-in tools that check for data integrity problems and attempt to repair them. Running the Verify Data utility helps identify issues such as inconsistencies or missing information, while the Rebuild Data tool works to fix those problems and improve the overall file structure. These utilities should be used periodically, especially if you notice slowdowns or errors during your accounting activities.
Another important aspect of optimization is managing the size of your file by archiving or condensing old data. QuickBooks allows users to remove or archive transactions that are no longer needed for daily operations but must still be retained for compliance or historical reference. By condensing the file and removing outdated details, you reduce clutter and free up system resources, resulting in quicker performance. However, this process requires careful planning because once data is condensed, it cannot be easily restored.
In addition to managing transactions, controlling the size of your lists — such as customers, vendors, and items — also impacts file performance. Large lists can slow down QuickBooks and cause delays in searching or selecting entries. Periodically reviewing and cleaning up inactive or duplicate entries helps maintain a streamlined database.
Keeping your QuickBooks software up to date is another critical factor in file optimization. Intuit regularly releases updates that include performance enhancements, bug fixes, and improved data handling capabilities. Running the latest version ensures you benefit from these improvements and reduces the likelihood of encountering known issues.
For many businesses, working with a certified QuickBooks professional or accountant can make a significant difference in optimizing the company file correctly. Experts can guide you through the verification and rebuilding process, advise on data archiving strategies, and help implement best practices for maintaining a healthy file.
In summary, QuickBooks file optimization is a vital ongoing process that helps businesses maintain efficient accounting systems. Regular verification and rebuilding, archiving old data, managing list sizes, and staying updated with software versions all contribute to a faster, more reliable QuickBooks experience. By investing time in optimization, businesses protect their financial data and ensure their accounting software remains a powerful tool for growth and decision-making.

A professional approach to migrating QuickBooks accounting from Canada to the UK
Brandon, MB, 27th November 2025, ZEX PR WIRE, As businesses expand internationally, managing accounting systems across different countries becomes an essential challenge. QuickBooks, a leading accounting software, is widely used by businesses in Canada and the UK, but transitioning from the Canadian version of QuickBooks to the UK version requires careful planning and understanding of the key differences between the two.
QuickBooks offers country-specific versions that align with the local tax laws, payroll regulations, and currency requirements. The Canadian version is designed around Canadian tax codes such as GST, HST, and PST, with the default currency set to Canadian dollars. On the other hand, QuickBooks UK focuses on UK tax requirements like VAT and PAYE, and operates with British pounds as the standard currency. Due to these fundamental differences, data files created in QuickBooks Canada cannot be directly imported into QuickBooks UK, which makes the transition process more complex than a simple file transfer.
One major aspect to consider when moving your QuickBooks data from Canada to the UK is currency conversion. Since your financial records are likely maintained in Canadian dollars, converting these figures accurately into British pounds is crucial to maintain financial integrity. QuickBooks UK supports multiple currencies, but you must ensure that exchange rates are correctly applied to avoid discrepancies in your financial statements.
Tax compliance also demands attention. The Canadian tax system uses GST, HST, and PST, which have no direct equivalents in the UK. Instead, UK businesses deal primarily with VAT, and the government has implemented digital filing mandates such as Making Tax Digital (MTD). This means that when transitioning to QuickBooks UK, you will need to update your tax settings to align with HM Revenue & Customs (HMRC) requirements and set up VAT reporting accordingly.
Payroll is another significant area where differences arise. The Canadian payroll system integrates with agencies like the Canada Revenue Agency (CRA), while the UK payroll must comply with PAYE regulations and National Insurance contributions. Consequently, you will need to configure payroll in QuickBooks UK to meet these standards and ensure employee records are updated accordingly.
Since QuickBooks data files are tailored to their respective countries, migrating data from the Canadian version to the UK version cannot be done through a simple file import. Instead, businesses often export critical information such as customers, vendors, chart of accounts, and account balances from QuickBooks Canada in a CSV format and then import this data into a new UK QuickBooks file. Some third-party migration tools may assist with this process, but caution is needed to ensure the migration respects both countries’ accounting and tax standards. For smaller businesses, manually entering opening balances and other key data might be a practical option.
Additionally, it is important to review and adjust your chart of accounts to comply with UK accounting practices and tax reporting requirements. Consulting with a UK accountant familiar with these standards will help ensure your financial structure is set up correctly.
Finally, user training and support should not be overlooked. The transition involves adapting to new features and compliance requirements, so providing adequate training for your team is essential. QuickBooks UK offers tailored support and resources that can help ease this adjustment.
In summary, while QuickBooks is a powerful tool that can support your business both in Canada and the UK, moving your accounting system between these countries requires understanding the differences in currency, taxes, payroll, and data management. Careful planning and professional guidance will help make this transition smooth, keeping your business compliant and ready to thrive in the UK market.
