10 11 Applying patented blockchain technology, D-Engraver Limited has developed an all-in-one deal-closing platform, with two brands — HashTag and HashSign — to facilitate remote business activities/ operations, maintain high security, and ensure traceability for all industries. The underlying technology, D-Engraver Chain, breaks through the limitations of conventional blockchain architecture, such as slow processing speed, overwhelming data storage requirements, and high maintenance cost. By overcoming these barriers, D-Engraver Chain has established a foundation for the mass adoption of blockchain across industries. HashTag and HashSign enable multiple parties across regions to sign contracts in real time, while ensuring the signature record is immutable, thereby forming a reliable and complete evidence chain. This not only enhances deal closing and operational efficiency but also produces digital documents and contracts that have the same legal binding effect as physical documents. d-engraver.com shingngaiman@d-engraver.com data_engraver d-engraver-limited Dayta AI is a SaaS company with a vision of establishing a SmartRetail ecosystem that entails computer vision and business intelligence. With the rise of e-commerce and now the pandemic, the role of bricks-and-mortar stores is clearer than ever before — extending excellent service and building trust and relationships with customers. Nevertheless, traditional solutions require either high up-front costs or long hardware installation time. Our innovative cloud solution, Cyclops, only requires existing surveillance footage to run. Users can manage stores on a real-time basis, gain deeper insights through customized business intelligence reports, and as a result, implement data-driven strategies to enhance sales and shopper experience. dayta.ai patricktu@dayta.ai daytaAI daytaai
