This technology is being talked about by every business and investor. Blockchain started its journey as an underlying Bitcoin exchange technology, and it has gained so much popularity over the years. Everyone speaks about Blockchain, from students to working professionals; but what makes Blockchain so attractive is that you need to know the concepts of Blockchain technology for this.

An Overview of Cryptocurrencies

Rizal Mohd Nor

Imagine being able to send any amount of money to anyone anywhere in the world at any time without the possibility of funds being frozen, seized, confiscated, or impeded in any way all for a tiny or no cost. That is Bitcoin. Bitcoin has opened the monetary Pandora’s Box. Since Bitcoin slithered out of the primordial monetary ooze in 2009 the Bitcoin economy has been growing, dying, regenerating, evolving, metastasizing, and developing at an extremely rapid pace. One thing is for sure: Bitcoin has not disappeared. This decentralized peer-to-peer irreversible non-freezable crypto-currency, the ultimate ‘offshore bank account’ or last plane account, and the surrounding services now offer tremendous utility to hundreds of thousands of people on a daily basis.

The BSV Association recently conducted a survey of members in its ecosystems to look at the different ways it can improve the digital wallet experience. The survey, which was conducted in July 2023, focused specifically on how the user experience around digital wallets can be improved. Participants were also asked about their personal preferences around choosing a wallet, how they access and use their wallets and the importance of privacy and customer support. This information is invaluable and the BSV Association and its partners at TAAL would like to extend their heartfelt thanks to all those who participated and offered their feedback.

In the first session on day two, Dr Craig Wright discussed the concept of ordering transactions and having path-based sessions. He also discussed some of the practical use cases for nLocktime. In the second session on day two, Dr Wright asked attendees to think of ways to use time-locked Deterministic Finite Automata (DFAs) to create processes for creating products or services. This included everything from shipbuilding and construction to issuing degrees. In the third session on day two, Dr Wright looked at the usage of nLocktime contracts in supply chains and services. He also held a workshop with attendees imagining different products and services that can be created using them. In the final session on day two, Dr Wright asked the attendees to think of ways to use nLocktime to make business easier for small to medium companies, such as by helping them raise money, sell bonds, and capture market data.

In the first session of the Bitcoin Masterclass in Slovenia, Dr Wright discussed IPv6 and how it will work alongside Bitcoin to create a truly distributed, permissionless peer-to-peer network with no scaling limit. He opened the session by discussing the basics of IPv6, anycast, multicast and IP-to-IP. In the second session, Dr Wright discussed the various use cases for IPv6 and Bitcoin and how the two technologies can work together to create a new Internet. In the third session on day one, Dr Wright discussed wallets and overlay services on Bitcoin. He also gave an overview of the different peer-to-peer services which can be built on the technology and why the Internet needs to fundamentally change. In the final session on day one, Dr Wright discussed how blockchain can be used across a variety of sectors including the food industry and hotels.

Dr Wright began the second day by discussing the monitoring of transactions across multiple systems and linking these to a single user. Wright also explained what on-chain receipts could look like - and how these can be private, with the data not visible to just anyone on the public blockchain. Read and watch: https://www.bsvblockchain.org/news/monitoring-transactions-across-multiple-systems In the second session on day two, Dr Wright discussed Benford transactions and how they relate to privacy. Wright refers to ‘Benford’s Law’ in accounting as a means to spot unusual activity in seemingly random series of transactions. Learn more at https://www.bsvblockchain.org/news

What are drone anti-jamming systems? The drone anti-jamming systems and anti-spoof technology protect against interference, jamming, and spoofing of the UAVs. To protect their security, countries are beginning to research drone anti-jamming systems, also known as drone strike weapons. The anti-jam and anti-spoof technology protects against interference, jamming and spoofing. A drone strike weapon is a drone attack weapon that can attack and destroy enemy drones. So what is so unique about this amazing system?

Scaling API-first – The story of a global engineering organization

Radu Cotescu

The presentation explores the development and application of artificial intelligence (AI) from its inception to its current status in the modern world. The term "artificial intelligence" was first coined by John McCarthy in 1956 to describe efforts to develop computer programs capable of performing tasks that typically require human intelligence. This concept was first introduced at a conference held at Dartmouth College, where programs demonstrated capabilities such as playing chess, proving theorems, and interpreting texts. In the early stages, Alan Turing contributed to the field by defining intelligence as the ability of a being to respond to certain questions intelligently, proposing what is now known as the Turing Test to evaluate the presence of intelligent behavior in machines. As the decades progressed, AI evolved significantly. The 1980s focused on machine learning, teaching computers to learn from data, leading to the development of models that could improve their performance based on their experiences. The 1990s and 2000s saw further advances in algorithms and computational power, which allowed for more sophisticated data analysis techniques, including data mining. By the 2010s, the proliferation of big data and the refinement of deep learning techniques enabled AI to become mainstream. Notable milestones included the success of Google's AlphaGo and advancements in autonomous vehicles by companies like Tesla and Waymo. A major theme of the presentation is the application of generative AI, which has been used for tasks such as natural language text generation, translation, and question answering. Generative AI uses large datasets to train models that can then produce new, coherent pieces of text or other media. The presentation also discusses the ethical implications and the need for regulation in AI, highlighting issues such as privacy, bias, and the potential for misuse. These concerns have prompted calls for comprehensive regulations to ensure the safe and equitable use of AI technologies. Artificial intelligence has also played a significant role in healthcare, particularly highlighted during the COVID-19 pandemic, where it was used in drug discovery, vaccine development, and analyzing the spread of the virus. The capabilities of AI in healthcare are vast, ranging from medical diagnostics to personalized medicine, demonstrating the technology's potential to revolutionize fields beyond just technical or consumer applications. In conclusion, AI continues to be a rapidly evolving field with significant implications for various aspects of society. The development from theoretical concepts to real-world applications illustrates both the potential benefits and the challenges that come with integrating advanced technologies into everyday life. The ongoing discussion about AI ethics and regulation underscores the importance of managing these technologies responsibly to maximize their their benefits while minimizing potential harms.
