In this online talk, we explore chain abstraction, a revolutionary approach enhancing blockchain interoperability and scalability, with a focus on the NEAR protocol. We'll dive into how chain abstraction enables seamless integration across blockchain networks, spotlighting NEAR's role in promoting a cohesive digital infrastructure. Attendees will learn how this approach, supported by NEAR's capabilities, overcomes barriers between blockchain ecosystems, streamlining processes, reducing costs, and boosting transaction security. Discover how chain abstraction, through NEAR protocol's innovative features, is forging a more interconnected future in blockchain space. Join us for insights into a more efficient and secure blockchain future.

Within the last years distributed ledger technologies like Blockchain and Hashgraph have become a part of our modern world. But in the developer community not all people like this hype, and that technologies are often are seen as buzzwords for managers. Sadly some questionable use cases for NFTs has been pushed by the media and most people think NFT is synonymous with speculative PNGs like bored apes!

In this session we will show real use cases of distributed ledger technologies that go beyond cryptocurrency or speculative PNGs. All this can be achieved by using open services that are based on leading and public distributed ledgers like Hedera or Ethereum. In several examples we will present real world use cases that use such services.

Let's dive into every developer's worst nightmare: end-to-end (e2e) testing. While in Web2 we got used to testing to ensure that the entire application, from the user interface to the backend systems, functions correctly and seamlessly. Web3 has a different setup and testing applications requires an understanding of blockchain technology, smart contracts and how to deal with Web3 tools. In this talk we will explore everything you need to know with a hands-on demonstration that showcases how to test your own Web3 applications effectively.
