Beyond the cycle-driven hype and fear-mongering, blockchain technology continues to be constantly improved and silently innovated by the leading teams from around the world, tackling the famous blockchain trilemma of decentralisation, security and scalability. In this talk we’ll focus on latest industry paradigm and possible solution addressing the issue of blockchain scalability - Appchains. Appchains are purpose or application-specific blockchains, exclusively designed to run a single application instead of multiple applications. They are layered and operate on top of public blockchains like Ethereum or scaling solutions like Layer 2, to which they are connected to and secured by. Appchains offer greatly increased performance, customisation, ownership, and governance, allowing for various and numerous specific use-cases.
