    Problem statement: Its almost impossible to have a single blockchain system used by everyone, we need to find ways to improve current blockchains' interoperability. The blockchain should interact with other blockchain (Ex: Ethereum try to access Hyperledger blockchain's data). Both of these blockchain projects run independently, there is a requirement to have leverage each-other benefits by sharing the information in between (combination of consensus, communication protocols, smart contracts, and data storage). It has to lay a brick in the interoperability using established protocols/frameworks.

    I need an app compatible with Android 10.0. The app must mine the most profitable coins/tokens. It will be installed on android TV boxes. The hardware is Quad-core ARM Cortex-A55 (Amlogic S905X4) 2.0GHz, G31 GPU, 4Gb Ram, 32Gb Rom. Prefer the app to mine tokens that work with the web or 'internet of things' rather than proof of work. The idea is for our users to receive earnings in crypto while they watch tv. Therefore the app should have the capacity for the user to register and add their crypto wallet(s). Also us as a company will receive 50% of earnings to our wallet and the user receives the other 50%. Further information is available for the person awarded the project.
