I feel that Blockchain will be technology that forms the economy of value for the world and it can decrease the barriers to entry for various organizations. To me Blockchain technology provides a way to create ecosystems that can bring people together to work cooperatively to achieve something.
I am good at Protocol Design and Blockchain Development. One of the most challanging projects I have worked on is Storage Rent. As the current model of charging users of Ethereum only for the amount of storage but not on time scale is a challange in Ethereum that needs to be solved to make Ethereum sustainable from a storage point of view(This is one of the approaches but there are other approaches like stateless clients). There were significant challanges with the protocol design as I have also designed for features like reusability of code when multiple instances of code is deployed. More details about the approach I have taken and how I solved these challanges is at https://ethresear.ch/t/improving-ux-for-storage-rent/3994 . I have learnt alot about how complex it is to design a new feature into Ethereum and make sure that not to introduce any attack vector into the system. I have also worked on creating a framework to introduce failures into Blockchain systems and understand how the Blockchain platforms handle these failures based on some metrics.
I have an unique vantage point in the Ethereum space as I have worked on lot of Business usecases and understand what is expected from Business to adopt Ethereum and Blockchain in general as a technology. Also as I have been involved in core scaling research of Ethereum on sharding spec 0 and worked with various scaling techniques, I have the ability to understand the upcoming cutting edge research in Blockchain and apply it to solve Business problems.
