  • Abstract

    As Don Tapscott once said, "The first generation of the digital revolution brought us the Internet of information. The second generation—powered by blockchain technology—is bringing us the Internet of value: a new, distributed platform that can help us reshape the world of business and transform the old order of human affairs for the better."

    Traditional consensus algorithms like proof-of-work are inefficient at scale, and smart contracts are limited to a single ecosystem. However, by creating a "blockchain of blockchains" architecture, more complex event-driven architectures can be created using separate ecosystems that are independently validated. For example, a smart city could be programmed to execute an emergency shutdown if certain criteria are met. A designer of this system would want to make absolutely sure that the conditions were true before executing a threat response of this magnitude. By having each IoT sensor group that measures a specific environmental condition on its own "sidechain" network, and sharing their "state" to a main authoritative blockchain network, one can create data integrity checks that prevent these programs from triggering by accident in a fault tolerant and distributed manner.
