Paper Title: Proofs of Space Construction - Securing the Blockchain with Storage

Paper Abstract: Proofs of space are a revolutionary breakthrough, allowing for the security of proof of work blockchains at a fraction of the electricity consumption. Proofs of space allows a user to prove to the network that they are storing a certain amount of data. They need to be easily verifiable, secure (resistant to attacks), and energy efficient. Chia proved with the paper “Beyond Hellman” and the Chia proof of space construction that this can be done with a process called “plotting”. We will provide an overview of the proof of space construction (plotting) and available tools.
