Improving the privacy, scalability, and ecological impact of blockchains
Abstract/Contents
- Abstract
- Despite the excitement around them, Blockchains today still suffer from major limitations. Popular blockchains have high transaction fees, limited privacy, and substantial ecological impact. These issues are largely due to the fact that in decentralized blockchain systems, each action performed by one party gets seen and verified by all parties in the network. In this dissertation, we develop solutions to these limitations. They rely on a common proof paradigm, in which a prover can generate a certificate that the actions it performed were in accordance with a set of rules. Importantly, the certificates can be highly efficient and privacy-preserving, even if the actions are not. We develop four such proof systems, each tailored to resolve one of the limitations of blockchains. Bulletproofs, a zero-knowledge proof system that is designed for private blockchain transactions. HyperPlonk, an efficient SNARK that enables outsourcing the processing of entire blocks of transactions. Verifiable Delay Functions, a key component for ecologically friendly blockchains, and ProtoStar, an incrementally verifiable proof system designed for building efficient Verifiable Delay Functions and succinct blockchains. These tools are not merely theoretical but have already found practical applications and are securing systems worth billions of dollars.
