Work Description

The goal of this PhD research is to investigate possibility of integrating additional cryptographic concepts that are not yet present in the existing blockchain technologies and services, but has been developed by cryptographers for many years. 

The concept of blockchain has energized the global financial industry and its services. A blockchain is a public ledger of all electronic transactions that have ever been executed. The first globally successful implementation of the blockchain concept was the cryptocurrency Bitcoin. It uses in a clever way the cryptographic concepts of one-way functions, public keys, Merkle trees and the proof-of-work concept. Afterwards, several new alternative cryptocurrencies have been proposed such as Ethereum, Zerocoin, Ripple and many others. In addition to the cryptographic concepts that are used in Bitcoin, they introduced a use of additional cryptographic structures and concepts such as new binary trees, cryptographic zero-knowledge proofs, proof-of-the-stake (to name a few). Cryptography as a mature scientific discipline in the past 40 years has developed many other concepts such as multi-party computations, hommomorphic encryption, incremental cryptography, post-quantum cryptography, identity based encryption, indistinguishability obfuscation, and many others.
