Blockchains are under constant security threat from hackers and other agents. Adam Koltun, Lead Business Strategist for the Quantum Resistant Ledger, is a part of one of the projects looking at the intersection between blockchain and quantum computing. He will discuss the necessary evolution of signature schemes to keep blockchain technology safe and open as new security threats arise. In this talk, he will discuss the basics of quantum computing (bits vs qubits etc.), the limitations of quantum computing, and how/where it intersects with blockchain technology. As cryptocurrencies continue to rise in prevalence, security is of the utmost importance. Quantum computing poses a direct threat to the signature schemes of blockchain networks. Adam will present the impact of quantum computing on blockchain technology and the necessary security features to protect blockchains from quantum computers. As Adam explores the central question of what makes a signature scheme quantum resistant, he will discuss such topics as One Time Signatures(OTS), the Extended Merkle Signature Scheme (XMSS), as well as other emerging best practices in the journey towards quantum resistance.
