Quantum-Proofing the Blockchain

Report Overview

Author: Vlad Gheorghui, Sergey Gorbunov, Michele Mosca, Bill Munson
Release Date: November 23, 2017

Abstract:

This project examines the quantum threat to blockchain technology, with its heavy reliance on public-key cryptography. It underscores the urgent need for quantum-resistant algorithms, international standards for cryptosystems, and a large-scale retooling of information and communications technology infrastructure worldwide. The authors distinguish types of quantum adversaries and analyze our options—from patching methods to building quantum-resistant blockchains from scratch.

Digital Asset Revolution

In this white paper, “Digital Asset Revolution: The Rise of DeFi and the Reinvention of Financial Services,” Alex Tapscott explores the disruptive effects of decentralized finance (DeFi) applications on the nine functions that Wall Street currently performs. He also examines the creation and use of nine cryptoassets such as non-fungible tokens, stablecoins, DeFi index funds, synthetic securities, and central bank digital currencies. Finally, Alex discusses Web 3 innovations with Layer 1 and Layer 2 solutions to such implementation challenges as scalability, interoperability, and ease of use. If bitcoin was the spark for the financial services revolution, then DeFi and digital assets are the accelerant. This is a must-read for leaders who want to understand how blockchain will transform every aspect of the global economy.

State of Enterprise Blockchain: A Mid-Year Review

This project reports on the state of the enterprise blockchain space. It begins with commentary on the state of the world writ large—from the pandemic’s effects on the economy and the global need for vaccinations to the K-shaped recovery and the consequences of helicopter money (e.g., inflation). It covers a series of developments relevant to enterprise users: the price volatility of cryptocurrencies, the shortcomings of consensus mechanisms for enterprise needs, the growth of stablecoins, the status of tokenless blockchains and blockchain-as-a-service offerings, and the latest on central bank digital currencies (e.g., China’s digital currency electronic payment initiative). It concludes with a summary of implementation challenges that enterprise applications must overcome to gain traction. It’s time for blockchain innovators to address enterprise leaders’ tough questions about use cases, regulation, criminal usage, and environmental harm.
