Igor Pejic brings the blockchain to the boardroom

It reveals how the trust machine that fueled the rise of bitcoin and other crypto coins will drive a new economy.

Big Tech is about to rewire the global financial system at a scale and pace never seen before. It is imperative that incumbents and challengers understand the new nature of their competitive advantage.

Big Tech in Finance provides a cutting-edge look at tech titans’ play for domination of the blockchain economy, its ramifications, and how finance is fighting back. The book examines the motives behind Big Tech's break into banking and unpicks the strategies behind the use of distributed ledgers, technology interfaces, infrastructure and investments into crypto unicorns. It then goes on to review how commercial and central banks counter those threats by driving their own centralized blockchain strategies.

Delving into the fight between Big Tech, Big Banking, Big Government, and disruptive start-ups, Igor Pejic analyzes which actors have the best shot at succeeding. He explores the key tools in play, such as smart contracts, digital central bank currencies, decentralized finance (DeFi), decentralized autonomous organizations (DAOs) and Web3. Big Tech in Finance also divulges the geopolitical dimensions underpinning the power struggle and its implications for the industry. Written by an internationally recognized expert on blockchain, the book draws on in-depth interviews with founders, investors, regulators, bankers, and tech experts to provide valuable insider knowledge. This is an essential read for finance and fintech professionals, bankers and investors, and anyone else interested in the future of money.
