Blockchain technology is a foundation for a new style of trust in identity, transaction, business process and human activities. Just as the Internet provides opportunities forpermissionless innovation within the realm of communications, the mathematics and algorithms of blockchain enable the creation of new applications based on shared ledgers without permission.
The technology derives from a wide range of theories: cryptography, network, game theory, economics and law. While the research and development of blockchain is still in its early stage, fundamental research and development will help to build its social foundation.
The blockchain research team at NTT Research Inc. is conducting research to make blockchain more secure and scalable to ensure just such an outcome. We focus on security of cryptographic protocols, identity, privacy, game theory and incentive design.
