Blockchains are a new settlement and ownership layer, one that’s programmable, open, and global by default, unlocking new forms of entrepreneurship, creativity, and infrastructure. Growth in monthly active crypto addresses is generally tracking the
The economics of the internet are already changing. As the open web collapses into a prompt bar, we have to wonder: Will AI lead to an open internet or a maze of new paywalls? And who will control it — big centralized companies or broad communities
Since Nakamoto introduced the original Bitcoin protocol, a number of research works have sought to extend blockchains using advanced cryptographic technology. Much of this research has dealt with the use of (succinct) zero-knowledge to achieve privacy and scalability in blockchain protocols. Unfortunately ZK techniques have limits: they do not allow for the implementation of arbitrary computation functionalities where many parties have secret data. In this talk, Matt Green (Johns Hopkins) introduces several novel applications for blockchains, including the use of blockchains as a key ingredient in building secure computation technologies like one-time programs. Finally, Matt show how these techniques can be used to improve the security of custody technologies and to implement compliance techniques on blockchains.
