Title: Challenges in Blockchain Protocols

Ittay Eyal, Cornell

Hariri Seminar Room

Wednesday Oct 28, 10-11am


Abstract: Blockchain-based cryptocurrencies, based on Bitcoin, promise to
become the infrastructure for pseudonymous online payments, cheap
remittance, trustless digital asset exchange, and smart contracts. However,
unique security aspects form challenges that must be overcome to realize
this promise.

This talk starts with an overview of two results dealing with a key threat
on blockchains, namely centralization, where a single principal comes to
control the system. Then, it discusses the performance limits of blockchain
protocols due to their security mechanism. Finally, it presents Bitcoin-NG,
a novel Blockchain protocol that overcomes these limits.
