Yiannis has a long-standing interest in Information- or Content-Centric Networks with several noteworthy contributions in the area. He has extensive background in several of the architectural and protocol design aspects of Information-Centric Networks having run several projects over the last decade. He sees IPFS as a deployment of ICN in the wild with a huge user-base and is therefore excited to contribute his past experience into the protocol design choices of a live network. Yiannis is active in the ICN research community and the IRTF ICNRG. In the past, he has worked in areas related to congestion control, routing, caching, naming and resource allocation of current and future fixed and mobile Internet architectures. He believes that decentralisation of Internet services will be demanded through the need to deploy services at the edge of the network, aka edge-computing. A brief thesis on this together with related works can be found here: https://www.ee.ucl.ac.uk/~ipsaras/ddec.html

Given the mass migration to remote work we’ve seen in recent months, you’d think the internet would be collapsing under the added strain. Yet precisely the opposite has happened. As experts have observed, the internet isn’t buckling under added traffic; it’s thriving.

Permissionless blockchain environments necessitate the use of a fast and attack-resilient message propagation protocol for Block and Transaction messages to keep nodes synchronised and avoid forks. We present GossipSub, a gossip-based pubsub protocol, which, in contrast to past pubsub protocols, incorporates resilience against a wide spectrum of attacks.

Resiliency is at the core of systems that are capable of standing the test of time, providing unshakable access for the many generations to come. A resilient system or network is fundamentally uncompromised by an isolated failure or network split.
