This conference focuses on technical innovations in the blockchain ecosystem, and brings together researchers and practioners working in the space. We are interested in the application of cryptography, decentralized protocols, formal methods, and empirical analysis, to improving the security and scalability of blockchain deployments. We aim to foster collaboration among practitioners and researchers working on blockchain protocol development, cryptography, distributed systems, secure computing, crypto-economics, and economic risk analysis.

Join us for the 8th Annual IC3 Blockchain Camp! This 7-day experience will be hosted for the first time on the Cornell Tech Campus on Roosevelt Island in New York, NY.

Cornell FinTech Club (CFT), the first all-encompassing fintech club for undergraduates at Cornell University, is hosting a blockchain hackathon (NFTs and more) from April 29 to May 1, 2022 sponsored by Ava Labs, Fintech at Cornell, and The Initiative for CryptoCurrencies and Contracts (IC3). This hackathon aims to inspire participants to create blockchain innovations by introducing fintech concepts and developing with Avalanche, Ava Labs' smart contracts blockchain platform. Attendees can mentor, judge, or host/speak at a workshop/event and Cornell undergraduate students only can hack in teams for prizes. With workshops, a $6k+ prize pool, multiple challenges, food, swag, social and corporate events, attendees and hackers will experience a fun, innovative weekend. Want to attend or hack at the 2022 Cornell FinTech Club Avalanche Hackathon? Please fill out this interest form.

The attempt to modernize oversight of America's financial markets and the simultaneous rise of bitcoin, cryptocurrencies, and the digital dollar are disrupting financial services as we know them. This roundtable will examine the potential for crypto/blockchain networks to transform the financial sector and what that means for consumers and institutions.

The goal of this event is to introduce Protocol Labs Research's newly formed ConsensusLab to its future partners and to establish a workshop-style venue to bottstrap scientific exchange across a wider community of shared interests. We invite contributions from current and prospective collaborators, as well as from all researchers in the field.

Cryptocurrencies do not scale. In this technical deep-dive, we provide an overview of an alternative scaling approach, off-chain protocols, that lets parties transact locally amongst themselves instead of the global network. Off-chain is remarkable as in the best case it lets parties bypass all network fees and blockchain latency, and in the worst-case, the parent blockchainsafeguards the funds of all honest parties. We'll cover the two leading approaches, channel-based networks (lightning et al) and commit-chains (plasma & rollup et al) alongside the new the always online assumption and how the community is trying to alleviate it. If we, as a community, can pull off the implementation of off-chain protocols, it will hopefully unleash a truly permissionless, global and internet-scale financial system.

Applications include insurance contracts that protect consumer privacy, systems to trade online resources such as games for cryptocurrency, and much more.
