TEE-based Smart Contracts and Sealing Pitfalls
by Andrew Miller on December 13, 2022
Last week the rest of the sgx.fail team and I posted a research preprint that
included a vulnerability disclosure affecting Secret Network. Secret Network is
the first smart contract system based on Trusted Execution Environments (TEEs)
to go live in production. However, there are several rival projects with closely
related tech that have launched public testnets, namely Oasis, Phala, and
Obscuro. Our disclosure kicked off a broader discussion, with all these projects
reaching out and/or making public statements (Phala’s), (Oasis’s), (Secret’s)
explaining to what degree they would have been affected and about the
mitigations they have in development. The four projects have been building most
independently of each other, but TEE/SGX compromise presents a common threat to
all of them, suggesting an opportunity to work together.
Atomic NFTs
by James Austgen, Kushal Babel, Phil Daian, Ari Juels, adn Mahimna Kelkar on
September 30, 2022
Atomic NFTs introduce new cryptographic techniques in order to enable NFT
creators to prevent fractionalization of their NFTs. Our work promises to give
creators stronger control over how their NFTs are bought and sold. We stress
that Atomic NFTs are a preliminary research concept. More research needs to be
done to make them truly practical. We believe, however, that practicality is on
the horizon and that Atomic NFTs could someday become a standard option in NFT
creation.
Are Non-Fungible Tokens (NFTs) Art? The Initiative for CryptoCurrencies and
Contracts Hosting an Evening of Art, Cutting Edge Research and NFTs at Roosevelt
Island Cornell Tech Art Gallery Opening Monday October 3

The Roosevelt Island Cornell Tech Tata Innovation Center is hosting The
Initiative for CryptoCurrencies and Contracts an NFT Gallery Opening on Monday

Anchored NFTs
by Ari Juels on September 26, 2022
Museums exist not just to house original works of art, but as shrines to be
visited by art lovers. Physical works of art — oil paintings, for instance —
look very different in person than in posters or digital images. I've spent
twenty minutes staring at this Vermeer in person. I can assure you that the
sacred hush magically rendered by the artist in the original painting is all but
obliterated in reproduction. There’s another facet to appreciation of art,
though, one that’s not just about brushstrokes or esthetic nuance. Why, after
all, do people flock to see the Mona Lisa when they can barely make it out
through the ten-foot thick protective barrier of tourists?
Decentralizing Databases with Basil
by Florian Suri-Payer and Natacha Crooks on August 27, 2022
Applications want to retain database functionality when decentralizing their
systems. Unfortunately, straightforward designs atop today's blockchain system
fall short of this task. The current separation between the ordering layer and
the application materialization layer in blockchain based designs precludes the
design of expressive, and high performance transactional systems. In our recent
work Basil - Breaking up BFT with ACID (transactions) we explore how to merge
these layers for improved scalability and usability.
What Are Blockchains and What Are They Good For?
by Ari Juels on July 20, 2022
Bitcoin and blockchains - the technology that makes cryptocurrencies such as
Bitcoin possible - have become inescapable phenomena in finance and even popular
culture. Despite their rise in popularity, though, there is considerable
bewilderment around blockchains and their capabilities. In this talk, Ari Juels,
the Weill Family Foundation and Joan and Stanford I. Weill Professor at Cornell
Tech and Co-Director of the Initiative for CryptoCurrencies and Contracts (IC3),
will aim to demistify this intriguing technology. He will explain how
blockchains mean much more than Bitcoin and indeed how blockchain-based digital
apes may be harbingers of our future in leisure and the arts. We hope to see you
at this virtual event.

FEATURED PROJECTS


THE IC3 NFT LICENSE


The IC3 NFT license is a copyright license specifically designed for use with
NFTs. This document describes the technical, conceptual, and doctrinal
challenges posed by NFT licensing and explains the design decisions made in
drafting a license to solve them. The license itself, which is designed to be
used in conjunction with a technical process (such as the one described in
Ethereum Improvement Proposal 5218), links a creative work to an NFT so that
when the NFT is transferred, so is the license. For further details, please
check out our Projects Page.
