Smart contracts are applications that execute on blockchains. Today they manage billions of
dollars in value and motivate visionary plans for pervasive blockchain deployment. While …

In this whitepaper, we articulate a vision for the evolution of Chainlink beyond its initial
conception in the original Chainlink whitepaper. We foresee an increasingly expansive role …

When two or more parties need to compute a common result while safeguarding their
sensitive inputs, they use secure multiparty computation (SMC) techniques such as garbled …

Security architectures such as Intel SGX need protection against rollback attacks, where the
adversary violates the integrity of a protected application state by replaying old persistently …

User transactions on Ethereum's peer-to-peer network are at risk of being attacked. The
smart contracts building decentralized finance (DeFi) have introduced a new transaction …

We propose Tesseract, a secure real-time cryptocurrency exchange service. Existing
centralized exchange designs are vulnerable to theft of funds, while decentralized …

Blockchains such as Bitcoin and Ethereum execute payment transactions securely, but their
performance is limited by the need for global consensus. Payment networks overcome this …

Functional encryption (FE) is an extremely powerful cryptographic mechanism that lets an
authorized entity compute on encrypted data, and learn the results in the clear. However, all …

Recently there has been much academic and industrial interest in practical implementations
of zero knowledge proofs. These techniques allow a party to prove to another party that a …

Secure multiparty computation allows mutually distrusting parties to compute a function on
their private inputs such that nothing but the function output is revealed. Achieving fairness …
