League of Identity

We describe a method for sending crypto assets to email addresses, Facebook accounts, telephone numbers etc. without prior communication between the sender and recipient. This has potentially ground-breaking implications for the facilitation of web3 onboarding.

Indistinguishability obfuscation (iO) for general circuits

We propose a construction for indistinguishability obfuscation (iO) for general circuits. The scheme is concocted from four main ingredients: (1) selectively indistinguishably-secure functional encryption for general circuits having its encryption procedure in complexity class NC1; (2) universal circuits; (3) puncturable pseudorandom functions having evaluation in NC1; (4) indistinguishably-secure affine-determinant programs, a notion proposed by works in submission that particularizes iO for specific circuit classes and acts as 'depleted' obfuscators. The scheme can be used to build iO for all polynomial-sized circuits in a simplified way. Instantiations can be obtained from sub-exponentially secure learning with errors (LWE).

TLCS protocols for time-locked encryption

We describe two protocols (zk-TLCS and TLCS) that can be used for time-locked encryption under the assumption that a trusted parts publishes a certain type of random beacon at regular intervals. We then present our *timelock.zone* service, which will be based on the TLCS protocol.

Fast Consensus in Weakly Byzantine Asynchronous Environments

We explore conditions for achieving binary consensus in a single communication step when conditions are favourable. With leader-based protocols and known block producers this is possible with only a slight weakening of fault tolerance assumptions.

The Poseidon hash function and its implementation in Noir

In this blog post, we provide a brief description of the Poseidon hash function, which provides a contrast with the SHA-2 family of hash functions discussed in a previous post, and discuss its implementation in Aztec's Noir language.
