Arrival and Welcome


KEYNOTE - A Modern History of FHE
Fully Homomorphic Encryption (FHE) is a way to compute on encrypted data without decrypting it first. We will take a journey through 16 years of techniques and advances, from the days when FHE was considered a fantasy, to the present day.

2PC-MPC: The Non-collussive, massively decentralized Multiparty ECDSA Protocol Empowering dWallets
In this lecture I'll walk through the difficulties we faced when we first imagined dWallets, and how our MPC algorithm solves each and every one of them. I will aim to explain each cryptographic building block in high-level, so that listeners should have a basic understanding of the breakthroughs we made even without reading the paper.

Distributed Randomness using Weighted VRFs
Incorporating shared randomness into blockchains enhances their versatility and security. This talk focuses on how blockchains can autonomously generate fresh randomness for each new block, particularly in proof-of-stake systems where validators have different stakes. This introduces a weighted threshold setting where authorization relies on the cumulative weight of a subset of the participants, rather than on the subset size.

We introduce three cryptographic protocols to enable generating shared randomness in a weighted setting: A publicly verifiable secret sharing scheme (PVSS) which is weighted and aggregatable, a weighted distributed key generation protocol (DKG), and a weighted verifiable unpredictable function (VUF). Importantly, in the VUF protocol, which is the protocol that is run most frequently, the computation and communication costs of participants are independent of their weight. This feature is crucial for scalability. The resulting system was implemented and deployed on the Aptos blockchain.

Panel: Technical VC Investing
In this panel, we will explore the world of venture capital investments in cutting edge research, what goes into investment decisions, how early stage research is evaluated from a venture perspective, what makes a good bet when exploring uncharted territories, and what role should investors play after investing in research.

Advances in Algebraic Ciphers
Algebraic ciphers are an efficient instrument to achieve functionalities from symmetric-key cryptography within the context of Zero-knowledge (ZK) proofs, Multiparty Computation (MPC), and Fully Homomorphic Encryption (FHE). This talk will discuss recent developments in the design and cryptanalysis of algebraic ciphers.

Panel: Research Leaders
This panel will revolve around leading a research organization within for-profit companies. Research leaders will discuss real world examples of how significant breakthroughs are made within that setting, and explore their role in balancing concrete business needs and requirements with the somewhat unpredictable nature of research.

Threshold ECDSA with Identifiable Abort: The Case for Honest Majority
Many existing MPC deployments for distributed ECDSA signing are vulnerable to denial of service attacks, and mitigation typically involves tradeoffs in cryptographic machinery and trust assumptions. In this work, we explore a mitigation approach that we argue is suitable for several applications. We construct a new honest majority ECDSA signing protocol that supports cheater identification without broadcast channels or a central coordinator

Low-Latency DAG-based consensus with Mysticeti
Less than a year after mainnet launch the Sui blockchain will be switching its consensus algorithm to Mysticeti, a new low-latency high-throughput DAG-based algorithm. In this talk we will discuss the journey of designing performant DAG based consensus algorithms, their benefits, as well as their use in production. Then, we discuss how the latest consensus algorithm, Mysticeti, integrates the best of breed techniques including simple one message-type protocols, pipelined commits, multiple leaders, and leader reputation to achieve very low-latency even under faults. Further, besides consensus, Mysticeti may be used to integrate fast-paths that finalize transactions before consensus commits, and can act as generic broadcast channels between validators.

From paper to deployment. How much the security proof of your favorite SNARK fit your use case
Presentation summary: In this talk I will discuss some crucial differences between the security models used for proving Snarks security and their applicability to snarks’ use cases.

Encryption-Based Frontrunning Protection in Shared Sequencers
This talk will explore how we can use threshold encryption techniques to protect users' transactions from frontrunning and MEV in a shared sequencer.  It will explore how the shared sequencer can coordinate decryption in a timely manner that is transparent to rollups.  It will also touch on the tradeoffs of encrypted transactions, and how we can design a system where both plaintext and encrypted transactions coexist.
