Visa Research, Palo Alto, CA
The Digital Currency Research team at Visa Research is looking for outstanding research interns as part of our growing team in Palo Alto, California.
Our team is building the next generation of financial systems that rely on digital currencies, including decentralized cryptocurrencies like Bitcoin and Ethereum and semi-decentralized digital currencies like stablecoins, central bank digital currencies (CBDCs), and tokenized commercial bank deposits. Compared to traditional financial systems, these networks have significantly stronger resilience against cyberattacks, achieved by minimizing trust in various system components.
Past intern projects have included:
- Blockchain scalability, e.g., sharding (RapidChain) and light clients (FlyClient)
- Layer 2 scalability solutions, e.g., hub-based payment channels (UPC) and offline payments (OPS)
- Blockchain privacy, e.g., private smart contract transactions (Zether)
- Privacy-preserving auditability of large payment graphs (SPA)
- Privacy-preserving fraud detection using federated learning and multi-party computation
Basic Qualification
- Pursuing a Ph.D. in Computer Science or Computer Engineering, graduating December 2023 or later
Preferred Qualifications
- Research experience in one or more research areas related to blockchain, cryptography, and/or systems security
- Strong track record in research publications and impact in the research community
- Strong ability to collaborate
- Good team player and excellent interpersonal skills
- Good analytical and problem-solving skills

Meta, Menlo Park, CA, USA
Challenges and intern projects include incorporating approaches such as multi-party computation, homomorphic encryption, trusted execution environments, differential privacy, and federated learning to develop privacy-focused solutions while maintaining performance at massive scale, including cryptographic protocols, algorithms & tooling for machine learning or analytics. Research projects may include developing new or improving existing privacy-preserving solutions for areas such as: private record linkage, privacy-preserving ML and analytics.

Homomorphic Sortition relies on Threshold Fully Homomorphic Encryption (ThFHE) and is tailored to proof-of-stake (PoS) blockchains, with several important optimizations with respect to prior proposals. In particular, unlike most existing SSLE protocols, it works with arbitrary stake distributions and does not require a user with multiple coins to be registered multiple times. Our protocol is highly parallelizable and can be run completely off-chain after setup.
Some blockchains require a sequence of rounds to have non-repeating leaders. We define a generalization of SSLE, called Secret Leader Permutation (SLP) in which the application can choose how many non-repeating leaders should be output in a sequence of rounds and we show how Homomorphic Sortition also solves this problem.

The context motivating this design is the recursive verification of STARKs. This context imposes particular design constraints, and therefore the hash function's arithmetization is discussed at length.
