Cryptographic Resilience
within Ethereum
at Devconnect 2023
Workshop on cryptographic resilience
within Ethereum
Ethereum is increasingly reliant on cryptography. To date we are actively using hash functions, EC-DSA signatures, BLS signatures, and we will be using polynomial commitments after the Cancun-Deneb upgrade.
This workshop highlights the current and future suggestions for cryptographic uses and questions how best to ensure Ethereum remains resilient to cryptographic attacks. We will cover a large spectrum of topics, such as quantum resilience, long term privacy assurance, threshold cryptography and fuzzing mindsets. We will hear from top researchers and practitioners both inside and outside of the Ethereum ecosystem.
General Registration
Registration for general participants is €25. Although our intention was to offer this event for free, advice from experience suggests a minimal fee helps ensure committed participation. We humbly request your cooperation in this regard. Please register for the event only if you are certain about attending.
Eligibility for Fee Waiver:
If the registration fee poses a genuine financial hardship, please don't hesitate to request assistance. We encourage students, early-career researchers, and individuals from low-resourced institutions or regions to apply. Please email cryptography@ethereum.org with the subject line FEE WAIVER REQUEST DEVCONNECT 2023 to request a fee waiver. We'll review submissions on a case-by-case basis, with the intent of supporting those who need it most.
