Bounties for breaking RSA Assumptions
For more explanation on the assumptions, please see RSA assumptions.
To improve the cryptanalysis of new RSA assumptions needed for Verifiable Delay Functions (VDFs), the Ethereum Foundation announced the following bounties at Real World Crypto 2020:
A bounty of $10,000 will be given for:
- An algorithm that solves the Adaptive Root Problem in an RSA group asymptotically faster than the fastest known algorithm for factoring an RSA number.1
- Reducing the Adaptive Root Assumption to one of these assumptions: Strong RSA Assumption, RSA Assumption, Diffie-Hellman Assumption, or proving the Adaptive Root Assumption is (non-)equivalent to Factoring in the Generic Ring Model.
- The most interesting paper published on the Adaptive Root Assumption published in 2020. 2
- Other unknown reductions from the Adaptive Root Assumption or the Low Order Assumption to one of the other assumptions listed here.
- Five prizes for high quality papers on either the Low Order Assumption or the Adaptive Root Assumption published in 2020. 3
For more details on the assumptions, see here: RSA Assumptions.
Bounties for solving the RSA adaptive root problem in concrete RSA groups have been instantiated on an Ethereum smart contract:
