Abstract
We solve this problem by augmenting a blockchain on-chain smart contract between the sender and receiver with an off-chain cryptographic protocol, such that any significant data leakage from the receiver is penalized through a monetary loss. We develop a natural extension of oblivious transfer called doubly oblivious transfer (DOT) which, when combined with robust watermarking, a claim-or- refund blockchain contract and a non-interactive zero knowledge proof provides the necessary framework to realize the protocol in a provably secure manner.
