Catena: Efficient Non-equivocation via Bitcoin

Alin Tomescu, Srinivas Devadas
2017 2017 IEEE Symposium on Security and Privacy (SP)  
Thus, Catena logs are as hard to fork as the Bitcoin blockchain: an adversary without a large fraction of the network's computational power cannot fork Bitcoin and thus cannot fork a Catena log either.  ...  We implement Catena in Java using the bitcoinj library and use it to extend CONIKS, a recent key transparency scheme, to witness its public-key directory in the Bitcoin blockchain where it can be efficiently  ...  ACKNOWLEDGMENT We would like to thank our shepherd, Jay Lorch, and the anonymous reviewers for their insightful comments that helped improve this paper.  ...
