Abstract
We present a server-supported, hash-based digital signature scheme. To achieve greater efficiency than current state of the art, we relax the security model somewhat. We postulate a set of design requirements, discuss some approaches and their practicality, and finally reach a forward-secure scheme with only modest trust assumptions, achieved by employing the concepts of authenticated data structures and blockchains. The concepts of blockchain authenticated data structures and the presented blockchain design could have independent value and are worth further research.
