Proof-of-Prestige: A Useful Work Reward System for Unverifiable Tasks [article]

Michał Król, Alberto Sonnino, Mustafa Al-Bassam, Argyrios Tasiopoulos, Ioannis Psaras
2019 arXiv   pre-print
In order to deal with such cases, we design Proof-of-Prestige (PoP) - a reward system that can run on top of Proof-of-Stake blockchains.  ...  PoP is resistant against Sybil and Collude attacks and can be used to reward workers for completing unverifiable tasks, while keeping the system free for the end-users.  ...  CONCLUSION We presented Proof-of-Prestige (PoP)-a reward system that can run on top of any Proof-of-Stake blockchain.  ...

Reputation-Based Trust Approaches in Named Data Networking

Ioanna Angeliki Kapetanidou, Christos-Alexandros Sarros, Vassilis Tsaoussidis
2019 Future Internet  
In this paper, we provide an overview of reputation-based trust approaches, present their design trade-offs and argue that these approaches can consolidate NDN trust and security by working complementary  ...  Blockchain-based solutions can be used in this case, such as Proof-of-Prestige [47] which forms a reward system for unverifiable tasks.  ...  A prominent example of a reputation-based system implementation is electronic commerce.  ...
