Honest majority is the key security assumption of Proof-of-Work (PoW) based blockchains. However, the recent 51% attacks render this assumption unrealistic in practice. In this paper, we challenge this assumption against rational miners in the PoW-ba

This paper introduces VRF-based mining, a simple and effective way of making pooled mining impossible. Instead of using hash functions, VRF-based mining uses Verifiable Random Functions (VRFs) for Proof-of-work (PoW)-based consensus. As VRF binds an

To hide user identity, blockchain-based cryptocurrencies utilize public key based coin addresses to represent users. However, the user identity can still be identified by linking the coin addresses to the IP address of a user, through network traffic

As proof-of-work blockchains are inherently energy greedy and offer probabilistic guarantees, permissioned distributed ledgers based on the classic deterministic consensus of the distributed computing literature appear as promising solutions to recor

As proof-of-work blockchains are inherently energy greedy and offer probabilistic guarantees, blockchains based on Byzantine consensus appear as a promising technology to track billions of connected devices. In this paper, we evaluate the performance
