CCP: Conflicts Check Protocol for Bitcoin Block Security
This addresses security issues in Bitcoin, potentially extending attack analysis and prevention, but appears incremental as it refines existing systems.
The authors tackled the problem of preventing potential attacks on the Bitcoin system by proposing a Conflicts Check Protocol (CCP), which introduces a novel arbitration mechanism to approve or abandon conflicting transactions, based on observed common symptoms of attacks.
In this work, we present our early stage results on a Conflicts Check Protocol (CCP) that enables preventing potential attacks on bitcoin system. Based on the observation and discovery of a common symptom that many attacks may generate, CCP refines the current bitcoin systems by proposing a novel arbitration mechanism that is capable to determine the approval or abandon of certain transactions involved in confliction. This work examines the security issue of bitcoin from a new perspective, which may extend to a larger scope of attack analysis and prevention
