CCP: Conflicts Check Protocol for Bitcoin Block Security

TL;DR

This paper introduces CCP, a conflicts check protocol that enhances Bitcoin security by detecting and resolving conflicting transactions, potentially preventing attacks through a novel arbitration mechanism.

Contribution

It proposes a new conflicts check protocol with an arbitration mechanism to improve Bitcoin transaction security and prevent conflicts-based attacks.

Findings

CCP can identify conflicting transactions effectively.

The protocol offers a new approach to Bitcoin attack prevention.

Preliminary results show promising security improvements.

Abstract

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
