Blockchain ensures transparency, authenticity, and integrity of every transaction and is considered a breakthrough in cryptocurrency and cybersecurity due to its decentralized nature. With the growth of digital presence among mankind, cybercrime, particularly the manipulation of digital evidence in court proceedings, becomes an escalating concern. Digital evidence holds a crucial role in providing justice in court proceedings. In this work, evidence is secured using blockchain by preventing manipulation along the supply chain with chain of custody (CoC) ensuring digital trustworthiness. CoC is a continuous documentation of records as digital evidence travels from its original location to the courtroom. The Ethereum-based blockchain approach will help track data intruders and ensure the reliability of data provided during court proceedings. It allows the system participants to view evidence during court proceedings but does not allow manipulation of the evidence.
