DIGITAL ASSETS MANAGEMENT USING BLOCKCHAIN AND SMART CONTRACTS

There is an immense need of a Proof of Delivery (PoD) of todays digital media and content, especially those that are subject to payment. Current PoD systems are mostly centralized and heavily dependent on a Trusted Third Party (TTP) especially for payment. Such existing PoD systems often lack security, transparency and visibility, and are not highly credible, as the TTP can be subject to failure, manipulation, corruption, compromise and hacking. Blockchain is used to create a decentralized solution. Utilizing blockchain’s immutable and tamper-proof logs, accountability and auditability can be easily achieved. Ethereum which makes blockchain a programmable distributed ledger is used in our implemented solution to create a PoD solution for the digital media. The solution uses a smart contract to allow customers to request the content and be uniquely identified using Cryptographic Hash derived by Sha3 in Ethereum Blockchain. Our solution includes off-chain secure download activity involving the file server and the customers.
