Decentralized accessibility of e-commerce products through blockchain technology.

• Merging of value chain and supply chain into a single transparent blockchain-based solution. • The use of blockchain for e-commerce with the start from product development to customer acquisition. • Lattice-based cryptography usage in blockchain signcryption process. • Introduction of proof-of-accomplishment as an extension of smart contract in heterogeneous stakeholder environment. A distributed and transparent ledger system is considered for various e-commerce products including health medicines, electronics, security appliances, food products and many more to ensure technological and e-commerce sustainability. This solution, named as 'PRODCHAIN', is a generic blockchain framework with lattice-based cryptographic processes for reducing the complexity for tracing the e-commerce products. Moreover, we have introduced a rating based consensus process called Proof of Accomplishment (PoA). The solution has been analyzed and experimental studies are performed on Ethereum network. The results are discussed in terms of latency and throughput which prove the efficiency of PRODCHAIN in e-commerce products and services. The presented solution is beneficial for improving the traceability of the products ensuring the social and financial sustainability. This work will help the researchers to gain knowledge about the blockchain implications for supply chain possibilities in future developments for society. [ABSTRACT FROM AUTHOR]
