A Blockchain-based system that allows buyers and sellers to interact directly can make e-commerce platform for digital goods “cheat proof” and the products cheaper, says a study by India-origin researchers.

Blockchains allow multiple stakeholders to transact money or data virtually over linked peer-to-peer computer networks.

Besides Blockchain, their proposed solution involves “smart contracts” and game theory.

“Our scheme offers potentially a big improvement over the state-of-the-art in electronic commerce because it allows buyers and sellers to interact directly with each other without the need for third-party mediators of any kind,” said Bhaskar Krishnamachari, Professor at Viterbi School of Engineering, University of Southern California, the US.

“It uses a dual-deposit method, escrowing a safety deposit from both buyer and seller that is returned to them only when they behave honestly. And the verification of who is at fault and who is honest is done automatically by the smart contract,” added Krishnamachari.

This “smart contract” stores a good’s digital hash code or “digital fingerprint”.
