Thesis

Dual Wallet Authentication on Smart Contract Blockchain Using Node.js & JWT

A novel architecture combining two blockchain wallet addresses as a dual-factor identity layer, secured by JWT tokens from a Node.js backend. Smart contracts on Ethereum enforce wallet ownership on-chain, while JWT handles off-chain session management — a hybrid Web2/Web3 security model.
