Smart Contracts Developer Interview Questions

A smart contract developer is a software engineer who specializes in developing smart contracts. A smart contract is a computer protocol that facilitates, verifies, or enforces the negotiation or performance of a contract. Smart contracts allow the performance of transactions and agreements to be carried out between parties without the need for a third party.The term "smart contract" was first coined by Nick Szabo in 1996. Szabo is a cryptographer who specializes in digital contracts. He realized that the decentralized nature of the internet could be used to create self-executing contracts that would be enforced by the network itself.Since then, smart contracts have been implemented on a number of blockchain platforms, including Ethereum, Bitcoin, and Hyperledger Fabric.
