What is a smart contract in Blockchain?

A smart contract is a self-executing contract with the terms of the agreement between buyer and seller being directly written into lines of code. The code and the agreements contained therein exist across a distributed, decentralized blockchain network.

Are smart contracts legal?

A smart contract is computer code that can automatically monitor, execute and enforce a legal agreement. Legally, the early interpretation of smart contracts reduced the smart contract to the sole code, effectively declaring the code as the law itself: self-contained, self-performed and self-enforced.

How smart contracts are executed?

The concept of smart contracts was proposed by Nick Szabo, an American computer scientist and researcher of digital currencies, in 1994. The smart contract is executed through a blockchain network, and the code of the contract is replicated on many computers that comprise the network.

How smart are smart contracts?

Smart contracts can be created on blockchains such as Ethereum which currently dominates in terms of adoption rates of the technology. The autonomous nature of smart contracts means you can expect huge improvements on traditional systems in terms of speed, cost, security, accuracy and transparency.

How does a smart contract look like?

A smart contract is an agreement between two people in the form of computer code. They run on the blockchain, so they are stored on a public database and cannot be changed. The transactions only happen when the conditions in the agreement are met — there is no third party, so there are no issues with trust.

What is the point of smart contracts?

Smart Contracts: The Blockchain Technology That Will Replace Lawyers. TLDR: A smart contract is a computer protocol intended to digitally facilitate, verify, or enforce the negotiation or performance of a contract. Smart contracts allow the performance of credible transactions without third parties.

Can smart contracts be changed?

Smart contracts in Ethereum are immutable by default. Once you create them there is no way to alter them, effectively acting as an unbreakable contract among participants.
