Smart contracts get executed by the blockchain nodes, as a result of processing transactions that are submitted by the user. A blockchain transaction has a designated target smart contract function, a payload that contains input values to the function call, and always signed by the submitter.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.

How are smart contracts written?
Smart contracts work by following simple “if/when…then…” statements that are written into code on a blockchain. A network of computers executes the actions when predetermined conditions have been met and verified.

Who write smart contracts?
Smart contracts were first proposed in 1994 by Nick Szabo, an American computer scientist who invented a virtual currency called “Bit Gold” in 1998, fully 10 years before the invention of bitcoin. In fact, Szabo is often rumored to be the real Satoshi Nakamoto, the anonymous inventor of bitcoin, which he has denied.

How are smart contracts enforced?
A smart contract is a self-enforcing agreement embedded in computer code managed by a blockchain. The code contains a set of rules under which the parties of that smart contract agree to interact with each other. If and when the predefined rules are met, the agreement is automatically enforced.
What are smart contracts for dummies?
