How do smart contracts work in crypto ?

In recent years, after the creation of Bitcoin and the launch of its first version, many interesting projects have appeared. These projects have brought new ideas and decentralized solutions to many centralized processes or applications that most investors use today. These are usually smart contracts. Find out in this article how they work.

Focus on how smart contracts work

Ethereum is currently the most used platform for smart contracts, but these are executable in many other blockchains in the cryptocurrency space (including EOS, Neo, Tezos, Tron, Polkadot and Algorand). If you want to know more about the smart contract in crypto, check out the site. The creation and deployment of a smart contract on a blockchain is accessible to everyone. Its code is transparent and publicly available, which means you can see precisely what logic the smart contract follows when it receives digital assets. Smart contracts are written in various programming languages (including Solidity, Web Assembly, and Michelson). On the Ethereum network, the code for each smart contract is stored on the blockchain. So you can look at the contract code and its current status to check how it works.

Smart contracts are stored on computers

Each computer on the network (or “node”) stores a copy of all active smart contracts and their current state, along with blockchain and transaction data. When a smart contract receives funds from a user, its code is executed by all nodes in the network to reach consensus on the outcome and the resulting stream of value. This is what allows smart contracts to operate securely without any central authority, even in complex financial transactions with unknown entities. The execution of a smart contract on the Ethereum network generally requires the payment of a fee called “gas” (so named because these fees allow the blockchain to operate). Once deployed on a blockchain, smart contracts generally cannot be modified, even by their creator. (There are exceptions to this rule, however.) This restriction helps to ensure that the contract will not be closed or censored.
