Smart contract an how to use it ?

[Caitsith]

I have read some articles about a smart contract but it is only on the theory, i still don't know how and where i can create some smart contract .

Me too, read the theory, not understand its use and how to create the real account in the contract smart.

Please concrete your questions. What do you want to know about smart contracts? What didnt you understand when reading about them? Did you use google to get answers to your questions?

I am also researching and reading information about smart contracts. I just know smart contracts can be used in many cases, from financial services, healthcare to insurance. As for the use, I also do not know.

Bitcoin doesnt have smart contracts yet.
I think ethereum have and it need special software that allows you to make contract.

Bitcoin has a smart contract but you have to know programming language.

It only happens when you make a transaction that distances geographically, the smart contract shortens the signing time and the transaction.

I think this SMART CONTRACTS, simply explained... thread which i posted will helps to anyone who looking for explanations and its usages.

BTCitcoin aslo supports "Smart Contracts" although a lot more limited when compared with Ethereum.

I think you must learn Ethereum because the goal of Ethereum is to be a platform that can run smart contracts and decentralized applications in it.

this articles help me understand it clearly, thanks a lot.

You can run solidity, truffle, etc. in your computer or VPS with commandline or you can install MetaMask and work in browser: https://metamask.io/ https://remix.ethereum.org/
Always use testnet or testrpc to develop smart contracts (free). Only use mainnet (costs ETH) when you are sure your smart contract is complete, functional and ready to publish.

Vitalik Buterin, explained:
“In a smart contract approach, an asset or currency is transferred into a program and the program runs this code and at some point it automatically validates a condition and it automatically determines whether the asset should go to one person or back to the other person, or whether it should be immediately refunded to the person who sent it or some combination thereof.”

Smart contracts essentially define and enforce rules and penalties for a mutual exchange or transaction within seconds in an automated manner. The document is also stored in the distributed public ledger which is the main point of contact. Ethereum charges a transaction fee in Ethers for every transaction. Say for a transfer for 50000 you will be charged a transaction cost of 0.002 ETH which is a lot. One of the blockchain protocols XDC that i recently read about has very low transaction cost as it doesn't use an external process called gas for mining the blocks. Also the standard use of ERC20 ensures fundamental compatibility with the multitude of emerging Ethereum Dapps. But what is amazing is that unlike Ethereum wallets, XDC tokens call on tokens's contact rather than sending them from a wallet, preventing loss of tokens.

Smart ones have a wide range of possible use cases - for businesses, individuals and for IoT devices themselves. In an industry, such as the music industry, either the artist themselves or a publishing company own the rights to the content put out.A smart contract solution here, built on a blockchain, would keep track of all ownership rights. Trusted in true trust - as any changes to the data on the blockchain requires a consensus from all parties on the network.

You can make contracts using Ethereum cryptocurrency, but it requires special software that will allow you to make contracts.

[Trililing]

Me too, read the theory, not understand its use and how to create the real account in the contract smart.

First lesson:
Smart contracts runs on the blockchain.

Second:.
Smart contracts lets you pay using almost all cryptocurrencies.

Ethereum's ERC-20 smart contracts are the easiest to work with.

They provide a self help guide to get started:
