What is a Smart Contract?
A smart contract is a digital contract that automatically carries out the rules of the agreement. It is a computer program that automatically executes, enforces, or helps negotiate and carry out a contract when certain conditions or triggers are met. Smart contracts are often used with blockchain technology but can also be used with other distributed ledger technologies or even with standard computer systems.
How does Stellar work?
Stellar is a blockchain-based tool that makes it easy and safe to send money across borders and issue assets. It runs on a decentralized network of nodes and uses the Stellar Agreement Protocol (SCP), a unique way to reach an agreement. Here is a quick summary of how Stellar works:
1. Stellar works on a network of nodes in different places. Stellar is an open and welcoming system because anyone can run a node.
2. Ledger: Stellar keeps track of all activities and account balances on the network in a public ledger called the Stellar Ledger. All of the nodes that are taking part share the record.
3. Accounts and Assets: Stellar accounts are like bank accounts identified by unique public keys. On the Stellar network, users can hold and handle different kinds of assets, such as cryptocurrencies like XLM (Stellar Lumens) and custom tokens made on the Stellar platform.
4. Transactions: On the Stellar network, transactions involve moving assets from one account to another. Stellar can handle many different types of transactions, such as payments, offers (limit orders), and more complicated operations for issuing and managing assets.
5. Stellar Consensus Protocol (SCP): The SCP is how Stellar ensures everyone agrees on something. Unlike standard proof-of-work (PoW) or proof-of-stake (PoS) systems, SCP doesn't need miners or validators to solve difficult puzzles or stake tokens. Instead, SCP uses a federated Byzantine agreement method to make decisions.
6. Anchors: Anchors are entities, like banks or other financial institutions, that connect the Stellar network to traditional banking systems. On the Stellar network, they give tokens representing assets like foreign currencies or commodities. Anchors are places where users can put real-world goods and get tokens of the same value on the Stellar network.
7. Path Payments: The path payments feature of Stellar lets users send assets across borders by finding the fastest way through a network of trust lines and assets. During a cross-border transaction, the network automatically converts assets. This makes cross-border operations faster and less expensive.
8. Inflation Mechanism: Stellar can make more XLM tokens available to people who already own them. This system encourages people to join the network and help XLM be shared fairly.
9. Smart Contracts (Stellar Smart Contracts, or SSC): Stellar's main goal is to make payments and asset sales easier, but its SSC language does allow simple smart contracts. SSC lets writers make simple transaction scripts and conditions.
10. Wallets and platforms: People use wallets and easy-to-use platforms to talk to the Stellar network. With these tools, users can make and handle accounts, send and receive payments, and trade assets on the Stellar decentralized exchange.
What is Soroban?
An ancient Japanese abacus called a Soroban has been used to do math for hundreds of years. It has a rectangular frame with rods or lines running horizontally and beads that can move up and down on each rod. Similar to the digits in our base-10 decimal system, the amount and placement of beads on each rod show the place value.
To make Stellar smart contracts, you must write custom code that tells the Stellar blockchain when certain conditions are met and what steps to take. Stellar uses a code called "Stellar Smart Contract," or SSC. SSC is a simple language for building smart contracts on the Stellar network.
Here are the steps you need to take to make a Stellar smart contract:
1. Learn the basics of Stellar: Before you start making smart contracts, you must know much about how Stellar works. Learn about Stellar's most important ideas, like assets, accounts, transactions, and the Stellar Consensus Protocol (SCP).
2. Set up a Stellar development environment: It would be best to have a development environment to make, test, and use smart contracts. You can set up a Stellar programming environment using Stellar SDKs and tools like Stellar Laboratory.
3. Write the code for your smart contract: Stellar smart contracts are usually written in SSC, which stands for Stellar Smart Contract.
4. Compile and deploy: You must turn your SSC code into a file Stellar can understand. You can do this with the SSC assembler from Stellar. Once you've generated the code, you can send the smart contract to the Stellar network. Most of the time, this is done with the Stellar Laboratory or Stellar SDKs.
5. Test Your Smart Contract: Before putting your smart contract on the main Stellar network, you should ensure it works as planned by testing it on the Stellar testnet.
6. Deploy to Mainnet: Once you know your smart contract works properly, you can send it to the main Stellar network. Be aware that this may involve other things to think about, such as handling the contract's lifecycle and ensuring it is safe.
7. Monitor and maintain: Once the smart contract is in place, you should monitor how it works and make changes or updates as required.
Please keep in mind that this is just a simplified overview. The actual development process can be more complicated based on your needs. Also, SSC is a limited and relatively simple scripting language, so complicated smart contracts may need careful design and planning.
Always be careful when working with smart contracts on a live blockchain, especially when dealing with real assets, because mistakes can lead to permanent financial losses. Before putting a smart contract on the main net, it's a good idea to get help from experienced blockchain developers and try it thoroughly.
How to create Stellar Smart Contracts using Soroban
Here are the steps to create a smart contract on Stellar using Soroban:
Creating Stellar Smart Contracts using a Soroban, a physical counting tool, would be impractical and unfeasible. Smart contracts in the context of Stellar are digital programs that run on the Stellar blockchain. They involve writing code in the Stellar Smart Contract (SSC) language and deploying it to the Stellar network. On the other hand, the Soroban is a manual counting device and has no relevance to writing or executing code.
To create Stellar Smart Contracts, you must follow digital steps, not physical ones. Here are the correct steps:
1. Learn about Stellar and Smart Contracts: Start by understanding how Stellar works, its consensus mechanism (Stellar Consensus Protocol), and the basics of creating smart contracts on the Stellar network.
2. Set Up a Development Environment: Prepare your development environment by installing the necessary tools and software for writing, compiling, and deploying Stellar Smart Contracts. You'll need access to a code editor, the Stellar Development Kit (SDK), and the Stellar Laboratory for testing.
3. Write Your Smart Contract Code: Use the Stellar Smart Contract (SSC) language to write your smart contract code. Define the conditions and actions your contract should perform when certain triggers are met. SSC is a specialized language for creating smart contracts on the Stellar network.
4. Compile Your Code: After writing the code, compile it into a format that the Stellar network can understand. You can use the SSC compiler provided by Stellar for this purpose.
5. Test on the Stellar Testnet: Before deploying your smart contract on the main Stellar network, it must be tested thoroughly on the Stellar testnet. This allows you to identify and fix any issues or vulnerabilities in your contract.
6. Deploy to the Mainnet: Once you are confident that your smart contract works as expected, you can deploy it to the main Stellar network. Deploying on the mainnet involves submitting the contract to the network and paying the associated transaction fees.
7. Monitor and Maintain: After deployment, you should continuously monitor the performance of your smart contract and make any necessary updates or modifications as needed.
Creating Stellar Smart Contracts involves writing and deploying digital code, not using a physical counting tool like the Soroban. The Soroban is a valuable tool for manual calculations but is irrelevant to blockchain-based smart contract development.
Using a Soroban, a physical tool for counting, to make Stellar Smart Contracts would be very difficult and impossible. In the context of Stellar, smart contracts are computer programs that run on the Stellar blockchain. They involve writing code in the Stellar Smart Contract (SSC) language and putting it on the Stellar network. On the other hand, the Soroban is a human counter that has nothing to do with writing or running code.
To make Stellar Smart Contracts, you must take digital steps, not physical ones. Here's how to do it right:
1. Learn about Stellar and Smart Contracts: Start by getting a good idea of how Stellar works, its consensus mechanism (the Stellar Consensus Protocol), and the basics of making smart contracts on the Stellar network.
2. Set up a development environment: Set up your development environment by installing the tools and apps you'll need to write, compile, and use Stellar Smart Contracts. You'll need a code editor, Stellar Development Kit (SDK), and Stellar Laboratory for testing.
3. Write Your Smart Contract Code: Use the Stellar Smart Contract (SSC) language to write your smart contract code. Define the conditions and steps your contract should take when certain triggers happen. SSC is a specific language for writing smart contracts on the Stellar network.
4. Compile Your Code: After you write the code, you need to compile it into a file that the Stellar network can understand. For this, you can use the SSC translator that Stellar gives you.
5. Test on the Stellar Testnet: Before putting your smart contract on the main Stellar network, you must test it fully on the Stellar Testnet. This lets you find any problems or weak spots in your contract and fix them.
6. Deploy to the Mainnet: Once you are sure your smart contract works as expected, you can send it to the main Stellar network. To put a contract on the main net, you must send it to the network and pay the transaction fees.
7. Monitor and maintain: Once your smart contract is up and running, you should monitor how it's doing and make any updates or changes as required.
In short, you can't use a physical counting tool like the Soroban to make Stellar Smart Contracts. Instead, you have to write and release digital code. The Soroban is a useful tool for doing math by hand, but it has nothing to do with building smart contracts on the blockchain.
Conclusion
Stellar (XLM) fans were very excited to hear what Soroban had to say. This tool could give the network new uses and make people more likely to use it. It could also allow it to compete with other big blockchains, like Ethereum. Stellar's goal for smart contracts is to give people a platform that is easy to use, friendly to users, and scalable. According to the team behind the project, Soroban could become the standard smart contract platform in the crypto business.
