Developing a smart contract system is actually the process of writing and executing code on a specific blockchain (such as Bitcoin, Ethereum, Binance Smart Chain, Tron, or Polygon (Matic)). These codes (conventions) have the ability to automatically execute and facilitate transactions without intermediaries.
The following are some popular usage rules for blockchain:
Bitcoin (BTC): Bitcoin's smart contract capabilities are relatively weak, and its scripting language is designed to be intentionally incomplete, meaning that it sacrifices some features for security and is mainly used to handle transactions.
Ethereum (ETH): Ethereum is the first public chain to provide Turing complete smart contracts. It uses Solidity or Vyper language to develop smart contracts, which can handle more complex logic and programs. It is the most commonly used smart contract platform.
Binance Smart Chain (BSC): BSC is a public chain launched by Coin Security, which is fully compatible with Ethereum and also uses Solidity as the development language. It has the characteristics of fast execution speed and low transaction costs.
Tron (TRX): Tron also supports smart contracts, mainly using Solidity as the development language, but its difference is that it uses Delegated Proof of Stack (DPOS) to replace Ethereum's Proof of Work (PoW), which makes it faster and lower transaction costs.
Polygon (Matic): Formerly known as Matic Network, Polygon is a second layer extension solution for Ethereum and a multi chain network. Like Ethereum, Polygon also uses Solidity language to write smart contracts. Its goal is to address the high transaction costs and slow speed issues of Ethereum and introduce scalability for large-scale adoption of blockchain.
To develop smart contracts on these chains, you need to understand blockchain technology, be proficient in at least one smart contract programming language, be familiar with corresponding network development tools and security specifications, and also write smart contracts that meet different business needs.
The general steps are as follows:
Learn and be proficient in programming languages for smart contracts, such as Solidity.
Use relevant IDEs or development work platforms to write smart contracts, where Remix IDE is an online development platform, and Truffle can be selected locally.
After writing, conduct unit testing, performance testing, security testing, etc. to ensure the correctness of the contract logic.
After testing without errors, deploy to the designated network through the corresponding development framework.
After running on mainnet for a period of time, observe and record the usage of the contract.
Perform contract upgrades or contract destruction operations to achieve maintenance purposes.
Ensure the normal operation of smart contracts and address potential issues.
Overall, the development of smart contracts for each chain has its own unique characteristics, but the basic principles and operating modes are the same. To become a smart contract developer, one needs to understand blockchain technology, have a deep understanding of smart contracts, and be proficient in corresponding programming languages.
