Smart Contract is a code that executes in a blockchain node and works independently.

You can develop a smart contract in the following languages.

  • Solidity
  • Viper
  • Rust
  • ivy-lang

Smart Contract features:

  • Decentralized: The code executes in blockchain nodes. So It runs in decentralized nodes
  • Independent: Executes independently

Smart Contract Advantages:

  • Secured data with blockchain protocols
  • Data will not be lost as it saves a copy of data in multiple nodes in the blockchain network
  • Automatically do what it wants to do

Disadvantages:

  • Contract code and data is immutable, Once the contract is deployed, Changes to the contract is difficult and maintenance is difficult

SmartContract Tools:

  • TestNet for testing contract code in the fake blockchain network
