Code Optimization Strategies for Reducing Gas Costs in a Smart Contract Student Paper

Smart contracts are computer programs that are executed on blockchain network. Executing smart contracts requires a certain cost. Costs are measured by the amount of gas. One of the important goals in the smart contract development process is to create it in a way that minimizes gas costs. In addition to cost, an excess of gas negatively impacts code performance and security. Until transactions are executed, the total gas cost cannot be accurately predicted in advance. Calculating the gas cost for transactions alone does not provide sufficient data to reveal the source of high costs. However, there are various tips and strategies in creating smart contracts that can help save on gas costs. The focus of this paper will be on presenting specific code modification activities aimed at reducing gas costs.
