Development costs

Introduction

In a blockchain system, developing smart contracts based on any public chain system involves the development cost of resource expenditure. For example, deploying/calling smart contracts on the network, staking/delegation and other operations all require a certain cost. Development costs vary among blockchain networks. The cost of developing smart contracts on the Alaya network is similar to that on Ethereum and similar protocols. This manual will analyze and compare the development costs in an intuitive format for users' reference.

Summary

This document will compare the development costs of small contracts, medium contracts and large contracts in the form of a table, and compare Alaya with Ethereum. A simple SET/GET contract is used as a test sample for small contracts. An open source (Eth-Tweet) contract is used as the example of medium contracts. The example for large contracts is a smart contract that complies with the ERC20 standard.
