How to start a Blockchain project?

Blockchain technology is a distributed and decentralized database that stores information securely and transparently. It consists of chronologically chained blocks of information, each block containing a transaction record. What makes blockchain technology unique is its decentralization and its ability to ensure data integrity and security without the need for a central authority.

  1. Understand the Basics: Know the basics of blockchain, how it works and its potential applications in different industries.

  2. Identify the Use Case: Determine the purpose of your blockchain project. Ask yourself how blockchain technology can solve a specific problem.

  3. Choose a Blockchain Platform: Ethereum, Hyperledger, Binance Smart Chain and many others. Each has its own characteristics and strengths. Choose the one that best suits your needs and requirements.

What is IPFS?

IPFS, which stands for InterPlanetary File System, is a protocol and network designed to create a decentralized way of sharing and storing hypermedia in a distributed file system. It was created to address some of the challenges associated with web-based file management, such as redundancy, lack of permanence and dependence on a centralized server.

Most common questions on Blockchain development in Tarragona

Creating a blockchain-based application involves several steps from planning to implementation and maintenance. Here is a summary of the process:

  1. Definition of Purpose and Objectives:
    • Identify the need or problem that the blockchain application will solve.
    • Establish clear and measurable objectives that are expected to be achieved with the application.
  2. Choice of Blockchain Platform:
    • Select the blockchain platform that best suits the project requirements (Ethereum, Hyperledger Fabric, Binance Smart Chain, etc.).
  3. Architectural Design:
    • Create an architectural design that defines the structure and components of the application.
    • Decide whether the application will be public or private and define the nodes and participants.
  4. Development of Smart Contracts:
    • Codify the smart contracts that will define the application logic and business rules.
    • Use programming languages specific to the chosen blockchain platform (Solidity for Ethereum, for example).
  5. Front-end and Back-end development:
    • Create the front-end of the application for user interaction.
    • Develop the back-end to manage application logic that is not on the blockchain.
  6. Blockchain integration:
    • Connect the front-end and back-end to the blockchain via APIs and web services.
    • Ensure the security and integrity of transactions.
  7. User Interface (UI) development:
    • Design an intuitive and attractive user interface for easy user interaction with the application.
  8. Tests:
    • Perform extensive testing to ensure the correct functioning of the application and the security of smart contracts.
  9. Implementation and Deployment:
    • Carry out the implementation and deployment of the application on the selected blockchain network.
  10. Monitoring and Maintenance:
    • Establish a monitoring system to ensure continuous performance and detection of potential problems.
    • Provide regular maintenance, updates and upgrades as needed.

This process is iterative, with continuous adjustments and improvements as feedback is obtained and the application evolves. Close collaboration between developers, blockchain specialists and stakeholders is essential to the success of the project.

A smart contract is a stand-alone computer program that automatically executes, validates or facilitates the execution of a contract when certain predefined conditions are met. These contracts are executed on a blockchain, usually on platforms such as Ethereum, Binance Smart Chain, or EOS. Here I explain the basics of what a smart contract is and how it is programmed:

What is a Smart Contract?

  1. Executable Code:
    • A smart contract is a set of executable code stored on the blockchain.
    • It is used to automate and automatically execute agreements and transactions without the need for intermediaries.
  2. Conditions of Execution:
    • Smart contracts contain logical (if-then) conditions that determine their execution.
    • For example, a contract may transfer funds to a recipient if certain conditions are met.
  3. Transparency and Security:
    • Being on the blockchain, smart contracts are transparent, immutable and secure.
    • Anyone can review the code and associated transactions.
