What is a dapp blockchain?

A DApp, or Decentralized Application, is a type of application that runs on a blockchain network. Unlike traditional applications, DApps do not rely on a single centralized server, but use blockchain technology to decentralize their structure and operation.

  1. Decentralization: DApps operate on a decentralized network of blockchain nodes, meaning there is no single point of control or failure. This increases resistance to censorship and improves security.

  2. Smart Contracts: DApps often use smart contracts, which are self-executing programs with built-in rules and logic. These contracts are automatically executed when certain conditions are met, without the need for intermediaries.

  3. Immutable Record: The information on the blockchain is immutable, meaning that once a block of data is added to the chain, it cannot be modified or deleted. This provides a transparent and verifiable history of all transactions.

What is a Smart Contract?

A Smart Contract or smart contract is a self-executing computer program designed to facilitate, verify or enforce the negotiation or execution of a contract on blockchain.

Smart Contracts are written in specific programming languages and run on a blockchain platform such as Ethereum, which pioneered the implementation of this technology. The key feature of a Smart Contract is its ability to execute automatically when certain predefined conditions are met. This eliminates the need for intermediaries and reduces fraud risks, as contract execution is based on the code and transparency of the blockchain.

Most common questions about Blockchain development in Zaragoza

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.
