What is Blockchain technology?

Blockchain technology is a decentralized and distributed system of record that enables secure and transparent transactions without the need for intermediaries. It is the underlying technology behind cryptocurrencies such as Bitcoin, but its application goes beyond financial transactions.

Instead of storing information in a single central location or server, the blockchain distributes data across a network of interconnected computers (nodes). Each node in the network has a complete copy of the log, known as a ledger. When a transaction is performed, it is grouped with others in a block. Before being added to the chain, the block must be verified by the majority of nodes in the network, through a process called consensus.

Most common questions about Blockchain development in Valencia

Metlabs with +5 years of experience, based in Valencia, has worked for blockchain development and programming projects in: Paterna, Torrent, Gandía, Sagunto, Mislata, Alzira, Burjassot, Ontinyent, Xirivella.

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.
