Blockchain is a technology that enables the distributed, secure and verifiable recording and storage of data. Its application extends to multiple sectors, including those related to digital assets and information management.
This section provides a general description of what blockchain technology is and how it operates.
Definition of Blockchain
Blockchain, or distributed ledger, is a distributed data storage system that records transactions in cryptographically linked blocks. Each block contains information about the transactions carried out, a reference to the previous block and a timestamp, which contributes to making the data verifiable and resistant to modification.
Blockchain may be compared to a distributed digital ledger …
Main characteristics of blockchain
Decentralisation: There is no central entity controlling the data; information is stored across a distributed network of nodes.
Security and transparency: Transactions are recorded in a verifiable manner, which may reduce certain operational risks.
Immutability: Once recorded, data cannot be modified or deleted, ensuring its authenticity.
Smart Contracts: Programs that execute automatically when certain conditions are met, removing the need for intermediaries.
How blockchain works
The process of a blockchain transaction takes place in several stages:
Transaction creation: A user initiates an operation, such as the transfer of a digital asset.
Network verification: The transaction is validated by nodes through a consensus mechanism.
Recording in a block: Once approved, the transaction is grouped with others in a new block.
Linking to the chain: The block is linked to previous blocks, ensuring the integrity of the information.
Network update: All nodes store an updated copy of the blockchain.
Applications of blockchain technology
Blockchain technology may be used for the digital representation of certain rights or assets, the automation of processes through smart contracts, and the verifiable recording of transactions, depending on the specific use case and the applicable legal framework.
Importance of blockchain
Blockchain technology is a tool used in various digitalisation processes due to its technical characteristics of distributed recording and verifiability.
Its use and scope depend on the specific case and the applicable legal framework.
