Blockchain is a distributed recording technology that allows the creation of a decentralised and secure database, where transactions are recorded in cryptographically linked blocks, forming a chain of blocks.

Each block contains a record of verified transactions, and once a block has been created, it cannot be modified without affecting subsequent blocks in the chain. This means that blockchain technology provides a secure and reliable way of storing and sharing information without the need for a centralised intermediary.

Blockchain technology is used in a wide variety of applications, such as supply chain management, electronic voting, property registration, identity management, financial transactions and cryptocurrency creation.

In the context of artificial intelligence and machine learning, blockchain technology can be used to ensure the privacy and security of data used to train machine learning models, and to improve the transparency and traceability of artificial intelligence algorithms. In addition, blockchain can be used to create decentralised reputation systems, which can be useful for evaluating the quality of machine learning models and selecting suitable models for specific situations.
