What is a Blockchain?

A blockchain is a decentralized digital record that stores information securely and permanently by creating blocks that are linked to each other chronologically. Each block contains information verified and validated by a network of nodes or participants, which makes it resistant to manipulation or alteration. It is mainly used for the creation of cryptocurrencies, but it also has applications in other areas, such as identity management, electronic voting and product traceability.

What is Nodos?

A node is any device that is connected to the blockchain network and helps maintain and validate information on the blockchain. Each node has a full copy of the blockchain and is connected to other nodes on the network, allowing for the transmission of information and verification of transactions. Nodes can be managed by individuals or by organizations, and can be geographically distributed around the world. Nodes can also have different functions, such as validating transactions and creating new blocks, helping to maintain the security and integrity of the blockchain network. In short, nodes are essential components of the blockchain network that allow for decentralization and verification of transactions.

What is a decentralized registry?

A decentralized registry is a database that is not located in a single centralized location or entity, but rather is distributed across multiple locations or nodes that are part of a decentralized network. This means that there is no central entity that has absolute control over the database, but the information is shared and validated by all the nodes in the network.

In the context of blockchain, a decentralized ledger refers to the blockchain that contains all transactions and data validated by all nodes in the network. Each node has a full copy of the decentralized ledger and is therefore capable of verifying any transaction or change in information. Registry decentralization increases security as there is no single point of failure and reduces the risk of data tampering.
