The component of blockchain networks that holds and broadcasts information to other components.

A node is essentially the part of blockchain networks that collect and broadcast valuable information to other components, especially other nodes. These nodes are really computers owned by network validators to share data about transactions so that it can be verified and recorded in the blocks. Nodes, therefore, are components for communication, and allow users to interact with a network.

There are different types of nodes. The most common one is the full node which serves as a miniature copy of the ledger containing transaction records.

A variety of uninterchangeable crypto assets known for being unique and used to represent digital art.

A non-fungible token (NFT) is a crypto asset that represents an asset in the real world, usually in the form of art. NFTs are always unique, meaning that there are no two identical tokens, even though they might share similar qualities such as color and shape. NFTs are also not interchangeable, a quality which solidifies their position as unique tokens which only have a representative purpose.

Although there are different applications of NFTs in the world of cryptos, the most traditional application is their use to stand in for digital art. However, NFTs can be created and sold, and some of them have been sold for a lot of money.

A mechanism that allows multiple individuals to have access to the same wallet, but restricts the execution of transactions until all signatories approve.

Multisignature (multisig for short) is a kind of contract mechanism used in corporate finance (generally banking) to secure accounts. In the traditional banking case, multisig allows two or more persons to have access to the same account. However, whenever a transaction is made by one of these persons, the others have to endorse it or it will not be executed.

Multisig has been adapted to crypto space, allowing multiple traders to use the same wallet address. However, once again, all involved parties must approve of every transaction from the address before said transactions will be carried out.
