Understanding the term
Metadata is defined as the data that provides information about one or more aspects of the data, used to summarize basic information about data that can make the tracking of specific data easier. Metadata is stored and managed in a database called a metadata repository or a metadata registry. The data found in cryptocurrencies can be broken down into three general categories. The Bitcoin blockchain saves metadata besides recording transfers of currency.
Metadata are arbitrary pieces of data that do not affect the transfers of Bitcoin. This can be done using many different techniques for different purposes. For instance, there are certain protocols that embed metadata in the blockchain for certification and transfer of ownership of assets beyond cryptocurrencies. In Ethereum, all the blocks store data and metadata about Ethereum, which is secure from tampering yet accessible to authorized users of the node. All the metadata accompanies it across the chain.
Takeaway
The meaning of metadata is data that includes information about other data, such as information about the features of a specific transaction in a blockchain network.
