Metadata in Blockchain Transactions Explained

Metadata, which includes timestamps, transaction details, smart contract data, and more, enables various functions and storage capabilities in blockchain networks. Metadata in blockchain is used in sectors such as healthcare, digital identity, smart contracts, and nonfungible tokens (NFTs). However, challenges including scalability issues, data security concerns, and Oracle dependability must be addressed for broader implementation. Solutions may include layer-2 and sharding techniques, permissioned blockchains and encryption, and multiple data sources for Oracle.
