Metadata in the context of blockchain refers to information that describes and gives context to other data, such as transaction time, involved parties, amounts, and the transaction’s purpose.
While the actual data (e.g., transactions) represents the core value, metadata plays a crucial role in ensuring that this data is understood, traceable, and verifiable.
It’s often used in auditing, compliance, and improving the transparency and security of blockchain systems. In blockchain, metadata also helps in categorizing and organizing data for better searchability and access.
Blockchain is a decentralized, distributed digital ledger technology that makes it possible to securely and openly record and share data among many parties.
A decentralized network's distributed ledger is a database that is updated and synchronized across numerous nodes or computers. Without the requirement for a centralized authority, it enables participants to securely and transparently record, preserve, and amend transactions or data. Blockchain systems are based on distributed ledger technology, which offers an unchangeable and impenetrable record of all network activity.
