A blockchain registry is a system that records and verifies transactions or assets on a blockchain. It functions like a digital ledger, ensuring that all entries are secure, transparent, and immutable.In this registry, each transaction is organized into blocks that are linked together in chronological order. Once a block is added to the chain, it cannot be changed or deleted, making the records highly reliable. This feature helps prevent fraud and enhances trust among users.Blockchain registries can be used for various purposes, such as tracking ownership of assets, managing identities, or recording agreements. They eliminate the need for centralized authorities, allowing participants to engage directly with each other. The decentralized nature of blockchain ensures that no single entity has control over the entire registry, further enhancing security and reducing the risk of manipulation. This technology has applications across industries, including finance, real estate, and supply chain management, making it a versatile tool for establishing and maintaining records.
