# What is Blockchain? ## Blockchain ***The blockchain can best be defined as a public database that is updated and shared across a network of computers. Data and status are kept in batches or "blocks" in sequential order.*** You must add transaction data to a block in order to interact with the blockchain successfully. "Chain" signifies that each block has an encrypted reference to its parent block. A block's data cannot be modified without also altering all subsequent blocks, which necessitates network-wide consensus. Every computer in the network must approve each new block and chain as a whole. These machines are known as "nodes," and they all share the same data. To make this distributed protocol a reality, the blockchain needs a consensus mechanism. ## **Why does Sindia use blockchain technology?** ***Sindia's blockchain allows digital assets to be owned through non-fungible tokens (NFTs)***. It also allows ***extremely secure and transparent transactions.*** Because of these qualities, you will be able to fully own your Sindia digital assets, and you will be able to freely exchange them, exactly like physical trading cards, but in an ideal information market. Sindia may also leverage blockchain to construct unique game elements like earning magic or winning gold tickets by using smart contracts. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
