Blockchain is a decentralized and distributed digital ledger for transactions characterized by transparency, security, and difficulty of manipulation. Imagine a huge shared ledger among many computers around the world, where every transaction or new information is recorded in the form of a "Block" linked to the previous block in a sequential and encrypted manner (Chain).

Here is a simplified explanation of how blockchain works:

Transaction recording: When a transaction occurs (such as transferring digital currency, registering ownership, or tracking a product), this transaction is grouped with other transactions into a new "Block."

Block validity verification: This new block is sent to a network of computers (called "Nodes") spread around the world. These nodes verify the validity of the transactions within the block according to predefined rules (called "Consensus Mechanism").

Adding the block to the chain: Once the block is validated by the majority of nodes in the network, it is permanently added to the end of the current chain of blocks.
