The basic idea behind blockchain technology is that it allows multiple parties to have a shared view of a transaction or piece of information without the need for a central authority. Each transaction is recorded in a "block" and added to a "chain" of previous transactions, creating an immutable record that can be verified by anyone with access to the network.
One of the key features of blockchain technology is its transparency. Since all transactions are recorded on a public ledger, anyone can view and verify them. This makes it difficult for fraud or manipulation to occur, as any changes to the ledger would require the consensus of the entire network.
Another important feature of blockchain technology is its security. Each transaction is encrypted and linked to the previous transaction in the chain, making it virtually impossible to alter or tamper with the data. Additionally, since the ledger is distributed across multiple computers, there is no single point of failure or vulnerability.
