A blockchain allows the data in a database to be spread out among several network nodes — computers or devices running software for the blockchain — at various locations. This not only creates redundancy but maintains the fidelity of the data. For example, if someone tries to alter a record at one instance of the database, the other nodes would prevent it from happening. This way, no single node within the network can alter information held within it.
Because of this distribution — and the encrypted proof that work was done — the information and history (like the transactions in cryptocurrency) are irreversible. Such a record could be a list of transactions (such as with a cryptocurrency), but it also is possible for a blockchain to hold a variety of other information like legal contracts, state identifications, or a company’s inventory.
Blockchain Transparency
Because of the decentralized nature of the Bitcoin blockchain, all transactions can be transparently viewed by either having a personal node or using Blockchain that allow anyone to see transactions occurring live. Each node has its own copy of the chain that gets updated as fresh blocks are confirmed and added. This means that if you wanted to, you could track a bitcoin wherever it goes.
For example, exchanges have been hacked in the past, resulting in the loss of large amounts of cryptocurrency. While the hackers may have been anonymous — except for their wallet address — the crypto they extracted are easily traceable because the wallet addresses are published on the blockchain.
Of course, the records stored in the Bitcoin blockchain (as well as most others) are encrypted. This means that only the person assigned an address can reveal their identity. As a result, blockchain users can remain anonymous while preserving transparency.
