Blockchain
As we briefly touched upon earlier, the Blockchain framework has several properties that make it apt to solve some of the data ownership, security, and privacy challenges. In today's mostly non-quantum technology landscape, Blockchain also provides data security better than centralized data management systems. At the same time, Blockchain has limitations that might affect mainstream adoption if not addressed. The history and the technology architecture of Blockchain (the Bitcoin Blockchain) was discussed in Chapter 1, Introduction to Quantum Computing and Blockchain.
There are several properties of Blockchain that allow its application across multiple industries. However, keeping our focus upon the topic of the data economy, let us see how Blockchain and its capabilities joined the party at the perfect time.
