The decentralized, egalitarian and highly secure design of the blockchains allows it to operate without control, government or other opaque intermediaries (they are autonomous). They work because, rather than despite, people don’t trust each other.
What are the benefits of this system over the banking system?
The response is trust. As previously mentioned, it is important for Rob to trust his bank to protect his money and to deal with it properly. To ensure that this occurs, massive regulatory systems are in place in check and ensure the actions of banks are fit for purpose. Governments then oversee supervisors and establish a kind of tiered control system that only seeks to prevent errors and wrongdoing.
In other words, it is primarily because banks cannot be trusted on their own that organizations like the Financial Services Authority exist. Yet, as we have seen too many times, banks still make mistakes yet misbehavior. If you have a single authority source, power is often exploited or misused. The relationship of trust between people and banks is complex and precarious: we don’t trust them, but we don’t believe there’s a lot of alternatives.

Centralized data is controllable and, therefore, the data is susceptible to manipulation and theft. On the other hand, there are no centralized vulnerabilities in a blockchain to hacking and corrupting the details. Due to the distributed blocks of similar information over the blockchain network, a single entity cannot be managed, it has no single point of failure and, thus, cannot be retroactively changed. Anything on a blockchain is a feature of the entire network.
On the other side, Blockchain systems don’t need you to trust them. All transactions (or blocks) in a blockchain are checked by network nodes before they are added to the ledger, ensuring that there’s no single point of failure and no single channel of approval. If a hacker wanted to manage the ledger effectively on a blockchain, they would have to hack millions of computers simultaneously, which is practically impossible.
A hacker would also be quite unable to access a blockchain network, as they would need to be able to shut down every single computer in a worldwide network of computers. Once the transaction is accepted and registered in the ledger, it can be completed. This is how Bitcoin-like cryptocurrencies function.
Another key factor is the encryption method itself. Blockchains like Bitcoin use intentionally daunting methods to validate them. In the case of Bitcoin, nodes actively carry out processors and time-intensive calculations are checked for blocks, often as puzzles or complex mathematical difficulties, which means that the verification is neither instantaneous nor available.
Nodes committing the resource to test blocks are compensated with the transaction fee and the allocation of newly minted Bitcoins. This both encourages people to become nodes while controlling the process of producing–or minting–currency units. This is called mining because of a considerable amount of effort (in this case by a computer) is involved in producing new material. It also ensures that transactions are reviewed more objectively than a government-controlled agency like the FSA in the most unbiased way possible.
