The benefit of Bitcoin, and other virtual digital cryptocurrencies, lies in their anonymity, and with blockchain-based technologies, they are typically thought to be incredibly secure as well. However, as some cryptocurrencies have discovered, they are not completely infallible – and this is doing some damage to the blockchain’s reputation. What makes the blockchain so secure? “Normal” transactions, using traditional currency, require a verification process between two parties, typically institutions such as banks or the Reserve Bank. Blockchain based transactions are no different, however the verification process is decentralised and spread across multiple verification points, or nodes. No single party controls any or all aspects of the transaction and verification takes place based on consensus. No single party controls any or all aspects of the transaction and verification takes place based on consensus. Due to the sheer number of nodes that need to verify and approve a transaction, it is incredibly difficult to hack, breach or otherwise intercept a transaction on the blockchain. This has resulted in financial institutions across the globe exploring the blockchain’s potential in other applications.
