![]() The first widely publicized hack involved Bitcoin-the most prevalent application of blockchain. ![]() In fact, blockchain technology proved long ago that it is hackable. But despite the benefits of blockchain, even the best-designed blockchain systems are not immune to attack. As a de-centralization technology where users can remain anonymous, blockchain makes it hard for regulators to deal with and allows for potential security threats. As with all technology, blockchain has its own weak points. This makes it difficult to hack a single record because the hacker would need to change the block containing that record as well as those linked to it to avoid detection. Moreover, because blockchains are decentralized and distributed across peer-to-peer networks that aren’t contained in a central location, blockchains don’t have a single point of failure and cannot be changed from a single computer.īlockchain technology has the possibility to solve data breach problems by removing the trust involved in the storage and access of digital content. Thus, no single entity can take control of the data in the blockchain. Each block is then linked to a specific participant. Blockchain can only be updated by consensus between users in the system, and when new data is entered, it can never be erased, edited, adjusted, or changed.īecause blockchain uses cryptography to connect the contents of the newly added block with each block before it, any change to the contents of a previous block in the chain would invalidate the data in all blocks following it. Each transaction, or “block”, is time-stamped and linked to the previous one. Blockchain technology is seeing increasingly wide use internationally, but security issues are becoming a major problem.īlockchain is a public electronic ledger that can be openly shared among users and that creates an unchangeable record of their transactions.
