The term “blockchain” is a distributed ledger technology that is connected and linked in between nodes of a computer network that operates with trust and confidence in mind. Not just that, blockchain also acts as a database that stores information digitally. Cryptocurrency uses blockchain technology to ensure decentralization and also high-tier security to secure transaction records and assets that have sky-high value.
In the following, there will be the information about Blockchain Security Strategy.
1. Cryptography
Firstly, the blockchain utilize cryptography extensively to ensure the security of the records. Meanwhile, the participants on a network are storing their private keys. These have been assigned to them as a result of the transactions that they have completed. Moreover, these keys serve as digital signatures for individuals. In the event that any record is altered, this digital signature will no longer be valid, and the peer network will be notified that something is amiss.
2. Decentralization
Decentralization, the most important characteristics of blockchain that contributes to its high level of security. As well as, it distribute over peer-to-peer networks. These are updated regularly basis, so they are always up to date. There is no single point of failure or access because there is no connection to a centralized location. As a result, altering the blockchain will require a large amount of processing power or at the very least control over 51 percent of it. Not to mention, even the most skillful attackers and hackers would find this difficult. As a result, blockchains are extremely secure against tampering and fraud.
3. Pain Point of Blockchain
The system might seem impenetrable, but one of the most famous methods of hacks is still able to probe through security, which is social engineering. By tricking the owner of these blockchain user accounts using phishing or pharming, the malicious actors could still obtain and possess these accounts.
