Blockchain technology has become growingly prevalent in recent years as the cryptocurrency markets have stepped toward centre stage. Its quick adoption is because the Blockchain is designed to offer matchless security to digital data.
In its short span, Blockchain, known as distributed ledger technology, along with the cryptocurrencies it powers, has witnessed its portion of successes and failures. And as its applications spread, blockchain security has become more crucial, and it is not simply for cryptocurrency investors.
Though blockchain technology is already making a significant impact in different industries, there are still some concerns related to its security. However, you can make Blockchain secure in the following three ways.
- Integration of Secure QR Codes
You can go for blockchain secure QR code integration and ensure that the documents are secure. Whether you want to protect your educational documents, financial files, transactions or anything else, secure QR codes can ensure complete security and immutability. Once you want to access data, you can only get access to the genuine data if you scan the document. Once you scan the document, the scanner will match the QR code’s hash value with the QR code’s Hash value on the blockchain network. Hence, the data will reveal if the hash values match up. Hence, you can achieve a tamper-proof experience.
- Create a Strong Infrastructure
When forming a private blockchain, you should decide on the most refined platform for deployment. Even though Blockchain has characteristic properties that offer security, people with ill intentions will try to manipulate the known susceptibilities in your infrastructure. Therefore, if possible, you should have an infrastructure having integrated security that can:
- Stop anyone, even the root users as well as administrators, from accessing any confidential or sensitive information
- Repudiate illicit attempts to alter data or applications inside the network.
- Prudently guard encryption keys with the use of the highest-grade security standards. So, nobody can misappropriate them.
Blockchains depend much on cryptography to accomplish their data security. In this context, the supposed cryptographic hashing functions are of much importance. Hashing is a procedure in which an algorithm (hash function) gets an input of data of any size as well as returns an output (hash) that includes a foreseeable and fixed size.
Remember that the output will always be present at the same length irrespective of the input size. But in case the input alters, the productivity will be completely different. However, if the input does not alter, the resulting hash will always be identical no matter how many times you operate the hash operation.
The output values, called hashes, are used as distinct identifiers for data blocks in blockchains. The hash of every block is produced in link to the previous block’s hash. Now, it is what exactly creates a chain of linked blocks. The hash of a box depends on the data inside that block. It simply means if anyone makes any changes to the data, it would demand an alteration to the block hash. Hence, the production of a hash of each block is based on both the data contained inside that block. Hence, there can be utmost security in the Blockchain.
The Bottom Line
Though Blockchain is one of the most secure data protection technologies today, you cannot take its security for granted. Since Blockchain technology evolves, so will its susceptibilities. It is only a matter of time before hackers will find a path to breach Blockchain networks.
