Secure
The security of live blockchains is underpinned by sophisticated cryptographic techniques that safeguard data from unauthorized access and manipulation. These techniques play a pivotal role in ensuring the integrity and confidentiality of transactions recorded on the blockchain.
One of the fundamental cryptographic techniques used in live blockchains is public-key cryptography. This technique involves the use of two mathematically linked keys: a public key and a private key. The public key is shared publicly, while the private key is kept secret by the owner. When a user wants to send a transaction, they encrypt it using the recipient’s public key. Only the recipient, who possesses the corresponding private key, can decrypt and access the transaction.
In addition to public-key cryptography, live blockchains also utilize hashing functions to ensure the integrity of data. A hash function is a mathematical algorithm that converts a data block of any size into a fixed-size hash value. Any alteration to the data will result in a different hash value, making it computationally infeasible to tamper with data without detection.
The combination of public-key cryptography and hashing functions creates a robust security framework for live blockchains. It ensures that only authorized parties can access and modify data, and that any unauthorized attempts to alter the blockchain will be detected and prevented.
