A survey on blockchain technology and its security. Before looking for blockchain agencies to create a blockchain app, it is vital to have a clear understanding of this technology. Blockchain is considered to be the safest way to store information, which excludes data breaches and fraudulent activities, protects property rights, and the like. In simple words, this technology is an endless ledger of financial or other operations that can be used for monetary transactions and actually anything that has formal value. Safety is provided by these three factors:
- distribution register
- cryptographic encryption
- consensus algorithm
They build the most secure base system, which is almost impossible to tamper with. Blockchain has no weak points, and nobody can make changes to the transaction records. All information is stored on millions of computers located in different parts of the world. A transaction that is recorded on one computer or node is visible to every computer on the digital network. Everyone can see the same data. These are nodes that verify all the transactions created on the blockchain. New blocks that contain new information are always added to the end of the chain. Each add-on comes with a unique digital signature or hash. It is a series of numbers and letters, in other words, a secret mathematical code. If you change something in the block after it has been added, then these signatures will also change.
More and more companies are using blockchain across all business fields and industries, from healthcare to banking and accounting. There are enough top blockchain companies to develop a custom app for your idea.
