Blockchain is about more than just cryptocurrencies π
β
Secure storage and transmission of data is a headache of our time. Thick stacks of papers are all too easy to destroy or tamper with, and services for working with large databases can fail at any time and permanently delete information.
β‘οΈ The pill that helps relieve that pain is blockchain technology. A couple of scientists described its first principles back in 1991. To check originality, they suggested encrypting documents cryptographically, turning them into a chain of blocks, and adding time stamps to each block.
β‘οΈ So why, after so many years, did everyone suddenly remember and start implementing blockchain? There are several reasons for this:
β Security and invulnerability. Due to decentralization (more details in the next post), it is impossible to fake or change data in the blockchain.
β No intermediaries. All transactions (data transfers) are peer-to-peer, i.e. from one user to another.
β Instancy and availability. Transfers online happen in seconds and can be sent anywhere in the world.
π Blockchain has made alternatives to traditional payment systems, online data storage and even the most transparent and fair elections possible. The technology is considered revolutionary for a reason.
