But hashes are not enough to stop manipulation.
But hashes are not enough to stop manipulation. Computers are now extremely fast and can calculate hundreds of thousands of hashes per minute. You can tamper or recalculate any hashes in a blockchain to make it legitimate again. This is a technique that slows down the process of creating new blocks. For Bitcoin, it takes approximately 10 minutes to calculate the proof_of_work required and add a new block. Because you can't tamper the blocks, this makes it extremely difficult. If you mess with one block, you will have to recalculate proof_of_work for all the others. A blockchain's security comes from its innovative use hashing and proof_of_work methods. Blockchains can also be protected by being distributed.

The node may use this information to make sure that everything is working properly. Let's take a look at the process of creating a new block. Every member of the network gets the new block. Each node then verifies the block to make sure it isn't tampered with. If everything is correct, each node adds the block to its own blockchain. The network's nodes join together to form a consensus. They have agreed on which blocks are legal and which ones are not. The network's other nodes will reject any blocks that have been altered. You must manipulate all blocks of the blockchain to be able to tamper.

Only then, the rest of the universe will acknowledge your modified block. This is not easy! Blockchains are also in constant evolution. One of the most recent innovations is smart contracts. These contracts, which are basically scripts that can be used to automatically exchange currencies based upon certain conditions, are stored on the blockchain. Many people were intrigued by the invention of blockchain technology. The technology could be used for many purposes. It can be used to keep medical records, create a digital notary and collect taxes. Now you understand what a blockchain is and how it works.
