Welcome to the Blocks educational newsletter on how Crypto works.
Cryptocurrency is a digital asset that uses cryptography for security and is decentralized, meaning it is not controlled by any government or financial institution. The mechanisms behind cryptocurrency are complex and involve the use of various technologies and algorithms.
One of the key technologies behind cryptocurrency is blockchain. A blockchain is a decentralized, distributed ledger that records transactions across a network of computers. Each block in the chain contains a record of multiple transactions, and once a block is added to the chain, it cannot be altered. This ensures the integrity and security of the transaction record.
Cryptocurrency relies on the use of decentralized networks, meaning there is no central authority that controls the network. Instead, participants in the network reach consensus about the state of the ledger through a process known as mining. Miners use powerful computers to solve complex mathematical problems, and the first miner to solve the problem is rewarded with a fixed amount of cryptocurrency. This process helps to ensure the security and integrity of the network.
There are different consensus algorithms that are used by different cryptocurrencies. For example, Bitcoin uses a proof-of-work (PoW) algorithm, while Ethereum uses a proof-of-stake (PoS) algorithm. These algorithms determine how miners reach consensus and how new blocks are added to the chain.
In conclusion, cryptocurrency relies on complex mechanisms that involve the use of technologies such as blockchain and consensus algorithms. These mechanisms help to ensure the security and integrity of the network and enable the decentralized nature of cryptocurrency.
