Blockchain technology is a decentralized, distributed and secure database system that underpins cryptocurrencies. Blockchain, as the name suggests, consists of blocks that are chained together. Each block contains cryptocurrency transactions that took place within a certain time period. These transactions are verified and confirmed by all computers participating in the blockchain network. Thus, the record of transactions cannot be changed or deleted.
Blockchain technology can be used in many areas such as smart contracts, digital identities, supply chains, voting systems, as well as cryptocurrencies. Blockchain provides advantages such as security, transparency, traceability and efficiency. Blockchain networks are generally divided into two types, public or private. Open blockchains are blockchains that anyone can access and participate in. Private blockchains, on the other hand, are blockchains that only certain individuals or institutions can access and participate in.
Blockchain technology is one of the most important innovations that makes the use of cryptocurrencies possible. Thanks to the blockchain, cryptocurrencies can be transferred quickly, cheaply and securely without intermediaries. Any transaction performed on the blockchain network is called a transaction. Transactions are verified and confirmed by miners on the network before being added to blocks. Miners receive a cryptocurrency reward for this transaction.
