Decentralized finance, or DeFi, uses emerging technology to remove third parties and centralized institutions from financial transactions. The components of DeFi are stablecoins, software, and hardware that enables the development of applications. The infrastructure for DeFi and its regulation are constantly evolving.
Decentralized finance uses the blockchain technology that cryptocurrencies use. A blockchain is a distributed and secured database or ledger. Applications called dApps are used to handle transactions and run the blockchain.
In the blockchain, transactions are recorded in blocks and then verified by other users. If these verifiers agree on a transaction, the block is closed and encrypted; another block is created that has information about the previous block within it.
The blocks are “chained” together through the information in each proceeding block, giving it the name blockchain. Information in previous blocks cannot be changed without affecting the following blocks, so there is no way to alter a blockchain. This concept, along with other security protocols, provides the secure nature of a blockchain.
