Blockchain is a distributed ledger system in which a series of linked blocks are securely linked together using cryptographic methods. Each block contains the data of the previous block, and thanks to these connections, a chain of trust is created between blocks.
Blockchain is used to store and transfer data in a decentralized and reliable way. It is a technology that forms the basic infrastructure of cryptocurrencies (for example, Bitcoin and Ethereum). It can also be used as a platform to support automated transactions such as smart contracts.
DeFi is an acronym for “decentralized finance.” It refers to financial services created using blockchain technology and cryptocurrencies outside of traditional financial systems. DeFi uses technologies such as smart contracts to perform lending, exchange, liquidity and other financial transactions.
