- Blockchain, the underlying technology behind most cryptocurrencies, is a distributed ledger that ensures transparency, security, and immutability. Each block in the chain contains a list of transactions, and once a block is added to the blockchain, it is nearly impossible to alter.
- Smart contracts (like those used on Ethereum) are self-executing contracts with the terms of the agreement directly written into code. These are used in decentralized applications (DApps) for purposes such as decentralized finance (DeFi), gaming, and supply chain tracking.
