 This does mean there's currently a need to trust the more technical members of the Ethereum community who can read code. The open-source based community helps keep developers in check, but this need will diminish over time as smart contracts become easier to read and other ways to prove trustworthiness of code are developed.

 4. [The applications](/dapps/) – the products we use to manage and access the protocols.

 ## Build DeFi {#build-defi}
 
 DeFi is an open-source movement. The DeFi protocols and applications are all open for you to inspect, fork, and innovate on. Because of this layered stack (they all share the same base blockchain and assets), protocols can be mixed and matched to unlock unique combo opportunities.
