Decentralized finance (DeFi) has become an increasingly popular alternative to traditional finance, with its decentralized, open-source and transparent nature making it an attractive option for many. However, the DeFi ecosystem can be complex and challenging to navigate, with multiple layers and networks.

Layer 1 Networks

At the core of the DeFi ecosystem are Layer 1 networks. These are the underlying blockchain protocols that power DeFi applications, and there are several different Layer 1 networks available. The most popular Layer 1 network is Ethereum, which is known for its programmability and ability to create smart contracts. Other Layer 1 networks include Binance Smart Chain, Solana, and Polkadot.

Layer 2 Networks

Layer 2 networks build on top of Layer 1 networks and are designed to enhance the scalability and efficiency of DeFi applications. Layer 2 solutions can be used to increase transaction speeds, lower fees, and improve the overall user experience. One example of a Layer 2 solution is the Lightning Network, which is built on top of the Bitcoin blockchain and is used to facilitate fast and cheap transactions.


Sidechains are separate blockchains that are attached to Layer 1 networks and are used to improve the efficiency of DeFi applications. Sidechains can be used to move certain types of transactions off the main blockchain, reducing congestion and improving scalability. One popular sidechain is Polygon, which is used to enable faster and cheaper transactions on the Ethereum network.

Off-Chain Networks

Off-chain networks are designed to enable instant, low-cost transactions that do not need to be verified by the main blockchain. These networks work by creating private channels between users, allowing them to transact without the need for intermediaries. One example of an off-chain network is the Raiden Network, which is built on top of Ethereum and is used to facilitate instant micropayments.

The differences between these layered networks can be significant. Layer 1 networks are fundamental to the DeFi ecosystem, providing the underlying infrastructure for DeFi applications. Layer 2 networks are designed to improve the scalability and efficiency of DeFi applications, while sidechains and off-chain networks are used to reduce congestion and enable faster transactions.

In conclusion, understanding the different layered networks within DeFi is essential for anyone looking to participate in the DeFi ecosystem. While the DeFi ecosystem may be complex, it is important to remember that it is built on a foundation of transparency, decentralization, and open-source software, which has the potential to transform the world of finance.
