DeFi (Decentralized Finance) on the Bitcoin blockchain would look quite different from DeFi on other blockchains like Ethereum. This is because Bitcoin was not originally designed for smart contract functionality, which is essential for the development of DeFi applications. Instead, the Bitcoin blockchain was designed to facilitate peer-to-peer transactions. However, there are some emerging technologies that aim to bring DeFi to the Bitcoin blockchain. Here are some possible ways that DeFi could work on the Bitcoin blockchain:
- Sidechains: Sidechains are separate blockchains that are pegged to the Bitcoin blockchain. Developers can create smart contracts on these sidechains, allowing for DeFi applications to be built on top of them. For example, the Liquid Network is a sidechain that enables fast and confidential transactions between exchanges and other Bitcoin businesses. Other sidechains on the Bitcoin blockchain include Stacks, Rootstock, and Lightning network which are discussed below:
- Rootstock: Rootstock (RSK) is a sidechain that is compatible with Ethereum, allowing for smart contracts to be written in Solidity (the same programming language used for Ethereum smart contracts). This means that DeFi applications built for Ethereum could potentially be ported to the Bitcoin blockchain using Rootstock.
- Lightning Network: The Lightning Network is a layer-two scaling solution for Bitcoin that enables fast and cheap transactions. It is possible that DeFi applications could be built on top of the Lightning Network, although it would require significant development work.
- Bitcoin-integrated Wallets: DeFi for Bitcoin could involve the integration of Bitcoin wallets with DeFi protocols. This would allow Bitcoin holders to access DeFi applications directly from their wallets, without having to transfer their Bitcoin to a centralized exchange. Bitfinity Wallet will be a Bitcoin-integrated wallet.
- Wrapped Bitcoin: Wrapped Bitcoin (WBTC) is a token that represents Bitcoin on the Ethereum blockchain. It is used to bring liquidity from Bitcoin to Ethereum-based DeFi applications. Similarly, a tokenized version of Bitcoin could be created on the Bitcoin blockchain, which could then be used in DeFi applications.
- Liquidity Pools: Liquidity pools are a core component of many DeFi applications, allowing users to earn rewards by contributing liquidity to the pool. With Bitcoin-based liquidity pools, users could earn rewards by contributing Bitcoin to the pool, which could then be used to power DeFi applications. InfinitySwap is offering liquidity pools.
- EVM integration with Bitcoin: Ethereum Virtual Machine (EVM) will be integrated with Bitcoin by the Bitfinity Network to allow for the execution of smart contracts on the Bitcoin blockchain, enabling DeFi applications that are built on top of the Bitcoin blockchain.
- Decentralized exchanges: One of the core features of a Defi ecosystem is the presence of decentralized exchanges (DEXs) that allow users to exchange their assets without any intermediary. Bisq, a decentralized exchange currently operates on the Bitcoin blockchain. However, it has limited features compared to the DEXs on other blockchains.
- Lending protocols: Lending protocols are platforms that allow you to deposit your Bitcoin and other tokens as collateral to get loans. Also, you can lend your tokens to other users in return for an annual yield. The Bitcoin ecosystem currently has a limited number of lending protocols, with the most popular being Sovryn Protocol.
Overall, while DeFi on the Bitcoin blockchain may not yet be as robust or flexible as on other blockchains, there are still several ways in which it could be implemented.
InfinitySwap will be aiming for DeFi to gain significant traction on the Bitcoin blockchain via its liquidity pools, Bitcoin-enabled wallet, and Bitcoin integration leveraging EVM, unleashing the true potential of Bitcoin via smart contract functionality.
