Decentralized Finance (DeFi) In A Nutshell For Business People

Decentralized finance (DeFi) refers to an ecosystem of financial products that do not rely on traditional financial intermediaries such as banks and exchanges. Central to the success of decentralized finance is smart contracts, which are deployed on Ethereum (contracts that two parties can deploy without an intermediary). DeFi also gave rise to dApps (decentralized apps), giving developers the ability to build applications on top of the Ethereum blockchain.

Understanding decentralized finance

Decentralized finance is as much a philosophy as it is a way of doing business. Indeed, DeFi advocates a transparent financial ecosystem that is open-source, available to everyone, and operates without a central authority.

Central to the success of decentralized finance is the use of smart contracts, which are deployed on Ethereum. Smart contracts avoid the need to involve traditional intermediaries, who often charge exorbitant fees to facilitate financial transactions. Decentralized finance provides these same services in a faster and cheaper way that is also more secure.

Smart contracts also give developers increased functionality. Instead of simply building programs that send or receive cryptocurrency, smart contracts can be used to build programs on the blockchain that execute when certain conditions are met. 

These programs are now commonly referred to as decentralized apps, or dApps. Collectively, dApps comprise a DeFi ecosystem.

The core components and criteria of dApps

To understand DeFi it is important to first understand dApps. 

Structurally, a dApp consists of:

  • A front-end interface – such as an app or website.
  • A smart contract – or a program that facilitates online transactions autonomously according to programmed rules. Smart contract code can be audited to verify that it is bug-free and non-malicious.
  • The Ethereum blockchain – which ensures that the smart contract cannot be hacked or otherwise tampered with. It’s also important to note that a fee (calculated in ETH) is charged to the user every time a smart contract is utilized.

The dApp architecture is also characterized by four criteria:

  1. It must be entirely open-source. No entity must own the majority of tokens and protocol changes must be decided via network user consensus.
  2. Data must be stored on a decentralized blockchain.
  3. Each dApp must generate tokens acting as proof of value.
  4. Tokens must be distributed as rewards on the network.

Potential applications of decentralized finance

In theory, the applications of decentralized finance are limitless.

Having said that, here are a few of the most salient:

Monetary banking services

Monetary banking is an obvious use, but one that is maturing through the creation of stablecoins. These coins are a type of crypto-asset, usually pegged to a real-world asset such as fiat money or exchange-traded commodities.

Decentralized stablecoins help mitigate the volatility seen in cryptocurrencies, allowing them to be used as a form of cash without the need for a central authority. Stablecoins might also be beneficial in processes that require many intermediaries, such as mortgage or insurance applications.

Borrowing and lending

DeFi has several advantages over the traditional credit system of borrowing and lending. These include the ability to collateralize digital assets and provide instantaneous settlement. DeFi also negates the need for credit checks and through standardization, can make the process more efficient. 

For the lender, blockchain reduces the risk of default. Lenders can also offer cheap and fast services to a broader audience of borrowers. 

Decentralized marketplaces

Some argue that decentralized marketplaces offer the most room for DeFi innovation

This is most applicable to decentralized exchanges (DEXes), which allow users to trade digital assets without requiring the exchange to hold their funds.

Platforms that issue security tokens, for example, may give users the tools and resources necessary to launch tokenized securities on the blockchain. The same might also be possible for derivative, futures, and synthetic asset markets.

Key takeaways:

  • Decentralized finance is a suite of financial products and services that operate without a traditional intermediary such as a bank or exchange.
  • Decentralized finance is based on decentralized apps, or dApps. Each dApp has a user interface and smart contract based on the Ethereum blockchain.
  • Decentralized finance has the potential to revolutionize monetary banking services, borrowing and lending, and traditional, centralized marketplaces.

Connected Business Concepts

A free-to-play is a model that became particularly popular in gaming. Free-to-play is also commonly referred to as free-to-start. For instance, companies like Epic Games have launched popular games like Fortnite’s Battle Royale, which had ingrained a free-to-play model. This is a model that become extremely popular in the digital age of gaming.
According to Joel Monegro, a former analyst at USV (a venture capital firm) the blockchain implies value creation in its protocols. Where the web has allowed the value to be captured at the applications layer (take Facebook, Twitter, Google, and many others). In a Blockchain Economy, this value might be captured by the protocols at the base of the blockchain (for instance Bitcoin and Ethereum). However, according to blockchain investor Paivinen due to ease of forking, incentives to compete and improved interoperability and interchangeability also in a blockchain-based economy, protocols might get thinner. Although the marginal value of scale might be lower compared to a web-based economy, where massive scale created an economic advantage. The success of the Blockchain will depend on its commercial viability!
A Proof of Stake (PoS) is a form of consensus algorithm used to achieve agreement across a distributed network. As such it is, together with Proof of Work, among the key consensus algorithms for Blockchain protocols (like the Ethereum’s Casper protocol). Proof of Stake has the advantage of security, reduced risk of centralization, and energy efficiency.
A Proof of Work is a form of consensus algorithm used to achieve agreement across a distributed network. In a Proof of Work, miners compete to complete transactions on the network, by commuting hard mathematical problems (i.e. hashes functions) and as a result they get rewarded in coins.
A Blockchain Business Model according to the FourWeekMBA framework is made of four main components: Value Model (Core Philosophy, Core Values and Value Propositions for the key stakeholders), Blockchain Model (Protocol Rules, Network Shape and Applications Layer/Ecosystem), Distribution Model (the key channels amplifying the protocol and its communities), and the Economic Model (the dynamics/incentives through which protocol players make money). Those elements coming together can serve as the basis to build and analyze a solid Blockchain Business Model.
Ethereum was launched in 2015 with its cryptocurrency, Ether, as an open-source, blockchain-based, decentralized platform software. Smart contracts are enabled, and Distributed Applications (dApps) get built without downtime or third-party disturbance. It also helps developers build and publish applications as it is also a programming language running on a blockchain.
The Graph is an ERC20 Utility Token (built on top of Ethereum) to enable consumers to freely query the blockchain through a fully decentralized database kept by indexers, incentivized by the payment of tokens (called GRT). The network is also ministered by curators and delegators that help maintain a high-quality index.
BAT or Basic Attention Token is a utility token aiming to provide privacy-based web tools for advertisers and users to monetize attention on the web in a decentralized way via Blockchain-based technologies. Therefore, the BAT ecosystem moves around a browser (Brave), a privacy-based search engine (Brave Search), and a utility token (BAT). Users can opt-in to advertising, thus making money based on their attention to ads as they browse the web.
In 2012, co-founders Christian Larsen and Jed McCaleb created Ripple, a technology acting as both a pre-mined cryptocurrency called XRP and a digital payment platform enabling monetary transactions. Where Ripple is the tech company, XRP is the decentralized ledger.
In 2014, Jed McCaleb – which also played a key role in the development of Ripple – created a cryptocurrency to provide fast, reliable, and affordable money transactions. The same cryptocurrency has considerably grown seven years later. It is now one of the most stellar cryptocurrencies to provide a real-time platform that links banks, payment systems, and people. Meet, Stellar!
In early 2019, a joint project between TRON and BitTorrent Foundation called BitTorrent Token came to fruition. BitTorrent Token launched to tokenize in-demand file-sharing protocol and enhance content delivery and bandwidth accessibility with blockchain technology.
Chainlink is considered the most established decentralized oracle network. As an ecosystem housing several decentralized oracle networks running simultaneously. As a decentralized oracle service built on Ethereum, Chainlink has the power to support the development of blockchain solutions for both traditional businesses and enterprises.
Uniswap is a renowned decentralized crypto exchange created in 2018 and based on the Ethereum blockchain, to provide liquidity to the system. As a cryptocurrency exchange technology that operates on a decentralized basis. The Uniswap protocol inherited its namesake from the business that created it — Uniswap. Through smart contracts, the Uniswap protocol automates transactions between cryptocurrency tokens on the Ethereum blockchain.
In essence, Polkadot is a cryptocurrency project created as an effort to transform and power a decentralized internet, Web 3.0, in the future. Polkadot is a decentralized platform, which makes it interoperable with other blockchains.
Designed and created as an alternative to Ethereum, Cardano claims to be the first decentralized blockchain protocol to use a scientific approach and undergo a peer evaluation.
Solana is a blockchain network with a focus on high performance and rapid transactions. To boost speed, it employs a one-of-a-kind approach to transaction sequencing. Users can use SOL, the network’s native cryptocurrency, to cover transaction costs and engage with smart contracts.
