What is decentralized finance? An expert on bitcoins and blockchains explains the risks and rewards of DeFi

The Compound protocol makes this possible by creating liquidity for cryptocurrencies through interest rates set using computer algorithms. Certain decentralized applications require that real-world data be connected to the blockchain. For example, prediction markets treat real-world events, such as elections, as financial products and require the real-world data to be stored on-chain for funds to be released to those who predicted the results. Most smart contracts offer Turing Complete programming languages that allow multiple parties to interact with each other without a centralized intermediary. Blockchain’s ability to capitalize on smart contracts makes them ideal platforms to choose when building financial applications. Decentralized finances provide total transparency and high levels of security for financial transactions since every interaction will be recorded publicly on the blockchain ledger.

With DeFi, the markets are always open and there are no centralized authorities who can block payments or deny you access to anything. Services that were previously slow and at risk of human error are automatic and safer now that they’re handled by code that anyone can inspect and scrutinize. Though DeFi is usually a main player in the cryptocurrency conversation, it goes beyond creating an alternative digital currency or value.


The code for these financial applications is open for anyone to see and inspect. This is important because anyone is able to verify how the applications and protocols work, and track exactly where their money is. Augur is a decentralized prediction market platform that utilizes the collective prediction of the masses.

The newness of DeFi technology means that negative outcomes can unexpectedly occur. New companies that use DeFi technology may not succeed (failure among start-ups is exceedingly common), what is open finance in crypto and errors by programmers can create profitable opportunities for hackers. Investing in or storing money with a DeFi project that fails can result in the total loss of your funds.

By leveraging blockchain technology, Web3 allows for the creation of smart contracts, which are self-executing agreements that automatically verify and enforce the terms of a transaction. These smart contracts ensure that all parties involved in a transaction are held accountable, eliminating the need for trust. When it comes to programming languages, there are a few popular options to consider. Solidity, for example, is the language of choice for Ethereum smart contracts.

The biggest risk in the DeFi space, again, is the absence of regulations to protect your money. Because DeFi is an emerging industry, you run the risk of investing in a project that could fail. Plus, the cryptocurrency markets are highly volatile and complex, making it difficult to gauge both the market and industry.

Deposits with traditional centralized financial institutions are insured by the Federal Deposit Insurance Corporation (FDIC), while DeFi platforms generally don’t provide any means by which to recover lost money. If a traditional financial transaction goes awry, a consumer can file a complaint with the Consumer Financial Protection Bureau (CFPB), but no such recourse exists if you become a victim of a fraudulent DeFi transaction. At the end of August 2020, daily trading volume on Uniswap hit $426 million, surpassing the volume of centralized exchange Coinbase, on which traders exchanged $348 million worth of cryptocurrencies. 1inch aggregates all of the decentralized exchanges on one website.

Why smart contracts?

In these scams, developers create apparently legitimate cryptocurrency projects before stealing investor money and disappearing. Chainalysis warned that many attacks on DeFi exchanges over the past year can be https://www.xcritical.com/ traced back to errors in the smart contract code governing those protocols, which hackers exploit to steal funds. DeFi’s core premise is that there is no centralized authority to dictate or control operations.

  • With an Ethereum-based blockchain, smart contracts help the DeFi model work.
  • For example, if you had a centralized hurricane insurance policy and a hurricane caused property damage, you would have to go through a lengthy claims process before receiving the funds needed to repair your home.
  • Founded in 2018 by Hayden Adams, UniSwap is the largest automated token exchange by trading volume deployed on the Ethereum blockchain.
  • Stablecoins became useful during risky moments in the crypto space, providing a haven for investors and traders.
  • Truffle provides a suite of tools for developing, testing, and deploying smart contracts.
