What is DeFi? Everything you need to know about the future of decentralized finance
The Future of Money. From blockchain and bitcoin to NFTs and the metaverse, how fintech innovation is changing the future of money. Read More. Decentralized finance, or 'DeFi', is an emerging digital financial infrastructure that theoretically eliminates the need for a central bank or government agency to approve financial transactions.
Regarded by many as an umbrella term for a new wave of financial services innovation, DeFi is deeply connected with blockchain -- the decentralized, immutable, public ledger on which Bitcoin is based -- that enables all computers or nodes on a network to hold a copy of the history of transactions. The idea is that no single entity has control over, or can alter, that ledger of transactions.
Most of the financial services that could be defined as DeFi can be found on the Ethereum network , the second-largest cryptocurrency marketplace, which also acts as a platform that allows other blockchain apps to be built on it Ethereum's cryptocurrency, Ether, is used to pay transaction costs. By utilizing decentralized apps, or dApps, two or more parties can exchange, lend, borrow, and trade directly using blockchain technology and smart contracts without middlemen's involvement and costs.
It's a fair, free and open digital marketplace -- at least in theory. In practice, at least for now, that's not always the reality. To learn more about this new, digital financial marketplace, read on. While Bitcoin is a decentralized digital currency that operates on its own blockchain and is used mostly as a store of value, DeFi is a concept that describes financial services that are built on public blockchains, such as Bitcoin and Ethereum, that for example, enable users to earn interest or borrow against their cryptocurrency holdings.
DeFi is comprised of a variety of applications around financial services such as trading, borrowing, lending and derivatives. DeFi uses cryptocurrencies and smart contracts to provide financial services to eliminate the need for intermediaries such as guarantors. Such services include lending where users can lend out their cryptocurrency and earn interest in minutes rather than once a month , receiving a loan instantly, making peer-to-peer trades without a broker, saving cryptocurrency and earning a better interest rate than from a bank, and buying derivatives such as stock options and futures contracts.
To facilitate peer-to-peer business transactions, users utilize dApps, most of which can be found on the Ethereum network. DeFi is open source, meaning that protocols and apps are theoretically open for users to inspect and to innovate upon. As a result, users can mix and match protocols to unlock unique combinations of opportunities by developing their own dApps. It's computer code that acts as a digital agreement between two parties.
A smart contract runs on a blockchain and is stored on a public database, and can't be altered. Because the blockchain processes smart contracts, they can be sent automatically without a third party. The peer-to-peer transaction is closed only when the conditions in the agreement are met.
The obvious benefit of smart contracts is that they can be created for you to borrow and lend your cryptocurrency without the use of an intermediary, which sidesteps a lot of the risks involved in traditional lending. If, for example, a borrower can't meet their obligations in a loan, their lender can simply take their funds back, making the need for collateral unnecessary.
What's more, DeFi saving accounts could function in the same way as savings accounts at banks but might offer higher interest rates or could pay out either daily, weekly or monthly, depending on the platform.
No one person created the concept of decentralized finance. Bitcoin is said to have been created by Satoshi Nakamoto, a pseudonym for a person, or people, behind the world's first cryptocurrency and financial blockchain. The true identity, or identities behind Satoshi Nakamoto, remain unknown. Ethereum, the platform inspired by Bitcoin, and the one on which a majority of DeFi services run, was developed by programmer-turned-entrepreneur Vitalik Buterin.
In , at the age of 19, the Russian-Canadian wrote a white paper outlining an alternative platform to Bitcoin that would enable programmers to develop their own apps using a built-in programming language.
Thus, Ethereum was born, and over the past nine years, it has grown exponentially. As mentioned above, DeFi uses cryptocurrencies and smart contracts to provide financial services without the involvement of banks. With the addition of more dApps, the possibilities of what you can do with DeFi continue to grow. There's more than one way that people are attempting to capitalize on the growth of DeFi. One strategy is generating passive income using Ethereum-based lending apps.
Essentially users loan out their money and generate interest from the loans. Another strategy being used is yield farming , a riskier practice by more advanced traders, in which users scan through a myriad of DeFi tokens in the hopes of finding opportunities for larger returns, but it is complicated and can lack transparency.
Like all other new decentralized blockchain networks trading in cryptocurrencies, DeFi is very risky, especially as you're using a new technology that aims to disrupt an established institution such as a centralized bank. It's even riskier for novices lured by the potential gains of yield farming and passive income. Ethereum has security and scam prevention guidelines as there are also broader potential risks.
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 traced back to errors in the smart contract code governing those protocols, which hackers exploit to steal funds.
Code audits are a process through which a third-party firm analyzes the code of the smart contract behind a new token or other DeFi project and publicly confirms that the contract's governance rules are iron clad and contain no mechanisms that would allow for the developers to make off with investors' funds," Chainalysis said.
This dog-meme-based cryptocurrency is just one of the many cryptocurrencies around but has received attention thanks to Elon Musk and his appearance on Saturday Night Live.
As of mid-January , it is trading at around 15 cents a coin. And for a decentralized cryptocurrency that's based on a dog and started as a joke, some will argue that the price of 15 cents a dogecoin is about right. Then again, Bitcoin started at a fraction of a penny.
Despite Dogecoin's publicity, it's currently ranked 12th on a list of cryptocurrencies priced by market cap. These are known as "consensus mechanisms" and are central when confirming transactions on a blockchain. This is what cryptocurrency miners do when validating transactions. Miners in a blockchain network compete to find a cryptographic hash used in specifying a transaction.
Although the hash is difficult to find, it's easy to verify. Once verified, that transaction is added to the blockchain and is a fait accompli. The work that goes into verifying that hidden hash is called the "proof of work. In the case of Bitcoin, it's 6. This is known as mining Bitcoin. In this case, the staking of an asset on the next block in a blockchain replaces the mining of blocks as it is done under proof of work.
One major downside of proof of work is energy. To find that rare cryptographic hash requires a lot of computing power. Dozens, even hundreds, of computers coalesce to form one high-speed brain to solve complex mathematical equations to be the first to do the proof of work and earn a block. That proof of work consumes a lot of energy and is the reason why environmental groups are upset over blockchain and cryptocurrency mining. However, in proof of stake, validators stake some amount of their cryptocurrency to prove that the block is valid.
Once they stake their crypto assets, they are randomly selected to propose a block to validate. That block then needs to be authenticated by a majority of other validators -- those who validate profit by both proposing a block and authenticating others' proposed blocks. What is Web3?

Explanation of DeFi staking and the importance of Ethereum 2.0
Jeremy Eng-Tuck Cheah does not work for, consult, own shares in or receive funding from any company or organisation that would benefit from this article, and has disclosed no relevant affiliations beyond their academic appointment. One area in cryptocurrencies attracting huge attention is DeFi or decentralised finance. You can listen to more articles from The Conversation, narrated by Noa, here. This has driven a massive rise in the value market capitalisation of all the tradeable tokens that are used for DeFi smart contracts. Numerous tokens have risen in value by three or four times in a year — and some considerably more. For example, Synthetix Network Token has increased more than fold, and Aave almost fold. DeFi, most of it built on the ethereum blockchain network , is the next step in the revolution in disruptive financial technology that began 11 years ago with bitcoin. One area in which in which these decentralised applications dApps have taken off is cryptocurrency trading on decentralised exchanges dexs such as Uniswap. These are entirely peer-to-peer, without any company or other institution providing the platform. For example, you could buy a stablecoin such as DAI and then lend it on Compound to earn interest, all using your smartphone.
How DeFi is revolutionizing the financial industry
New platforms are allowing users to lend and borrow cryptocurrencies for profit — and threatening to make traditional financial intermediaries obsolete. Of all of the disruptive possible uses of blockchain, decentralized finance or DeFi might be the one most likely to bring this technology to a wide audience — and challenge the established finance industry in the process. By using self-executing contracts on newly formed marketplaces, DeFi allows users to stand in place of large institutions to loan and borrow money to each other, and to earn interest and fees by doing so. There is significant risk inherent these crypto markets, but DeFi offers a less volatile and more accessible point of entry than other markets — and may just have enough appeal to bring blockchain into the mainstream.

Bitcoin captured headlines as it rocketed to new highs in early Cryptocurrencies like Bitcoin are becoming mainstream. As they do, the technology that powers them is becoming more influential in our everyday lives. More and more businesses are using the blockchain-based technology behind Bitcoin to store data and make more efficient decisions.
A vision of finance: the rise of DeFi
Cryptocurrency hacks are common in DeFi. Decentralized finance DeFi seems a lot more complicated than it actually is. This is done through smart contracts, which are programs that live on the blockchain. Just like how Bitcoin is immutable and trustless, so are smart contracts. This allows for functions like peer-to-peer lending markets, streaming services and decentralized exchanges to be built into smart contract applications.

Decentralized finance DeFi offers financial instruments without relying on intermediaries such as brokerages , exchanges , or banks. Instead, it uses smart contracts on a blockchain. DeFi platforms allow people to lend or borrow funds from others, speculate on price movements on assets using derivatives, trade cryptocurrencies , insure against risks, and earn interest in savings-like accounts. The Ethereum blockchain popularised smart contracts, which are the basis of DeFi, in
