Decentralized Finance Explained"},"content":{"rendered":"

Humble Beginnings<\/strong><\/h2>\n

There\u2019s growing excitement around Decentralized Finance, better known as DeFi, and for good reason: DeFi is bringing sweeping changes to finance, investing, and the way money moves.<\/p>\n

But where did DeFi come from, and what do its origins say about where it\u2019s about to take us?<\/p>\n

DeFi seems so complex to newcomers that it can feel hard to understand. But there\u2019s a way to get your head around it, and that starts with travelling back in time.<\/p>\n

Let\u2019s take a step back\u2026before Bitcoin, PayPal, credit cards, and drive-through ATMs to get some perspective. Then you\u2019ll see why DeFi is being called Finance 3.0 \u2014 and how Finance 1.0 and 2.0 became endangered species.<\/p>\n

Finance 1.0: Starting with Central Banks<\/strong><\/h2>\n

The last few centuries \u2014 and especially the last few decades \u2014 have seen many innovations in financial products and services. But despite consistent progress, there weren\u2019t a lot of big breakthroughs in the way money is managed and organized \u2014 for everyday people, businesses, or institutions.<\/p>\n

Today, the economies of most of the world\u2019s nations are tied to their central banks decisions and policies, a system that was effectively invented centuries ago and helped usher in Finance 1.0 a.k.a \u201cTraditional Finance.\u201d In the United States the central bank is the Federal Reserve <\/a>(or just \u201cThe Fed\u201d), in China it\u2019s the People\u2019s Bank of China<\/a>, and in Sweden it\u2019s the Sveriges Riksbank<\/a> \u2014 originally founded in 1668.<\/p>\n

The original employees of the Sveriges Riksbank would be amazed to visit the 21st Century today and see how much hasn\u2019t<\/em> changed with Finance 1.0. In fact, they would instantly recognize their traditional mix of a centralized banking system that manages the circulation of the national fiat currency \u2014 government-issued money that isn\u2019t backed by something like gold.<\/p>\n

Finance 1.0 kept things moving, but it has plenty of problems. With roots in the 1600\u2019s, it\u2019s a system built on a long-obsolete set of organizing principles \u2014 rules now seriously out of sync with the hyperconnected, extremely interdependent economics of the 21st Century. Finance 1.0 is a slow-moving method of defining, allocating, and using money\/credit\/value\/wealth that\u2019s no longer a fit for today\u2019s light-speed economics.<\/p>\n

Over time, Finance 1.0\u2019s shortcomings became easier to see, especially for people and businesses who want to work efficiently together in our global economy. Slow transactions, high fees, the possibility of human error, and complex cross-border transactions, are just a few of legacy finance\u2019s hazards. Not to mention the very real danger of theft, as well as sudden changes in government sanctions and regulations.<\/p>\n

Finance 2.0: Fintech Comes Next<\/strong><\/h2>\n

Finance 1.0 laid the foundation. Fintech \u2014 finance + tech \u2014 finally followed to form Finance 2.0.<\/p>\n

Fintech leverages the 20th Century\u2019s huge technological leaps, converged to enable money\u2019s next major shift. Computers became exponentially smaller and more powerful, Internet connectivity flourished, cellular networks gained bandwidth, and mobile devices got more affordable and sophisticated.<\/p>\n

All these gains drove Fintech, developing the next generation of apps and services for mobile banking, investing, and lending. Have you ever paid a friend with Venmo<\/a>, or seen an ad for Rocket Mortgage\u2019s<\/a> online application?<\/p>\n

That\u2019s Fintech\/Finance 2.0 in action, and it led to the mass adoption of centralized user-friendly stock trading platforms like Robinhood<\/a> and eToro<\/a>, or Revolut\u2019s<\/a> all-encompassing personal financial planning app. Finance 2.0 modernized Finance 1.0 by digitizing banking systems, and connecting buyers and sellers of all kinds to payment providers like Stripe<\/a>.<\/p>\n

These are tools we\u2019re all familiar with, that we hear about every day. Finance 2.0 brought on a lot of big advances \u2014 so what\u2019s the problem?<\/p>\n

It\u2019s true that Fintech allows millions of Millennials and Gen Z investors to easily access the stock market. But Fintech also has many structural flaws, and as those have come to light they\u2019ve led to movements like WallStreetBets<\/a> (WSB), a forum on Reddit where people discuss stock and options trading \u2014 often with the goal of questioning Wall Street rules as they pursue profits.<\/p>\n

Robinhood selling information<\/a> about its users\u2019 stock market activities to the financial services giant Citadel Securities<\/a> may have allowed hedge funds to front-run<\/a> (trade ahead of a significant price change) retailers, a sure sign that Finance 2.0\u2019s goals of democratizing access to financial markets is flawed.<\/p>\n

This came after WSB members banded together to organize a short squeeze<\/a> (a sharp stock price increase that forces traders who bet the stock price would fall to quickly buy the stock to prevent even more losses) in Citadel\u2019s short position<\/a> (a bet that a stock price will go down) in GameStop. It was a fast-paced sequence of events that caused several hedge funds to lose $19 billion in total<\/a>.<\/p>\n

To cap it off, Robinhood and other brokerages limited the trading of GameStop<\/a> and other similarly shorted stocks for several days. It was an essential maneuver to keep themselves in business, as well as satisfy regulators, even if it meant infuriating their users and appearing to run counter to their stated purpose of providing equal access to the stock market.<\/p>\n

The chaos showed that Finance 2.0 is not as well organized, predictable, and \u201cbug-free\u201d as everyone thought it was. Social media was able to disrupt, at least temporarily, wealthy Wall Street institutions and create huge losses for some blindsided institutional investors. While a forum on Reddit isn\u2019t going to single handedly take down Citadel Securities, with $35 billion assets under management (AUM), the GME drama shows change is coming.<\/p>\n

Yesterday\u2019s finance cannot power tomorrow\u2019s prosperity. Bailouts, taxes, nationalization, and regulations dominate the news. These measures can temporarily limit the negative economic impact of disasters like the COVID pandemic. But what they\u2019re not doing is building a more efficient, productive, and effective financial system.<\/p>\n

\n

Let\u2019s reimagine finance for the 21st century. Here\u2019s why \u2014 and how.<\/h1>\n<\/blockquote>\n

Finance 3.0: The Revolution<\/strong><\/h2>\n

This is where things finally start to open up: Finance 3.0 is the open financial system, where the decentralized finance of DeFi becomes a reality. It goes beyond Fintech to provide more controls that empower its users. DeFi takes out the middleman, while eliminating fees, charges, and penalties.<\/p>\n

\n

Finance 3.0 is what\u2019s called a \u201cpermissionless\u201d system.<\/h1>\n<\/blockquote>\n

It\u2019s independent of borders and communities, and doesn\u2019t require anyone\u2019s approval for participation. That\u2019s a very different idea for finance, which has earned its reputation for putting up barriers to taking part, especially as the rewards get bigger.<\/p>\n

The ideal engine to power Finance 3.0 is blockchain technology<\/a>, a time-stamped series of data records that is decentralized \u2014 managed by a global network of computers without a single owner, the records on a blockchain are almost impossible to change. The most famous example of blockchain in action is Bitcoin<\/a>, which has benefited from blockchain\u2019s unprecedented approach to scalability, transparency, and security.<\/p>\n

The vision of a more fair and transparent Web dates back to around 2006, but the tools and technologies weren\u2019t available then for it to materialize. Bitcoin was still three years off, bringing with it the notion of blockchain\u2019s distributed ledger for peer-to-peer digital storage. Decentralization was the idea; blockchain was the means. It led to human-centered finance \u2014 Finance 3.0.<\/p>\n

So what happens when finance becomes human-centered? Some key highlights:<\/p>\n

No central point of control<\/strong>: Middlemen are removed from the equation. Blockchains like Ethereum<\/a> provide a trustless platform (i.e. one whose encryption and protocols mean that trust is not required between participants \u2014 they can trust in the code<\/a>). The rules are unbreakable and data is fully encrypted.<\/p>\n

Central banks do not control transactions in Finance 3.0. No government or regulator will have the ability to freeze accounts and assets, as long as they can\u2019t steal the private keys to your crypto wallet.<\/p>\n

For example, in the DeFi cryptocurrency exchange Uniswap<\/a>, anyone who wants to<\/a> can list any ERC20<\/a> token (a type of Ethereum-based cryptocurrency) for sale. You can do this in a trustless manner that leaves you free to buy, trade, and swap it with other users \u2014 no bank, broker, or brokerage app needed. To many people, the decentralized flow of DeFi feels very liberating!<\/p>\n

Non-custodial<\/strong>: Finance 3.0 puts the user in complete control of their digital assets, if that\u2019s what they want. Instead of having to keep your cash or funds custodied in a bank account, you have a non-custodial option where you retain the ownership of your digital assets in your own non-custodial wallet<\/a>, with no third party involved. No one else can freeze or access your funds. For those who seek security against a bank or government seizing your accounts, non-custodial matters.<\/p>\n

Ownership of data<\/strong>: From central banks to tech giants like Amazon and Facebook, huge data centers are storing information on your income, credit cards, interests, dietary preferences, and much more. If you think it\u2019s just so they can improve their services, think again: marketers and advertisers pay billions each year for the data.<\/p>\n

In Finance 3.0, end users are regaining complete control of their data, thanks to the security of encryption. Information can be shared on a case-by-case, permissioned basis via cryptography techniques like the zero knowledge proof<\/a>%20is,the%20truth%20of%20verified%20property.) (ZPK), which allows one party to prove to another party that they know a particular fact, without revealing any other information besides that fact. ZPKs keep the information that must be shared between two parties to a minimum.<\/p>\n

Uninterrupted service<\/strong>: Account suspension and network attacks like distributed denial of service<\/a> are dramatically reduced. That\u2019s because there\u2019s no single point of failure in a decentralized system, so service disruption to accounts or networks will be minimal. In Finance 3.0, entire datasets are stored on distributed nodes to ensure redundancy, while multiple backups prevent server failure or seizure.<\/p>\n

Permissionless blockchains<\/strong>: Anyone can create an address and interact with the network. The power to access permissionless chains just can\u2019t be overstated: Users cannot be barred on account of geography, income, gender, orientation, or other sociological and demographic factors. Wealth and other digital assets can be transferred cross-border, quickly and efficiently, worldwide.<\/p>\n

How Does DeFi Work?<\/strong><\/h2>\n

Like any emerging technology, Finance 3.0 and its child DeFi are still being refined. For access to DeFi, people will only need a seed phrase<\/a> \u2014 a single password asset which enables their interaction with decentralized apps (dApps) and other services. Individuals will still use a Web browser to access the Internet, and visually these DeFi tools will be as user-friendly as the best of Finance 2.0.<\/p>\n

Your personal transition from 2.0 to 3.0 should feel like a gentle learning curve. But behind the scenes, the framework connecting you with digital services is complex: Transactions are signed and verified manually, to prevent platforms from siphoning away personal information without due cause. Web users opt in to DeFi platforms rather than trying \u2014 and often failing \u2014 to opt out.<\/p>\n

So, what are some things that are different in Finance 3.0?<\/p>\n
