Oracles

An oracle is a bridge between the blockchain and the real world. They act as on-chain APIs you can query to get information into your smart contracts. This could be anything from price information to weather reports. Oracles can also be bi-directional, used to “send” data out to the real world. Oracles provide external data to smart contracts that operate on blockchain technology. They are essentially a form of communication between the outside world and the world of blockchain. Because blockchains and smart contracts are closed systems — where there are rigid processes for connecting...

Insurance and Risk on Defi

DeFi is a new line of business and by DeFinition a new risk sector with particular risks differing from the traditional financial sector and covering intangible risks. It will require modelling and correlation like other sectors but will have the advantage of real time granular data reducing the dependency of assumptions made in risk modelling. The following diagram shows the risk landscape as we perceive it traditionally pre DeFi evolution. This is a centralized model where intermediaries and third parties perform risk analysis to match the assets with liabilities. Much of DeFi has...

What Is Hedging?

The best way to understand hedging is to think of it as a form of insurance. When people decide to hedge, they are insuring themselves against a negative event’s impact on their finances. This doesn’t prevent all negative events from happening. However, if a negative event does happen and you’re properly hedged, the impact of the event is reduced. In practice, hedging occurs almost everywhere. For example, if you buy homeowner’s insurance, you are hedging yourself against fires, break-ins, or other unforeseen disasters. Portfolio managers, individual investors,...

Prediction Markets

Prediction markets allow users to monetise their ability to accurately forecast future events, trading contracts which pay out based on the results of these unknown events. Unlike public markets such as stocks or bonds, where bets are placed indirectly via the effects these outcomes are expected to have on asset prices, prediction markets enable users to bet directly on a piece of information that they believe is valuable. I.e., as opposed to participants betting on the outcome of an election by predicting which stock will rise and fall according to the outcome, prediction market users have...

Synthetic Asset

Synthetic assets, sometimes referred to as synths, are a combination of cryptocurrencies and traditional derivative assets. In other words, synths are tokenized derivatives. Synthetic assets are essentially tokenized derivatives. In the traditional financial world, derivatives are representations of stocks or bonds that a trader does not own but wants to buy or sell. In essence, if you want to profit from the price fluctuations of a stock that you don’t own, you can do this through a derivative. Synthetic assets, or tokenized derivatives, take this process one step further by adding...

What Are Liquidity Pools?

Liquidity pools enable users to buy and sell crypto on decentralized exchanges and other DeFi platforms without the need for centralized market makers. A liquidity pool is a crowdsourced pool of cryptocurrencies or tokens locked in a smart contract that is used to facilitate trades between the assets on a decentralized exchange (DEX). Instead of traditional markets of buyers and sellers, many decentralized finance (DeFi) platforms use automated market makers (AMMs), which allow digital assets to be traded in an automatic and permissionless manner through the use of liquidity pools. The...

What is lending and borrowing in DeFi?

Lending and borrowing, within the realm of traditional as well as crypto finance, entails the act of one party providing monetary assets — be it fiat or digital currencies — to someone else in exchange for a steady income stream. The concept of “lending and borrowing” has been around for ages and is one of the core aspects of any financial system, especially the “fractional banking” setup that is predominantly used across the globe today. The idea is extremely straightforward — i.e., lenders provide funds to borrowers in return for a regular interest rate, and that’s quite literally it....

Stablecoins

A stablecoin is cryptocurrency with a twist. Instead of being “mined” by an open, distributed network of computers performing a combination of math and record-keeping, a stablecoin derives its price from the value of another asset. In short, a stablecoin is pegged to some other underlying asset. What are the leading stablecoins? The most prominent stablecoins are the ones used for trading on crypto exchanges. These include: tether, the most popular stablecoin, which is usually in the top-five highest market caps for cryptocurrencies; USD coin, or USDC, an open-source project run...
