Decentralized derivatives are tokens that derive their value from an underlying asset's performance, the outcome of an event, or the development of any other observable variable. While the deterministic and decentralized execution of smart contracts does have its advantages, there is risk that something may go wrong. The dependencies can be reduced when the derivative contract uses multiple independent data sources. Collateralized Debt Positions. Consequently we have to assign the tokens once again to the owners of that protocol, who may potentially be further protocols. So, I am in no way arguing against composability or openness. The investors never lose control over their funds, can withdraw or liquidate them, and can observe the smart contracts' token balances at any point in time. Another approach is to consolidate liquidity reserves through a smart contract that allows large liquidity providers to connect and advertise prices for specific trade pairs. To illustrate the concept, let us use the example of MakerDAO, a decentralized protocol that is used to issue the USD-pegged Dai stablecoin. We call a derivative event-based when its price is a function of any observable variable that is not the performance of an asset. Transparency. Vogelsteller, Fabian and Buterin, Vitalik. You don’t have to look back too far to find examples of what can happen when complexity gets in the way of transparency – and I truly believe we should learn from what went wrong in traditional financial markets. A popular derivative token platform is called Synthetix (Brooks et al., 2018). The research panel was headed by Dr. Fabian Schar – professor for Distributed Ledger Technologies and FinTech at the University of Basel. Potential attack vectors include flawed or misleading question specifications, incomplete outcome sets that may render the event unresolvable, and the choice of unreliable or fraudulent resolution sources. This flexibility allows for an ever-expanding range of possibilities and unprecedented interest in open financial engineering. Collateralized Debt Markets. Additionally, token transfers are much faster than any of the transfers in the traditional financial system. If the borrower fails to repay the debt, or if the collateral's value falls below the 150 percent threshold, where the full collateralization of the loan is at risk, the smart contract will start to liquidate the collateral at a potentially discounted rate. Let us start with a very simple example. 2017; https://0x.org/pdfs/0x_white_paper.pdf. Additionally, one can use off-chain indexers for peer discovery. Fabian Schar: DeFi Is Transparent, Unless You Look Closely - CoinDesk. The unprecedented speed of financial innovation in DeFi is exciting, and the space is home to some of the smartest people I know. Instead, the cryptoassets are locked up in a smart contract. We need more researchers in the space. Set Protocol is mainly designed for semi-automated strategies with deterministic portfolio rebalancing triggered by predefined threshold values and timelocks. I am also not talking about centralization creep, admin keys, oracle dependencies or highly concentrated governance token holdings. The cDai tokens are subsequently moved to the UniSwap ETH/cDai liquidity pool, along with some ETH, allowing the person to withdraw UNI-cDai tokens representing a share of the liquidity pool. Stay current with brief essays, scholarly articles, data news, and other information about the economy 2018; https://medium.com/marbleorg/introducing-marble-a-smart-contract-bank-c9c438a12890. If the keyholders do not create or store their keys securely, malicious third parties could get their hands on these keys and compromise the smart contract. Here, the price is determined by an inverse function of the underlying assets' performance within a given price range. "Bancor Protocol: Continuous Liquidity and Asynchronous Price Discovery for Tokens Through Their Smart Contracts; aka 'Smart Tokens.'" Professor Fabian Schär teaches distributed ledger technologies and is the managing director of the Center for Innovative Finance at the Faculty of Business and Economics at the University of Basel. Theoretical transparency does not necessarily correspond to actual transparency. MakerDAO has recently switched to a multi-collateral system, with the goal to make the protocol more scalable by allowing a variety of cryptoassets to be used as collateral. While the inherent transparency of DeFi is a deterrent to this use case, the network's pseudonymity may provide some privacy. Atomic swaps, autonomous liquidity pools, decentralized stablecoins, and flash loans are just a few of many examples that show the great potential of this ecosystem. It is important to point out that smart contract-based liquidity pools are not reliant on external price feeds (so-called oracles). 2018; https://github.com/ethereum/EIPs/blob/master/EIPS/eip-721.md. Although most people would not call these locking scripts a smart contract, they achieve similar goals in terms of the blockchain's custodial capabilities. 65-71. Fiat on- and off-ramps are the interface to the traditional financial system. On the one hand, pseudonymity can be abused by actors with dishonest intentions. etherscan.io/tokens, accessed January 22, 2021. In a current analysis paper printed within the Federal Reserve Bank of St. Louis Review, I argued that “DeFi has the potential to create a truly open, transparent and immutable financial infrastructure.” The unprecedented velocity of economic innovation in DeFi is thrilling, and the house is house to a number of This may create large meta protocols whose token holders essentially control a considerable portion of the DeFi infrastructure. The newly created tokens are essentially fully collateralized loans that do not require a counterparty and allow the user to get a liquid asset while maintaining market exposure through the collateral. Martinelli, Fernando and Mushegian, Nikolai. His research focus is on public Blockchains and DeFi protocols. 2019; https://balancer.finance/whitepaper/. Instead of creating new tokens, it is also possible to borrow existing cryptoassets from someone else. Efficiency. A complete set of sub-tokens consists of 1 sub-token for each potential outcome. "Havven: A Decentralised Payment Network and Stablecoin." All of these implementations are limited to ERC-20 tokens and Ether. According to Schär, DeFis exist in five layers: settlements, assets, protocols, applications and aggregators. In the case of a crisis, the availability of historical (and current) data is a vast improvement over traditional financial systems, where much of the information is scattered across a large number of proprietary databases or not available at all. 1997; https://nakamotoinstitute.org/the-idea-of-smart-contracts/. The higher the underlying volatility, the larger the risk of falling below a given collateralization ratio. Some of the most popular ones are Aave (Boado, 2020), Compound (Leshner and Hayes, 2019), and dYdX (Juliano, 2017). Fabian Schär, a professor at the University of Basel who specializes in distributed ledger technologies and fintech, writes in the paper that while DeFi is still a niche and small market, the industry is growing fast.. It uses a multi-stage resolution and disputing process that should minimize the dependency on a single reporting source as much as possible. Operational Security. The number of tokens that can be created depends on the target price of the tokens generated, the value of the cryptoassets that are being used as collateral, and the target collateralization ratio. In exchange, MKR holders assume the residual risk of extreme negative ETH price shocks, which may lead to a situation in which the collateral is insufficient to maintain the USD peg. Yearn Vaults are collective investment pools designed to maximize yield for a given asset. To be able to create these tokens, the person must lock cryptoassets in a smart contract. 4 UTXO-based blockchain implementations such as Bitcoin allow sophisticated unlocking conditions through their scripting language. St. Louis, MO 63102, Fabian Schär, In a recent research paper published in the Federal Reserve Bank of St. Louis Review, I argued that “DeFi [decentralized finance] has the potential to create a truly open, transparent and immutable financial infrastructure.”. Any two or more pieces can be integrated, forked, or rehashed to create something entirely new. Although DeFi could provide traditional financial services in a "more open, interoperable, and transparent way," Schär notes that DeFi is still a "niche market with certain risks." I am afraid that we have barely scratched the surface. CoinMarketCap. Subsequently, they call a contract function to create and withdraw a certain number of Dai and thereby lock the collateral. Collateralized loan platforms exist in three variations: Collateralized debt positions, pooled collateralized debt markets, and P2P collateralized debt markets. If the token holders do not agree with the designated reporter, they may start a dispute, which should eventually lead to the correct outcome. These keys allow a predefined group of individuals (usually the project's core team) to upgrade the contracts and to perform emergency shutdowns. 1994; http://www.fon.hum.uva.nl/rob/Courses/InformationInSpeech/CDROM/Literature/LOTwinterschool2006/szabo.best.vwh.net/smart.contracts.html. Under certain circumstances, these prediction markets may serve as decentralized oracles for the likelihood of a future outcome. To really understand how everything is connected, one would have to look far beyond the transaction level, analyze internal calls and aggregate the dependencies in a macro model. It lays the foundation for the discussion in Section 4. 2013; https://blockchainlab.com/pdf/Ethereum_white_paper-a_next_generation_smart_contract_and_decentralized_application_platform-vitalik-buterin.pdf. 7 For example, such a token was created in regard to the outcome of the recent U.S. presidential election. Consequently, the lender will only start to earn interest once there is a match. A paper published by the Federal Reserve Bank of St Louis has delved into the expansion of decentralized finance and Ethereum’s role in it. "A Next-Generation Smart Contract and Decentralized Application Platform." I used to be quite optimistic that DeFi could improve on the status quo and have spent significant portions of my early DeFi talks elaborating on why the cryptographic transparency may shape the future of finance. The former may provide exciting new possibilities and remove some dependencies, while the latter may essentially introduce the worst of two worlds, that is, de facto dependencies on a centralized operator with limited supervision. He is a member of the Center for Innovative Finance, which is a part of the University focused on financial technology. "Swap: A Peer-to-Peer Protocol for Trading Ethereum Tokens." See also: Jesus Rodriguez – When DeFi Becomes Intelligent. We need more researchers and better metrics in DeFi to fulfill the promise of a more robust and transparent financial infrastructure. 2019; https://www.augur.net/whitepaper.pdf. What I am saying is that composability in the absence of actual transparency can have devastating consequences. Blockchains face the ultimate trade-off between decentralization, security, and scalability. This ensures that tokens with the same underlying assets remain fungible; that is, redemption does not depend on the issuer. Each step increases the complexity, introduces additional dependencies and makes the token a little harder to analyze. While it is understandable that some projects want to implement these precautionary measures and remain somewhat flexible, the existence of these keys can be a potential problem. I am talking about the dark side of composability, the vast differences in theoretical and actual transparency and the potential for the amplification of systemic shocks. These "token on top of a token on top of a token" scenarios, which create wrapper tokens, can entangle projects in such a way that theoretical transparency does not correspond to actual transparency. In other words: For someone to be able to borrow ETH, there must be another person willing to lend ETH. In contrast to smart contract-based liquidity pools, with smart contract-based reserve aggregation, prices are not determined within the smart contract. The views expressed are those of the author(s) and do not necessarily reflect official positions of the Federal Reserve Bank of St. Louis or the Federal Reserve System. As an alternative, some projects rely on voting schemes, where the respective governance tokens grant their owners the right to vote on the protocol's future. UniSwap's liquidity pool (see Section 2.2) also has some characteristics of an on-chain investment fund. Prof. Dr. Fabian Schär is the Credit Suisse Asset Management (Switzerland) Professor for Distributed Ledger Technology and Fintech at the Faculty of Business and Economics, University of Basel. We end up with schemes that create tokens, on top of tokens, on top of tokens. 2018; https://hackmd.io/@HaydenAdams/HJ9jLsfTz. The problem becomes apparent when illustrated by an example. As such, DeFi may potentially create a genuinely open and accessible financial system. "The Tokenization of Assets: Using Blockchains for Equity Crowdfunding." There are a large variety of protocols that allow people to lend and borrow cryptoassets. Alternatively, the core team members themselves may be malicious or corrupted by significant monetary incentives.

Although DeFi could provide traditional financial services in a "more open, interoperable, and transparent way," Schär notes that DeFi is still a "niche market with certain risks." 2017; https://whitepaper.io/document/52/bancor-whitepaper. All transactions are publicly observable, and the smart contract code can be analyzed on-chain. 1-16; https://doi.org/10.20955/r.2018.1-16. The constant product model creates the incentives for a semi-automatic rebalancing of portfolio weights, while the trading fees generate passive income for the investors. "Set: A Protocol for Baskets of Tokenized Assets (v1.2)." The rules (smart contract code) and actions (transactions) are publicly available, and some additional meta-information (events) may help an observer to make sense of the data. As a countermeasure, reserve aggregation protocols usually have some (centralized) control mechanisms, such as maximum prices or a minimum number of liquidity providers. There is a large variety of lending protocols. Fabian Schär is a professor at the University of Basel and the managing director of the University’s Center for Innovative Finance. The leader in blockchain news, CoinDesk is a media outlet that strives for the highest journalistic standards and abides by a strict set of editorial policies. DeFi applications are transparent. Smart contracts can have security issues that may allow for unintended usage, and scalability issues limit the number of users. The smart contract will allow the owner to withdraw their collateral once the debt is repaid. Prices are still negotiated P2P. Trinkler, Reto and El Isa, Mona. While flash loans can only be employed in applications that are settled atomically and entirely on-chain, they are an efficient new instrument for arbitrage and portfolio restructuring. Figure 5Weighted Dai Collateralized Debt Market Rates and the MakerDAO Stability Fee. As such, DeFi loans are completely permissionless and not reliant on trusted relationships. The observability and deterministic execution allow—at least in theory—an unprecedented level of transparency. Posted on 5th May 2021. A paper published by the Federal Reserve Bank of St Louis has delved into the expansion of decentralized finance and Ethereum’s role in it. These inverse tokens allow users to get short exposure to cryptoassets. Some DeFi applications allow users to create collateralized debt positions and thereby issue new tokens that are backed by the collateral. Prof. Dr. Fabian Schär: DeFi steht für «decentralized finance» – für «dezentrale Finanzdienstleistungen». Dependencies. "Melon Protocol: A Blockchain Protocol for Digital Asset Management." A paper published by the Federal Reserve Bank of St Louis has delved into the expansion of decentralized finance and Ethereum’s role in it.. 1 An alternative approach can be found here: https://medium.com/pov-crypto/ethereum-the-digital-finance-stack-4ba988c6c14b. "Smart Contracts." Leshner, Robert and Hayes, Geoffrey. We discuss these aspects in the following subsections. In the absence of vesting periods, malicious founders can pull the rug by dumping their entire token holding on a CFMM, causing a massive supply shock and undermining the project's credibility. This significantly decreases counterparty credit risk and makes financial transactions much more efficient. Federal Reserve Bank of St. Louis, A Short Introduction to the World of Cryptocurrencies, Decentralized Finance: On Blockchain- and Smart Contract-Based Financial Markets, https://medium.com/pov-crypto/ethereum-the-digital-finance-stack-4ba988c6c14b, https://github.com/aave/aave-protocol/blob/master/docs/Aave_Protocol_Whitepaper_v1_0.pdf, https://www.synthetix.io/uploads/havven_whitepaper.pdf, https://blockchainlab.com/pdf/Ethereum_white_paper-a_next_generation_smart_contract_and_decentralized_application_platform-vitalik-buterin.pdf, https://github.com/ethereum/EIPs/blob/master/EIPS/eip-721.md, https://www.setprotocol.com/pdf/set_protocol_whitepaper.pdf, https://whitepaper.io/document/52/bancor-whitepaper, https://compound.finance/documents/Compound.Whitepaper.pdf, https://github.com/Betoken/Whitepaper/blob/master/BetokenWhitepaper.pdf, https://whitepaper.io/document/43/kyber-network-whitepaper, http://www.fon.hum.uva.nl/rob/Courses/InformationInSpeech/CDROM/Literature/LOTwinterschool2006/szabo.best.vwh.net/smart.contracts.html, https://nakamotoinstitute.org/the-idea-of-smart-contracts/, https://github.com/melonproject/paper/blob/master/melonprotocol.pdf, https://github.com/ethereum/EIPs/blob/master/EIPS/eip-20.md, https://medium.com/marbleorg/introducing-marble-a-smart-contract-bank-c9c438a12890, https://ethereum.github.io/yellowpaper/paper.pdf, https://github.com/runtimeverification/verified-smart-contracts/blob/uniswap/uniswap/x-y-k.pdf. Yearn Vaults mitigate these issues by employing the knowledge of the masses and using collective action to split network fees proportionally among all participants. It is implemented so that the total debt pool of all participants increases or decreases depending on the aggregate price of all outstanding synthetic assets. Fabian Schär University of Basel ... DeFi still is a niche market with relatively low volumes – however, these numbers aregrowing rapidly. To protect the lender and stop the borrower from running away with the funds, there are two distinct approaches: First, credit can be provided under the condition that the loan must be repaid atomically, meaning that the borrower receives the funds, uses, and repays them—all within the same blockchain transaction. For Dai, the figure also includes the MakerDAO stability fee, which should always be the highest rate in the system. The contracts can assume the roles of custodians, escrow agents, and CCPs. In a recent research paper I have written together with Matthias Nadler, we analyzed these adjustments, computed ownership tables for many of the most popular DeFi tokens, and introduced the term “wrapping complexity,” which measures the average number of adjustment – or “wrapping” – steps for a given base token. Berentsen, Aleksander and Schär, Fabian. Buterin, Vitalik. With every additional smart contract, the potential risk of a bug increases. These so-called oracles introduce dependencies and may, in some cases, lead to heavily centralized contract execution. In contrast to other protocols, offers can be accepted exclusively by the parties who have been involved in the negotiation. Brooks, Samuel; Jurisevic, Anton; Spain, Michael and Wawrick, Kain. Berentsen, Aleksander and Schär, Fabian. Once the two parties agree on a price, the trade is executed on-chain via a smart contract. The research, penned by Dr. Fabian Schär and published on May 2, has taken a deep dive into the world of DeFi, hinting that if security concerns and risks can be […] When the token supply of either one of the two tokens approaches zero, its relative price rises infinitely as a result. Nevertheless, even when a launch is perceived as being relatively "fair," the actual distribution often remains highly concentrated. These financial service providers are regulated and may require background checks on the origin of the funds. Professor Fabian Schär teaches distributed ledger applied sciences and is the managing director of the Middle for Revolutionary Finance on the College of Enterprise and Economics on the University of Basel. DeFi also has certain risks, namely, smart contract execution risk, operational security, and dependencies on other protocols and external data. So essentially, this is a call to action. P2P matching means that the person who is providing the liquidity lends the cryptoassets to specific borrowers. "Compound: The Money Market Protocol." Escalating gas prices (transaction fees) and long confirmation times adversely affect the DeFi ecosystem and favor wealthy individuals who can conduct large trades. While this technology has great potential, there are certain risks involved. This may be a general problem; however, in the DeFi space it is more pronounced. 2019; https://www.setprotocol.com/pdf/set_protocol_whitepaper.pdf. Szabo, Nick. Research written by Dr. Fabian Schär and was published on May 2, deeply immersed in the world of DeFi, suggesting that if security risks and risks can be addressed, it can … CoinDesk is an independent operating subsidiary of Digital Currency Group, which invests in cryptocurrencies and blockchain startups. The research, penned by Dr. Fabian Schär and published on May 2, has taken a deep dive into the world of DeFi, hinting that if security concerns and risks can be addressed, it may lead to huge changes in the financial industry. Feng, Felix and Weickmann, Brian. Please consider using a different web browser for better experience. "A Short Introduction to the World of Cryptocurrencies." Adams, Hayden. Whenever someone invests in an on-chain fund, the corresponding smart contract issues fund tokens and transfers them to the investor's account. Figure 5 shows the asset-weighted borrowing and lending rates for Dai and ETH. We call a derivative token asset-based when its price is a function of an underlying asset's performance. Second, loans can be fully secured with collateral. Moreover, it may give some context to TVL (total value locked), a number that still receives a lot of attention, despite the widespread view that it is somewhat problematic and must be interpreted with great care. Decentralized loan platforms are unique in the sense that they require neither the borrower nor the lender to identify themselves. In many cases, it is tough to find answers to seemingly straightforward questions and the risk of data getting misinterpreted is considerable. 2020; https://github.com/aave/aave-protocol/blob/master/docs/Aave_Protocol_Whitepaper_v1_0.pdf. External Data. Thus, it remains to be seen if a truly decentralized blockchain can keep up with the demand and provide the foundation for an open, transparent, and immutable financial infrastructure. The same is true for the fund's fee schedule. DeFi uses smart contracts to create protocols that replicate existing financial services in a more open, interoperable, and transparent way. Event-based derivative tokens can be based on any objectively observable variable with a known set of potential outcomes, a specified observation time, and a resolution source.7 Anyone can buy a full set of sub-tokens for a given event by locking 1 ETH in a smart contract.
