Writing a e book on decentralized finance is a bit like describing a riddle, wrapped in a thriller inside an enigma, to borrow from Winston Churchill. First, one should summarize the origins of recent decentralized finance, then the mechanics of the blockchain know-how that gives the sector’s spine, and solely then do you arrive at DeFi’s infrastructure. All of it ought to be finished in 191 pages, too, together with glossary, notes and index. It’s not an endeavor for the faint of coronary heart.
Luckily, the authors of DeFi and the Way forward for Finance — Duke College finance professor Campbell Harvey, Dragonfly Capital common companion Ashwin Ramachandran, and Fei Labs founder Joey Santoro — had been as much as the duty. After recapitulating the “5 flaws of conventional finance” — inefficiency, restricted entry, opacity, centralized management and lack of interoperability — they go on to elucidate how DeFi improves upon the established order.
Take the issue of centralized management. Governments and enormous establishments maintain a “digital monopoly” over the cash provide, charge of inflation, in addition to “entry to the perfect funding alternatives,” wrote the authors. DeFi with its open protocols and immutable properties “upends this centralized management.”
As for a way DeFi solutions conventional finance’s opacity shortcoming: “All [DeFi] events are conscious of the capitalization of their counterparties and, to the extent required, can see how funds will likely be deployed,” which mitigates counterparty danger. As goes inefficiency, “A person can largely self-serve throughout the parameters of the sensible contract” in a decentralized utility by exercising a put choice, as an example.
What about conventional finance’s failing in restricted entry? DeFi offers underserved teams just like the world’s unbanked inhabitants direct entry to monetary companies, wrote the authors, providing yield farming for example, a DeFi course of the place customers are rewarded for staking capital within the type of a governance token that makes them, in impact, part-owners of the platform, “a uncommon incidence in conventional finance.”
The authors additionally described the ways in which DeFi protocols could be layered atop each other (i.e., DeFi’s composability, typically known as “DeFi Legos”), which helps to take care of the interoperability deficit. As soon as a base infrastructure has been established (to create an artificial asset, as an example), “any new protocols permitting for borrowing or lending could be utilized. The next degree would permit for attainment of leverage on prime of borrowed property.”
Taking a deep dive
Chapter 6 explores eight main DeFi protocols in depth: MakerDAO, Compound, Aave, Uniswap,Yield, dYdX, Artificial, and Set Protocol. Every part is accompanied with a really helpful desk, the place the primary column describes how conventional finance solves a specific downside, and the second column how a particular DeFi protocol offers with that downside.
For instance, in Desk 6.3, “Issues that Aave Solves,” the primary row offers with “centralized management.” Within the incumbent finance system, “borrowing and lending charges [are] managed by establishments,” whereas within the DeFi method, Column 2, “Aave rates of interest are managed algorithmically.”

Conventional finance gives solely “restricted entry” inside its legacy techniques. That’s, “solely choose teams have entry to massive portions of cash for arbitrage or refinance” (Row 2, Column 1), whereas throughout the Aave protocol, “flash loans democratize entry to liquidity for instantly worthwhile enterprises.”
The third row focuses on “inefficiency,” particularly “suboptimal charges for borrowing and lending as a result of inflated prices” in conventional finance, whereas Aave’s answer (Row 3, Column 2) is “algorithmically pooled and optimized rates of interest.”
Novel dangers
The authors had been cautious to remind readers that “all progressive applied sciences introduce a brand new set of dangers.” Within the case of DeFi, these are considerable, together with sensible contract, governance, oracle, scaling, DEX custodial, environmental and regulatory dangers.
“Software program is uniquely weak to hacks and developer malpractice,” the authors wrote, whereas current hacks of bZx and DForce “display the fragility of sensible contract programming.”
Amongst these new threats, “oracle danger” looms significantly massive. DeFi protocols require entry to correct, safe value data to make sure that actions resembling liquidations and prediction market resolutions work easily. “Essentially, oracles purpose to reply the easy query: How can off-chain information be securely reported on chain?” But, all on-line oracles as at the moment constituted “are weak to front-running, and tens of millions of {dollars} have been misplaced to arbitrageurs,” they wrote, including:
“Till oracles are blockchain native, hardened, and confirmed resilient, they characterize the most important systemic risk to DeFi right this moment.”
Elevating up “marginalized teams”
“This e book is essentially about monetary democracy,” co-author Harvey advised Cointelegraph. The e book’s preface, written by no much less a personage as Ethereum creator Vitalik Buterin, reminds readers that “monetary censorship continues to be an issue for marginalized teams,” particularly within the creating world — which is why DeFi is essential.
The typical reader would possibly discover this e book a bit heavy on the technical aspect, nonetheless. Graphics embrace superlinear and logistic/sigmoid bonding curves, for instance, which could go over some heads. Those that wish to find out how a flash mortgage truly works, although, will discover it helpful; the e book’s glossary is complete and useful.
DeFi: A complete information to decentralized finance
It will have been illuminating, nonetheless, to study extra about how DeFi was starting to truly change the world, resembling providing banking to the unbanked, or insurance coverage to the uninsured — although maybe that is past the scope of the e book.
One would possibly ask what proportion of the world’s “unbanked inhabitants” is definitely profiting from “yield farming,” a still-esoteric DeFi course of that the authors nonetheless cite for example of the way in which DeFi gives entry “to the various who want monetary companies however whom conventional finance leaves behind.” Not too many, one guesses.
Sadly, a lot of the main focus within the DeFi world right this moment nonetheless appears to be on methods to realize leverage or arbitrage between markets reasonably than fixing the issues of the worldwide poor. Nor does the e book commit a lot ink to defending DeFi from critics within the common enterprise press resembling The Wall Road Journal, which noted in September that DeFi was “bringing on line casino capitalism to the crypto plenty.”
That’s not the authors’ imaginative and prescient of the longer term. Quite the opposite, they see in DeFi “the scaffolding of a shining new metropolis. […] Finance turns into accessible to all. High quality concepts are funded irrespective of who you’re. A $10 transaction is handled identically to a $100 million transaction. Financial savings charges improve and borrowing prices lower because the wasteful center layers are excised. In the end we see DeFi as the best alternative of the approaching decade and stay up for the reinvention of finance as we all know it.”
These are worthy objectives, although unlikely to be realized within the rapid future. Till then, this e book ought to be of curiosity to anybody seeking to unravel DeFi’s interior workings.
