Decentralized Finance: On Blockchain- and Smart Contract-Based Financial Markets
The term decentralized finance (DeFi) refers to an alternative financial infrastructure built on top of the Ethereum blockchain. DeFi uses smart contracts to create protocols that replicate existing financial services in a more open, interoperable, and transparent way. This article highlights opportunities and potential risks of the DeFi ecosystem. I propose a multi-layered framework to analyze the implicit architecture and the various DeFi building blocks, including token standards, decentralized exchanges, decentralized debt markets, blockchain derivatives, and on-chain asset management ...

Beyond the Doomsday Economics of “Proof-of-Work” in Cryptocurrencies
This paper discusses the economics of how Bitcoin achieves data immutability, and thus payment finality, via costly computations, i.e., ?proof-of-work.? Further, it explores what the future might hold for cryptocurrencies modelled on this type of consensus algorithm. The conclusions are, first, that Bitcoin counterfeiting via ?double-spending? attacks is inherently profitable, making payment finality based on proof-of-work extremely expensive. Second, the transaction market cannot generate an adequate level of ?mining? income via fees as users free-ride on the fees of other transactions in a ...

Decentralized Finance (DeFi): Transformative Potential and Associated Risks
Financial services in the crypto finance world are provided by a combination of centralized finance (CeFi) organizations and decentralized finance (DeFi). CeFi's are roughly similar to traditional financial intermediaries, but DeFi seeks to provide services using smart contracts (computer code) rather than an intermediary. DeFi's unusual structure creates some interesting potential but also raises new risks in addition to those already inherent in blockchains and crypto finance. This paper reviews some of the opportunities and risks.

The Lightning Network: Turning Bitcoin into Money
The Lightning Network (LN) is a means of netting Bitcoin payments outside the blockchain. We find a significant association between LN adoption and reduced blockchain congestion, suggesting that the LN has helped improve the efficiency of Bitcoin as a means of payment. This improvement cannot be explained by other factors, such as changes in demand or the adoption of SegWit. We find mixed evidence on whether increased centralization in the Lightning Network has improved its efficiency. Our findings have implications for the future of cryptocurrencies as a means of payment and their ...

The Blockchain Revolution: Decoding Digital Currencies
Cryptocurrencies and decentralized finance have grown considerably since the publication of the white paper on bitcoin in 2009. This article presents an overview of cryptocurrencies, blockchain technology, and their applications, explaining the spirit of the enterprise and how it compares with traditional operations. We discuss money, digital money, and payments; cryptocurrencies, blockchain, and the double-spending problem of digital money; decentralized finance; and central bank digital currency.

An Introduction to Web3 with Implications for Financial Services
Web3 is used to describe the next iteration of the internet in which decentralized services are automated on blockchains. This paper describes the elements of Web3 including blockchains and tokens. It describes the largest decentralized finance protocols and some specific services where blockchain and tokens can be used. The paper concludes with a brief discussion of some regulatory challenges.
