Introduction to Centralized Finance
Authors: Daniel Liebau
Introduces centralized finance in the blockchain ecosystem, including exchanges, custodians, brokers, and on/off-ramps.
Practitioner takeaway
CeFi may be the low-hanging fruit for financial institutions entering blockchain finance: faster settlement, tokenized securities, new product segments, and lower operational overheads. But cybersecurity, governance, regulatory uncertainty, volatility, wallet technology, and settlement delays all require serious management.
Retail CBDC and the Social Costs of Liquidity Provision
Authors: Dirk Niepelt
Analyzes retail CBDC design and its implications for payment systems, banks, central banks, and liquidity provision.
Practitioner takeaway
If CBDC becomes a cost-effective payment instrument, central banks may face pressure to introduce it and possibly pay interest on it. Banks and regulators then need to reassess business models, financial fragility, and deposit insurance. BigTech will be watching closely, too.
Conflicts of Interest and Market Failures in Unregulated Capital Markets: Evidence from ICO Analysts
Authors: Valerie Laturnus, Andreas Barth, Sasan Mansouri, and Alexander F. Wagner
Studies ICO analysts and shows why information intermediaries in lightly regulated markets need transparent incentives and credible track records.
Practitioner takeaway
Transparency among information providers is valuable far beyond ICOs. Founders should select analysts and advisors carefully, investors should look at analyst track records, and platforms should disclose affiliations and past interactions. Ratings given as favors may harm credibility more than they help fundraising.
Security Token Offerings: A New Frontier in Entrepreneurial Finance
Authors: Daniel Liebau
Explores security token offerings as a bridge between entrepreneurial finance, securities regulation, and blockchain infrastructure.
Practitioner takeaway
For issuers, token design matters: voting rights, realistic funding targets, and transparent disclosures can improve funding prospects. For investors, governance arrangements are key signals. For platforms and regulators, the task is to build infrastructure and rules for voting, dividends, disclosure, and programmable compliance.
Crypto Funds: A New Intermediary in Entrepreneurial Finance
Authors: Paul Momtaz
Looks at crypto funds as new intermediaries that can provide capital, credibility, liquidity, advice, and technical support to blockchain ventures.
Practitioner takeaway
Crypto funds can add value to blockchain startups, but they operate in volatile markets with transparency, cybersecurity, and regulatory challenges. Their positive impact depends on balancing innovation with oversight.
Understanding Retail Trading: Cryptocurrencies Versus Traditional Asset Classes
Authors: Marina Niessner
Compares retail trading in cryptocurrencies with trading behavior in traditional asset classes such as stocks and gold.
Practitioner takeaway
The same retail investors can use different mental models across asset classes: contrarian behavior in stocks, but momentum-like behavior in crypto. Asset managers and trading platforms may need crypto-specific risk tools, interfaces, and warnings. Regulators should not assume traditional investor-behavior models are enough.
Limits to Arbitrage for Blockchain-Based Assets
Authors: Stefan Voigt, Nikolaus Hautsch, and Christoph Scheuch
Explains why the same blockchain-based asset can trade at different prices across exchanges when settlement, custody, and operational frictions get in the way.
Practitioner takeaway
Trustworthy exchanges can create real value when settlement latency makes arbitrage costly. Investors may reduce counterparty risk by trading on reputable venues, while arbitrageurs need to model settlement latency explicitly. DEXs solve some problems, but introduce others - including front-running.
Introduction to Decentralized Finance
Authors: Simon Trimborn
Introduces DeFi as programmable financial infrastructure for trading, lending, borrowing, and other services without traditional centralized intermediaries.
Practitioner takeaway
DeFi can reduce transaction costs by replacing intermediaries with software, but smart contract risk, hacks, stablecoin dependence, and regulation matter. Business innovation teams should look for ways to blend DeFi with existing financial services so both sides can benefit.
Stablecoins: The Battleground for the Future of Payments
Authors: Christian Catalini
Explains stablecoin designs, reserve models, and their potential role in future payment infrastructure.
Practitioner takeaway
Entrepreneurs should look beyond reserve-interest models and build stablecoins into useful payment ecosystems. Banks should assess whether stablecoins enhance or disrupt their roles. Regulators should support sound local frameworks. Developers should prioritize fiat-backed designs, transparency, reserve quality, and compliance.
Automated Market Makers: A New Trading Paradigm
Authors: Agostino Capponi
Introduces AMMs as smart-contract based markets where users trade against liquidity pools instead of traditional order books.
Practitioner takeaway
Liquidity providers earn fees, but also face arbitrage losses, especially when token volatility is high. AMM design must balance price impact for regular users against arbitrage risk for liquidity providers. Dynamic fees and pricing curves may become important tools for resilient market design.
AMM Pricing Functions: Concepts and Challenges
Authors: Andreas Park
Goes deeper into the pricing rules that determine liquidity provision, price movement, and risk sharing in AMMs.
Practitioner takeaway
No AMM pricing rule is perfect. Constant product AMMs do not drive transaction costs to zero, while price-times-quantity approaches can create larger price impacts and depend heavily on settlement speed. Practitioners also need to plan for just-in-time liquidity and sandwich attacks.
Commitment Against Front-Running Attacks
Authors: Andrea Canidio and Vincent Danos
Examines commit-reveal mechanisms that can protect users from front-running in transparent blockchain transaction environments.
Practitioner takeaway
Commit-reveal protocols can protect users from front-running while preserving legitimate competition. A major practical point is that this can be implemented at the smart contract level without relying on third parties or changing the whole blockchain infrastructure. Better user protection can also become a competitive advantage.
Contagion in Decentralized Lending Protocols
Authors: Natkamon Tovanich, Myriam Kassoul, Simon Weidenholzer, and Julien Prat
Studies how interconnected DeFi lending pools can transmit stress through collateral, debt positions, and liquidation mechanisms.
Practitioner takeaway
DeFi platforms need system-wide risk monitoring. Interconnected pools can spread defaults quickly, especially around major assets such as ETH and stablecoins. Liquidity management, collateral strategies, stress testing, and governance mechanisms are essential for decentralized lending stability.
A Summary of Decentralized Finance
Authors: Dirk Zetsche, Douglas Arner, and Ross Buckley
Summarizes DeFi from legal, financial, and regulatory perspectives, focusing on how code, composability, and open infrastructure change financial services.
Practitioner takeaway
DeFi may decentralize one part of the value chain while reconcentrating power somewhere else - cloud, data, infrastructure, or interfaces. Regulators should identify new points of failure, strengthen RegTech, and adapt supervision to the architecture.
