Algorithmic Game Theory and Blockchains (Invited Talk)
Abstract
Algorithmic game theory has developed into a mature field over the past three decades. However, the emergence of blockchains has raised new fundamental questions at the intersection of computer science, economics, and game theory.

How Blockchain Tokens Are Changing Platform Economics (Invited Talk)
Abstract
Blockchain technologies are technologies inspired by Bitcoin, which emerged in 2008. Since then, many cryptocurrencies, altcoins, and other blockchain applications have emerged. For example, Ethereum introduced smart contracts, and with them came tokens, fungible tokens, non-fungible tokens, decentralized finance (DeFi), and decentralized autonomous organizations (DAOs). All these technologies can be grouped under the umbrella term "blockchain technologies."
Each new generation of blockchain technology promises decentralization, disintermediation, a level playing field for entry, and improved value creation and distribution. However, it is essential to examine to what extent and under what conditions blockchain technologies deliver on these promises. It turns out that sometimes they do, and sometimes they do not. This distinction is essential to apply blockchain technologies effectively for large-scale practical applications.
I focus here on blockchain-based cryptographic tokens and their impact on platform economics. Blockchain-based tokens, in conjunction with smart contracts, allow for new design choices in platforms. Therefore, I explore how these new design choices may help solve old problems in platform economics.

1DLT: Rapid Deployment of Secure and Efficient EVM-Based Blockchains
Abstract
Limited scalability and transaction costs are some of the critical issues that hamper a wider adoption of distributed ledger technologies (DLTs). That is particularly true for the Ethereum [Wood, 2014] blockchain, which, so far, has been the ecosystem with the highest adoption rate. Several solutions have been attempted in the last few years, most of which adopt the approach to offload transactions from the blockchain mainnet, a.k.a. Level 1 (L1), to a separate network. Such solutions are collectively known as Level 2 (L2) systems. While improving scalability, the adoption of L2 introduces additional drawbacks: users have to trust that the L2 system has correctly performed transactions or, conversely, high computational power is required to prove transactions’ correctness. In addition, significant technical knowledge is needed to set up and manage such an L2 system. To tackle such limitations, we propose 1DLT: a novel system that enables rapid deployment of an Ethereum Virtual Machine based (EVM-based) blockchain that overcomes those drawbacks.

Consistency of Automated Market Makers
Abstract
Decentralised Finance has popularised Automated Market Makers (AMMs), but surprisingly little research has been done on their consistency. Can a single attacker extract risk-free revenue from an AMM, regardless of price or other users' behaviour? In this paper, we investigate the consistency of a large class of AMMs, including the most widely used ones, and show that consistency holds.

Interest Rate Rules in Decentralized Finance: Evidence from Compound
Abstract
We study the fundamentals of interest rate rules on the decentralized finance protocol Compound. Interest rates are set by the governance of the protocol, and are based on the utilization of an asset: which is the ratio of a cryptocurrency that is borrowed to its total supply in the protocol. We discuss factors that determine the slope parameters of interest rate rules. Slope parameters are typically higher for more volatile cryptocurrencies. We argue liquidation risk can explain the cross-sectional variation in interest rate rules. We also draw parallels between these rules to the demand for loanable funds in traditional money markets.

Maximal Extractable Value (MEV) Protection on a DAG
Abstract
Many cryptocurrency platforms are vulnerable to Maximal Extractable Value (MEV) attacks [Daian et al., 2020], where a malicious consensus leader can inject transactions or change the order of user transactions to maximize its profit.
A promising line of research in MEV mitigation is to enhance the Byzantine fault tolerance (BFT) consensus core of blockchains by new functionalities, like hiding transaction contents, such that malicious parties cannot analyze and exploit them until they are ordered. An orthogonal line of research demonstrates excellent performance for BFT protocols designed around Directed Acyclic Graphs (DAG). They provide high throughput by keeping high network utilization, decoupling transactions' dissemination from their metadata ordering, and encoding consensus logic efficiently over a DAG representing a causal ordering of disseminated messages.
This paper explains how to combine these two advances. It introduces a DAG-based protocol called Fino, that integrates MEV-resistance features into DAG-based BFT without delaying the steady spreading of transactions by the DAG transport and with zero message overhead. The scheme operates without complex secret share verifiability or recoverability, and avoids costly threshold encryption.

Commit-Reveal Schemes Against Front-Running Attacks (Extended Abstract)
Abstract
We provide a game-theoretic analysis of the problem of front-running attacks. We use it to study a simple commit-reveal protocol and discuss its properties. This protocol has costs because it requires two messages and imposes a delay. However, we show that it prevents the most severe front-running attacks ("bad MEV") while preserving legitimate competition between users, guaranteeing that the earliest transaction in a block belongs to the honest user who values it the most ("good MEV").

The Demand for Programmable Payments: Extended Abstract (Extended Abstract)
Abstract
In [Kahn and Van Oordt, 2022], we examine the desirability of programmable payments, arrangements in which transfers are automatically executed conditional upon preset objective criteria. We study optimal payment arrangements in a continuous-time framework where a buyer and a seller of a service interact. We stack the cards in favor of programmable payments by considering an environment where neither agent has any legal recourse if the other fails to deliver upon their promises. We identify scenarios where programmable payments could improve economic outcomes and scenarios where they cannot. Direct payments increase the surplus by avoiding the liquidity cost of locking-up funds in a programmable payment arrangement until the moment where the conditions are satisfied to release those funds to the payee.
Programmable payments will be desirable, and may in fact be the only viable payment arrangement, in situations where economic relationships are of a short duration. Nonetheless, there is a limit to the length of the arrangement a single programmable payment can support, because eventually the additional liquidity cost of locking up more funds for a longer period starts to exceed the additional surplus generated from extending the length of the arrangement. For longer periods multiple payments are necessary.
Sufficiently long optimal chain-of-payments arrangements always start with direct payments because of the lower liquidity costs. Only towards the end of a relationship do the parties switch to the use of programmable payments. Moreover, the optimum for infinitely long payment arrangements consists of direct payments only. These results suggest that programmable payments are unlikely to become the new "standard" for all payment arrangements.
Many have argued that technological developments in the payments space will lead to an explosion of so-called micro-payments. Our results suggest a more complex relationship between transactions cost and the number of payments. Lower transaction costs increase the number of payments for the extensive margin in the sense of increasing the set of potential buyer-seller pairs where transaction costs are no longer prohibitively expensive. For the intensive margin, that is, within buyer-seller pairs, we find the opposite effect: lower transaction costs are associated with fewer payments, as trust becomes easier to achieve.
