Blockchain, Antiquities, and Novel Economic Models of Restitution

In this talk Prof. Amy Whitaker discussed designing novel economic and contractual systems using blockchain to help with cases of restitution of art and culture

Agent-based modeling of Execution Tickets

Execution Tickets are currently debated as one of the most promising approaches to streamline incentives at protocol level. We created a holistic overview of potential mechanism designs and implementing an agent-based model to realistically compare different mechanism designs and identify potential drawbacks early on. The agent-based modeling approach is presented together with the results.

Tokenization and Fantasy Sports Platform

In this talk, Michael Zhao and Ilari Paasivirta presented their project on money tracking within Dream11, a fantasy sports platform

Bitcoin Staking, Overview of the Babylon Protocol

In this talk we discussed the main mechanisms behind the Babylon Protocol, functionalities and implications for the Bitcoin Ecossystem.

Liquid Staking Protocols

In this session, we discussed Liquid Staking Protocols and how these various designs aim to address the scaling problem of L1. We particularly focused on factors contributing to efficiency gains (such as reduced decentralization, transaction bundling, decreased congestion, and off-chain computation) and how these measures will impact transaction fees and the long-term stability of the platforms.

Relative Pricing and Efficient Allocation in Blockchains

In this meeting, Prof. Abdoulaye Ndiaye presented his paper "Relative Pricing and Efficient Allocation in Blockchains".

On the Viability of Open-Source Financial Rails, Economic Security of Permissionless Consensus

In this meeting, Prof. Jacob Leshno presented his recent paper with Prof.Rafael Pass and Prof. Elaine Shi, "On the Viability of Open-Source Financial Rails, Economic Security of Permissionless Consensus".

Multi-block MEV

In this meeting we dicussed the implications of Maximal Extractable Value (MEV) over a sequence of blocks, how new strategies of MEV can arise under this scenario and how frequent this scenario can be.

Payment initiation and smart contracts

In this talk Alistair Milne (Loughborough University, UK) and Ka Kei Chan (Brunel University, UK) presented their draft paper, "Payment Initiation and Transaction Costs", exploring the choice in financial transactions between push initiation and pull initiation. The discussion also covered the role of pull initiation in the execution of smart contracts.

Recent Developments and Research on CBDCs

In this week session we discussed the development of Central Banks Digital Currencies, their usage, implementation and related topics. Two papers were used for our discussion.

Decentralized Identity and Decentralized Social Networks

This session we discussed recent advances in open-source protocols for decentralized identity and social networks, and their potential roles in response to cases where governments have banned social platforms.

Effects of Airdrops for user growth on blockchain platforms

In this session, Aviv Yaish presented his recent work on how airdrops can incentive user growth for blockchain platforms and how different type of users can play a role in the effects of airdrop distributions.

Maximal Extractable Value at L2 Blockchains

In this session we looked over recent analysis on Maximal Extractable Value over Layer 2 protocols

DeFi Transactions per network

In this session, we explored how each the DeFi enviroment for each blockchain would differentiate from each other in terms of transactions characteristics and how this differences were evolving.

I See You! Robust Measurement of Adversarial Behavior

The paper introduces a novel surveillance metric to measure manipulative behavior in multi-agent systems, specifically focusing on decentralized finance (DeFi) and blockchain systems, and demonstrates its effectiveness through a natural experiment conducted on the Uniswap DeFi ecosystem. This paper is presented by Matheus

Dynamic Pricing for Non-fungible Resources - Designing Multidimensional Blockchain Fee Markets

The research proposes a method for designing fee markets in public blockchains that efficiently price multiple non-fungible resources. It utilizes a dynamic pricing mechanism based on a network designer-specified loss function, aligning incentives between the network, users, and miners to enhance overall performance.

Some interesting findings about L2 Protocols and Stablecoins

The discussion covers Ethereum's recent scalability upgrade facilitating L2 solutions integration and examines empirical methods to identify reasons for failures in stablecoins.

Security of L2 platforms

In this session, we discussed how and to what extent L2 blockchains inherit security guarantees from L1 blockchains and what new security risks arise with L2 technology.

Business models of L2 platforms

On most L2 platforms, the transaction fees users pay consist of a fee for the verification of their transaction on the L2 network and a fee to publish its proof on the L1 network. Since the L1 fees depend on congestion at the time the proof of an L2 transaction bundle is published on the L1, L2 platforms can generate profits if the fees they charge surpass their operational costs and the L1 fees they pay. In this session, we discussed under what circumstances an L2 platform can establish a viable business model.

Architecture of L2 platforms

In this session, we discussed different L2 architectures and how these various designs aim to address the scaling problem of L1. We particularly focused on factors contributing to efficiency gains (such as reduced decentralization, transaction bundling, decreased congestion, and off-chain computation) and how these measures will impact transaction fees and the long-term stability of the platforms.

Blockchain Price vs.Quantity Controls

This paper proposes a new transaction fee mechanism for blockchain platforms like Ethereum. This paper is presented by Prof. Abdoulaye Ndiaye (NYU)

Informational Efficiency of Cryptocurrency Markets

This paper investiagtes the impact of regulatory compliance on the liquidity of cryptocurrencies. This paper is presented by Prof. Mariia Petryk (GMU)

Decentralized Platform Generativity

This paper delves into the underexplored realm of decentralized platforms, such as blockchains, contrasting them with centralized counterparts in terms of their impact on innovation dynamics. It uncovers how transaction validators and platform design intricacies shape generativity and network effects, enriching our comprehension of developer engagement and network dynamics in decentralized environments. This paper is presented by Prof. Aija Leiponen (Cornell)
