Empirical research on content moderation is fundamentally constrained by the opaque deployment of moderation systems on major social media platforms. To this end, the recent emerge…
On Exercising Governance Power in Decentralized Autonomous Organizations
Vabuk Pahari, Balakrishnan Chandrasekaran, Johnnatan Messias +2
A decentralized autonomous organization (DAO) is a governance entity that allows its stakeholders to manage blockchain-based protocols through smart contracts. The DAO explicitly s…
There Will Be Spam: Characterizing State-Invariant Transactions and Speculative MEV
Vabuk Pahari, Johnnatan Messias, Christof Ferreira Torres
Blockchains rely on transparency and immutability to ensure trust, but these guarantees come at the cost of an ever-growing ledger that increasingly threatens decentralization by m…

A decentralized autonomous organization (DAO) is a governing entity that empowers its stakeholders (i.e., users who hold one or more of its tokens) to manage blockchain-based proto…
How Exclusive are Ethereum Transactions? Evidence from non-winning blocks
Vabuk Pahari, Andrea Canidio
We analyze 15,097 blocks proposed for inclusion in Ethereum's blockchain over an eight-minute window on December 3, 2024, during which 38 blocks were added to the chain. We classif…

Understanding Blockchain Governance: Analyzing Decentralized Voting to Amend DeFi Smart Contracts
Johnnatan Messias, Vabuk Pahari, Balakrishnan Chandrasekaran +2
Decentralized Autonomous Organizations (DAOs) have emerged as a novel governance mechanism in blockchain ecosystems, particularly within Decentralized Finance (DeFi). By enabling t…
Dissecting Bitcoin and Ethereum Transactions: On the Lack of Transaction Contention and Prioritization Transparency in Blockchains
Johnnatan Messias, Vabuk Pahari, Balakrishnan Chandrasekaran +2
In permissionless blockchains, transaction issuers include a fee to incentivize miners to include their transactions. To accurately estimate this prioritization fee for a transacti…
