Miner Revenue Maximization on Blockchain
PhD Qualifying Examination Title: "Miner Revenue Maximization on Blockchain" by Miss Togzhan BARAKBAYEVA Abstract: Miners in a blockchain ecosystem are incentivized with rewards for successfully generating and mining a new block. Transaction fees obtained from including transactions in the block constitute a significant part of the miner revenue. Therefore, maximizing transaction fees by forming an optimal block becomes a relevant problem. Although an approach was developed that increases miner revenue by 13.4% on Bitcoin, solving this for programmable blockchains, such as Ethereum, remains an open issue. In this work, we will review the method for Bitcoin and suggest an extension to Ethereum. Forming an optimal block in Bitcoin is equivalent to solving the dependencyconflict knapsack problem using a parameterized algorithm, where dependencies and conflicts among transactions are modeled as a graph. Since Ethereum introduces smart contracts and variable transaction fees based on gas usage, a thorough investigation of the differences between Bitcoin and Ethereum models is necessary. In addition, this work will review parameterized algorithms using treewidth, and discuss how data-dependency and information flow analysis can be utilized to identify transaction dependencies on Ethereum.
