Audit-or-Cast: Enforcing Honest Elections with Privacy-Preserving Public Verification
Aman Rojjha, Gaurang Tandon, Varul Srivastava +1
Electronic voting systems must balance public verifiability with voter privacy and coercion resistance. Existing cryptographic protocols typically achieve end-to-end verifiability…
Optimal Strategies for Federated Learning Maintaining Client Privacy
Uday Bhaskar, Varul Srivastava, Avyukta Manjunatha Vummintala +2
Federated Learning (FL) emerged as a learning method to enable the server to train models over data distributed among various clients. These clients are protective about their data…
Towards Rational Consensus in Honest Majority
Varul Srivastava, Sujit Gujar
Distributed consensus protocols reach agreement among players in the presence of adversaries; different protocols support different values of . Existing works study this…
Centralization in Proof-of-Stake Blockchains: A Game-Theoretic Analysis of Bootstrapping Protocols
Varul Srivastava, Sankarshan Damle, Sujit Gujar
Proof-of-stake (PoS) has emerged as a natural alternative to the resource-intensive Proof-of-Work (PoW) blockchain, as was recently seen with the Ethereum Merge. PoS-based blockcha…
No Transaction Fees? No Problem! Achieving Fairness in Transaction Fee Mechanism Design
Sankarshan Damle, Varul Srivastava, Sujit Gujar
The recently proposed Transaction Fee Mechanism (TFM) literature studies the strategic interaction between the miner of a block and the transaction creators (or users) in a blockch…
DECENT-BRM: Decentralization through Block Reward Mechanisms
Varul Srivastava, Sujit Gujar
Proof-of-Work is a consensus algorithm where miners solve cryptographic puzzles to mine blocks and obtain a reward through some Block Reward Mechanism (BRM). PoW blockchain faces t…
PRAGTHOS:Practical Game Theoretically Secure Proof-of-Work Blockchain
Varul Srivastava, Sujit Gujar
Security analysis of blockchain technology is an active domain of research. There has been both cryptographic and game-theoretic security analysis of Proof-of-Work (PoW) blockchain…
QuickSync: A Quickly Synchronizing PoS-Based Blockchain Protocol
Shoeb Siddiqui, Varul Srivastava, Raj Maheshwari +1
To implement a blockchain, we need a blockchain protocol for all the nodes to follow. To design a blockchain protocol, we need a block publisher selection mechanism and a chain sel…
