GPoS: Geospatially-aware Proof of Stake
Shashank Motepalli, Naman Garg, Gengrui Zhang +1
Geospatial decentralization is essential for blockchains, ensuring regulatory resilience, robustness, and fairness. We empirically analyze five major Proof of Stake (PoS) blockchai…
Decentralization in PoS Blockchain Consensus: Quantification and Advancement
Shashank Motepalli, Hans-Arno Jacobsen
Decentralization is a foundational principle of permissionless blockchains, with consensus mechanisms serving a critical role in its realization. This study quantifies the decentra…
Rorqual: Speeding up Narwhal with TEEs
Luciano Freitas, Shashank Motepalli, Matej Pavlovic +1
In this paper, we introduce Rorqual, a protocol designed to enhance the performance of the Narwhal Mempool by integrating Trusted Execution Environments (TEEs). Both Narwhal and Ro…
How Does Stake Distribution Influence Consensus? Analyzing Blockchain Decentralization
Shashank Motepalli, Hans-Arno Jacobsen
In the PoS blockchain landscape, the challenge of achieving full decentralization is often hindered by a disproportionate concentration of staked tokens among a few validators. Thi…
SoK: Decentralized Sequencers for Rollups
Shashank Motepalli, Luciano Freitas, Benjamin Livshits
Rollups have emerged as a promising solution to enhance blockchain scalability, offering increased throughput, reduced latency, and lower transaction fees. However, they currently…
Decentralizing Permissioned Blockchain with Delay Towers
Shashank Motepalli, Hans-Arno Jacobsen
Growing excitement around permissionless blockchains is uncovering its latent scalability concerns. Permissioned blockchains offer high transactional throughput and low latencies w…
