Blockchain Communication Vulnerabilities
Andrei Lebedev, Vincent Gramoli
Blockchains are diverse in the way they handle communications between their nodes to disseminate information, mitigate attacks, and agree on the next block. While security vulnerab…
On the Bandwidth Consumption of Blockchains
Andrei Lebedev, Vincent Gramoli
With the advent of blockchain technology, the number of proposals has boomed. The network traffic imposed by these blockchain proposals increases the cost of hosting nodes. Unfortu…
Stabl: Blockchain Fault Tolerance
Vincent Gramoli, Rachid Guerraoui, Andrei Lebedev +1
Blockchain promises to make online services more fault tolerant due to their inherent distributed nature. Their ability to execute arbitrary programs in different geo-distributed r…
On the Relevance of Blockchain Evaluations on Bare Metal
Andrei Lebedev, Vincent Gramoli
In this paper, we present the first bare metal comparison of modern blockchains, including Algorand, Avalanche, Diem, Ethereum, Quorum and Solana. This evaluation was conducted wit…
YAC: BFT Consensus Algorithm for Blockchain
Fedor Muratov, Andrei Lebedev, Nikolai Iushkevich +2
Consensus in decentralized systems that asynchronously receive events and which are subject to Byzantine faults is a common problem with many real-life applications. Advances in de…
Link Prediction using Top- Shortest Distances
Andrei Lebedev, JooYoung Lee, Victor Rivera +1
In this paper, we apply an efficient top- shortest distance routing algorithm to the link prediction problem and test its efficacy. We compare the results with other base line a…
