This paper is a Systematization of Knowledge (SoK) on Directed Acyclic Graph (DAG)-based consensus protocols, analyzing their performance and trade-offs within the framework of con…
Slipstream: Ebb-and-Flow Consensus on a DAG with Fast Confirmation for UTXO Transactions
Nikita Polyanskii, Sebastian Muller, Mayank Raikwar
This paper introduces Slipstream, a Byzantine Fault Tolerance (BFT) protocol where nodes concurrently propose blocks to be added to a Directed Acyclic Graph (DAG) and aim to agree…
A Review on Privacy in DAG-Based DLTs
Mayank Raikwar
Directed Acyclic Graph (DAG)-based Distributed Ledger Technologies (DLTs) have emerged as a promising solution to the scalability issues inherent in traditional blockchains. Howeve…
Fairness Notions in DAG-based DLTs
Mayank Raikwar, Nikita Polyanskii, Sebastian Müller
This paper investigates the issue of fairness in Distributed Ledger Technology (DLT), specifically focusing on the shortcomings observed in current blockchain systems due to Miner…
