RACED: Routing in Payment Channel Networks Using Distributed Hash Tables
Kartick Kolachala, Mohammed Ababneh, Roopa Vishwanathan
The Bitcoin scalability problem has led to the development of off-chain financial mechanisms such as payment channel networks (PCNs) which help users process transactions of varyin…
Off-chain Execution and Verification of Computationally Intensive Smart Contracts
Emrah Sariboz, Kartick Kolachala, Gaurav Panwar +2
We propose a novel framework for off-chain execution and verification of computationally-intensive smart contracts. Our framework is the first solution that avoids duplication of c…
Balance Transfers and Bailouts in Credit Networks using Blockchains
Lalitha Muthu Subramanian, Roopa Vishwanathan, Kartick Kolachala
In this paper, we propose a technique for rebalancing link weights in decentralized credit networks. Credit networks are peer-to-peer trust-based networks that enable fast and inex…
