Efficient Cross-Shard Transaction Execution in Sharded Blockchains
Sourav Das, Vinith Krishnan, Ling Ren
Sharding is a promising blockchain scaling solution. But it currently suffers from high latency and low throughput when it comes to cross-shard transactions, i.e., transactions tha…
Better Late than Never; Scaling Computation in Blockchains by Delaying Execution
Sourav Das, Nitin Awathare, Ling Ren +2
Proof-of-Work~(PoW) based blockchains typically allocate only a tiny fraction (e.g., less than 1% for Ethereum) of the average interarrival time~() between blocks for v…
Airmed: Efficient Self-Healing Network of Low-End Devices
Sourav Das, Samuel Wedaj, Kolin Paul +2
The proliferation of application specific cyber-physical systems coupled with the emergence of a variety of attacks on such systems (malware such as Mirai and Hajime) underlines th…
YODA: Enabling computationally intensive contracts on blockchains with Byzantine and Selfish nodes
Sourav Das, Vinay Joseph Ribeiro, Abhijeet Anand
One major shortcoming of permissionless blockchains such as Bitcoin and Ethereum is that they are unsuitable for running Computationally Intensive smart Contracts (CICs). This prev…
