OHIE: Blockchain Scaling Made Simple
Haifeng Yu, Ivica Nikolic, Ruomu Hou +1
Many blockchain consensus protocols have been proposed recently to scale the throughput of a blockchain with available bandwidth. However, these protocols are becoming increasingly…
Exploiting The Laws of Order in Smart Contracts
Aashish Kolluri, Ivica Nikolic, Ilya Sergey +2
We investigate a family of bugs in blockchain-based smart contracts, which we call event-ordering (or EO) bugs. These bugs are intimately related to the dynamic ordering of contrac…
Neuro-Symbolic Execution: The Feasibility of an Inductive Approach to Symbolic Execution
Shiqi Shen, Soundarya Ramesh, Shweta Shinde +2
Symbolic execution is a powerful technique for program analysis. However, it has many limitations in practical applicability: the path explosion problem encumbers scalability, the…
BesFS: A POSIX Filesystem for Enclaves with a Mechanized Safety Proof
Shweta Shinde, Shengyi Wang, Pinghai Yuan +3
New trusted computing primitives such as Intel SGX have shown the feasibility of running user-level applications in enclaves on a commodity trusted processor without trusting a lar…
Finding The Greedy, Prodigal, and Suicidal Contracts at Scale
Ivica Nikolic, Aashish Kolluri, Ilya Sergey +2
Smart contracts---stateful executable objects hosted on blockchains like Ethereum---carry billions of dollars worth of coins and cannot be updated once deployed. We present a new s…
