Ethereum has been attracting lots of attacks, hence there is a pressing need to perform
timely investigation and detect more attack instances. However, existing systems suffer
from the scalability issue due to the following reasons. First, the tight ...

Smart contracts are programs deployed on a blockchain. They are executed for a monetary
fee paid in gas—a clear optimization target for smart contract compilers. Because smart contracts
are a young, fast-moving field without (manually) fine-tuned ...

I built a tool to help detect and defend against "metamorphic smart contracts," mutable blockchain code that poses a risk to web3 users.

Out-of-gas errors occur when smart contract programs are provided with inputs that

in…

Fuzz testing (fuzzing) has witnessed its prosperity in detecting security flaws recently.
It generates a large number of test cases and monitors the executions for defects.
Fuzzing has detected thousands of bugs and vulnerabilities in various ...

TLDR: There exist a financial incentive for the execution payload to be proposed later than the anticipated time window for it. We worry that this might lead to favoring larger validators, encourag...
