Research direction

Start by reproducing Nethermind under Shadow and investigate the reported .NET CoreCLR failure and attempted membarrier and mlock system calls. Done means Nethermind can run with Shadow without these unsupported-runtime or syscall errors; the issue does not name specific files or tests to begin with.

Written by the indexing model from the issue text.

Description

Add support for the Nethermind execution layer client.

Current issue:
Nethermind outputs "Failed to create CoreCLR, HRESULT: 0x8007FF02", which is an error message reported by the .NET runtime.

Along with that, shadow reports that the unsupported membarrier and mlock systemcalls have been attempted to use.
