The Geth code in question is referenced here. You might be able to set up a local NTP server to effectively manipulate the recorded time. | |
| May 11, 2021 at 9:03 | comment | added | Cheyenne Slager | Thanks for helping out. I indeed also found the sources you mention and was planning on using RAFT to demonstrate time manipulation. However, my question that still remains is: how can I control a node (in this case the leader) in order to make it return a specific time? Are there any tools or libraries available which enable you to enforce certain behavior upon specific nodes in the network? So far, I've looked at Truffle Suite and Hardhat, although I am not yet sure if these offer the functionality that I'm looking for. | |
