In a bitcoin context I know what a cold wallet is. For example with
https://bitkey.io/ you have have your actual wallet on a air gapped cold wallet and its private key will likely never get exposed if you use 2 PCs. I think it may even be more secure then a trezor or ledger and its totally free, but not as user friedly.
So for masternodes this concept of hot and cold wallets seems to be something entirely different, i not came across a true cold wallet when it comes to masternode guides. You have a master-node that you start from a hot wallet that run on a desktop, usually the masternode only needs the masternodes private key and is started remotely so they run cold.
Now I came across Ganjacoin and they want you to set privkey and txindex. On the masternode.
https://github.com/legends420/GCFORK/blob/master/install.sh Why does their masternode needs that as well, does this make it less secure does this expose something? I guess not but I just like to understand the technical part a bit. The masternode is still not a hot wallet I guess but how comes that its doing differently then the other coins I came across?
