Are multiple node implementations required for decentralization?

Maintaining multiple node implementations requires more work and is definitely not the most efficient way for a network to operate. It can open new attack vectors and it does not seem to be helpful against corruption. Please reply with an argument for or against.

Ledger nano secret wallet question

Hello i want to ask if someone knows if the second wallet you create with the 25th word passphrase is somehow linked to the first wallet in any way, shape or form?

I understand that im creating a totaly new wallet on the blockchain, so in that regard it wont be linked i suppose but what im more directly asking is if it leaves some type of trace or link with the original wallet for someone on the outside to look because its running on the same Trezor nodes, or using the base 24 word setup, or what ever really.

anyone care to elaborate this matter for me :)

The Brilliant Satoshi Nakamoto responded to Quantum Computer FUD 11 years ago

“SHA-256 is very strong. It's not like the incremental step from MD5 to SHA1. It can last several decades unless there's some massive breakthrough attack.”
“If SHA-256 became completely broken, I think we could come to some agreement about what the honest block chain was before the trouble started, lock that in and continue from there with a new hash function.”

And keep in mind that this is worst case situation, as if Quantum computers came unsuspectedly years earlier- I think lamport signature or other solutions could easily be implemented before any trouble comes.
