Either SPV or full node, your wallet has a same security.
i read a topic yesterday, which have the same security concerns about the SPV and full node wallet. i would like to mention it here, but let me quote other members too because they had also made the same statements.
Just to clarify, i have already mentioned in my reply that I know the limitation also. which means the same what you just discussed above, I do know, to run a full node you have to download the full blockchain which is more than 350 GB (roundabout) plus you need a better CPU with an internet connection. To make a full node wallet you do need some more ingredients in comparison to SPV wallets.. As mentioned by Helena Yu, the purpose of running a full node is helping the network and having more privacy.
And Yamane_Keto also does not agreed with my statement
wait WHATTT Where did you get the confidence to say this? SPV wallets are the same as full-node wallets, but they are lightweight that store block headers and Merkle roots,
First of all, let me tell you i was born confident, and i do have 100% confidence to say that SPV and the full node don't provide the same privacy and security features. Let me tell you all, that, I came to this statement due to this topic.
Due to the privacy limitations of SPV wallets like Electrum and Sparrow, in the case you use them connecting to public servers, I would like to know if there is a SPV wallet which does only rely on other nodes/servers to download block headers and certain groups of blocks to verify transactions myself, without sharing data like transaction IDs or addresses.
Maybe, I took the context of OP's post wrong here, but let me repeat it. I meant to say, SPV wallets do provide us with the key phrase, but what if the services behind that any SPV wallets got attacked and started to misbehave which could lose you money even if you have the seed phrase. Take an example of the latest hack on Atomic Wallet which caused a loss of around $35 million dollars. The point here is, if we do not own the wallet, then how can we be so sure and satisfied with that wallet amid the difference of open and close source? Because we own nothing they are also software made by some third parties. (maybe i am wrong here).
But full node wallets, are not made by any third parties because you configure the inbound and outbound network securities here. and also own the wallet too. (have you ever heard the hack of full node wallets? if yes, then what is the ratio here.)
You might forgive his misconception, am sure he meant it differently,
Not your keys, not your coin.
Are you agree with me?
because it's an encouraging point for me because others didn't agreed with my point, but your positive reply had increase my confidence about which Yamane_Keto had raised questions.
