Re: [Tails-dev] Fw: Electrum doc wrt. SPV security
To make sure I understand the consequences of this correctly, if I change my receiving address is there no way of linking it to the previous one? If someone used a single address for every transaction, anyone looking at the blockchain could link multiple payments to one identity. Electrum is a deterministic wallet that can generate an almost unlimited number of addresses. Simply stated, there is no way to link addresses generated from a seed. Electrum addresses look exactly the same as any other randomly generated address on the blockchain. Unfortunately, I am not familiar with Electrum's implementation of deterministic wallets, so I cannot reference specifics. Electrum delayed implementing the standard of hierarchical deterministic wallets (BIP 32) until version 2.0, but I am sure that it is similar.

For example, do my bitcoins have some kind of serial number for example? In that case, can the bitcoins I received on address A, be identified as the bitcoins I sent later on through address B?

Thanks, this is useful information. How do you suggest we convey the message to the user, without going too deep into technical details? (Still, it would be useful to have a URL to point them to for more info if they wish to.) For contributing to the documentation, surely our frontdesk has already pointed you to the relevant page, but just in case they forgot, here it is: https://tails.boum.org/contribute/how/documentation/ Cheers, ___ Tails-dev mailing list Tails-dev@boum.org https://mailman.boum.org/listinfo/tails-dev To unsubscribe from this list, send an empty email to tails-dev-unsubscr...@boum.org.
