  1. Keeping the public keys anonymous.
  2. Using a new public key for each transaction.
  3. Multi-input transactions would still constitute a link between different public keys so if the owner of one key becomes known, other keys would be exposed.

1 What is the basic method of maintaining anonymity?
To limit the access of information to involved parties.

2 What additional method does Satoshi suggest?
An additional method is to generate a new Key Pair for each transaction.

3 What weakness does this additional method have?
A potential disadvantage with this method is that where multi-input transactions are involved, this could reveal inputs relating to the same owner resulting in access to the history of transactions

1. What is the basic method of maintaining anonymity?
Keeping public keys anonymous; the public can see that a transaction has occurred, but without information linking the transaction to anyone.

2. What additional method does Satoshi suggest?
Using a new key pair for each transaction would avoid them from being linked to a common owner.

3. What weakness does this additional method have?
If the key owner is revealed, other transactions could be exposed as all the transactions are linked.

What is the basic method of maintaining anonymity?
The traditional model achieves a level of privacy by limiting access to information to involved parties and the trusted third party.

What additional method does Satoshi suggest?
By keeping the public keys anonymous, people can see that someone is sending an amount to someone else, but without information linking the transaction to anyone.

What weakness does this additional method have?
That if the owner of a key is revealed, the binding could reveal other transactions that belonged to the same owner.

  3. Some linking is still unavoidable with multi-input transactions, which necessarily reveal that their inputs were owned by the same owner. The risk is that if the owner of a key is revealed, linking could reveal other transactions that belonged to the same owner.

1: Anonymity is maint aĂźnĂ©e n’y gĂ©nĂ©rations public keys. The public can See ThĂ©rĂšse is a tans action but canot Tell The identity

2: By generating a New public key for each transaction

3: With Multi input transaction the Owner and The transactions could be Linked together and future transactions also Linked to The same owner

What is the basic method of maintaining anonymity?

From what I’ve gathered, the basic method, is leaving the centralized banking system be the middle man, verifying and controlling the flow of transactions and party information. and releasing very little to the public.

What additional method does Satoshi suggest?

It seems to me he adds the additional method of keeping the public keys private, you can see where the money is moving and where it came from and where its going, but not see who owns the sources of transactions on either end.

What weakness does this additional method have?

From what i understand, buy sending multi transactions, if the owner or creator of the transactions is identified, you could see all previous transaction made by the address and the owner linked to it.

1.Keeping public key anonymous so public can see Txs but without linking them to actual people.
2.another public key pair for each transaction to keem Txs from being link to owner.
3.multi-input Txs allow revealing their inputs were owned by the same owner so if the owner of key is revealed then other Txs of this owner are also revealed.

#96

  1. What is the basic method of maintaining anonymity?
    By having a private key, which only you knows, and a anonym public key basicly separates your identity from the Tx

  2. What additional method does Satoshi suggest?
    For each Tx you should use a different keypair

  3. What weakness does this additional method have?
    If someone finds out that you have multiple public keys it is easier for them to track you. This is possible when you are performing a transaction which requires an input greater than the singular inputs owned on the wallet

  1. The basic method of maintaining anonymity is to have all transactions public but to keep the keys anonymous. So it is open for all to see that ‘X’ sent a transaction but not to identify ‘X’ as a specific person or identity.
  2. An additional method is to use a new key pair for every transaction. It would be open for all to see that ‘X’, ‘Y’ & ‘Z’ all sent transactions, but are they three individuals or the same person three times? I think a practical implimentation of this is when I use my Ledger wallet, each time I send BTC there I get a new address. But when I send BTC to Celcius I use the same address over and over again. I also don’t want to use my personal computer to search the blockchain for transactions that have my public key, a smart person might assume that I could be searching myself and now my real identity through my IP address is linked to transactions that I would prefer to remain anonymous.
  3. A weakness of using new keys for each transaction is that multi input transactions reveal that there inputs were owned by the same person. Now if one key owner is revealed linking could reveal other transactions by the same owner.

  1. The basic method of maintaining anonymity is just keeping the public keys private. Basically when the signature is generated from UTXOs data and public key it creates some sense of anonymity as I understand.

  2. Satoshi suggest to generate the new key pair for each transaction to keep away info if tx was sent to the common owner.

  3. Owner and transaction can be linked together.

#99

  1. What is the basic method of maintaining anonymity? The basic method of anonymity is having a private key and keeping it private.

  2. What additional method does Satoshi suggest? Changing public key for ever new transaction, like on electrum wallet I think.

  3. What weakness does this additional method have? If the ID of a public key Owner is compromised previous transactions could be linked to them.

To maintain anonymity 
keep public keys anonymous
Additional method
 use a new key pair for each transaction to keep them
from being linked to a common owner.
What weakness does this method have
 the owner of a key is revealed, other transactions that belonged to owner could be revealed as well.

the same owner.
