  1. The basic method of maintaining anonymity is not having an association between the bitcoin address and the person’s identity.
  2. People could additionally generate new single use addresses, in order to further break the linking between transactions.
  3. The linking of the transactions to the owner would still be possible if the owner could be associated to his key

  1. What is the basic method of maintaining anonymity?

A. Creating multiple wallets with a variety of keys to keep out of the limelight, seperating/obscuring the public address of both sender and reciever within the cryptography and math code.

  1. What additional method does Satoshi suggest?

A. "As an additional firewall, a new key pair should be used for each transaction to keep them from being linked to a common owner.” - SN

  1. What weakness does this additional method have

A. "Some linking is still unavoidable with multi-input transactions,… “ -SN

  1. What is the basic method of maintaining anonymity? The public keys remain anonymous. The public key is public in that the public can see that someone is sending an amount to someone else, but without information linking the transaction to anyone.

  2. What additional method does Satoshi suggest? Additional firewall, a new key pair should be used for each transaction to keep them from being linked to a common owner.

  3. What weakness does this additional method have? Some linking is unavoidable with multi-input transactions, which reveal that the input was by the same owner, which could further reveal other transactions by the same owner.

  • keeping public keys anonymous.
  • Satoshi suggest: a new public key
  • additional method has a weakness that if the owner of a key is revealed, linking could reveal other transactions that belonged to that person.

  1. What is the basic method of maintaining anonymity?
    Privacy can still be maintained by breaking the flow of information in
    another place.
  2. What additional method does Satoshi suggest?
    By keeping public keys anonymous and therefor a new key pair
    should be used for each transaction to keep them from being linked to a common owner.
  3. What weakness does this additional method have?
    with multi-input transactions, the multi inputs expose the owner.

  1. Keeping your public keys secret maintains the anonymity and prevents the explicit link that can be made between you and your transaction history.

  2. Adding an addition layer of privacy by creating a new key pair for each transaction. This is suggesting you adopt single use addresses to transfer BTC. These are extra requirements for the user and can be seen as a limitation concerning user experience.

  3. The risk is that if the owner of a key is revealed, linking could reveal other transactions that belonged to the same owner.

1- The traditional banking model achieves a level of privacy by limiting access to information to the parties involved and trusted third party.
2- A new key pair should be used for each transaction to keep them from being linked to a common owner.
3- If the owner of the key is revealed.

Hi there!

  1. Keeping anonymity behind public key, public key only verifies the TX has made but does not reveal the person behind it.

2.Use new public key for every new TX.

  1. If multiple inputs are associated with one bitcoin transaction , this means that the amount being sent is coming from multiple bitcoin wallet addresses. Any bitcoin user can generate an almost infinite amount of wallet addresses, each of which can hold any amount of BTC .

1.Keep public keys anonymous to keep information in a transaction private,
2. An additional firewall is by having each transaction have a new key pair.
3.A major flaw in this method is that public keys can be discovered using UTXO linking.

  1. The basic method is by limiting access to information to the parties involved and the trusted third party.

  2. Satoshi’s additional method is to make the transactions public but keep the identities of the involved anonymous. As an additional firewall, a new key pair should be used for each transaction to keep them from being linked to a common owner.

  3. The weakness is that some identity linking is 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. A trusted thirdparty that gives the transaktion to the counterpart. Its not made public only the parties and the third party can see the identities and transaktions.
  2. Instead the flow of information is cut where identity ends and instead connects transaction to be viewed publicly on the blockchain in this case.
  3. Risk are that the identity of the sender could be linked with multi input transactions, and if it does it could reveal other transactions that person has done that might be connected to dangorous things, which could end up in trouble for that person.
