  1. What is the basic method of maintaining anonymity?

Satoshi suggest to eliminate third party and counterparty when considering anonymity by
keeping the public key anonymous. You will see that a tx has been sent but not necessarily from what person to what person so to speak.

  1. What additional method does Satoshi suggest?

A new public key for every tx so you can´t link one address and all its tx to a single owner.

  1. What weakness does this additional method have?

If someone s able to figure out the link between the public adress to a specific person you can backtrack and see to whom the person sent money since that adress was created.

  1. What is the basic method of maintaining anonymity?
    By keeping the public keys anonymous (only the signature is public)
  2. What additional method does Satoshi suggest?
    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 still unavoidable with multi-input transactions (multi UTXO, as my understanding), which necessarily reveal that their inputs were owned by the same owner. The risks that if the owner of a key is revealed, linking could reveal other transactions that belonged to the same owner.

1.)
The public can see that someone is sending an amount to someone else,
but without information linking the transaction to anyone

2.)
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 risk is that if the owner of a key is revealed, linking could reveal other transactions that belonged to the same owner.
