The 51% attack in Zold can only include deleting certain transactions, since they are protected by the RSA signatures. All in one, this can reduce the total amount of zold in a wallet by removing certain transactions nor deleting the emission transactions which will completely erases the zold count. It is also possible to change the ownership of the zold root wallet, by providing a totally new identity. This can allow the attacker to get full control of the emissioned zold zents.

This would be a nice addition to the current paragraph.
