Privacy protection has been extensively studied in the current blockchain research field. As representations, Monero and Zerocash have realized completely anonymous and amount-hiding transactions. How...
We describe an efficient linkable ring signature scheme, compact linkable spontaneous anonymous group (CLSAG) signatures, for use in confidential transactions. Compared to the existing signature schem...

A ring signature scheme can be viewed as a group signa-
ture scheme with no anonymity revocation and with simple group setup.
A linkable ring signature (LRS) scheme additionally allows anyone to
