This article introduces a method of hiding transaction amounts in
the strongly decentralized anonymous cryptocurrency Monero. Similar
to Bitcoin, Monero is a cryptocurrency which is distributed through
a proof of work ``mining'' process. The original Monero protocol
was based on CryptoNote, which uses ring signatures and one-time keys
to hide the destination and origin of transactions. Recently the technique
of using a commitment scheme to hide the amount of a transaction has
been discussed and implemented by Bitcoin Core Developer Gregory Maxwell.
In this article, a new type of ring signature, A Multi-layered Linkable
Spontaneous Anonymous Group signature is described which allows for hidden
amounts, origins and destinations of transactions with reasonable
efficiency and verifiable, trustless coin generation. The author would like to note that early drafts of this were publicized in the Monero Community and on the bitcoin research irc channel. Blockchain hashed drafts are available in \cite{Snoe}.
