My top 5 begin and end with
XC & XCurrency.
Why? See below:
Every XC wallet is automatically an Xnode and no balance needs to be held in it (aka, completely
decentralized).
Privacy Mode is on-chain, and breaks transactions into fragments and utilises
trustless mixing to forward fragments on to the recipient. (It's not a ring signature either; it's a unique m-of-m
multisig transaction.)
- Since every node forwards fragments, there's no telling whether a node is the originator or final receiver of a fragment. Therefore receiver/sender address is concealed.
- Since fragments are sent, there's no telling what the full amount of any given transaction is. Therefore the amount sent/received is concealed.
- Since trustless mixing is m-of-m multisig, no node can steal coins. They can either sign or opt out. (In the latter case, fragments are sent via spare nodes).
XC will soon be adding "
stealth addresses" to its arsenal. This will allow the receiver to publicise a receiving address, while payments sent to it will arrive in another address, prevent associating the receiver with amounts received.
Finally XC nodes can run as
TOR nodes, so that not only are their IP addresses concealed, but since they do not use exit nodes they're immune to packet sniffers.
As such, XC claims to be completely private. Sender address, receiver address, amount, and IP address are all kept private. Future developments will allow increasing control over degrees of privacy, enabling XC transactions to be flexible and tailored to a wide variety of use-cases.
In addition to completely anonymous transfers, XC has
XChat, instant p2p encrypted messaging (also available on the XC TOR Stick,
www.xcmerch.com). XC is also developing encrypted voice + video to be used across PC & mobile platforms.
