Here is an improved version of the cloakcoin explanation:
Why is CLOAKCOIN cool?Cloakcoin provides a fast, fully private, secure, untraceable and user friendly transaction system with guaranteed fungibilty (all coins being equal and interchangeable) operating 100% decentralized on low-cost consumer hardware with very little energy consumption. You will soon be able to run a Cloakcoin node on a Raspberry Pi at home - silent and low priced. Our wallets are easy to install and easy to run!
How does it work?We use proof of stake (PoS) for consensus, which means existing coins held by users are used to help secure the Cloak network. This negates the need for expensive mining hardware associated with proof of work (PoS) mining. Cloakcoin requires no master nodes, custom blockchain formats or sub-blockchains. Cloakcoin wallets connect to each other and CLOAKSHIELD enables them to establish a private onion routing network like TOR (minimum 3 hops) and on this private network the wallets find participants to create and send ENIGMA transactions. ENIGMA produces transactions that are 'Cloaked' by other wallets. This means that as well as ENIGMA senders adding their funds to the ENIGMA transaction, Cloakers also provide matching amounts, which they receive back alongside a reward for helping to Cloak the send. This means that anyone examining the transaction cannot determine who is sending and who is receiving funds.
Here a sample ENIGMA transaction:

One of these people is the sender, one of them is the recipient. All others are “Cloakers”. That is what ENIGMA will do for you: nobody can tell who put in which 10 USD note or took it out.
Cloakshield provides a private Cloakcoin network for the exchange of encrypted messages between all Enigma nodes. It uses ECDH/RSA encryption to protect all communication required by Enigma. And, to use our previous money pot scenario, this is what Cloakshield does to cover your tracks:
You don’t throw the 10 USD into the pot yourself. You announce that you want to put 10 USD into the pot. You will receive a “secret list” of codes pointing to unknown recipients. You put the 10 USD into an envelope and stick one of the codes on it. This envelope is put into another envelope and the next code is used as address. You can repeat this up to 25 times. You hand the envelope over to the first person next to you. If the address code corresponds with his ID he opens the envelope, takes out the next envelope and passes it on. This will be repeated until the last envelope reaches its recipient. He opens it and finds the 10 USD which he throws into the pot.
If you keep your Cloakcoin wallet with your coins in it online you will earn an interest of 6% p.a. with PoS minting. If you participate as “Cloaker” for Enigma transaction you can earn a share of transaction fees.
As active ENIGMA node you will have the added bonus of getting your coins swapped during the ENIGMA process again and again.
