The other solution to very strong anonymity is zerocoin/zerocash, which is still vaporware. It is promised for anoncoin, but as yet undelivered. It has a very real problem that some information required to seed the so-called Merkle tree needs to be destroyed. These systems therefore trust a "third party" (non-participant) to seed the Merkle tree and then destroy the information completely. The problem with zerocoin/zerocash, therefore is this aspect of trust.
The third solution is stealth addresses, which actually provide very good anonymity. A stealth address hides the recipient of a transaction completely. It does not hide the sender, though, so it leaks a lot of information about the transaction. But if you are missing every other dot in a transaction chain, it becomes very hard to connect them to make a clear picture. A huge advantage that stealth address transactions have over the other systems is that they require no more storage than a bitcoin transaction. So stealth addresses are a compromise, but in reality an excellent compromise. These work perfectly in SSD.
What do you think about Cloak coin solution POSA3? Coinjoining- No masternodes.. Good review would be very good, im not an expert so i'm very pleased with this post. I see you know alot about anonymity, please come here.
