Title: [BitShares] All you need to know about Privacy in BitShares/DPOS (Project: TITAN Post by: merockstar on June 24, 2014, 11:06:53 AM https://github.com/BitShares/bitshares_toolkit/wiki/AYNTK_TITAN
All about TITAN Where is the name TITAN coming from? TITAN stands for T ransfer I nvisibly T o A ny N ame and describes that transactions performed are anonymous by default. How can I use it? Just type: wallet_transfer AMOUNT UNIT sender receiver memo The wallet will do the rest! As you can see it's the basic transmit procedure, thus all transactions are anonymous on the blockchain by default! What does it mean? What are the features? No need to exchange ugly addresses. Instead a Name can be registered with the blockchain which suffices to receive payments The receiver is anonymous to everyone except the sender. Simplifies accounting in the wallet, as you can register arbitrary names and no one can see your balance (except you, of course)! How can the receiver be anonymous for everyone else? For each payment a temporary one-time address is generated The details of TITAN can be summarized to: dan => DANS_EXT_PUBLIC_KEY scott => SCOTTS_EXT_PUBLIC_KEY scott: Generate OneTimePrivateKey & OneTimePublicKey Pair scott: OneTimePrivateKey * DANS_EXT_PUBLIC_KEY => SECRET DANS_EXT_PUBLIC_KEY.child( SECRET ) => RECEIVE_PUBLIC_KEY => RECEIVE_ADDRESS scott: RECEIVE_PUBLIC_KEY * SCOTTS_EXT_PRIVATE_KEY => CHECK_SECRET => SHORT_HASH(CHECK_SECRET) == SHORT_SIGNATURE scott-broadcast: OneTimePublicKey + RECEIVE_ADDRESS + ENCRYPT( from scott + SHORT_SIGNATURE, SECRET ) dan: OneTimePublicKey * DANS_EXT_PRIVATE_KEY => SECRET DANS_EXT_PRIVATE_KEY.child( SECRET ) => RECEIVE_PRIVATE_KEY => => RECEIVE_PUBLIC_KEY => RECEIVE_ADDRESS dan: DECRYPT( data, SECRET ) => "from scott" + SHORT_SIGNATURE dan: SCOTT_EXT_PUBLIC_KEY * RECEIVE_PRIVATE_KEY => CHECK_SECRET => SHORT_HASH(CHECK_SECRET) Isn't that exactly the same as bitcoin's stealth-addresses? This is a variation of stealth addresses (http://www.coindesk.com/stealth-addresses-secret-bitcoin-privacy) that leverages the name system to solve the first part of the problem. Just type: wallet_transfer AMOUNT UNIT sender receiver memo Are read-only/watch-only keys possible with TITAN? Yes. The basic support is already in place. Where can I find more about about the various types keys used in TITAN We have a dedicated article about the key structures in place in this wiki: Wallets, accounts, owners & active keys - The differences between Bitcoin and Bitshares What advanced features does it have? Ability to encode a message and 'from' data into the transaction for payment details, much like a 'purpose field' Sources https://bitsharestalk.org/index.php?topic=4887.msg64091#msg64091 https://bitsharestalk.org/index.php?topic=4699.0 Title: Re: [BitShares] All you need to know about Privacy in BitShares/DPOS (Project: TITAN Post by: xeroc on June 24, 2014, 11:21:33 AM On the current testnet TITAN works flawlessly .. it's incredible ... instead of..

so are there transaction hashes so i can prove i sent the money/btsx. if dan buys something from stans shop and then stan says he did not receive the money how can you verify stan received it without blockchain transaction hashes?
