Please consider using multiple rounds of AES256 encryption for the wallet (bitcoin-qt style) until you meet a given time,
You mean multiple rounds of password hashing to generate the AES key http://en.wikipedia.org/wiki/PBKDF2Repeatedly doing AES does nothing, as AES is designed to be fast and it is implemented at hardware, like in Intel CPUs No, I actually thought of AES256-CBC: Wallet encryption uses AES-256-CBC to encrypt only the private keys that are held in a wallet. The keys are encrypted with a master key which is entirely random. This master key is then encrypted with AES-256-CBC with a key derived from the passphrase using SHA512 and OpenSSL's EVP_BytesToKey and a dynamic number of rounds determined by the speed of the machine which does the initial encryption (and is updated based on the speed of a computer which does a subsequent passphrase change). https://en.bitcoin.it/wiki/Wallet_encryption |

Even if you use Bitcoin through Tor, the way transactions are handled by the network makes anonymity difficult to achieve. Do not expect your transactions to be anonymous unless you really know what you're doing.

AES is encryption. It's not applied "repeatedly". The password is HASHED repeatedly (in this case with SHA512) PBKDF2 does exactly the same thing http://en.wikipedia.org/wiki/PBKDF2The encryption can still be AES with PBKDF2 So it works like this. User's password = password Hash the password, lets say 100,000 times to slow brute force. 100,000 times: password = Hash (password) .. Use the end result of that 100K hashes to encrypt with AES |

This is my investment , why not invest hosting my list Thank you Investment in escrow did not find me Thank you If you investment use escrow service, the best way is PM Anon136, so he can response you quickly. If you investment directly , its ok if you get confirmation from eXo_coin. Anyway , the best way for communication is PM the author directly. |

We should help the devs out by getting a logo competition rolling.
Is there any news on second round funding or time frames for the actual coin release?

U can see it at http://exocoin.org/index.php?s=whitepaperThanks +1 I'm glad they are opening second round funding after the open beta. Due to the risk of the first round investors, I hope they are rewarded appropriately. |

You are right we shoudl have updated the ETA time there as well. Here is the next version: whitepaper v1.2You can expect a major update on the whitepaper as of 1.3 1.2 "just" have some more/updated screenshots, small text rework but 2 diagrams for better understanding. And added some code snippets. V1.3 will contain security important code implementations (like the whole crypto implementations maybe). As stated - we will use the time from now on for code redesign, generating more debug information, fixing bugs and guard threads. Open beta *ETA* is 30th march (trying to get a working linux implementation until then as well (good chances we get it on-time), otherwise WINE will work at least.....) Website redesign and more "marketing things" will be faced in one or two weeks. +1. Making progress. |
