We're opening up for European Union orders on an upcoming product within two weeks most likely so time to finalize how this concept will work:A customer will have to order either Verifikationsbrev: http://silkroadvb5piz3r.onion/silkroad/item/b5fe4b30f for Domestic use ( Sweden ) or Verification Letter: http://silkroadvb5piz3r.onion/silkroad/item/ff16ca31ee for European Union/International use. The username and Postal Code will be put on separate lines in a text file, hash checked by the application HashCalc. v2.02 and with the option HMAC enabled with a random password the checksum for RIPEMD160 will be the Unique Code. The Unique Code along with the password needed to replicate the Unique Code if the customer wants to do his own verification will be sent in a small envelope. We will on our end store the Unique Code, the password for the Unique Code and the 28 day validity which starts the time the Verification Letter is ordered - all encrypted of course and decrypting would only be necessary in the event of a dispute.This is kind of a middle ground solution, by basing the hash off the Silk Road username and the Postal Code itself the information would be off no use to Law Enforcement in the unlikely event they would somehow be able to crack it - the letter/text itself would not be proof of anything. The drawback is a buyer could hypothetically attempt to find an address with an identical Postal Code, send it to that new address and then claim the package didn't arrive and provide the Unique ID in the Resolution Center. In the unlikely event this happens I've decided that the Unique Code is only valid once per term, in other words it would be valid for one order during the 28 day period and if the buyer wants another Verification Letter for the same Postal Code he would have to wait until the old one expires alternatively get a new username or Postal Code.Some random notes the Unique Code will use the font "Consolas" so one can tell the difference between 0 and o and it will be converted into UPPERCASE. Not a single Domestic Order has been seized or had any trouble so far and no one has bothered to even ask about the concept, but it's bound to happen when sending abroad eventually. To quote the current terms:QuoteVerification Letter gives a bonus when having a dispute with us: http://silkroadvb5piz3r.onion/silkroad/item/ff16ca31eeThe first percentage rate is for ordinary customers while the second is for those in possession of a Verification Letter.With evidence of a seized order domestically we will repay you 75 % / 100 %, alternatively attempt to reship once.With evidence of a seized order internationally we will repay you 45 % / 75 %, alternatively attempt to reship once.For any order that hasn't arrived due to other reasons we will repay you 15 % / 50 %, excluding reshipments.I'll add here that with provided evidence of a seized order the reshipment doesn't have to be to the same address/postal code as it would obviously be burned for a while.A bonus might be to put some kind of material over the paper/text itself so it's evident if its been opened/tampered with, anyone have any suggestions on that aspect? :)
