Hansa Locktime files

Has anyone tried to finalize any locked transactions from Hansa? Its now past the 90 day wait for some of my transactions but when i try to broadcast the signed transaction using coinb.in i get an error stating "missing inputs".

Anyone else have any experience with this?

Police spreading Excel files laced with phone-home beacons The second method of operation spotted by the Dark Web community involves so-called "locktime" files that were downloaded from the Hansa Market before Dutch authorities shut it down on July 20.

Under normal circumstances a locktime file is a simple log of a vendor's market transaction, containing details about the sold product, the buyer, the time of the sale, the price, and Hansa's signature. The files are used as authentication by vendors to request the release of Bitcoin funds after a sale's conclusion, or if the market was down due to technical reasons.

According to people familiar with Hansa's inner workings who shared their knowledge with Bleeping Computer, Hansa locktime files were usually just a simple text file.

Before the market went down, these locktime files were replaced with Excel files that contained a hidden image. When the vendor opened the file to view transaction details, the image would load on the vendor's computer.

This image was hosted on the Hansa Market, and once loaded, the server would log the user's IP address. If the user didn't use a VPN, proxy, or funneled all OS-level traffic through Tor, the Hansa server would log his real IP address.

Even if the Hansa Market went down, some vendors might still have the files laying around their computers. After Hansa went down, vendors most certainly opened the files looking into ways to retrieve any funds still locked in Hansa's accounts.

Well like /u/basjin mentioned, from like July 18-20 or something like that they were serving up an xlsx version of the locktime with the clever little homing beacon.

If you have the locktime txt file from before that, you should be able to sign the transaction with your private key and broadcast it.

Un/Fortunately, I personally do not have any knowledge of how Hansa did things (never even visited the site) - so what exactly do you have OP?

ie, did they give you a redeemscript?

Or just the locktime txt containing the tx id's?

The redeem script was bullshit anyway on buyer's side too. Had a wallet address for multi tx that never got coin sent to it-instead funneled to LE's pocket.

Based on my understanding of the protocol:

If you did a 2-of-3 transaction, you and the vendor should be able to release it. You simply need to sign the appropriate transaction with your private keys. You shouldn't need anything other that your keys and the input and output addresses. You can build the transaction yourself using open source tools.

If you did a 2-of-2 transaction, you cannot sign the transaction. However, Hansa should have provided a pre-signed transaction to the vendor that would become valid after a 90 day period. Unfortunately, since the police had control of the market, it seems they were providing fake transactions that do not work. So 2-of-2 funds spent after the market takeover may not be recoverable.
