Do I have to trust the seller with the private key? If I want to keep this long-term, can I ever trust the 25 bitcoin stays in there?
Yes. Same principle of trusting Mike C, smoothie, etc.
Maybe Bobby should explain the manufacturing process, with regards to security, like Mike did years ago.
Hi all,
Yes, I'm happy to explain this.
The manufacturing process for the Bitcoin Block is somewhat different than for the other BTCC Mint coins.
The reason is how the final product looks like, where the Block number, the BTC amount are laser etched onto the nugget.
(We call it the bitcoin nugget!)
First of all, I've set aside and created a bunch of dedicated private/bitcoin addresses to make these nuggets. The private key creation is all done on an offline computer, and the files are never sent electronically over the wires, nor do they ever touch an online computer at all. The private keys are all stored securely on a spinning HDD. The drive is encrypted, and the file is held inside an encrypted volume on the drive. The hard drive is always kept in a safe, only accessible by me, and not touched by any other members of the company. The drive will be erased, wiped, and physically destroyed once the printing of keys have been done after this batch of the 25 BTC nuggets. For reasons obvious to all members of this forum, the handling of the hard drive and electronic file containing the private keys is a very sensitive affair. I am fully aware of the dangers and security risks associated with this, and I have taken all these steps to ensure the safety of these funds, and the reputation of BTCC.
The corresponding public address have been used to make the hologram stickers, where the address is printed onto the sticker, just like the other BTCC Mint coins. However, this is a different, second generation sticker, specific for the N Series, and has a few more anti-counterfeiting features, such as micro printing and some 3D effects of our logo.
Here is the assembly sequence:
1) We mine the block into the address. We check and double check, to make sure the addresses, block height, and amounts are recorded correctly.
2) We then laser etch the information of the mining details onto the top side of the physical block, including the corresponding QR code of the bitcoin address. Optionally, we would laser etch the Forever message on the backside of the block, if that was custom ordered.
3) After the block is made, we check again, to ensure the bitcoin address, block number, and BTC amounts all match.
4) Then, in a private setting, I would personally print the private codes, machine cut them into the small circles, and then attach to the block with the hologram sticker, one block at a time. (This whole step is done by me completely, with at most one senior company management team member helping, but never leaving them alone with the sensitive private ket material.)
5) Once the full block is made, it is wrapped and then sent for storage in a safe/vault, before being sold or shipped.
Please let me know if you guys have any other questions.
thanks,
Bobby
