Quarz correspondents visited the secret repository of the bitcoin-company Xapo in the Swiss mountains.
The Xapo bunker is a former military bunker, dug in a granite mountain near the eastern side of the Lucerne Lake. It was built in 1947, and during the Cold War was used as the secret office of the Swiss army. Its precise location is secret, and access is limited by security measures
The founder of Xapo is the Argentinean entrepreneur Wences Casares, and it is said that thanks to him first bitcoins were acquired by Microsoft CEO Bill Gates and LinkedIn co-founder Reed Hoffman. The company does not disclose the number of bitcoins stored in the bunker, but it is known that the deposits of some customers are estimated at millions of dollars. A bitcoin vault doesn’t store actual bitcoin units. Technically, what’s being stored are private, cryptographic keys. Getting unauthorized access to such private keys is equal to robbery, and it is not surprising that the company takes the highest security measures. The bunker itself is guarded by the company called Deltalis, which has a data center of about a thousand square meters. Server racks for storing keys are located at a depth of 320 meters inside the granite mountain.
The entrance to the bunker is a concrete façade. Inside there is a waiting room, where each visitor is carefully checked - whether he is recorded for a tour, as well as his personality. Visitors in the reception are photographed and a biometric pass is being issued. After that, the visitor enters a narrow cylinder of bullet-proof glass, the size of a telephone booth in which it is closed, until the operator opens the door from the opposite side. The data center itself is small. There is a cooler and one more door. What is behind this door is inaccessible to anyone except the employees of Xapo. It's already forbidden to take pictures there.
Is it not too much of security? “We are under attack 24/7,” said Carlos Rinzi - the head of Xapo security, referring to the terrorists and hackers he designed the vault to guard against. “This is not a race. It is a chess game. You have to think about the opponent’s next movement. You can never relax.”
