An entrepreneur working with bitcoins and an enthusiastic biohacker found an interesting place to store electronic currency - under his skin. Martin Wiesmeyer, known as Mr. Bitcoin, implanted two NFC chips in his hands at a conference organized by Permanent Beta .
Speaking with CoinDesk representative Wismayer, he said that he had already tried to store litecoin, darkcoin, dogecoin and bitcoin on small devices with a capacity of 888 bytes each. “As long as you can export your private key, you can record it in your own hands,” he added. Although the checks were successful, Wismayer is not going to use them long enough to store its cryptocurrency. As he said, this is because media coverage of this process compromised their safety.
Nevertheless, he said that the chips are a reliable and secretive storage system for those who are “embarrassed” about video surveillance. “If you do not advertise the implant, no one will know about it. Chips are not visible with full body scans at airports. Secret Agent Technology Available to All Users. ”
Having stumbled upon Bitcoin in November 2010, Weismeier was very keen on the idea of block chains. “It made the same impression on me as WWW in the early 90's.” Four years later, the Dutchman switched from mining bitcoins on an old laptop and fussing with the API to participating in the international ATM collective project , which installs bitcoin ATMs around the world.
Keeping currency in the body is another experiment, albeit an extreme one. The DangerousThings store, which sells $ 99 injection kits , warns that they have not been approved for public use. Wismayer says that after about a day the pain disappears and then you can begin to test the chip.
The implant is a small 2x12 mm glass capsule containing an RFID tag, which is usually used to label pets or products. The label does not tear away and does not require power. It receives energy and data from smartphones, tablets, etc. through the NFC antenna. “No charging required, no batteries needed. The device can withstand 100,000 records, so in principle it should be enough for a lifetime, ”Wismayer said.
Storage of cryptocurrency on the device is almost a painless process, not counting the installation. First you need to disable write protection. Then, using an application like NXP Tagwriter, you write your private keys to the device as text tags, one key per line. 888 bytes can store 888 characters. Total device can store up to 26 differentmini-keys of 33 characters . If someone does not need so many keys, you can use BIP-38 encryption , in which the key length is 58 characters. Although wear does not occur when reading, data will be stored for about ten years. Because of this, users will need to rewrite, update their tags approximately every ten years in order to avoid loss of information.
The functionality of implants is so far limited by their volume. However, in the near future this volume will be able to grow. “I met with Amal Graafstroy, the engineer who developed this implant, and he is working on new models that will contain more information - however, they will be larger in size, and you may have to somehow unfold them under the skin after installation.”
In this area, specialists are few. However, Wismayer believes that there are already about 3,000 people with such implants in the world. In fact, the injection kit collected 383%from the original goal of $ 8,000 at Indiegogo last December. And implants are constantly coming up with new uses. For example, Wismayer wants to check his tags on a wireless door lock, and try to use them as an alarm switch.
“I use these tags in real situations, my phones and tablets have been compatible with them (Android only, sorry, iOS lovers) for two years now. “I feel that by supporting these bio-hacking developments, we can find out what works and what doesn't.”
