So when are we going to see dedicated Bitcoin hardware? Most of the security problems with Bitcoin arise from using the software on general purpose computers, which don't mind if arbitrary processes examine the memory of the Bitcoin client. Trusted Platform Modules and smartcard chips, on the other hand, can encrypt incoming data without leaking the private key. You'd only need a couple thousand more gates (WAG) to run Bitcoin on secure silicon.
In fact, this is such a patently obvious insight that someone else must have thought of it already.
- wmf 15y agoThere have been discussions on the forum, but nothing serious. (There's specialized Bitcoin mining hardware, but we're talking about wallet storage here.) I don't think a smartcard is really enough; you need something like the IBM ZTIC, and it's not clear that people are willing to pay for that. There was some discussion about using trusted computing: https://bitcointalk.org/index.php?topic=67508.0 https://bitcointalk.org/index.php?topic=67508.0
- rmc 15y agoMost security problems with BitCoin are from bitcoin exchanges who don't know about security.
- DanBC 15y agoDifferent, but this guy has made physical bitcoin coins. It seems like a clunky expensive way to use bitcoins. I'm not sure if they're legal in the US. (https://www.casascius.com/ https://www.casascius.com/)
