We are rebuilding our hardware bitcoin wallets again.
Why? First, to document the build procedure in excruciating detail. Second, to try to break it and find additional problems. Third, to try to make the installation less hardware dependent and more portable – maybe to even run on any PC from a USB stick?
After we rebuild this time, we fully expect to find some more issues that need to be resolved, but we are close to actually trusting these things with real bitcoin.
