This is very interesting check the link above.
Web sites and applications shouldn’t have to rely on problematic identification methods such as usernames and passwords.
- This is a human problem.
- This is a customer support problem.
- This is an industry problem.
Using 1Block for authentication purposes has many benefits.
- supported by nearly all smart phones and browsers
- simple registration and login process for end user
- eliminates keyboard interaction
- reduces phishing/malware risks
- reduces need for 2nd factor auth
- no need to remember, create or change passwords
- services know only site-specific public addresses
- no personal or sensitive information supplied with a login
- each login is unique, no useful information to sniff
Classical password authentication is an insecure process that could be solved with public key cryptography. The problem, however, is that it theoretically offloads a lot of complexity and responsibility on the user. Managing private keys securely is complex. However this complexity is already being addressed in the Blockchain ecosystem. 1Block leverages these efforts and makes authentication a much simpler and safer process for the end user.
Your ID is never exposed outside of your device, and it is stored encrypted. There are no trusted third parties required (ie. DropBox.) Because of this secure design, changing passwords becomes a thing of the past. In the unfortunate event your ID is compromised, ID revoking and replacing is an easy and built-in feature.
1Block boils this technology down to an easy user experience, and also easy and flexible server implementations. 1Block can replace traditional password logins, or act as a secondary factor of authentication, or used for any implementation where secure proof of ownership is required. 1Block is free to use and open-source.

If you’re a bitcoin nerd, you’ll know that finding cheap, low-power mining hardware is pretty hard to do. USB “thumb drive” miners are traditionally woefully underpowered – the little mining rig under my desk right now is running three three BlockErupters and I’m essentially paying for the pleasure of mining bitcoin – but this 11GH/s unit seems to have what it takes to at least make a dent in the blockchain.
Confused as to what this does? Read my tutorial for a bit of context. Essentially this board runs the calculations that makes bitcoin work and, more importantly, runs them fast enough to earn you a little money.
It’s sold by ASICRunner and is in stock right now. At a little over $265, it’s affordable to the average miner and it can run on a standard USB hub and host machine, which seems to include the Raspberry Pi. It uses last year’s Bitfury chips, special ASIC designed for mining, on a “stick” board with a single USB jack. This means you can place a bunch of these on a hub and because they aren’t as power-hungry as a traditional ASIC you don’t have to worry about them overheating.
Will you make much money with this rig? Probably not. It’s essentially baby’s first bitcoin miner and you’ll max out at about $15 a month until the difficulty goes up too far for this device to even be effective. However it’s an exciting change in the mining landscape and well worth considering if you want to attach a few of these together and try to make your money back that way.
