Jack Dorsey’s blockchain watch brought Bitcoin to a House Committee hearing

CEOs of Facebook, Twitter, and Google spent much of Thursday answering questions from members of the House of Representatives Committee on Energy and Commerce. It was an important audience focused on the dissemination and impact of misinformation on social platforms. Still, it was hard not to be distracted at least a little by the background of the video chat that was Twitter boss Jack Dorsey’s kitchen. Amid the Twitter CEO’s piles of plates, bowls, and glasses was what appeared to be a strange little clock, with ever-changing numbers: 1952, 676274, 676277, 1935, 1922, 676289.

However, those are not esoteric expressions of time or date. They are last minute updates to the Bitcoin blockchain hosted on a dedicated “Bitcoin Data Screen”. It is manufactured by Coinkite, a Bitcoin security hardware manufacturer and is called Blockclock Mini.

Think of it as a ticker for the cryptocurrency blockchain. Blockclock connects to your local network and tracks a handful of stats: Bitcoin price, average fee rates, conversion rates, and more. Dorsey’s screen seemed to alternate between showing how many blocks currently exist on the Bitcoin blockchain, and how many Satoshis (the smallest unit of Bitcoin possible) does it take to add up to a dollar.

Speaking of which, at the time of writing, you would need 764,236 Satoshis to buy Blockclock. It sells for $ 400 on the Coinkite website.

I reached out to Dorsey to ask him more about his watch and his feelings on Bitcoin.
