Bitcoin Trx by Radio Wave

Bitcoin in the Air

This week, Rodolfo Novak revealed he had sent bitcoin via radio to another address over 350 miles away, without the aid of a satellite or any other sophisticated network. The OG cryptocurrency just got a little more permissionless.

After the initial bitcoin transaction, the small sum has been passed around to several other radio operators and is currently in the possession of podcaster Adam Curry.
As such, the bitcoin has traveled approximately 1700 miles in 24 hours, no internet involved.

Wait, What?
The technology these bitcoin enthusiasts are using is called shortwave radio, which uses a group of frequencies that bounce off the upper layers in the atmosphere to travel very long distances using relatively small amounts of power.

The technique can be traced back to amateur radio operators transmitting as far back as 1921 and can be done with a much simpler network infrastructure than is required for traditional bitcoin transactions.

This chain of transactions among shortwave operators in the U.S. represents a proof of concept for sending offline BTC in case of outages or network censorship (e.g. the possibly impending Russian internet blackout).
The current technique has limitations in that it requires a brain wallet and unencrypted communication (due to regulations and bandwidth limitations), but in an emergency it represents a powerful tool to move money where you otherwise wouldn’t be able to.

Why Should I Care?
Well, if you have bitcoin that you can’t use, what’s it worth?
The more tools developed to bootstrap the Bitcoin protocol on top of legacy or non-internet networks, the more options you have if, for example, a disaster destroys all of the cell towers and power substations in your area, or upnp/udp networking gets blocked by your ISP.
The more options you have to transmit your money the more valuable it is, so having established methodologies for sending bitcoin in as many ways as possible are essential to securing your wealth should a systemic threat damage the internet or people’s access to it.
What’s your take? Is this experiment a breakthrough for bitcoin users? Let us know in the comments section below.

Google Banned MetaMask.

Google has banned Ethereum (ETH) wallet and decentralized app (DApp) browser Metamask’s android client from its Play app store.

The MetaMask team took to Twitter on Dec. 26, where they announced that Google had suspended MetaMask’s android client from Google Play’s app store, claiming MetaMask was in violation of Google’s financial services policies.

Google reportedly cited their policy prohibiting cryptocurrency mining on mobile devices. The MetaMask team attempted to appeal Google’s decision to ban MetaMask from its app store to no avail, as Google promptly rejected the appeal. MetaMask co-lead developer Dan Findlay told Cointelegraph:

“I very much hope that this was an honest mistake on the part of Google's reviewers, but in combination with all the crypto YouTube bans, it definitely puts me at disease about how Google is engaging with decentralizing technologies. If people accept this behavior from a mobile monopoly like Google, we may not deserve something better.”

Not the only Google project to bar crypto-related content
Over the past several days, Google-owned video giant YouTube had removed videos from the accounts of several cryptocurrency-related content creators. Today, however, YouTube representatives have claimed that the removals were done in error and some content has started to be restored.

Nonetheless, the unilateral nature by which YouTube videos were removed and then reinstated has led many content creators to begin exploring migration to decentralized video hosting alternatives.
