Blockstream Satellite is the world’s first service that broadcasts real-time Bitcoin transactions and blocks from a group of satellites in space. It was introduced in 2017 and is still in operation today:
With the service, everyone will have free access to the Bitcoin network, in any corner of the world, including the estimated four billion people not currently connected to the Internet, due to lack of availability or affordability.
With coverage across the globe, the satellite allows for you to interact with the network without having a internet connection. This is important in areas where the internet can be shut off by totalitarian governments. Think of the restrictions recently imposed by India in the area known as Kashmir.
So I’m sorry dogecoiners, Bitcoin was the 1st cryptocurrency to leave orbit so therefore it is THE 1st spacecoin. It is the 1st blockchain to be broadcast from space.
