Leading provider of Blockchain technologies, Blockstream, has announced yesterday the launching of a satellite service to broadcast the Bitcoin blockchain.
Partially available today, Blockstream Satellite will allow anyone who wishes to maintain a complete node and monitor the blockchain anywhere in the world, regardless of internet access, with a low priced radio receiver, without any connection fees.
However, this free service does not allow you to send transactions to the network. Submitting a transaction is a resource-intensive operation that can be performed as soon as a mobile network is available, regardless of its quality, such as SMS.
On the other hand, maintaining a complete node and monitoring the blockchain (essential for all those who want to open two-way payment channels on the future Lightning Network), requires a stable connection and involves downloading more than 4 GB of data each month.
