As the cost of many internet connectivity options throughout the world is often based on how much data is transferred, running a full Bitcoin node can be an expensive venture. Until now…

Blockstream Satellite eliminates these cost barriers and enables people to receive blocks at no cost allowing more people to utilize Bitcoin and participate in the Bitcoin network.

I.e, if bandwidth is expensive you are not incentivized to run a full node. In this way to sync your node via the satellites and pay for bandwidth when broadcasting transactions.

Also in case govts try to censor btc and cause partitions you can detect this via the data collected from the sats.
Blockstream Satellite provides an alternative method of receiving the blockchain that is not affected by connection failure. This protects against network interruptions and prevents any participating node from becoming isolated or partitioned.
