Is possible to send transactions with blockstream satellite? Noob question here. Is it possible to send bitcoin transactions using Blockstream Satellite node or is it used only for receiving blocks?
No, communication is unidirectional, you can only receive the data which is broadcast by the system. The satellites being used are TV relays, the uplink essentially being amplified and re-broadcast without any knowledge of the content.Transaction broadcast needs to happen by terrestrial services like a cellphone network, dialup modem, or just the regular internet.
