The Blockstream Satellite API is currently in Beta and is utilizing Lightning Testnet method for payment. The Blockstream RESTful Satellite API responds with a JSON object and allows you to submit messages for broadcast, that support broadcasting secure messaging, alternative blockchains, a global podcast and more. It provides a way to create applications that broadcast messages globally using the Blockstream Satellite network. It is open for anyone to integrate the API into existing applications or build new services that can send both encrypted and unencrypted data. The Blockstream Satellite network broadcasts the Bitcoin blockchain for free. Blockstream aims to reduce reliance on trust, by providing global Bitcoin and blockchain technology for financial markets.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
