Hi BitMan,

Can check the original thread by jgarzik, before L= EO constellations were cool:

https://bitcointalk.org/index.php?t= opic=3D334701.0

This is fascinating challenge to tackle on, a st= rong degree in theoretical physics
or equivalent can only be a good st= art imho.

Best,
Antoine

Hello,

This is my first message to the Bitcoin Development Mailing List.

Straight to the point: you might be familiar with the Blockstream Satell= ite system, which broadcasts the Bitcoin blockchain globally. Blockstream u= ses ground stations that receive a version of the blockchain from Blockstre= am's infrastructure. Users can passively receive this data but cannot b= roadcast transactions or contribute updates to the blockchain being transmi= tted.

My concern is the lack of decentralization and the reliance on a single = company. I=E2=80=99m only 16 and still learning, but I=E2=80=99m passionate= about improving Bitcoin. I don=E2=80=99t fully understand how satellites w= ork yet =E2=80=94 but inspired by Elon Musk=E2=80=99s Starlink approach, I = believe it's worth exploring the idea of a fully open-source, community= -driven satellite communication system.

This system could allow users not only to receive but also to broadcast = transactions and synchronize blocks directly to and from full nodes in spac= e. That way, Bitcoin could truly function off-grid and without dependency o= n centralized ISPs or infrastructure. It would make Bitcoin more resilient,= censorship-resistant, and globally accessible.

Of course, such a project would be very expensive and technically comple= x. But perhaps it could be made possible through crowdfunding or support fr= om individuals passionate about decentralization and global freedom.

My dream is to see Bitcoin working almost offline =E2=80=94 pow= ered by minimal energy, generated through a small solar panel and paired wi= th a satellite dish. A full node that can send and receive data or even a s= ingular device exploring the blockchain or broadcasting a transaction, inde= pendent of centralized networks =E2=80=94 truly decentralized and powered b= y the people.

Thanks a lot for reading my message :)

Yours,
[Username not set yet :)]
