<p>This is my first message to the Bitcoin Development Mailing List.</p>
<p>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.</p>
<p>My concern is the lack of decentralization and the reliance on a single =

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.</p>
<p>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.</p>
<p>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.</p>
<p>My dream is to see Bitcoin working <em>almost</em> 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=
