Hi BitMan, Can check the original thread by jgarzik, before LEO constellations were cool: https://bitcointalk.org/index.php?topic=334701.0 This is fascinating challenge to tackle on, a strong degree in theoretical physics or equivalent can only be a good start imho. Best, Antoine OTS hash: f941581f7565cd2d3ef3f1a8e15701fddc81c5f0c98f1bd7dc2911e46340c837 Le dimanche 6 juillet 2025 à 16:36:19 UTC+1, BitMan a écrit : > Hello, > > This is my first message to the Bitcoin Development Mailing List. > > Straight to the point: you might be familiar with the Blockstream > Satellite system, which broadcasts the Bitcoin blockchain globally. > Blockstream uses ground stations that receive a version of the blockchain > from Blockstream's infrastructure.
