Um, no.
First of all the limiter needs to be the decentralized internet p2p relay, since even a federation of satellite broadcasting companies is unacceptable. This is adversarial engineering where you design to operate in the worst case.
Second, it is validation of a block that matters, not mere receipt of the header. So how long it takes to transmit a block over the low bandwidth connection such a satellite provides, plus the time to validate CAN be significant as you increase the blocksize beyond the current 4MB.
- mrb 9y ago"First of all the limiter needs to be the decentralized internet p2p relay," The p2p overlay network should remain the backbone of Bitcoin. It is perfectly adequate for most nodes, however critics of large blocks have used the argument that a small percentage of nodes just don't even have adequate internet bandwidth. Now a satellite service gives them the guarantee they can receive blocks, no matter their size (bandwidth is sized appropriately), very cheaply, no matter where they are located in the world, no matter how bad their internet connection is. "Second, it is validation of a block that matters" I never said this satellite service will magically fix everything, just that it removes ONE hurdle of many.
