> Batch openings don't seem to provide much scalability benefit I think they do. Suppose 10 people onboard to LN via Phoenix Wallet. Let's compare what it looks like with and without batching them. Without batching: 10 inputs, 10 signatures, and 20 outputs (the channel + change) With batching: 1 input, 1 signature, 11 outputs (10 channels + change) The latter is clearly much more efficient in terms of chain space and therefore much cheaper, and more scalable. The benefits accrue as the number of users onboarded in batches grows.
