Leo Wandesleb (Mycelium)“Segregated Witness is not a block size increase, but a technical necessity to fix completely different issues, by also producing less load on the blockchain,” Wandersleb explained. “There is, however, a realistic chance that it will take a long while before it has an effect on total transaction throughput.”
“I believe that Bitcoin Core, committed to these values, should acknowledge that increasing the block size or other hard forks might possibly be necessary. Nothing more
Thomas Voegtlin (Electrum)“It will be very easy to support transacting to Segregated Witness addresses,” Voegtlin explained. “But to really support Segregated Witness, we need to change address generation in the wallet, and the way transactions are signed. The first step will be to update the Electrum servers, in order to index Segregated Witness scripts – then to update the client. I can combine the server work with a more general update which I planned to do anyway. All in all, that will probably keep me busy for a few months
Aaron Voisine (Breadwallet) However, Segregated Witness will only give us something like an 80 percent capacity increase, and hard forks take a long time to deploy. The hard fork needs to be readied, and roll-out started quickly after. While I’d prefer it if Bitcoin Core does that, it appears Bitcoin Classic is the leading option for deploying a hard fork. As such, we do support that project.”
Andreas Schildbach (BitcoinJ, Bitcoin Wallet for Android)“When it comes to the block size topic, I think Segregated Witness is not a solution at all ... think that in practice, actual usage will grow slower with Segregated Witness compared to a 2-megabyte hard fork increase, as it requires all wallets and services to upgrade"
“Blocks are full, and I don’t agree that a hard fork solution would be short notice. We’ve been discussing this issue for years now! I would prefer we roll out a hard fork,” he said.
