Everyone here is excited about the potential of Bitcoin and would aspirationally like it to reach its full potential as fast as possible. But the block-size is not a free variable, half those parameters you listed are in conflict with each other. We're trying to improve both decentralisation and throughput short-term while people work on algorithmic improvements mid-term. If you are interested you can take a look through the proposals: http://lists.linuxfoundation.org/pipermail/bitcoin-dev/2015-June/008603.htm= l Note that probably 99% of Bitcoin transactions already happen off-chain in exchanges, tipping services, hosted wallets etc. Maybe you're already using them, assuming you are a bitcoin user. They constitute an early stage layer 2, some of them even have on chain netting and scale faster than the block-chain. You can also read about layer 2, the lightning network paper and the duplex micropayment channel paper: http://lightning.network/lightning-network-paper-DRAFT-0.5.pdf http://www.tik.ee.ethz.ch/file/716b955c130e6c703fac336ea17b1670/duplex-micr= opayment-channels.pdf and read the development list and look at the code: http://lists.linuxfoundation.org/pipermail/lightning-dev/ https://github.com/ElementsProject/lightning Adam On 27 June 2015 at 16:39, Michael Naber wrote: > Demand to participate in a low-fee global consensus network will likely > continue to rise.
