All that means is that the experiment might reach the hard fork tipping point faster than mainnet would. Verifying that the network can handle such transitions, and how larger blocks affect the network, is the point of testing. > > And when I refer to testnet, I mean the public global testnet blockchain, not in-house isolated networks like testnet-in-a-box. I would expect any uncontroversial hardfork to be deployed in testnet3 before it is deployed in bitcoin's main chain. In any case, you can already do these tests using https://github.com/bitcoin/bitcoin/pull/6382 Note that even if the new testchains are regtest-like (ie cheap proof of work) you don't need to test them "in-a-box": you can run them from many different places. Rusty's test ( http://rusty.ozlabs.org/?p=509 ) could have been perfectly made using #6382, it just didn't existed at the time.
