Introduction

This is a guide to install libfive. libfive is a very unfinished program that allows you to model volumes. In other words, you can give libfive a functional representation of a solid, and libfive will figure everything else out, and render the resulting mesh. Pretty cool.

	02:26 CodeShark do what? SPV?
	02:27 petertodd CodeShark: yeah, they use getblocktemplate and what not to find
	when other pools make blocks, and quickly build on top of them - actually SPV is putting
	it strongly, they don't really do any authentication

	Your post advocates a

	( ) sidechains ( ) block-size increase ( ) anti-spam ( ) lightning-network ( ) off-chain

	approach to scaling Bitcoin. Your idea will not work. Here is why it won't work. (One or more of the following may apply to your particular idea, and it may have other flaws.)

	( ) There is no explanation of how Bitcoins on the sidechain will get back onto the mainchain.
	( ) This will make it more difficult to run a full node, when node counts are already dropping.
	( ) The idea of "spam transactions" is not well defined, and every proposed filtering method impedes legitimate use cases.
	( ) Your approach allows unrelated nodes to defraud each other, and there is no arbitration process other than "complain on reddit."
