Actually, we had some pretty interesting ideas regarding the blockchain but we mostly agreed that we need to improve the wallet in areas that really affect the user experience. I don't find the sheer size problematic, but would like that we concentrate on shortening the initial load time. And usually the simplest ideas are the best. So I would like to see some sort of optimized blockchain P2P preloader that would make the initial download in under 2 minutes. What do you think?
After some research I'm finding that holographic hard drives are just around the corner so block chain size might not matter so much at least in the short term. So there's time. Basically the idea I was thinking about was making the block chain holographic but if hard drives are holographic then it would be way easier ; )
