Tinychain: a pocket-sized implementation of Bitcoin
I'm working on my own blockchain (not specifically bitcoin) implementation just to wrap my head around everything. One thing I'm not getting that also wasn't answered by the source code is how you check timestamps.<p>I understand the whole network time = median offset + local time thing, however I'm a bit fuzzy on how you check timestamps on previous blocks when you're initially downloading the chain. How do you know that you need to check the timestamp if you can't know if you're on the latest block?
