Hashing of blocks is not working

Hi,

Nice project. Was working on a Go Blockchain implementation myself and noticed that your hashing always returns the same hash, throughout the entire chain.

The thing is that you are trying to hash a block with binary.Write(&buf, binary.BigEndian, block) which gives you an error you don't handle. The data for binary.Write must be a fixed-size value, your Block contains a string which isn't fixed size.

I've made a workaround by marshalling the block first, that way the binary.Write succeeds and your hashing the chain properly. It is a bit slow though, if you'll find a better solution, drop me a line.

You can see it here, feel free to use it:

Cheers.

HTTP is slow, switch to rpc

Switch form HTTP too RPC to increase the performance of every request and you get a lot of additional features which HTTP don't have.

This project seems pretty interesting. I can offer you my help to speed up the development process.

contact me anytime ;)

Missing previous hash

Looks like you're not supplying the previous hash when mining?

gochain/handler.go

Line 100 in fc3aa97

block := h.blockchain.NewBlock(proof, "")

Awesome work - this is a really useful resource!
