Deposit blocks are not signed before being included in the list of blocks.

[ggs134]

In child_chain.py,

If a block in is signed, then this block is appended to variable.

It is block signing process.

However, when deposit tx and make a block, this block does not signed but included in variables.

I think signing process should be implemented at child_chain.py, apply_deposit() function.

And merkle, too.

Deposit blocks are signed by depositor and their correctness is guaranteed by Ethereum. Signature of operator does not add anything of value.

Closing as operator does not need to sign deposit blocks
