at this point, every time the longest chain "wins" if the hashes are valid.. but they could be what they want to be as long as the genesis block is the same.

as an example:
Node 1: first node, no others peers given

Node 2: only the first peer is given, connects to this one via websocket connection

Node 3: knows both Nodes and connects

Node 4: knows only Node 1 and connects to this one

if Node 4 mines a block, it only sync's the chain with Node 1 and not with 2 and 3.
Node 1 will also not sync the chain with 2 and 3 cause only in case of mining a new block

the account who wants to send an higher amount than their wallet contains, get an error message.
However, the transaction is undefined, so the transactions array remains empty or contains undefined elements. So the connected sockets will crash if the sender broadcasts the "new" undefined transaction.

... cause of "cannot read property 'input' of undefined"
