I've created a private test net and can successfully connect to it from any machine. I can start mining there:
eth.sendTransaction() from one account to another too. I can see, that last transactions belong to 2000th block.
So here comes first question:
I propose, that all these blocks are stored in
geth/chaindata/*.ldb files, right? I want to be able to revert net state to a certain block(or transaction better), so all the nodes will accept this backup.
(I thought the first solution could be deleting certain
.ldb files on each node)
Second question: is kind of curiosity - what is being mined, when i do
miner.start() and do not generate transactions??
