Announcing MyEtherWallet v3.24.00: Difficulty Bomb&Updating blockchain

Due to the complexity of the Bomb and the increased risk of hacking, we pushed a rather drastic update that implements a number of changes and improvements, including enhancement of efficiency and scalability of the blockchain, acceleration of transaction speed, and additional security in the form new formats private keys which will help protect users against hacking.
If you are using private key or UTC, then you need to go into the wallet and update manually, otherwise they risk being unprotected.

How do i update my Ethereum wallet?

1. Go to our website /]MyEtherWallet.com
2. Unlock your wallet using your Keystore File (UTC / JSON) or simply use your private key.
3. Click Unlock and wait for the update.

Please note that you need to manually update your wallet, failure to do so may result in funds being lost.

We are taking these measures to protect both you and our network from phishing and malicious attacks.

Thank you for your cooperation and understanding!
MyEtherWallet Security Team.

If you use other methods, then ignore this message.

Yeah I understand the block would become orphaned. But would the other nodes add it to their databases or reject it?

It would not be orphaned.  Work for old blocks is no longer sent.  Only work for the current block is sent.  So hashes for past blocks would be rejected.

That block will be simply orphaned.
To do a fork you need to make your own client with its specific rules, and distribute it to people who will use it.

It is just a stupid question. Imagine if I start mining over an old block which already has many subsequent blocks, find a new block and submit to the network. Will they accept it and create a nonsense fork?

I know it is the longest chain that really matters, but would the network accept my block, creating the new fork or simply reject it?

Only work for the current block is sent out.  If you submit a hash for a past block it will be rejected, probably as stale or not meeting current difficulty.
