The Hard Fork is Here!

in #crypto-news8 years ago

As you all know by now,the Ethereum community has elected to do a hard fork in order to resolve the DAO exploit. The MainNet block on which the hard fork will occur is set at 1920000, which should be reached on July 20 or 21 depending on your time zone.

In an email statement to clients last week about the hard fork we said:

ETH deposits and withdrawals will be disabled approximately 1 hour before the hard fork activates. Trading will continue as normal during the fork.

Some interpreted this statement to mean that we would not grant access to balances on the non-dominant chain under any circumstance but this was never our intention. The statement was written from the standpoint of a “winner take all” scenario where the non-dominant chain dies out fairly quickly. Since the outcome of the fork may be more complicated than this, we want to make a number clarifications here and assure everyone that we are making preparations to be ready for any outcome of the fork and will act accordingly.

How long will it take? Although the process may go smoothly and quickly, we want everyone to understand that we will be very cautious about waiting for a clearly dominant chain (with the most work on it) to emerge before enabling ETH and DAO funding again. Maybe this is unlikely, but depending on how things go, we may have to wait several days or more to be safe.

There are other ways to protect against the attack, but this guide has been at least partially endorsed by Ethereum co-creator Vitalik Buterin.

What about my private wallets? Please be very cautious with your private Ethereum wallets and do not send any transactions during the fork . Even after the fork you should be careful and understand the danger of the replay attack. If you only care about your funds on the dominant chain, then you do not need to worry about the replay attack.

But if you care about funds on both chains then you will need to take precautions against the replay attack. Unfortunately, aside from the highly technical guide linked above there isn’t a comprehensive guide for more ordinary users on how to protect yourself. But here is one place with some tips and discussion that is aimed at a somewhat less technical level:

Hopefully a better guide to navigating the fork with your private wallet will be available soon on https://blog.ethereum.org/ or elsewhere.

What about margin positions?
Margin traders who are uncomfortable with this possibility should close their positions prior to the start of the fork.

What about The DAO? Caution should be exercised for all Ethereum blockchain operations during the fork, including DAO and any other Ethereum based tokens.

Thanks and hope these infos are useful.

The words replay attack would send shudders through me if I was a DAO token holder...

hopefully you are an ETH holder,after the hard fork you might get rich :)
