The Ethereum community can be present process a tough fork at block quantity 2463000, which can doubtless happen between 12:00 and 13:00 UTC on Tuesday, October 18, 2016. A countdown timer will be seen at https://fork.codetract.io/.
As a consumer, what do I have to do?
Obtain the most recent model of your Ethereum shopper:
What occurs if I don’t take part within the exhausting fork?
If you’re utilizing an Ethereum shopper that isn’t up to date for the upcoming exhausting fork, your shopper will sync to the pre-fork blockchain as soon as the fork happens. You can be caught on an incompatible chain following the previous guidelines and you’ll be unable to ship ether or function on the post-fork Ethereum community.
What’s a tough fork in Ethereum-land?
A tough fork is a change to the underlying Ethereum protocol, creating new guidelines to enhance the system. All Ethereum purchasers have to improve; in any other case they are going to be caught on an incompatible chain following the previous guidelines. The decentralized nature of blockchain programs makes a tough fork improve harder. Exhausting forks in a blockchain require cooperation and communication with the neighborhood, in addition to with the builders of the assorted Ethereum purchasers to ensure that the transition to go easily.
What occurs throughout a tough fork?
After consensus is reached on what adjustments ought to be included in a tough fork, adjustments to the protocol are written into the assorted Ethereum purchasers, reminiscent of geth, Parity, and ethereumJ. The protocol adjustments are activated at a particular block quantity. Any nodes that haven’t been upgraded to the brand new ruleset can be deserted on the previous chain the place the earlier guidelines live on.
Why do we want a tough fork?
Since September 18th (UTC), the Ethereum community has been underneath assault by an individual or group leading to giant delays earlier than transactions have been processed. The community is at present stuffed with pending transactions which is inflicting customers delays in processing their transactions. You possibly can consider this as a denial of service (DoS) assault on the Ethereum blockchain.
Each operation that an Ethereum contract performs on the community is given a worth or gasoline price. Utilizing the ADD operation is much less computationally costly than performing a posh operation reminiscent of hashing a quantity utilizing SHA256. The attacker carried out a DoS assault by repeatedly calling sure operation codes (opcodes) of their good contracts which might be computationally troublesome for purchasers to course of, however very low-cost so as to add to the community. With the intention to stop the attacker(s) from persevering with to flood the community with low-priced contracts with excessive computational price, we’re elevating the worth of sure operations.
Why are we doing two exhausting forks and what is going to the consequences be?
The 2 exhausting forks every tackle completely different issues which have arisen from the assaults. The primary exhausting fork is supposed to handle pressing community well being points regarding underpriced operation codes. As described in Ethereum Enchancment Proposal 150, “EIP 150 Exhausting Fork,” the primary exhausting fork is about to happen at block quantity 2463000 and can modify the worth of underpriced opcodes concerned within the assault. The second exhausting fork is anticipated to handle quite a lot of much less pressing issues reminiscent of eradicating empty accounts which the attacker used to flood the Ethereum community, and which prompted the scale of the blockchain to inflate. The second exhausting fork remains to be being mentioned.
After the second exhausting fork has been applied, there’ll doubtless be a “clean-up interval” throughout which period there could proceed to be delays and difficulties processing transactions and syncing till the blockchain state has been totally debloated.
How will the EIP 150 exhausting fork have an effect on contracts?

The place can I discover extra technical particulars on what the 2 new exhausting forks will change within the protocol?
The respective adjustments to Ethereum protocol are documented within the GitHub repository for Ethereum Enchancment Proposals
The next two EIPs describe the present plans for the upcoming exhausting forks:
An enormous because of the Ethereum neighborhood for his or her endurance and understanding, and to all Ethereum builders throughout all purchasers and platforms who got here collectively to supply enter, ideas, and contributions to handle stopping the assaults and serving to to enhance the platform.
