The Ethereum community might be present process a tough fork at block quantity 2463000, which can seemingly happen between 12:00 and 13:00 UTC on Tuesday, October 18, 2016. A countdown timer could be seen at https://fork.codetract.io/.
As a consumer, what do I must do?
Obtain the most recent model of your Ethereum shopper:
What occurs if I don’t take part within the onerous fork?
In case you are utilizing an Ethereum shopper that’s not up to date for the upcoming onerous 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 must improve; in any other case they are going to be caught on an incompatible chain following the previous guidelines. The decentralized nature of blockchain techniques 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 must 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 selected block quantity. Any nodes that haven’t been upgraded to the brand new ruleset might 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 below assault by an individual or group leading to giant delays earlier than transactions have been processed. The community is presently 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 value or fuel payment. Utilizing the ADD operation is much less computationally costly than performing a fancy operation reminiscent of hashing a quantity utilizing SHA256. The attacker carried out a DoS assault by repeatedly calling sure operation codes (opcodes) of their sensible contracts which can be computationally troublesome for purchasers to course of, however very low-cost so as to add to the community. With a view to forestall the attacker(s) from persevering with to flood the community with low-priced contracts with excessive computational value, we’re elevating the value of sure operations.
Why are we doing two onerous forks and what’s going to the results be?
The 2 onerous forks every deal with totally different issues which have arisen from the assaults. The primary onerous fork is supposed to deal with pressing community well being points regarding underpriced operation codes. As described in Ethereum Enchancment Proposal 150, “EIP 150 Exhausting Fork,” the primary onerous fork is about to happen at block quantity 2463000 and can regulate the value of underpriced opcodes concerned within the assault. The second onerous fork is anticipated to deal with quite a few much less pressing issues reminiscent of eradicating empty accounts which the attacker used to flood the Ethereum community, and which triggered the scale of the blockchain to inflate. The second onerous fork remains to be being mentioned.
After the second onerous fork has been carried out, there’ll seemingly be a “clean-up interval” throughout which period there might proceed to be delays and difficulties processing transactions and syncing till the blockchain state has been totally debloated.
How will the EIP 150 onerous fork have an effect on contracts?

The place can I discover extra technical particulars on what the 2 new onerous forks will change within the protocol?
The respective adjustments to Ethereum protocol are documented within the GitHub repository for Ethereum Improvement Proposals
The next two EIPs describe the present plans for the upcoming onerous forks:
A giant 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 deal with stopping the assaults and serving to to enhance the platform.
