The Ethereum community shall be present process a tough fork at block quantity 2463000, which is able to probably 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 person, what do I have to do?
Obtain the newest model of your Ethereum consumer:
What occurs if I don’t take part within the exhausting fork?
In case you are utilizing an Ethereum consumer that’s not up to date for the upcoming exhausting fork, your consumer will sync to the pre-fork blockchain as soon as the fork happens. You’ll be caught on an incompatible chain following the outdated guidelines and you’ll be unable to ship ether or function on the post-fork Ethereum community.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purchasers have to improve; in any other case they are going to be caught on an incompatible chain following the outdated guidelines. The decentralized nature of blockchain techniques makes a tough fork improve tougher. Laborious forks in a blockchain require cooperation and communication with the neighborhood, in addition to with the builders of the varied Ethereum purchasers to ensure that the transition to go easily.
What occurs throughout a tough fork?
After consensus is reached on what modifications ought to be included in a tough fork, modifications to the protocol are written into the varied Ethereum purchasers, similar to geth, Parity, and ethereumJ. The protocol modifications are activated at a particular block quantity. Any nodes that haven’t been upgraded to the brand new ruleset shall be deserted on the outdated chain the place the earlier guidelines live on.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 massive delays earlier than transactions had been processed. The community is presently stuffed with pending transactions which is inflicting customers delays in processing their transactions. You may 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 price. Utilizing the ADD operation is much less computationally costly than performing a fancy operation similar to hashing a quantity utilizing SHA256. The attacker carried out a DoS assault by repeatedly calling sure operation codes (opcodes) of their sensible contracts which might be computationally troublesome for purchasers to course of, however very low-cost so as to add to the community. In an effort to forestall the attacker(s) from persevering with to flood the community with low-priced contracts with excessive computational price, we’re elevating the value of sure operations.
Why are we doing two exhausting forks and what’s going to the results be?
The 2 exhausting forks every tackle totally 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 Laborious Fork,” the primary exhausting fork is ready to happen at block quantity 2463000 and can modify the value of underpriced opcodes concerned within the assault. The second exhausting fork is anticipated to handle a lot of much less pressing issues similar to eradicating empty accounts which the attacker used to flood the Ethereum community, and which triggered the scale of the blockchain to inflate. The second exhausting fork continues to be being mentioned.
After the second exhausting fork has been applied, there’ll probably be a “clean-up interval” throughout which era there might proceed to be delays and difficulties processing transactions and syncing till the blockchain state has been absolutely 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 modifications to Ethereum protocol are documented within the GitHub repository for Ethereum Improvement Proposals
The next two EIPs describe the present plans for the upcoming exhausting 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 offer enter, ideas, and contributions to handle stopping the assaults and serving to to enhance the platform.
