The Ethereum community will bear a tough fork at block quantity 2,675,000, prone to happen between 15:00 and 16:00 UTC on Tuesday, November 22, 2016. The countdown will be seen at https://fork.codetract.io/. The Morden testnet will bear a tough fork at block #1,885,000.
As a consumer, what ought to I do?
Obtain the newest model of your Ethereum consumer:
What occurs if I do not replace my consumer?
In case you are utilizing an Ethereum consumer that has not been up to date for the upcoming arduous fork, your consumer will sync with the pre-fork blockchain as soon as the fork happens. You can be caught on an incompatible chain following the previous guidelines and won’t be able to ship ether or work on the post-fork Ethereum community.
Importantly, in case your consumer is just not up to date, it additionally implies that any transactions you make will nonetheless be susceptible to replay assaults.
What if I exploit an internet or cell Ethereum pockets like MyEtherWallet or Jaxx?
Ethereum web sites and cell apps that permit you to retailer ether and/or make transactions run their very own Ethereum consumer infrastructure to facilitate their companies. Normally, you needn’t do something in the event you use a third-party web-based or cell Ethereum pockets. Nonetheless, it is best to nonetheless verify together with your net or cell Ethereum pockets supplier to see what actions they’re taking to replace for the arduous fork and if they’re asking their customers to take different steps.
Particularly, it is best to be sure that transactions are generated with the brand new replay-protected EIP 155 scheme.
What ought to I do if my Ethereum consumer has issues syncing with the blockchain?
Be sure to have downloaded the newest model of your Ethereum consumer.
Why do we recommend arduous fork networks?
“Spurious Dragon” is the second arduous fork of a two-round arduous fork in response to DoS assaults on the Ethereum community in September and October. Earlier arduous fork (aka “Tangerine Whistle”) resolved present community well being points attributable to assaults. The upcoming arduous fork addresses essential however much less pressing issues equivalent to additional adjusting opcode pricing to forestall future assaults on the community, enabling “debloat” of blockchain state, and including safety in opposition to replay assaults.
What modifications are a part of this tough fork?
Subsequent Ethereum Enchancment Proposals (EIPs) describe the protocol modifications applied on this arduous fork.
- EIP 155: Safety in opposition to replay assaults – prevents rebroadcasting of transactions from one Ethereum chain to an alternate chain. For instance: in the event you ship 150 take a look at ether to somebody on the Morden testnet, the identical transaction can’t be repeated on the primary Ethereum chain. Essential be aware: It’s EIP 155 backward suitable, so transactions generated with “pre-Spurious-Dragon” format will nonetheless be accepted. Nonetheless, to make sure that you’re protected in opposition to replay assaults, you’ll nonetheless want to make use of a pockets resolution that implements EIP 155. Observe that this backwards compatibility additionally implies that transactions created from various Ethereum-based blockchains that haven’t applied EIP 155 (equivalent to which is Ethereum Traditional) can nonetheless be performed on the primary Ethereum chain.
- EIP 160: EXP value enhance – adjusts the price of opcode `EXP’ to stability the price of `EXP’ with the computational complexity of the operation, basically making it tougher to decelerate the community by way of computationally costly contract operations.
- EIP 161: Stability clearing – allows the removing of a lot of empty accounts that have been put right into a state at a really low value because of earlier DoS assaults. With this EIP, ’empty’ accounts are faraway from the stability every time they’re ‘touched’ by one other transaction. Eradicating empty accounts vastly reduces the scale of the blockchain state, which is able to allow consumer optimizations equivalent to sooner sync instances. The precise removing course of will start after the fork by systematically performing a “CALL” on the empty accounts that have been created by the assaults.
- EIP 170: Contract code dimension restrict – modifications the utmost code dimension {that a} contract can have on the blockchain. This replace prevents an assault situation the place giant components of the account code will be repeatedly accessed with a hard and fast gasoline worth. The utmost dimension is about to 24576 bytes, which is bigger than any presently deployed contract.

This can be a extremely technical house within the making and creating. In the event you resolve to use the suggestions on this publish and proceed to take part, it is best to ensure you perceive the way it impacts you. You must perceive that there are dangers together with however not restricted to dangers equivalent to surprising errors. By selecting to implement these suggestions, you assume the dangers of the implications your self.
