The Ethereum community shall be present process a tough fork at block quantity 2,675,000, which is anticipated to happen between 15:00 and 16:00 UTC on Tuesday, 22 November 2016. A countdown timer might be seen right here https://fork.codetract.io/, The Trendy check community will endure a tough fork at block number one,885,000.

What do I must do, as a person?

Obtain the most recent model of your Ethereum consumer:


What if I do not replace my consumer?

If you’re utilizing an Ethereum consumer that has not been up to date for the upcoming exhausting fork, your consumer shall be out of sync with the pre-fork blockchain as quickly because the fork happens. You’ll be caught on an incompatible chain following the previous guidelines and you’ll be unable to ship Ether or work on the post-fork Ethereum community.

Importantly, in case your consumer is just not updated, it additionally signifies that any transaction you carry out shall be vulnerable to replay assaults.

What if I am utilizing an online or cell Ethereum pockets like MyEtherWallet or Jaxx?

Ethereum web sites and cell functions that let you retailer and/or transact Ether are working their very own Ethereum consumer infrastructure to facilitate their providers. Usually, you needn’t do something in case you use a 3rd occasion net primarily based or cell Ethereum pockets. Nevertheless, you need to nonetheless test along with your net or cell Ethereum pockets supplier to see what actions they’re taking to replace to the exhausting fork and whether or not they’re asking their customers to take different steps.

Specifically, you need to be sure that transactions are generated with the brand new replay-protected EIP 155 scheme.

What do I do if my Ethereum consumer is having issues syncing to the blockchain?

Be sure you have downloaded the most recent model of your Ethereum consumer.


Why are we proposing to exhausting fork the community?

“Spurious Dragon” is the second of a two-round exhausting fork in response to DoS assaults on the Ethereum community in September and October. rear exhausting fork (aka “tangerine whistle”) Resolved instant community well being points brought on by the assaults, The upcoming exhausting fork addresses essential however much less urgent issues resembling additional tuning opcode pricing to stop future assaults on the community, enabling “debloat” of blockchain state, and including replay assault safety.

What adjustments are a part of this difficult fork?

Following Ethereum Enchancment Proposal (EIP) Describe the protocol adjustments applied on this exhausting fork.

  • EIP 155: Safety towards replay assault – Prevents transactions from one Ethereum chain from being retransmitted on an alternate chain. For instance: in case you ship 150 check ether to somebody from the trendy testnet, the identical transaction can’t be replayed on the principle Ethereum chain. Vital Notes: EIP is 155 backwards appropriate, so transactions generated with the format “pre-spurious-dragon” will nonetheless be accepted. Nevertheless, to make sure that you’re shielded from replay assaults, you’ll nonetheless want to make use of a pockets answer that implements EIP 155. Remember the fact that this backwards compatibility additionally signifies that transactions created from various Ethereum-based blockchains that haven’t applied EIP 155 (resembling Ethereum Basic) can nonetheless be replayed on the principle Ethereum chain.
  • EIP 160: Improve in Exp Price – Adjusts the value of the `EXP` opcode in order that it balances the value of `EXP` with the computational complexity of the operation, primarily making it harder to decelerate the community via computationally costly contract operations .
  • EIP 161: Clearing State Makes an attempt – This makes it attainable to take away a lot of empty accounts that have been beforehand saved within the state on account of DoS assaults at little or no price. With this EIP, ’empty’ accounts are faraway from the state when ‘touched’ by one other transaction. The elimination of empty accounts drastically reduces the blockchain place dimension, which can present consumer optimizations resembling sooner sync instances. The precise takedown course of will start by systematically executing ‘calls’ on the empty accounts created by the assaults after the fork.
  • EIP 170: Contract Code Measurement Limits – Adjustments the utmost code dimension {that a} contract on the blockchain can have. This replace prevents an assault situation the place giant items of account code might be accessed repeatedly at a set fuel price. The utmost dimension is about to 24576 bytes, which is bigger than any contract at present deployed.
