Ethereum Istanbul upgrade announced | Ethereum Foundation Blog

The Ethereum network will undergo scheduled upgrades. Block number 9,069,000This is expected to occur in . Saturday, December 7, 2019. Exact dates may vary depending on different block times and time zones.

To account for variable block times, please upgrade your nodes before Sunday, December 1, 2019.

ethernodes.org They kindly provided Istanbul node statistics and a countdown timer. https://ethernodes.org/istanbul. etherscan.io We have provided a countdown timer in the following location: https://etherscan.io/block/countdown/9069000. Network upgrades can be monitored in real time. http://forkmon.ethdevops.io/.

What is Istanbul?

Istanbul is the name given to this network upgrade. Previous network upgrades were given different names: constantinople, fake dragonand Byzantium.

Is there anything I need to do as an Ethereum user or Ethereum holder?

If you use an exchange (Coinbase, Kraken, Binance, etc.), a web wallet service (Metamask, MyCrypto, MyEtherWallet, etc.), a mobile wallet service (Coinbase Wallet, Status.im, Trust Wallet, etc.), or a hardware wallet (e.g. Ledger, Trezor, etc.) If you use KeepKey, you don’t need to take any action unless you are instructed to do so by your exchange or wallet service.

What do I do as a node operator or miner?

Download the latest version of the Ethereum client.

Note: Harmony (ethereumJ) is now a deprecated client and does not support Istanbul. Besu is a mainnet compatible Ethereum client written in Java.

What happens if I’m a miner or node operator and don’t participate in the upgrade?

If you are using an Ethereum client that has not been updated to the latest version (listed above), your client will be in sync with the prefork blockchain when the upgrade occurs. Under the old rules, you will be stuck on an incompatible chain and will not be able to send Ether or operate on the Ethereum network after the upgrade.

What is Ethereum Land’s network upgrade?

Network upgrades are changes to the underlying Ethereum protocol to create new rules to improve the system. The decentralized nature of blockchain systems makes network upgrades more difficult. To ensure a smooth network upgrade of the blockchain, collaboration and communication are required with the community as well as various Ethereum client developers.

What happens during a network upgrade?

After the community reaches a consensus on what changes should be included in the upgrade, protocol changes are recorded in various Ethereum clients such as geth, Parity, and Nethermind. Protocol changes are activated at specific block numbers. Any nodes that are not upgraded to the new rule set will be discarded from the old chain where the old rules still exist.

What changes are happening in Istanbul?

Changes implemented in Istanbul are defined using the EIP. Ethereum Improvement Proposals (EIPs) describe standards for the Ethereum platform, including core protocol specifications, client APIs, and contract standards. Please refer to the EIP, which catalogs the specific changes that will apply to Istanbul. EIP-1679. Please also see This article by Ethereum Cat Herders It summarizes all changes and describes the extensive testing process.
