Ethereum [ETH] Upgrade to go live on Rinkeby Testnet on Wednesday Jan 9.


Ahead of a launch on the Ethereum mainnet, the planned ethereum hardfork will go live on Rinkeby Testnet on Wednesday Jan 9, an ethereum core developer have announced. In a tweet on Monday, Peter Szilagyi, a team lead at Ethereum called on operators to update their nodes ahead of the testnet hardfork

He wrote:

“Rinkeby #Ethereum testnet hardfork will land around 13:00 UTC on Wednesday, 9th of January! Last call to update your nodes. Also, please ensure you’re either running with `–rinkeby`, or that you `geth init`-ed your node with the updated genesis spec from”

Constantinople: The Journey to January 16.

This latest planned hardfork dubbed Constantinople has kept ethereum core developers and ethereum fans on the edge. Originally planned to launch on the Ethereum blockchain last year, the upgrade was delayed after it encountered problems on the Ropsten testnet—one of the three test networks used by ethereum developers. Others are Kovan and Rinkeby.

When the hardfork was implemented on Ropsten last October, it got stuck due to consensus problems. The release manager for the Ethereum client Parity Afri Schoedon wrote that it resulted in a three-way fork—that is between parity, geth and ropsten.  Ethereum core developer Lane Rettig confirmed this noting also that they noticed a consensus bug in the Parity implementation of Ethereum.

Constantinople is important because it implements certain Ethereum Improvement proposals (EIPs) which takes the blockchain closer to a Proof of Stake (PoS) consensus algorithm. Ethereum currently operates the Proof of Work (PoW) just like bitcoin which requires energy-intensive mining process.

The upgrade, just like others, will also reset the so-called “difficulty bomb” which makes it more difficult to mine ETH after a pre-programmed period. This was put in place to encourage frequent upgrading of the network.

As Smartereum reported, the hardfork has been set to go live on block #7080000, which according to current block times will coincide with January 16. Szilagyi, in a subsequent tweet reminded the ethereum community of the hardfork and the need to upgrade to client softwares that supports it.

He wrote:

“Ethereum mainnet Constantinople hardfork (16th of January) is fast approaching. Please make sure you are running Geth 1.8.20+ or Parity 2.1.10+/2.2.5+ to avoid unpleasant surprises!”

As Smartereum reported, Ethereum Client Software Geth in December announced a updated release of that supports the Constantinople Hard Fork. The new version, Geth 1.8.20 was described a special release and would also support the Rinkeby hardfork at block 3660663.
