Previously, Ethereum Hard Fork Constantinople (also known as St. Petersburg) was scheduled for January 16, 2019, at block 7,080,000, which got postponed due to a vulnerability (allowing reentrancy) in Ethereum Improvement Proposal (EIP) 1283, which has been explained in a detailed way in the latter part of the article. So, at a core Ethereum devs meeting, it has been decided that Ethereum hard fork Constantinople finally happened on 28th February 2019, at approximately 19.30 UTC at block number 7,280,000. Ethereum 2.0, as its called, is a Proof of Stake (PoS) blockchain, that would allow quite a bit of a high number of Transactions Per Second (TPS) with low energy consumption. Ethereum remained quite stable and has not seen major fluctuations, as expected.

Ethereum has been showing a lot of volatility just before the hard fork is about to take place and this might impact the market like the time Byzantine fork took place and traders should be prepared accordingly. A few days back, Alex Krug, an economist stated that its typical of cryptocurrencies to crash before any fork events take place. This is how the ETH market volatility looks like:

This time, the hard fork would be released in two different parts, at the same time, wherein, in the first part, all the five EIP's would be there, and on the second release, EIP 1283 would be removed. This is basically what is going on with the Ethereum Constantinople Hard Fork. Ethereum Constantinople is getting closer so get ready to see some fluctuations towards the end of this month. After lots of analysis, the final date has been announced as Ethereum Constantinople postponement made the Ethereum enthusiasts low on energy.

Know Everything About The Ethereum Hard Fork

Ethereum couldn’t take its demotion over Ripple and recently, Ethereum gained back its second position and is working towards retaining the position forever or longer. On December 29th, 2018, Ethereum grabbed its old position, with a market capitalization of $15,293,262,380, and is valued at around $150 USD. Since the mid-Dec, Ethereum's market capitalization has doubled from around $8 billion to around $16 billion. The possible reason for the momentum in Ethereum price could be upcoming Eethereum Hard Forks.

What Led to the ETH Hard Forking?

Ethereum has decreased by more than 10x from its all-time high in 2018, and numerous platforms and companies, launched via Ethereum have been facing enforcement pressures from the US Securities and Exchange Commission for the trading of securities and unregistered issuance.

The developers have figured out that the difficulty bomb programmed into Ethereum has caused the blocks to become extremely slow after a point, after which no more blocks can be mined. The developers have to hard fork periodically so that ETH keeps on getting updated with the latest technology. Ethereum has already experienced a split once, which led to hard fork over the loss of the development fund and some didn’t agree on reversing any transactions even if it was a hack, which led to the formation of ETC (Ethereum Classic). The Constantinople hard fork will implement few major changes related to improve Ethereum blockchain performance and mining rewards mentioned in Ethereum Improvement Proposals (EIPs).

Out of all the active cryptocurrencies, February 2019 looks exciting for Ethereum as it is going to undergo the most awaited Constantinople hard fork. Let's get the details about the upcoming Ethereum hard fork.

 Ethereum Constantinople Hard Fork Explained

This is the major and the most significant ETH hard fork happening between before 14th to 18th January 2019. The Constantinople Ethereum hard fork, which is the 2nd phase of the Metropolis project, is expected to be built on 7080000 blocks, improving efficiency and performance. This is undertaken as a step to transit from Proof of Work (PoW) protocol to Proof of Stake (PoS) protocol (Casper update). This is expected to make the ETH network faster and less costly to operate. It might be controversial as it would decrease the miners' reward from 3 ETH to 2 ETH as well.

  • EIP 145: An upgrade which will efficiently detail and process the information processing on the ETH blockchain known as bitwise shifting. This will use 10 times lesser gas than before, which eventually would make the smart contracts cheaper to use.
  • EIP 1052: Optimising large scale code execution on the blockchain. Unique hash adoption would make the other contract verification easier as well as efficient.
  • EIP 1283: The pricing method will be made fairer and simpler in case of contract storage (SSTORE opcode). It would lower the gas cost as new uses would be enabled for data storage.
  • EIP 1014: Vitalik Buterin made scaling solution based on off-chain transactions and state channels similar to Bitcoin's Lightning Network, which will automatically improve the performance of the network.
  • EIP 1234: The reduction in block mining reward by 33% (also known as Thirdening) would delay the difficulty bomb for a period of 12 months. This would create ruckus amongst the miners as their block reward would decrease as happened earlier during the Ethereum Classic(ETC) hard fork. So, this difficulty bomb would make it impossible to mine after a certain point and would freeze the entire network, hence its also known as Ethereum's ice age. The developers would keep on improving and the miners have to adopt the update, else wouldn't be able to profit from mining.

As the developers are skeptical about the update and want to ensure the Casper update is safe, this got delayed a few times. Approximately around 5,500 blocks would be created every day, if every 15 seconds a new block keeps on getting created, which would definitely out pressure on Ethereum's value, and can prevent inflation.

The Constantinople hard fork is a part of infrastructure and protocol improvement for Ethereum blockchain, so we don't expect any new coins from this.

Possible Effects Of The Hard Fork On Ethereum

As the block rewards will be lowered to 2 ETH, investors must welcome a lower inflation rate of Ether supply. Anyway, miners have been struggling due to Ethereum price decline and slashing the block reward by one- third during this time could be seen as inconsiderate. Investors are in awe of what to expect from the upcoming Ethereum hard forks, especially after the last BCH hard fork happened in November 2018.

Some kind of short-term volatility is expected once the hard forks are announced. The transition into PoS is a risk, but Vitalik Buterin doesn’t mind taking that risk as he doesn’t care on the short-term impact on its price. What he actually cares is succeeding as an investment rather than a technology. As investors are aware of the transition’s benefits, more investors are going to get attracted.

Exchanges Supporting the Ethereum Hard Fork

What Must The ETH Hodlers do?

The price of Ethereum has surged 85% in the last 3 weeks and its market cap has doubled in last one month. The hard fork seems to be giving a boost to Ethereum price and its good news for hodlers.

After the Classic Vision Hard Fork, the owner gets 3 of ETCN for every ETH they have, after the ETH Nowa (ETN) Hard Fork, the ETH owners get 1 ETN for each ETH. The users will receive the new coins only if they have their ETH in a private wallet (Metamask, Ledger Nano S, Trezor, Myetherwallet, Imtoken, Guarda) where they control the private keys. 

If they have their ETH in exchange wallets then they will receive new coin if the exchange supports the respective hard forks. You can closely follow all the updates coming from the exchanges.

We also advise our users to do not import your wallet private keys to any new unrecognized wallets promising fee coins. 

Impact On The Crypto Ecosystem

The crypto space is awaited for one of the biggest and first forks of 2019. It would definitely have a huge impact on the ETH price, as it is happening to transform ETH into an updated version, which helps it to grow. We may expect that Ethereum price going high and the other cryptocurrencies might suffer a downfall for a short period of time during hard forks. Ethereum rose by around 85% over three weeks time.

We have seen similar happenings during or before Bitcoin Cash hard fork, wherein the other cryptocurrencies suffered for quite a bit of time. It is hard to predict the long-term impact of a hard fork and its evident that ETH is in a very critical phase now, as its going through a significant transition phase.
