Half of the nodes are out of sync
After the upgrade is completed, there will be no major fluctuations in the price of Ethereum. According to OKEx data, ETH is currently trading at $147, a 24-hour drop of 1.33%.
After completing the Istanbul upgrade, Ethereum founder Vitalik tweeted, congratulations to Sparkpool for digging out the Ethereum Istanbul upgrade block.
(Odaily Note: Currently Sparkpool mining pool ranks first with 34.44% of computing power.)https://blog.ethereum.org/2019/11/20/ethereum-istanbul-upgrade-announcement/。
Fortunately, the number of unsynchronized nodes is gradually decreasing, accounting for 50% at 8 am; as of press time, the proportion has dropped to 40.1%.

In addition, although this upgrade is a hard fork upgrade, no new coins will be generated. Investors are reminded not to be deceived, and there is no need to operate.

Weak sense of presence
The Istanbul hard fork upgrade is also the second upgrade of Ethereum this year.
"Just like the last major version update of EOS, (the Istanbul upgrade) is so calm that no one really cares about it." HelloEOS founder Zi Cen commented.
according toEthereum FoundationWhy is the presence of this upgrade so weak? An important reason is that this upgrade focuses more on protocol improvement and technology development. The upgrade content has a greater impact on developers, but the perception of the user end is not strong.according toEthereum Foundation
According to the official blog, this upgrade includes
6 EIPs (Ethereum Upgrade Proposal)
, which are:
EIP-152: Add Blake2 precompiled functions;
EIP-1108: Reduce alt_bn128 precompiled Gas cost;
EIP-1344: Add ChainID opcode;
EIP-1884: Redefine trie-size based opcodes;EIP-2028: Reduce Calldata Gas fees;）
EIP-2200: Redefining the net value of SSTORE Gas fees considering the change of SLOAD Gas fees.

"Interpretation of Ethereum Istanbul Upgrade Content"
In addition, one of the high-profile highlights of the Constantinople upgrade at the beginning of the year was the postponement of the difficulty bomb. However, there is no such plan for the Istanbul upgrade this time, which also reduces its attention.
The difficulty bomb will eventually turn into exponential growth. It is expected that the block time will reach 30 seconds in May next year, and it may be close to 1 minute next fall.
Fortunately, developers in the Ethereum community have also noticed this problem and have taken corresponding countermeasures.
At a recent developer meeting, developers agreed to an emergency hard fork to remove the difficulty bomb, weeks after the Istanbul upgrade. The proposal code is EIP 2384, and it is proposed to perform a hard fork at a block height of around 9.2 million to remove the difficulty bomb, which is expected to occur around January 6, 2020.

also received attention
In fact, Istanbul also attracted much attention when it called for proposals in May this year.
In addition, ProgPow, which has attracted much attention, was included in the solicitation of proposals, but due to audit and funding issues, it was postponed to the Berlin hard fork.
according toGithub Furthermore, many people regard the Istanbul hard fork as the last upgrade before Ethereum 2.0. In fact, Ethereum 2.0 is not ready yet. The latest situation is that Ethereum 2.0 Phase 0 - Beacon Chain deployment will be carried out in the first quarter of 2020.
