Ethereum is the network that currently has a high level of credibility in the cryptocurrency, digital money and Blockchain technology market. The update was carried out from December 2 to 6, 2019. This update for the Ethereum network is called Istanbul, which will bring with it a series of changes considered very important for the network code, these changes they will derive in the hard fork for the Ethereum Blockchain and will not have compatibility with the previous versions of the protocol.

What changes will Istanbul specifically implement?

The announcement of these changes was made by Hudson Jameson, warning that the date could probably change. Seeing the changes that the new version of the network will present, and the one that has generated the greatest expectation, is the EIP 1884, which brings a significant increase in the costs of computing resources, with an impact on people and interested organizations. in developing applications on the Ethereum network, which would prevent the Blockchain chain from becoming congested due to possible attacks or spam content.

Another new aspect (which was highly anticipated by programmers) consists of the new options that will be incorporated into the code and with which the Ethereum Blockchain data could be authenticated and verified more securely and quickly. It was indicated that the change will be executed in block 9,069,000 and the node operators were called to update their equipment as soon as possible, preferably before December 1 and thus avoid any possible inconvenience.

And why Istanbul?

It is a code name given to the eighth update of the main network for Ethereum. Istanbul has been tested four times through testnets, namely Görli, Rinkeby, Kovan and Ropsten, before its next exit to the main network. Likewise, in September of this year 2019, during the tests in Ropsten, the update was advanced, which caused a fork in the network. In total, there are six improvements that the network will have in mind in this first phase of updating, which were described as EIP-152, in which the precompilation Blake2 F compression function was added; EIP-1108 to reduce precompilation gas costs alt_bn 128; EIP-1344 adding a ChainID operation code; EIP-1844 presenting price changes for trie-size-dependent operation codes; EIP-2028 with reduction of gas costs for calldata and EIP-2200 to balance the cost of Sstore gas.

What do the changes of the hard fork of Istanbul mean?

The Ethereum developer community has increased considerably in recent years, Istanbul is the biggest update so far in terms of 30 EIP (Ethereum Improvement Proposals) that have been proposed (in total there have been 8 updates), of that lot , only six, are considered to be ready to be applied in the first part of the hard fork of Istanbul. A second part is expected to take place in the first quarter of the year 2020, with 8 EIPs accepted so far.
