Two Ethereum Improvement Proposals (EIPs) have been approved to be implemented in Ethereum's next major upgrade - "Istanbul".

The two Ethereum improvement proposals officially approved this time are tentatively scheduled to be activated on the Ethereum mainnet in October this year. In fact, developers also discussed 30 proposals related to the "Istanbul" upgrade in the latest Ethereum conference call. Ethereum improvement proposals, including which proposals will be approved, which will be rejected, and which will be delayed for later system-wide hard fork upgrades.

EIP 2024 and EIP 1702

EIP 2024 (referred to as EIP 131 in some documents) adds a new precompilation in the Ethereum virtual machine. The cost of operating precompilation on the Ethereum blockchain is usually relatively expensive, and basically a A flat fee or "gas cost".

EIP 2024 introduces a precompilation of a new hash function called "Blake2," which is said to be faster than other traditional hash functions, such as SHA-3, in verifying and authorizing blockchain data. At present, some other cryptocurrency projects are already using "Blake2", such as the privacy cryptocurrency Zcash and the domain name platform Handshake. This time, EIP 2024 introduces a brand new Blake2 precompiled version called "Blake2B".

James Hancock, one of the three authors behind the EIP 2024 Ethereum Improvement Proposal, explained:

"Introducing Blake2B means we can interoperate with Zcash on the Ethereum mainnet, such as 'wrapping' ZEC tokens near the Ethereum network, shielding transactions, or a lot of other cool things."

EIP 1702, written by Parity Technologies developer Wei Tang, is an ethereum improvement proposal aimed at smoother smart contract upgrades.

Currently, decentralized applications (dapps) running on the Ethereum blockchain are based on immutable, self-executing code — known as smart contracts. These smart contracts are compiled and executed by the Ethereum Virtual Machine, which is the core of the entire blockchain network and is deployed as an engine in thousands of decentralized applications created by developers.

The current Ethereum Virtual Machine is expected to be upgraded within WebAssembly code, which also provides developers with greater programming language and performance flexibility. EIP 1702 proposes to introduce a new hard fork method called "account versioning" to make it easier to upgrade the Ethereum virtual machine, or introduce new virtual machines to the network.
