2/6 What is the EIP-4488?
EIP-4488’s full name is “Transaction calldata gas cost reduction with total calldata limit”. The main purpose of EIP-4488 is to reduce the cost of uploading off-chain data to on-chain to ~20% without introducing potential attacks on the network!

3/6 Why EIP-4488 is important to Ethereum
ETH is moving toward rollup centric, but one major cost of rollup is the upload cost of L2 data to ETH. With EIP-4488, the cost of such upload can be reduced to ⅕! See the latest post from
@VitalikButerin

@VitalikButerin
,QuarkChain is perhaps the ONLY blockchain project that has two official implementations - goqkc & pyqkc besides Ethereum (even BTC only has core in C++).

4/6 Why EIP-4488 is important to us?
Our
@Web3Q_io
project aims to provide a decentralized Web based on ETH tech. One key part is to upload rich Web content such as HTML/SVG on top of the blockchain. With EIP-4488, we can dramatically save the upload costs to just pennies!

1/2, I am working on EIP-5478 (CREATE3) which could dramatically reduce the gas cost of creating account abstraction contracts (e.g., EIP-4337) that have identical code.
The idea is to replace costly data storing gas with a cheaper contract lookup gas if the code is the same!

One argument I would make is that rather than each user creating the witness, under Ethereum PBS model, the builder should generate witnesses for all user txs which solves the problem.

To bridge the gap between traditional web users and the growing world of Web3, we propose a non-transferable, value-less gas token named SoulETH. The concept revolves around facilitating Web2 users' entry into Web3 by airdropping them with SoulETH. This…

Why we say multi-native token is important?
The tokens living on
#QuarkChain
’s ecosystem have the same rights as those enjoyed by native tokens
#QKC
& can take up more functional values such as contract deployment and payment of transaction fees!
With one click, every one can issue native token that has the same function as ETH!!!
To overcome limitations in functionality,
#QuarkChain
is now launching a unique multi-native token contract!
The first Multinative token will be announced soon.

Agree! The low fee is the door to open massive adoption of Web3! QuarkChain
@Quark_Chain
is designed to achieve this with sharding technologies! The mainnet has been running (and surprisingly smoothly) for more than 3 years!
@RyanSAdams
Needs to get under $0.05 to be truly acceptable imo. But we're definitely making great progress, and even proto-danksharding may be enough to get us there for a while!
