以太坊「坎昆升级」目前又有新的进展：2023 年 12 月 8 日，在以太坊基金会的 176 次会议上，开发人员一致同意，如果事情进展顺利，将在 2024 年初定 Goerli 分叉日期，目标是能在 2024 年 1 月激活 Goerli Dencun 测试网。而关于以太坊「坎昆升级」最终完成的具体时间，根据行业人士对目前协议开发进度、测试完成进度的推测，预计能够在 2024 年 3 月~ 4 月期间正式实现升级。imToken 现已全面支持 Sepolia 测试网，通过「水龙头」入口支持 Sepolia 测试网的测试资产认领。
The significance of Ethereum's "Cancun Upgrade" is no less than that of the "Shapella Upgrade" - because this upgrade is the key to further expansion of Ethereum. It can increase the transaction volume that the Ethereum network can respond to per second, and will also open up Ethereum. A new stage in the development of data storage and retrieval capabilities.
For blockchain users who hold digital assets, the most intuitive change that Ethereum’s “Cancun Upgrade” will bring to digital asset transactions is that the Gas fees required for digital asset transactions on the Ethereum Layer 2 network will be significantly reduced. , the decline may reach 14 times.
imToken now supports all Layer 2 networks and EVM compatible chains on Ethereum. After the "Cancun Upgrade" is completed, users holding digital assets can experience the assets of the Ethereum Layer 2 network with higher cost performance and cheaper gas fees through imToken. trade. In addition, imToken supports OP and Polygon, and you can also enjoy relatively lower network operation costs by directly using the Swap function of imToken.
For blockchain developers, it is important to note that after the Ethereum "Cancun Upgrade" is officially implemented in 2024, the Goerli test network will no longer be used. It is recommended that developers migrate to the Sepolia test network as soon as possible.
imToken now fully supports the Sepolia test network, and supports the test asset claim of the Sepolia test network through the "faucet" entrance.
以下是「坎昆升级」值得重点关注的改进协议（简称 EIP），让我们一起了解。
The protagonist of "Cancun Upgrade": EIP-4844
Ethereum sharding prototype
▶ Improvement goals: Solve the scalability (i.e. expansion needs) of Ethereum, help reduce the transaction cost of Ethereum’s Layer 2 (Layer2) Rollups solution, and increase the speed of Rollups.
▶ Improvement background: The cost of the Ethereum Layer 1 mainnet (Layer1) has always been high, and necessary improvements are urgently needed to reduce the overall operating cost.
Currently, scaling solutions on Ethereum are primarily Layer 2 Rollups.
In practice, the Rollups solution helps users save a lot of operating costs (hereinafter referred to as Gas Fee). For example, on behalf of project Optimism, the regular cost of Gas Fee is only 0.001 gwei, which is far lower than the regular cost of the Ethereum layer 1 mainnet; ZK Rollups' solution has better data compression performance, does not require the inclusion of signature data, and is cheaper, even down to one percent of Ethereum's Layer 1 mainnet. However, for a wider range of users, gas costs are still a relatively expensive burden even after the Rollups solution. In addition, Ethereum's efficiency in processing parallel transactions is still low, and it can only handle double-digit transaction volume per second. These require new improvements to help improve scalability.
Sharding - is a powerful improvement method to solve the above problems, but it is not yet implemented in Ethereum. The timely proposal of the improvement plan EIP-4844 is to solve the above needs and implement the sharding upgrade. , found a trade-off that can be applied to Ethereum at the current stage, and laid an early technical foundation for Ethereum to achieve overall data sharding in the future.
Therefore, EIP-4844 was once called "Proto-danksharding", which is the "prototype of sharding". The word dank also has a different origin. It is taken from the name of Ethereum researcher Dankrad Feist. He once said: "EIP-4844 will become an accelerator for Rollups."
Currently, in order to more intuitively display the technical improvements of EIP-4844, the title of the EIP-4844 improved protocol has been uniformly described as "Shard Blob Transactions", that is, "Shard Blob Transactions".
Blobs were originally designed to help carry Ethereum layer 2 data. At the same time, Blob, this set of data vectors, is stored by the nodes of the Ethereum consensus layer, so it cannot be read by the Ethereum Virtual Machine (EVM) of the execution layer. It is this separation of data that achieves Reduced fees for Ethereum Layer 2 Rollups solutions. The Ethereum Cancun upgrade is expected to take place in the first half of 2024 and will include five IPs to enhance Ethereum’s scalability through proto-danksharding (EIP-4844) and a series of Ethereum Improvement Proposals (EIPs). Examples include modular scalability, lower gas costs and improved safety.
The Cancun upgrade will bring faster transaction processing times, lower transaction costs and optimized data management to Ethereum. This is definitely beneficial and helpful to the development of the Ethereum ecosystem.
