坎昆升级很可能将L2龙头拉升10倍以上，很多人只听别人吹牛皮坎昆升级，人云亦云，一头雾水，并不知道到底升级个什么玩意儿，老林是（技术型玩家）今天简短的给兄弟姐妹们讲一下。
1. 以太坊的升级命名方式:
- Ethereum has chosen to name its upgrades after the city where the developer conference is held. The origin of this naming scheme came from a number of naming suggestions, one of which was to name it after the city where the developer conference was held.
- Past examples include the Berlin upgrade and the London upgrade, and the most recent one is the Cancun upgrade expected in mid-November. Cancun is a transliterated Mexican city. This Ethereum Developer Conference was held in Cancun, Mexico. This is the origin of the name.
2. 上海升级的主要内容:
- The Shanghai upgrade allows unlocking the pledge and withdrawal of the ETH beacon chain. The beacon chain is the verification chain after ETH is converted from POW to POS, which handles pledges and sharding.
3. 坎昆升级和EIP-4844（proto-danksharding）主要内容:
- EIP-4844 will be the centerpiece of the Cancun upgrade. The purpose of this proposal is to meet the data and storage needs of blockchain applications through temporary storage and retrieval of data under the Ethereum node chain. There are other issues that we will talk about when we have time.
- If successfully implemented, EIP-4844 will significantly reduce transaction costs for Layer 2 solutions. The vernacular is that if the upgrade is successful, the speed of L2 will be increased by 10 to 100 times while reducing the cost. This will allow projects such as OP/ARB/ZKS to achieve higher throughput and greatly reduce gas fees. We all know that the current zone Blockchain is said to be decentralized, but in fact it can only be considered semi-decentralized. The biggest bottleneck of blockchain is its inability to achieve huge throughput and almost zero-cost transaction fees. For example, the throughput during Double Eleven will block the entire mainnet in an instant. Many brothers and sisters have experienced that it cost more than 100 U of GAS to transfer on the ETH chain.
4. 坎昆升级对哪些利好:
-OP/ARB/ZKS，目前ZKS先排除，至于OP和ARB选择哪个？成年人还需要做什么选择？当然是两个都要啊，兄弟们直接冲，这其中还要注意一个DYDX，GMX这类对吞吐量要求高的目标，这类也会受益。那么OP老林建议在1-1.5都可以分批干，ARB1以下闭眼干。形势好一点吃个1-3倍完全没问题，你要问到底二选一怎么选，关注老林，看下回详细分解。
This industry operates in a circle, because information has a great impact on it. If you don't have a circle and can't receive information at all, it will be easy for you to become a leek, and it will be difficult for a person to persevere. To put it bluntly, winning depends on the information gap. Many people have a feeling that the price goes down as soon as they enter, and then goes up as soon as they come out. This is because the information is not timely.
