FX168 Financial News Agency (Asia Pacific) reported on Thursday (May 15) that Ethereum rebounded slightly to around $2,629. The monthly increase of Ethereum/Bitcoin exceeded 30%, unexpectedly ending the decoupling trend. After the significant Pectra upgrade of Ethereum, the Ethereum Foundation (EF) announced the launch of a trillion-dollar security program.

According to a post update from "Wu Says Blockchain": "The Ethereum Foundation has announced the launch of a trillion-dollar security program aimed at comprehensively enhancing the security of the Ethereum ecosystem across various levels, including user experience, wallets, smart contracts, infrastructure, and consensus protocols."
The post continues to point out: "This project will advance through three main directions: full-stack security risk assessment, improvements in key areas, and more transparent information dissemination. The goal is to enable users to securely manage assets on-chain while supporting Institutions and governments in hosting trillion-dollar-level value on Ethereum. This project is led by Foundation members Fredrik Svantes and Josh Stark."

The Ethereum Pectra upgrade is an important protocol upgrade launched in 2025, combining two major upgrade components: Prague (execution layer) and Electra (consensus layer). This upgrade has sparked a bullish wave for Ethereum.
The following are the main improvements from this upgrade:
1. EIP-3074: Improving Account Abstraction Capability
Allows ordinary external accounts (EOA) to authorize contracts to initiate trades on their behalf;
Paves the way for future account abstraction (ERC-4337 or EIP-7702);
Enables features such as batch trades, signature delegation, and wallet experience optimization.
2. EIP-7251: Increase Validator Staking Limit
Increases the maximum staking amount for validators from 32 ETH to 2048 ETH;
Alleviates the network performance pressure caused by the current excessive number of validators;
Helps improve the efficiency of staking pools, but increases the risk of centralization slightly.
3. EIP-6110: Embedding staking information of the consensus layer into the execution layer's beacon chain.
Optimize the block building process to allow the execution layer to directly access the staking queue data.
Improve the processing efficiency of staking-related transactions and enhance on-chain transparency.
4. Preparatory work for Verkle Tree (may not go live immediately).
This is the key to the future "Stateless Ethereum".
Pectra may introduce some preparatory mechanisms, but the complete Verkle Tree is expected to be implemented in later upgrades.
With the astonishing rebound of Ethereum, the market is anticipating a larger "black swan" event, namely the decline of Bitcoin's dominance and more funds flowing into smaller altcoins, creating a new round of Altcoin Seasons.
However, Chinese crypto analyst Phyrex Ni stated: "Ethereum data is not very good; although (the spot ETF) only has net outflows from Grayscale, the only net inflow comes from Franklin Templeton. The overall market sentiment is still not good. A few days ago, there was a split between ETF investors and spot investors, and in recent days, both ETF and spot investors have been selling, so Ethereum's price pressure has increased somewhat."
Based on the current trend, Ethereum is still highly correlated with Bitcoin and is also affected by macroeconomic factors, but compared to Bitcoin and the US stock market, it is more influenced by liquidity. For Ethereum to emerge with an independent market trend, a distinct narrative is needed. Today, the Russell 2000 has also begun to decline." he continued.
