Ethereum

USDC is a stablecoin issued by Circle that is pegged 1:1 to the US dollar and runs on multiple blockchains including Ethereum and Solana.

ENS (Ethereum Name Service) writes domain records onto the Ethereum blockchain, and users who hold the corresponding NFT have control over that domain

ERC-8004 is an Ethereum standards proposal still under discussion, aiming to define identity registration, capability declarations, reputation records and verification interfaces for agents.

ERC-4337 is the standard for implementing account abstraction on Ethereum and was officially deployed in 2023.

Ethereum nodes expose RPC methods such as eth_call, eth_getBalance and eth_sendRawTransaction by default, and clients can send structured requests via HTTP or WebSocket.

eth_call is a read-only call method in the Ethereum JSON-RPC interface that consumes no Gas, generates no on-chain transaction, and does not change blockchain state.

The on-chain cost of a hash is usually just a 32-byte storage slot, and even when gas prices on the Ethereum mainnet are high, the cost of a single submission is far lower than storing the full content.

MetaMask is the most widely used browser wallet and signing tool in the Ethereum ecosystem, whose core capability is managing private keys and cryptographically signing transactions or messages.

Merkle trees are underlying infrastructure in Git, IPFS, Bitcoin, and Ethereum, and Ethereum's state root and transaction root are both Merkle Patricia trees.

Ethereum, Cloudflare and others have all integrated or support IPFS gateways.

Blockchain irreversibility comes from its consensus mechanism design: Bitcoin makes the computational cost of rollback rise exponentially as the number of confirmations increases; after Ethereum's Merge shifted to proof of stake, a finality mechanism ensures that confirmed blocks cannot be easily reorganized.

The only part of the report with a complete structure is the crypto market snapshot, in which Bitcoin is quoted at $64,837, Ethereum at $1,921.95, Solana at $77.60, Dogecoin at $0.07, and XRP at $1.11.

Once a smart contract is deployed to mainnet, its code logic cannot be modified unless the contract has a pre-configured upgrade proxy pattern.

The core reason for choosing Base L2 over the Ethereum mainnet is that micropayments are extremely sensitive to gas costs, and mainnet fees could far exceed the value of a 0.05 USDC transaction itself.

CoreWeave accumulated a large GPU asset base through Ethereum mining in its early days, and pivoted to compute leasing after mining returns declined.

In The DAO incident of 2016, approximately $60 million worth of Ether was stolen, and the situation was ultimately remedied through a hard fork, which led to a community split.

After Ethereum completed its merge from proof-of-work to proof-of-stake in 2022, the primary use case for GPU mining disappeared, and large quantities of mining cards flooded the second-hand market with prices dropping sharply.

zk-SNARKs are widely used in blockchains such as Ethereum due to their small proof size and fast verification speed.
