关于【Blockchain】问题列表

As someone working in the tech industry in the U.S., I’m worried about the ongoing wave of IT layoffs and tech layoffs that seem to hit every few months. I’ve seen reports of big tech layoffs at companies like Microsoft, Amazon, and Meta, and it’s making me anxious about job security.

Are layoffs in tech still happening in 2025, or is there an end in sight? I want to know what’s driving these layoffs, if tech companies are still laying off, and when we might see some stability.

I’m also curious about how this affects opportunities in emerging fields like cryptocurrency or blockchain.The news about big tech layoffs is everywhere, and it feels like even profitable companies are cutting jobs.

Decentralized applications (dApps) like those in the DeFi and NFT space need to access and display a massive amount of data from the blockchain. However, getting this data directly from a blockchain is like trying to find a specific book in a library with no catalog system; it is slow, inefficient, and resource-intensive. The Graph was created to solve this fundamental problem.

What is The Graph?

The Graph is often called the 'Google of Blockchains'. It is a decentralized protocol for indexing and querying data from blockchains, starting with Ethereum. It allows developers to easily search for, find, and use blockchain data without needing to run their own complex infrastructure. In essence, it creates a well-organized, global catalog for the public data stored on blockchains, making it easily accessible for everyone.

How The Graph Works: The Network Roles

The Graph's ecosystem is powered by several key participants who work together to ensure data is indexed accurately and served quickly.

Subgraphs

A subgraph is a custom, open API that defines what data to index from a blockchain and how to store it. Each dApp can build its own subgraph to track the specific data it needs, such as NFT ownership records or DeFi trade histories.

Indexers

Indexers are the node operators of the network. They stake The Graph's native token, GRT, to provide indexing and querying services. They run the software that processes the information defined in a subgraph and are rewarded with GRT for their work.

Curators

Curators are participants who signal which subgraphs are high-quality and should be indexed by the network. They stake GRT on a specific subgraph to indicate their belief in its importance and accuracy, earning a portion of the query fees for that subgraph.

Delegators

Delegators are individuals who want to contribute to securing the network without running a node themselves. They can delegate their GRT to an existing Indexer and earn a portion of that Indexer's rewards and fees.

The Role of the GRT Coin

The GRT coin is the essential utility token that coordinates the entire Graph network. It is an ERC-20 token on the Ethereum blockchain and is used for several critical functions. It is used for staking by Indexers and Curators, for delegating by Delegators, and as the means of payment for dApps that consume the data services. This creates a complete economic cycle where all participants are incentivized to act in the best interest of the network.

The Investment Perspective

Investing in The Graph's GRT coin is a bet on the future growth of the entire Web3 and dApp ecosystem. The Graph is not a dApp itself; it is a piece of critical, foundational infrastructure that nearly all dApps will need to operate efficiently. As the number of dApps grows, the demand for The Graph's data indexing services is expected to grow as well. This positions The Graph as a "picks and shovels" investment for the broader adoption of decentralized technology.

Why Ethereum Gas Fees Are So High—and How to Save on Your Crypto Transactions

If you’ve ever tried trading, swapping, or interacting with decentralized applications (DApps) on Ethereum, you’ve probably felt the sting of gas fees. These mysterious charges can hit your wallet hard, especially if you’re simply sending ETH or minting an NFT. Questions like  Why are Ethereum gas fees so high?  or  What are gas fees in crypto?  are on the minds of countless users worldwide. In this article, we’ll break down Ethereum gas, explain what gas fees really mean, and explore practical ways to save on transactions—whether you’re a beginner in the U.S., an experienced trader in Europe, or a DeFi enthusiast anywhere in the world.

Understanding Gas Fees in Crypto

Think of gas fees as the fuel that powers Ethereum. Every transaction—whether sending ETH, trading tokens on Uniswap, or using a DApp—requires computational effort from miners or validators. Gas fees compensate them for their work and keep the network secure.

These fees aren’t arbitrary. They serve multiple purposes: they incentivize miners and validators to process transactions, help the network prioritize urgent transactions, and reflect the complexity of your action. A simple ETH transfer requires much less gas than executing a complex smart contract.

For instance, if you’re trading on a platform like OpenSea in the U.S., fees can range from a few dollars to hundreds, depending on network congestion. This unpredictability frustrates users around the globe, from London to Tokyo.

Why Are Ethereum Gas Fees So High?

High Ethereum gas fees are no accident—they’re the result of several interconnected factors.

Network Congestion: Ethereum powers thousands of DApps, NFTs, and DeFi projects. Whenever a major NFT drop or yield farming opportunity happens, millions of users rush to the network at once. This competition drives gas prices up as users bid higher to get their transactions processed first.

Gas Price Mechanics: Gas fees are calculated . Gas units represent the computational work your transaction requires, while gas price (measured in Gwei) is what you’re willing to pay per unit. During periods of high demand, users increase their gas price to prioritize transactions, sometimes causing fees to skyrocket to $200 or more for complex actions.

Ethereum’s Scalability Limits: Currently, Ethereum handles only about 15–30 transactions per second, compared to Visa’s 24,000 per second. Until upgrades like Ethereum 2.0 and sharding are fully implemented, high gas fees remain a persistent issue.

Global Demand and Currency Factors: For traders in countries with fluctuating local currencies, fees can feel even higher when converted into local money. A $30 transaction may be minor in the U.S. but could represent a significant cost elsewhere.
