When Will Tech Layoffs Stop? Understanding IT and Big Tech Layoffs in 2025

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.

Why ERC-1155 Is the Future of Gaming, Art, and Crypto Assets

The Game-Changing Token Standard Revolutionizing NFTs and Beyond

So, you’ve probably heard about ERC-20 and ERC-721, right? One gave us fungible tokens like regular cryptocurrencies, and the other gave us NFTs. But now there’s something new that’s quietly shaking things up: ERC-1155. And honestly, if you’re into crypto at all — whether you’re trading in the U.S. with dollars or building projects in Singapore — this is one standard you’ll want to understand.

ERC-1155 is being called the  multi-token standard.  Sounds technical, but here’s the simple idea: it lets you create and manage different kinds of tokens all inside one smart contract. That includes fungible ones, unique NFTs, and even those in-between  semi-fungible  tokens. Why is that such a big deal? Let’s walk through it.

What Makes ERC-1155 Different?

Imagine you’re gaming. You’ve got a stack of in-game gold coins and a rare sword you picked up on a quest. With the old standards, sending those to a friend meant two separate transactions. That means two approvals, two fees, and double the wait. Pretty annoying, right?

With ERC-1155, you can move both in one go. Just like that — done. One transaction, less money wasted on gas, and less stress. It feels like the blockchain is finally catching up to how people actually use it.

Why People Care About This

Let’s be real: gas fees and clunky processes have been the biggest complaints about Ethereum for years. ERC-1155 is like a breath of fresh air because it solves exactly that. Batch transfers make life easier, and the fact that a single contract can hold so many types of tokens just makes sense.

But the versatility is what really excites me. These tokens can represent almost anything. A concert ticket that’s interchangeable until showtime? That’s possible. A digital art collection where some pieces are rare and others are common? Easy. Even property ownership broken down into shares plus a single proof of ownership NFT? All doable under the same contract.

And don’t overlook the safety side. Losing tokens because they went to the wrong address used to be a nightmare. ERC-1155 has safe transfer rules built in, which feels like Ethereum finally learning from years of user mistakes.

Peeking Under the Hood

Here’s the technical magic, but I’ll keep it simple. ERC-1155 uses token IDs. Each ID can represent something completely different. One ID might equal 500 in-game coins. Another ID is tied to a unique digital painting. And they’re all handled by the same contract.

The standard also lets metadata — basically, the description and artwork of a token — live off-chain in places like IPFS. That keeps Ethereum from getting clogged while still giving you rich details for each asset.

Real Examples You Can See Today

This isn’t just theory. Games like The Sandbox are already using ERC-1155 to handle currencies, items, and collectibles. If you’ve ever tried to trade in a game and hated the fees or lag, you’ll immediately see why this matters.

On the art side, marketplaces like OpenSea jumped on board because artists can drop collections with varying rarity without setting up ten different contracts. It’s smoother for creators and buyers.

And real estate? Picture a villa in Dubai tokenized into shares for investors, while a separate NFT acts as the ownership proof. That’s ERC-1155 in action. Even DAOs are using it for governance tokens plus unique membership NFTs — all in one place.

Why Developers Love It

For developers, this isn’t just cool, it’s practical. Deploying one contract instead of ten saves money and headaches. It’s scalable, too, so projects can grow without collapsing under high fees. For businesses, that means happier users. For traders and collectors, it means assets that are cheaper to move and safer to hold.

Understanding Blockchain Technology: A Simple Guide for Everyone

How Does Blockchain Work?

If you’ve been anywhere near the internet lately, you’ve probably heard the term blockchain thrown around. From cryptocurrency enthusiasts in the United States to tech innovators in Singapore, everyone’s talking about what is blockchain and how does blockchain work.

But what exactly is this game-changing technology, and why should you care? Whether you’re a curious newbie or a seasoned trader looking to understand blockchain technology better, this guide will break it down in a way that’s clear, engaging, and actionable.

Buckle up as we dive into the world of blockchain—a decentralized, secure, and transparent system that’s reshaping finance, supply chains, and even healthcare!

What Is Blockchain?  Basics

At its core, blockchain is a digital ledger that records transactions across many computers. Think of it as an unbreakable chain of data blocks, each linked to the one before it. This technology ensures that once information is added, it’s nearly impossible to alter, making it a trust machine for the digital age.

Key Features of Blockchain Technology

1. Decentralized: No single authority controls the blockchain. It’s run by a network of computers (nodes) worldwide, from New York to Tokyo.
2. Transparent: Every transaction is visible to all participants via a blockchain explorer, ensuring accountability.
3. Secure: Advanced cryptography locks each block, protecting data from tampering.
4. Immutable: Once a transaction is recorded, it’s permanent—perfect for financial records or contracts.

If you’re wondering what is a blockchain in simpler terms, imagine a shared Google Doc where everyone can see changes, but no one can edit past entries without consensus. That’s the magic of blockchain!

Ethereum Gas Fees Demystified: A Beginner’s Guide to Saving

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.

How to Reduce Ethereum Gas Fees

Crypto Node: Do You Get Paid for Running a Crypto Node?

You've gone down the crypto rabbit hole. You understand that a decentralized network isn't run by a single company, but by a global community. And you know that the computers powering this community are called nodes.

This leads to a very logical and exciting question: if you contribute your own computer and run a node, will the network pay you for it?

The direct answer, in most cases, is no. Running a standard, non-specialized crypto node does not earn you direct financial rewards.

But don't click away. Understanding why this is the case is one of the most important lessons in crypto. It will help you avoid scams and see where the real opportunities are. Let's break it down.

The Role of a Standard Node: The Volunteer Librarian

Think of a standard full node (like a Bitcoin Core node) as a volunteer librarian for the network. Its job is to:

• Hold a full copy of the blockchain (the entire library of books).
• Check new transactions to make sure they follow the rules (ensure the books are legitimate).
• Share this information with others.

These librarians are essential for the health, security, and integrity of the network. But they are volunteers. They do it to support the project, for enhanced personal security, or for the ideological belief in decentralization. They do not receive a "paycheck" from the network.

So, Who Does Get Paid? The Specialized Nodes

This is where the confusion usually starts. There are two special types of nodes that do get paid, because they perform an extra, energy-intensive job: creating new blocks.

As you can see, getting paid requires a significant investment in either specialized hardware (for mining) or a large amount of capital (for staking).

A Warning: The "Nodes as a Service" (NaaS) Trap

You have likely seen projects that let you "buy a node" and promise very high daily returns (e.g., 1% per day).

You must be extremely cautious. Many of these projects are not selling you true, productive blockchain nodes. They are often Ponzi schemes that use the money from new investors to pay the promised returns to earlier investors. When the new money dries up, the project collapses, and investors lose everything. Always ask the critical question: "Where is the revenue that pays for this yield actually coming from?"

The Real Benefit

While a standard node won't make you rich, it provides you with the highest level of financial self-sovereignty and security possible. It's a powerful tool, but not a direct source of income.

Instead of trying to earn from a standard node, a more direct strategy is to invest in the robust cryptocurrencies that are secured by thousands of them.

What Is Kaspa (KAS)? A Guide to the Instant-Confirmation Blockchain

For years, the crypto world has been dominated by a single design: the blockchain. But what if a different, more efficient structure could solve the industry's long-standing scalability problems? This is the question that Kaspa (KAS) answers.

Kaspa is not just another Layer-1 blockchain. It is the world's first BlockDAG—a next-generation ledger that allows for parallel blocks and near-instant transaction confirmations. It aims to be the fastest, most scalable, and most secure Proof-of-Work project ever built.

In this guide, we'll dive into what the Kaspa blockchain is, the technology that powers it, and the role of the KAS crypto coin.

The Core Innovation: Solving the Trilemma with GHOSTDAG

To understand Kaspa, you must first understand the problem it solves. Traditional blockchains are like a single-lane road—secure, but slow. Kaspa's BlockDAG architecture is a multi-lane superhighway.

The specific protocol that makes this possible is called GHOSTDAG. Here’s what it does:

• Allows Parallel Blocks: Instead of forcing miners to compete to produce one block at a time, GHOSTDAG allows multiple blocks to be created simultaneously.

• Creates an Interwoven Structure: The protocol then efficiently weaves these parallel blocks together into a cohesive structure, allowing the network to confirm a massive number of transactions at once.

• Maintains Order: GHOSTDAG provides a clear and reliable way to order all the transactions, even though they were produced in parallel.

The result? Kaspa is able to achieve an incredibly high block rate—currently one block per second, with plans to increase this to 10 or even 100 per second. This means your transaction can be fully confirmed in just a few seconds, not minutes or hours.

Key Features of the Kaspa Blockchain

1. Unprecedented Speed: Near-instant transaction confirmations make KAS suitable for everyday use.
2. Massive Scalability: The BlockDAG structure is designed to handle a huge volume of transactions without becoming congested.
3. Decentralized and Fair Launch: Kaspa had no pre-mine, no pre-sales, and no coin allocations to the team. It was launched fairly and is a 100% community-driven project, just like Bitcoin.
4. Proof-of-Work Security: Kaspa uses a Proof-of-Work consensus mechanism, which is widely considered the most secure and battle-tested model for a decentralized network.

The Role of the KAS Coin

The native currency of the ecosystem is KAS. The KAS coin serves two primary functions:

• Mining Rewards: It is used to reward the miners who secure the network by processing transactions.
• Network Transactions: It is the currency used to send and receive value across the Kaspa network.

The investment approach

An investment in the Kaspa crypto is a bet on the belief that the BlockDAG is a technically superior evolution of the blockchain. It's for those who believe that a truly scalable, decentralized, and instant Proof-of-Work digital cash system is still a problem worth solving.

With its fair launch and passionate community, Kaspa represents one of the most significant new technological advancements in the crypto space.

What Is Mantle (MNT)? A Modular L2 Blockchain

The landscape of Ethereum Layer 2 scaling solutions is highly competitive, with numerous projects all aiming to solve the challenges of high fees and slow transaction speeds. In this crowded field, Mantle has emerged as a significant player, not just for its technology, but for its unique structure and substantial financial backing. It represents a different approach to building a scalable and efficient blockchain environment.

What is Mantle

Mantle is a high performance Layer 2 network built on top of Ethereum. Its primary goal is to provide a scalable environment for decentralized applications, offering significantly lower transaction costs and higher throughput than the Ethereum mainnet. By processing transactions on its own chain and then submitting the data back to Ethereum, Mantle inherits the security of the main network while providing the performance benefits of a dedicated scaling solution.

The Modular Blockchain Approach

The key technological differentiator for Mantle is its modular architecture. Traditionally, most blockchains are monolithic, meaning a single layer of nodes is responsible for all key functions: executing transactions, ensuring data is available, and reaching consensus. Mantle separates these jobs. It uses a specialized data availability layer, leveraging EigenDA technology, to handle data, while another layer focuses on execution. This is like having an assembly line with specialists for each task, designed to be more efficient and flexible than one person doing all the work.

The Role of the MNT Token

The Mantle ecosystem is powered by its native utility and governance token, MNT. The token serves two primary functions. First, it is the gas token for the Mantle network, meaning users need MNT to pay for transaction fees when interacting with applications on the chain. Second, MNT functions as a governance token. Holders of MNT can vote on proposals that direct the future of the Mantle ecosystem, giving the community control over the protocol's development and treasury.

A Treasury Backed Ecosystem

A unique advantage for Mantle is its origin. The project was initiated by BitDAO, one of the world's largest decentralized treasuries. This provides the Mantle ecosystem with significant financial resources to fund development, incentivize builders, and drive adoption. This large treasury is a strategic asset, allowing Mantle to support a new generation of decentralized applications and attract both users and developers to its modular blockchain.

The Dark Side of Crypto: Why Blockchain Hacks Keep Rising and How Security Can Save You

Hackers Are Stealing Billions from Blockchains – Here's How Security Saves Your Crypto Fortune

Fortunes can change in an instant. But behind the excitement, one terrifying reality keeps traders awake at night: hacks. Just last year, blockchain exploits wiped out more than $3.7 billion from users worldwide—an amount bigger than the GDP of some small nations. Whether you are trading Bitcoin in the US, converting EUR in Europe, or just starting out in Asia’s booming crypto scene, the question inevitably comes: what is blockchain security, and why does it matter before I lose everything I own?

I’ve been writing and working in this industry since the ICO mania of 2017, through the NFT explosion, and now into the Web3 era. I’ve seen people make millions, and I’ve seen others lose everything in a single click. This isn’t just tech jargon—it’s survival. In this guide, we’ll explore what blockchain security really means, why it matters now more than ever, the hidden threats traders face every day, and most importantly, the practical steps and tools you can use to keep your crypto safe.

What Is Blockchain Security? The Foundation You Can’t Ignore

At its core, blockchain security is the set of technologies, practices, and safeguards that protect networks from threats such as unauthorized access, fraud, and outright theft. Blockchain itself is often described as  unbreakable  because it’s a distributed ledger shared across thousands of computers worldwide. But in reality, it’s only as secure as the people using it.

Imagine you’re trading stablecoins in New York, or moving funds across exchanges in Europe. One careless click on a phishing link could empty your wallet in seconds. This is where blockchain security comes into play. Through cryptography, consensus mechanisms, and decentralization, the system works to verify transactions, prevent double-spending, and maintain trust without a central authority. But those protections only work if you, the user, follow good practices.

For beginners, one of the best first steps is using a hardware wallet like Ledger. Unlike hot wallets, which are always connected to the internet, hardware wallets keep your private keys offline—making them far harder to hack.

Why Blockchain Cybersecurity Matters More Than Ever in 2025

With adoption soaring—over 420 million people now use crypto worldwide—the stakes have never been higher. Reports from Chainalysis reveal how sophisticated hacker groups, including nation-state actors, now target DeFi protocols and exchanges with surgical precision. We’re no longer dealing with amateurs; we’re up against organized cybercrime.

The numbers tell the story clearly. Blockchain exploits rose 15% in 2024, with smart contract bugs responsible for nearly 70% of losses. Cross-chain bridges, which allow assets to move between networks like Ethereum and Solana, saw attacks surge by 40%. And if you think the big players are immune, remember the $625 million Ronin bridge hack in 2022—proof that even massive projects can collapse under pressure.

For users in Europe, there’s the added concern of GDPR compliance and privacy. In emerging markets like Brazil or India, inflation and currency volatility mean a single hack can erase life savings. And for veterans who’ve traded through every bull and bear cycle, it’s impossible to forget that weak security almost always leads to catastrophic losses.

The Hidden Threats Traders Face

The danger often comes not from the blockchain itself, but from human behavior and weak points around it. Countless users have been fooled by phishing schemes—fake emails from exchanges, lookalike websites, or malicious Telegram bots. Others fall victim to vulnerabilities inside smart contracts, poorly written code that hackers exploit to drain liquidity pools.

Then there are wallet attacks. Hot wallets, such as browser-based ones, are convenient but notoriously risky. Cold wallets offer better protection, but they require discipline and planning. And while 51% attacks—where someone gains majority control of a network—are rare for giants like Bitcoin, they’re devastating for smaller blockchains.

Blockchain Security in Action: Real-World Protection

Despite the dangers, security is not just about fear—it’s also about empowerment. The right tools and practices transform blockchain into one of the most secure technologies ever invented. Real-world use cases prove this every day: IBM’s Food Trust uses blockchain to authenticate supply chains, Estonia uses it to secure digital voting, and financial platforms implement it for cross-border payments.

For everyday traders, the strategy is simpler but just as critical. Auditing your setup with tools like Etherscan ensures your transactions are legitimate. Diversifying assets across multiple chains reduces the risk of a single-point failure. Staying updated with major network upgrades, such as Ethereum’s Dencun, ensures you benefit from new layers of built-in protection.

And perhaps most important of all: education. Understanding the risks and the tools available is the single most effective way to avoid becoming another statistic.

Choosing the Right Tools: A Commercial Guide

For those ready to make smart choices, here’s a comparison of the most popular security tools and wallets. This table includes everything from beginner-friendly options to advanced platforms for professional traders. Notice that I’ve also added BYDFi, a growing global trading platform that combines user-friendly design with strict compliance and security, making it a strong alternative for traders who want peace of mind.

The Future of Blockchain Security

Looking ahead, the technology will only get stronger. Quantum-resistant encryption is already in development, designed to withstand the power of future supercomputers. Zero-knowledge proofs are gaining momentum, allowing for completely private transactions. And AI-driven monitoring systems like Forta are catching suspicious activity in real time, stopping hacks before they happen.

In the aftermath of FTX and countless rug pulls, one truth has become clear: trust is not given, it’s earned. Platforms like BYDFi, Gemini, and other secure players know this well, and they’re building their reputations on transparency, compliance, and robust security features.

For traders, the lesson is simple. Security is not an optional add-on—it’s the foundation. Whether you’re a curious beginner searching for  what is blockchain security or a professional investor looking for the safest wallets and platforms, the reality is the same: your crypto fortune lives or dies by the protections you put in place today.

What Is Shibarium? A Guide to Shiba Inu's Layer 2 Blockchain

For the Shiba Inu ecosystem to evolve beyond a simple token, it faced a major roadblock: the limitations of its home, the Ethereum blockchain. While secure, Ethereum can be slow and expensive, making it difficult to build high-speed games, DeFi applications, or mint affordable NFTs.

The community needed a solution. They needed their own high-speed highway. That highway is Shibarium.

In this guide, we'll explain what the Shibarium blockchain is, how this Shiba Inu Layer 2 works, and why it's a critical step in the project's long-term vision.

What is a Layer 2 Blockchain

Shibarium is a Layer 2 (L2) blockchain built on top of the Ethereum network. The easiest way to understand this is to think of Ethereum as a main highway that is often congested with traffic. A Layer 2 solution like Shibarium acts as a fast, efficient express lane built alongside the main highway. It processes transactions on its own chain, and then bundles them up to send back to the main Ethereum network for final settlement, inheriting its security.

The Problems Shibarium Solves

The primary purpose of Shibarium is to dramatically improve the user experience within the Shiba Inu ecosystem. The most significant advantage is the drastic reduction in transaction costs, often called gas fees. This makes small transactions, which are essential for things like gaming and decentralized applications, economically viable. Another key benefit is increased transaction speed, providing near instant confirmations instead of the potentially long waits on the main Ethereum network.

The Role of the BONE Token

To power this new network, Shibarium uses the BONE token as its native gas token. Every transaction that occurs on the Shibarium blockchain, from a simple token transfer to a complex smart contract interaction, requires a small amount of BONE to be paid as a fee. This creates a fundamental utility for the BONE token, as its demand is directly linked to the amount of activity and adoption that Shibarium achieves.

[To learn more about the fuel for this network, read our full guide: What Is BONE Coin?]

Impact on the Shiba Inu Ecosystem

By providing a faster and cheaper environment, Shibarium aims to transform Shiba Inu from a meme coin into a comprehensive, decentralized ecosystem. It opens the door for the development of a wide range of applications, including decentralized exchanges (DEXs), blockchain based games, metaverse projects, and other DeFi protocols. This infrastructure is designed to attract developers and users, fostering a self sustaining economy built around the SHIB, LEASH, and BONE tokens.
