So, Proof of History (PoH) is the mechanism that Solana uses to make the blockchain more efficient. I just realized how fundamental this concept is for understanding why Solana can be fast and cheap.
In traditional blockchains, the network needs to reach consensus on two things at the same time: which transactions are valid and what order they should be in. Timing is crucial because it tells everyone when a transaction happens. If there’s no clear timestamp, the blockchain becomes chaotic.
Proof of History is basically a solution to this timing problem. PoH is a system that embeds time directl

Did someone ask how much 1k is on the exchange earlier? Okay, I'll explain briefly about the common units we often see on exchanges, so you won't be confused anymore.
So, here it is, when we look at charts or trading volume, there are some abbreviations that need to be understood:
1K means 1k. Most often appears when we see prices or volume in a more concise format.
1M means 1 million. Quite frequently used, especially when talking about market cap or larger volumes.
1E is equal to 100 million. This is less commonly used compared to the others, but it's still important to know.
1B is 1 billion

I just read about the debate over whether forex trading is halal or haram among Muslims, and it turns out this is more complex than I thought.
So, basically, forex trading is the process of buying and selling currencies on the international market with the goal of making a profit from exchange rate changes. Many people do this, from individual investors to large financial institutions.
But the problem arises here. From an Islamic perspective, physically exchanging currencies isn't an issue. However, most online forex platforms charge interest and fees for leverage, and in Islamic finance, inte

I was just pondering a question—how many people truly understand Vitalik Buterin’s impact on the entire blockchain ecosystem? This guy didn’t just write a white paper; he fundamentally changed how people perceive decentralized technology.
Let’s start with the current situation. Last year (2025), the Ethereum Foundation announced that Vitalik would step back from daily coordination work to focus on long-term research. This decision is quite interesting—on one hand, it aims to push further decentralization of leadership; on the other, it gives him more space to explore cutting-edge ideas. But ho

I just thought about it, and it turns out many people are still confused about the difference between crypto and forex. But these are two completely different trading worlds, actually.
So here’s the thing—if you trade forex, you’re basically trading foreign currencies like EUR/USD or GBP/JPY. The forex market is super liquid, the transaction volume is huge, and it’s relatively more stable. But the important part is: forex is open only from Monday to Friday—24 hours a day, but it’s really just 5 days. Plus, the regulations are already clear in various countries.
This is totally different from c

I recently discussed SND trading with some traders, and it turns out many of them still don't fully understand how to use these supply and demand zones effectively. In fact, this is one of the most useful skills for crypto trading.
So, supply and demand are basically two fundamental concepts that determine where the price will move. Supply is an area where there are a lot of sellers ready to sell, so the selling pressure here is high. Conversely, demand is a zone where buyers are interested in buying because the price is considered attractive. Simply put, supply is a dominant seller zone, and

I’ve been thinking lately about pump and dump, the scheme that most often traps investors in the crypto market. The term is actually simple—pump means raising the price, dump means selling or disposing of a large amount. But how it works can cause many people to lose money.
So, what’s the scheme like? It usually starts with a group of people buying a large amount of crypto assets. After that, they begin spreading positive news, whether exaggerated or even false, through social media, forums, Telegram groups, or Discord. The goal is clear—create hype and attract other investors to buy in. When

Bitcoin is dropping again, and if we look at history, there are usually more pressures before the bottom is formed. Currently, the price has reached a fairly low level, but historical patterns indicate that volatility can still continue. It's interesting to observe how support levels react at this point. From trading experience, every time there's such a significant decline, the recovery doesn't happen immediately—there's a consolidation phase first. So there might still be time to see further developments before the trend changes. Anyway, history is the best teacher to understand what could h

Bitcoin RSI now shows a quite interesting oversold signal to watch. This is one of the most reliable technical indicators we can use in trading.
RSI or Relative Strength Index is a formula that measures the speed and magnitude of price changes. When RSI drops below 30, it usually indicates an oversold condition, which means there is potential for a price reversal upward.
From what I see, this oversold level could be an opportunity for traders looking for an entry point. But keep in mind, oversold does not mean the price will immediately rise. It's best to wait for confirmation from other indic

I just found out that there are soldiers who were arrested by the US because of something related to betting on Polymarket about Maduro's raid operation. It seems to be what you call the risk when people start placing bets on sensitive geopolitical events on prediction market platforms. Polymarket itself is becoming more popular for betting on all kinds of things, from election results to more controversial matters like this.
So, apparently, there’s a soldier caught involved in bets related to an operation involving Maduro. This is interesting because it shows how decentralized betting platfor

Recently, there has been an interesting development from the Czech Republic. Their central bank, which was the first to conduct a trial of Bitcoin, ultimately concluded that this crypto asset is too risky to be part of their foreign exchange reserves.
This conclusion is significant because the Czech Republic is one of the more open countries in exploring Bitcoin's potential. However, after a thorough evaluation, they arrived at a conservative decision. The reason is simple: Bitcoin's volatility and risk profile do not align with the needs of stable currency reserves.
This shows that although B

Serius, kalau kita bicara tentang revolusi Web3, holo adalah salah satu proyek yang paling underrated di sini. Gue baru-baru ini deep dive ke teknologinya dan honestly, ini bukan sekadar token crypto biasa — ini adalah cara berpikir yang completely berbeda tentang internet terdesentralisasi.
Jadi ceritanya gini. Blockchain tradisional itu basically memaksa semua node untuk agree pada setiap transaksi. Bayangkan kalau setiap keputusan di pemerintahan harus vote semua orang — itu inefficient banget, right? Nah, Holochain yang jadi fondasi holo adalah mengambil pendekatan yang totally different.

Just saw a photo of young Trump with his first child Ivanka, they look very similar. Since childhood, he has been given the best education, and often accompanied his father to various events. It seems like big families really have their own way of raising children.
By the way, I’m looking at the chart today. BTC is still holding at 82.29K with a 0.93% increase, ARB is also quite good with +4.63%. GTC is quiet, but who knows, it might move later. Is anyone monitoring the market right now?

So I was scrolling and thinking, why are so many people talking about crypto faucets that can provide passive income? I'm curious, and it turns out there are ways to maximize the results, not just by clicking around. If you're serious about collecting crypto from here, you need the right strategy, not just random actions.
The most important first step is not to rely on just one faucet. I used to focus only on one platform, and the results were just so-so. But once I opened several different faucets like Cointiply, FaucetPay, and Bitcoinker, the earnings started to feel different. Basically, ev

Lately, I’ve noticed that many people are interested in finding tokens with low prices but strong fundamentals for long-term investment. Actually, there are options—but you do need fairly serious research before deciding to get in.
For example, Algorand’s blockchain technology is fast, with very low transaction costs, and it’s also environmentally friendly. Its DeFi and NFT ecosystems there are starting to grow, so it’s definitely worth watching. The current price of ALGO is $0.11, down -1.06%—it’s still quite accessible for beginners who want to start investing in cheap crypto.
Then there’s H

Jadi kemarin ada yang tanya ke saya, sebenarnya gimana sih cara membuat koin crypto sendiri? Pertanyaan yang bagus, tapi jawabannya ternyata lebih kompleks dari yang dibayangkan.
Sebelum mulai, perlu dimengerti dulu ada dua pilihan utama: koin atau token. Bedanya cukup fundamental. Koin punya blockchain sendiri, seperti Bitcoin atau Ethereum. Token dibangun di atas blockchain yang sudah ada, kayak CAKE di Binance Smart Chain. Kalau ditanya mana yang lebih mudah, token jelas menang. Token bisa dibuat dalam hitungan menit, sementara koin butuh tim developer dan waktu berbulan-bulan.
Kalau mau ta

So recently I've started noticing an interesting trend in the crypto market—more and more people are talking about Real-World Assets (RWA). The concept is simple: assets from the real world like real estate, bonds, or even gold, can now be tokenized and transferred onto the blockchain. It's not just hype, but there are concrete reasons why RWAs are gaining popularity.
The most significant factor is that major institutions are taking this seriously. BlackRock and JPMorgan have already experimented with blockchain-based bond tokenization. Not only that, regulations are becoming clearer in some c

Hey everyone, I want to share about the blockchain structure that often causes confusion, especially regarding L0, L1, L2, and L3. This is really important for understanding how blockchain technology develops.
So, imagine blockchain as a pyramid—each layer has a different role. L0 is the most basic foundation. L1 is the main part that forms the backbone. L2 is the upper layer that adds features. Then L3 is the application we use directly every day.
Starting from the bottom, L0 is like a data transmission system. It handles the transmission of information between nodes in a blockchain network,

Most people don't know there are hidden features in DEX Screener that can change the game. Only a handful of traders truly maximize these tools, and they've caught meme coins 100x much earlier than others. I want to share their strategies and how to find the next gem.
DEX Screener is very powerful for tracking and analyzing price data of pairs directly from the blockchain. But honestly, most users only use its basic features. In today’s competitive market, timing is everything. The earlier you get in, the greater your profit potential.
So where to start? First time you open DEX Screener, check

I recently talked with several traders, and it turns out many are still confused about how to read supply and demand on the chart. In fact, this concept is a fundamental and super important basis if you're serious about crypto trading.
So here’s the thing, supply and demand are actually pretty simple. Supply is an area where many sellers are ready to offload their assets, so the selling pressure there is very high. Conversely, demand is a zone where buyers are interested in buying because they think the price is good. Both of these areas often become turning points for price, and that’s why it
