Web3 (310)

When it comes to safely storing your crypto, it’s widely recommended to withdraw your coins from an exchange and store them in a personal wallet, as the crypto industry has a saying — not your keys, not your coins. When it comes to choosing the type of wallet you wish to store your crypto in, there's a wide selection, such as hot wallets or cold storage — which are also known as offline storage wallets.

What are Merkle trees and how do they enable Proof of Reserves? You’ll often hear that some kinds of Proof of Reserves are based on “Merkle trees”. But what are they and how do they even work? Here’s

If Web3 is going to take over the globe, it's going to have to change. For some, DeFi, NFTs, dApps, DAOs, and everything in between have already been exciting enough to dive in. But, as all crypto users know, this exploration isn't without risk. And that risk can be ‌reason enough to stay away. Enter our latest feature, OKX Smart Account , an extension of our commitment to building the safest, most secure, and most affordable Web3 experience around.

One of the most important parts of the Bitcoin machine is Proof of Work (PoW) — a consensus mechanism that gives the decentralized ledger robust security.The concept of PoW first emerged with the arrival of Hashcash in 1993. Hashcash's creators, Moni Naor and Cynthia Dwork, devised a form of PoW to stop denial-of-service attacks and other abuses like spam. Doing so required some work from the person requesting the service, usually involving a computer’s processing time.

You might have heard of Proof of Reserves (PoR) but did you know there are actually different types of PoR, each giving more weight to different aspects? In this article we'll cover what these are, in

The ordinals protocol has gained popularity in the crypto space, with some seeing it as a way to create new protocols and BRC-20 tokens on the Bitcoin blockchain. Ordinals are also known as BTC NFTs and are considered digital artifacts. Once you mint your digital artifact, you can keep it in your wallet or sell it on a marketplace, similar to NFTs. You can learn more about their rarity in our .

Have you ever questioned what else the Bitcoin blockchain can provide besides a digital currency and ordinals ? ARC-20 introduces a fungible token standard to the Bitcoin blockchain, using satoshis — the smallest units of Bitcoin — as the backbone for token representation. This means each ARC-20 token is inherently backed by a satoshi, making sure a baseline value and integrating seamlessly with existing Bitcoin infrastructure.

How does decentralized finance (DeFi) work with Bitcoin ? And, what's next for Bitcoin? As we gear up for the next Bitcoin halving in 2024, these questions and others are on the coin community's mind.

Have you heard of the Runes Protocol? It's a unique addition to the Bitcoin environment, providing a fresh perspective on fungible tokens compared to protocols like BRC-20 and Taproot Assets. What makes it so different? Unlike other token standards, the UTXO-structured system incorporated into the Bitcoin network has an added focus on user-friendliness.

The Core blockchain was designed to expand Bitcoin's capabilities and bolster its scalability by combining Bitcoin’s lauded security with Ethereum’s strong smart contract capabilities. The project adopts Bitcoin’s proven security model through a Satoshi Plus consensus, and supports compatibility with the for users wanting to build decentralized apps (DApps). As such, Core merges the key strengths of crypto's two biggest assets for users.

The original decentralized finance (DeFi) sector has been around for years, but it only became big in 2020. After it got under the spotlight, a number of highly successful projects emerged. However, j

If you’re a fan of Elon Musk, you might want to consider adding X Empire to your tap-to-earn gaming collection built on TON . The mini-app features avatars with a likeness to the entrepreneur, alongside other figures from across popular culture that you can buy with your Telegram stars. This includes a muscular , and a Kardashian-esque character.

The fantastic thing about crypto is that developers are always building and coming up with new fixes for existing problems. As the Ethereum network grows, so to does demand for scalable and efficient solutions. Ethereum Layer-2 (L2) scaling solutions are therefore crucial in addressing the network's congestion and high transaction fees. One such L2 that's stepped up to the plate to solve the issue of scalability is Scroll. By leveraging (ZK) rollup technology, Scroll promises to be a zkEVM L2 that marries Ethereum's robust security with lower latency and better scalability.

When [Bitcoin](/price/bitcoin-btc) was first created, mining was a relatively straightforward process as it only required a personal computer and an internet connection. However, mining became increas

Sky is the new name for MakerDAO, a decentralized finance platform. Alongside its rebrand, Sky will be introducing a new stablecoin USDS (Sky Dollar) and a governance token, SKY. The platform is due to launch on September 18, and joins Ripple in presenting traders with a new stablecoin option.

In the dynamic world of cryptocurrency trading, decentralized exchanges (DEXs) have emerged as powerful platforms for onchain trading. By eliminating the need for intermediaries, DEXs effectively offer users greater control and flexibility. Among these leading DEXs, a notable one that's been gaining traction in the is Raydium.

The emergence of  ordinals  and  BRC-20 tokens  sparked a lively debate within the Bitcoin community. On the one hand, enthusiasts celebrated the newfound potential these innovations bring to the Bitcoin blockchain. On the other hand, concerns have been raised about the rise in gas fees, longer transaction times, and the potential occupation of valuable block space by ordinals and BRC-20 tokens.

Prediction markets pose an age old question: are the many truly smarter than the few? With prediction markets like Polymarket and Drift Protocol’s Bullish on Everything (BET) making headlines and gaining popularity, this question is more relevant than ever. Featuring the ability to forecast everything from election results to stock prices, these crypto prediction market platforms allow individuals to trade contracts based on the potential outcome of future events while tapping into the collective wisdom of the crowd. As these markets continue to grow and evolve, they offer a fascinating glimpse into the potential of crowdsourced intelligence.

Imagine a blockchain built for speed and designed to overcome the common challenges of decentralized trading — this is what Sei attempts to achieve. Sei aims to process transactions fast, while still being flexible enough to support everything from trades to gaming and NFTs.

Picture an app that isn't controlled by a single company and allows you to take back control of your data and privacy. This is what decentralized apps (DApps) are all about. Whether for decentralized finance (DeFi), gaming, or social, there’s a DApp for everyone. As such, the technology underpins many of today's most positively disruptive projects.

Sometimes, crypto projects with a meme-like concept can evolve to take on a new life with greater utility. One example is Berachain, which began life as the Bong Bears NFT project. At the 2024 edition of Token2049 in Singapore, Berachain’s anonymous co-founder, Smokey the Bera, explained that the team had noticed problems with how a number of blockchain networks worked today. Specifically, they realized that in many cases, liquidity and security weren’t aligned at the chain level. That led to Bong Bears taking on a new life as a Layer-1 blockchain that integrates with the Ethereum virtual machine (EVM).

Put simply, a nonce in crypto is a number that’s used once in a very specific way within the blockchain. Think of it as a unique one-time code that plays a key role in adding new data to the blockchain.In most blockchain networks, including Bitcoin, the nonce helps solve the complex puzzle that allows new blocks to be created. But here’s the thing — you don’t need to be a math whiz or a tech expert to grasp the basics. The nonce is part of how blockchain stays secure, making sure that all the transactions are valid and the network operates smoothly.
