What Are Crypto Futures, Coinbase's Latest Offering?

Coinbase announced on September 28, 2023 that it plans to launch its regulated perpetual futures contracts on its Coinbase Advanced platform (initially for non-US customers). Why futures? Partly because they offer investors a way of potentially taking advantage of the high volatility of most crypto. Let's use Bitcoin as an example. Spot trading—the practice of buying and selling Bitcoin—forces traders to exchange cryptocurrencies at their current prices. But what if there was a way to lock in t...

What Is a Bitcoin ETF, and Why Does Everyone from Blackrock to Grayscale Want One?

Want to earn a free on-chain certificate showcasing your Bitcoin knowledge? Take our free course, Getting Started with Bitcoin. Many of the crypto-curious still view buying Bitcoin from a crypto exchange as an intimidating and opaque process. The technical aspects of holding Bitcoin—such as crypto wallets, Bitcoin addresses and private keys—are confusing to newcomers, and scare some investors away. All of this has intensified the appeal of a Bitcoin ETF, or exchange-traded fund. In the U.S., maj...

GBTC: Everything You Need To Know About The Grayscale Bitcoin Trust

Grayscale's two-year battle to launch a Bitcoin spot exchange-traded fund (ETF) may finally be turning a corner. On August 29, 2023, the United States Court of Appeals for the DC Circuit sided with Grayscale over the U.S. Securities and Exchange Commission (SEC) in the crypto firm's quest to launch a Bitcoin ETF. The price of Bitcoin rose significantly following the news. Bitcoin Surges After Grayscale Wins Appeal Against SEC The Grayscale Bitcoin Trust (GBTC), which was launched in 2013, enable...

What Is Arbitrum? Speeding Up Ethereum Using Optimistic Rollups

The Ethereum network has a lot going for it—it’s decentralized, reliable, supports smart contracts written in a programming language familiar to many crypto developers, and is home to a thriving decentralized finance (DeFi) industry. However, Ethereum is also slow and expensive to use, and will remain so unless users opt to move to another blockchain (like Solana, Fantom or Avalanche), or until planned Ethereum upgrades speed things up within the next couple of years. While the world waits, a th...

What Is 'The Merge'? Ethereum’s Move to Proof of Stake

In September 2022, Ethereum made the transition from a power-hungry, proof-of-work system to an environmentally friendly proof-of-stake system. This switch is known as the "merge.” Here’s what you need to know. What is the merge? The merge changes the way that Ethereum transactions are validated. Previously, Ethereum worked like Bitcoin: transactions were mined by a decentralized network of computers, which raced to solve mathematical puzzles and were rewarded with new coins for doing so. This...

What Are Nouns? The Ethereum NFT DAO Building Open-Source IP

Pixel art NFTs are nothing new—one of the first NFT collections, CryptoPunks, pioneered the blocky 8-bit design style. But Nouns is shaking things up with a novel distribution method and open-source IP that has led to the collection's signature pixelated specs popping up everywhere from beer cans to movies. Here’s how Nouns works, and how it has built a multimillion-dollar decentralized brand. What are Nouns? First and foremost, Nouns is an NFT collection, whose owners are part of Nouns DAO, a d...

What Are Meebits? Metaverse-Ready NFTs From the Creator of CryptoPunks

Launched in 2017, CryptoPunks were one of the earliest examples of an NFT crypto collectible; a series of 10,000 pixel-art profile pictures (PFPs) with randomized traits. They proved to be a runaway success, with NFT enthusiasts paying tens of millions of dollars for the 24x24 pixel images of apes, aliens and zombies. But for CryptoPunks’ creators Larva Labs, that was only the beginning. In May 2021, Larva Labs returned with Meebits, another Ethereum-based PFP NFT project with double the supply...

What Are Fan Tokens? Crypto Assets That Give Fans a Voice

The relationship between fans and the object of their affection—be it a sports team or a band—has traditionally been something of a one-way street. Fans buy tickets and merchandise, the team or band rakes in the cash. Now a new type of cryptocurrency, the fan token, promises to change the dynamics of that relationship. What are fan tokens? Fan tokens are a type of cryptocurrency designed to provide membership benefits to fandoms of sports teams, bands and other groups. Holders of fan tokens are...

What are Dynamic NFTs? The ‘Living’ Tokens That Change Over Time

Non-fungible tokens, or NFTs, are unique digital assets that exist as a permanent record on blockchain. But if you thought that meant they were static and unchanging, think again. There is, in fact, a whole genre of living NFTs. Also referred to as dynamic NFTs, these non-fungible tokens can shift and mutate over time, according to programmable features encoded by their developers. “A living NFT is all about dynamism—as opposed to a normal profile picture (PFP) project such as CryptoPunks, which...

What Are Ethereum Rollups? A Scaling Solution to Cut Transaction Costs

Even after the latest crypto crash, Ethereum remains expensive for many to use. That’s because the Ethereum blockchain is slow and has maxed out its capacity. Now you must pay through the nose for every additional byte of block space if you are to buy the next "must-have" NFT. Until "Ethereum 2.0," the next generation of the Ethereum blockchain, resolves all of these issues, the community must rely on so-called scaling solutions: technology that speeds up the Ethereum blockchain. Scaling soluti...

What Is Terra? The Algorithmic Stablecoin Protocol Explained

Stablecoins are assets pegged to the price of a single asset, typically a fiat currency such as the dollar. The first generation of stablecoins, such as Tether, maintain their price using a basket of assets including fiat reserves. But some advocates of decentralization argue that a centralized entity maintaining a basket of real-world assets introduces a single point of failure into the system. That brings with it risks such as opacity over governance structures and whether the actual reserves...

5 Biggest 'Ethereum Killers'

In 2015, a group of crack blockchain developers unleashed the world’s first blockchain for smart contracts: Ethereum. Their creation now hosts decentralized finance applications worth over $100 billion dollars. But although it's achieved much success in its seven-year history, Ethereum has become relatively expensive to use and struggled to become scalable. Thus, rival developers have slung their rifles over their shoulders, taken aim at Ethereum, hummed "Fly Me to the Moon" and squeezed the tri...

What Is Optimism? Using Rollups to Help Scale Ethereum

Ethereum has grown to become the second largest cryptocurrency by market capitalization, thanks largely to its support for smart contracts—which underpins a growing ecosystem of decentralized applications (dapps) and decentralized finance (DeFi) platforms. But it suffers from a problem: it’s slow and expensive to use, thanks to persistently high transaction fees. While the Ethereum fraternity waits for the roll-out of planned upgrades to the network that will address these issues, scaling soluti...

How to Bridge from Ethereum to Layer 2

These days, crypto is composed of layer-1 and layer-2 technologies. Layer 1s are the base layer of a blockchain network—think Solana, Ethereum and Bitcoin. Layer-2 networks sit on top of layer-1 networks. Usually, layer 2s are faster and cheaper than the base layer of the blockchain. Sometimes, they can do things that layer-2 blockchains cannot, such as accept assets from other layer-1 blockchains. You can determine if a technology is layer 1 or not by whether you earn the platform’s native curr...

How to Read a Block Explorer

One neat thing about blockchains is that you can see all of the transactions ever processed on them. This feature, unique to public blockchains, will persist for all of time—or, at least, until someone switches the internet off. You can download a blockchain ledger for yourself and sift through it on your computer. But a much easier method is to parse this data with a tool called a blockchain explorer—a website that lets you scan through a blockchain’s entire history. Blockchain explorers suppor...

Netflix's 'Trust No One': Who Was QuadrigaCX CEO Gerald Cotten?

Netflix’s latest true crime doc, "Trust No One: The Hunt for the Crypto King", seeks to unravel the mystery of Gerald Cotten, the CEO of crypto exchange QuadrigaCX, who died in 2018. Cotten passed away from complications that arose from Crohn’s disease while on a honeymoon in India—apparently taking some $215 million of customer funds to the grave. Given the mysterious circumstances of his death—and the enormous amount of money he controlled—it’s no surprise that conspiracies quickly sprang up i...

What Is Fantom? The Fast Blockchain Taking on Ethereum

Use an Ethereum protocol on a particularly congested day and you'll surely balk at the fees, which can easily surpass the value of your trade if you are, say, swapping crypto worth no more than the change in your pocket. Help is at hand in the form of alternative layer-1 blockchains like Solana, Avalanche, and the subject of today’s lecture: Fantom. Fantom is a smart contract-supporting blockchain, powered by its native FTM token. Following a $40 million raise, Fantom launched its mainnet in Dec...

Everything You Need to Know About OpenDAO’s SOS Token Airdrop for OpenSea Users

On Christmas Eve, anyone who had ever spent money on OpenSea could claim a free Ethereum token called SOS, and the amount of SOS they’d get was determined by how much money they had spent on NFTs on OpenSea. By Sunday, about 240,000 people had claimed the token, and it had skyrocketed more than 1,000% in value. The tokens were not dropped by the popular NFT marketplace itself, but by OpenDAO, an independent decentralized autonomous organization that pledges to use some of the tokens it earmarke...
